Introduction
Introduction
Teledyne Analytical Instruments Series 4030 Total Hydrocarbon
(THC) Analyzer is designed to measure the quantity of hydrocarbons
present in a heated sample gas, such as gaseous mixtures or ambient air
in various industrial applications. The Analyzer is a microprocessor
controlled digital instrument based on Teledyne’s highly successful
Model 402R series Total Hydrocarbon Analyzer, coupled with carrier
gas, a switching valve and a sample draw pump (optional). This allows
for the sample into the Sample Loop kept inside a heated SAMPLE
CHAMBER and maintained at a constant temperature in the range of 50
to 120 C as per application. With a 2-position, 10 port switching valve
and Carrier Gas, the sample collected inside the Sample Loop is pushed
inside the Flame Ionization Detector (FID) and analyzed for the THC.
The sample integrity, as it enters the Analyzer, is maintained by
ensuring that condensation does not take place inside the SAMPLE
CHAMER. This is ensured by maintaining a high temperature (50 -
80°C typical) inside the SAMPLE CHAMBER. Also, the sample is
diluted with the Carrier Gas to ensure that once the mixed sample
reached FID, no further condensation takes place.
A separate SAMPLE SELECTOR MODULE unit (optional) may be
provided for use in conjunction with the Model 4030. This allows the
User to bring the heated Sample gas (Max: 120 C) and the Span gas to
the Sample Selector Unit and manually select either Sample or Span for
entry into the Model 4030. The User is responsible for making all gas
connections from the Sample point to the Sample Selector Unit and also
between Sample Selector Unit and Model 4030. The User must also
ensure that gases are heated above the dew point (Max: temp. allowed
120 C) and are cleaned to better than 2 micron filter.
1.1 Main Features of the Analyzer
The Analyzer is sophisticated yet simple to use. A dual display on
the front panel prompts and informs the operator during all phases of
operation. The main features of the analyzer include:
1. Easy-to-use front panel interface that includes a red 5-digit LED
display and a vacuum fluorescent display (VFD), driven by
microprocessor electronics.

Introduction
2. High resolution, accurate readings of concentration.
3. Versatile analysis with three user-definable analysis ranges.
4. Microprocessor based electronics: 8-bit CMOS microprocessor
with 32 KB RAM and 128 KB ROM.
5. Auto ranging allows analyzer to automatically select the proper
preset range for a given measurement. Manual override allows
the user to lock onto a specific range of interest.
6. Two adjustable concentration alarms and a system failure alarm.
7. Extensive self-diagnostic testing at startup and on demand.
8. RS-232 serial digital port for use with a computer or other digital
communication device.
9. Analog outputs for selectable concentration, analog input
waveform and range identification (0-1 VDC standard and
isolated 4-20 mA dc).
10. Superior Accuracy
1.2 Principle of Operation
The sample is brought to a heated SAMPLE CHAMBER (50 - 120°
C per application) and into a sample loop and a 10-port, 2 position
(Position A & B) switching valve. The carrier gas, typically nitrogen,
pushes the sample alternatively from each sample loop into the FID to
detect the hydrocarbons.
1.3 Analyzer Description
The standard analyzer is housed in a sheet steel equipment case
flush-mounted in a 19" rack. The front interface panel is mounted on a
door which, when opened, allows convenient access to the Analyzer
electronics. The entire front panel can slide out of the chassis to provide
greater access to the electronics and to the sample system. Gas pressure
and flow controls are mounted on the front panel adjacent to the LED
and VFD displays and user interface.
At the rear of the instrument are ports for the introduction of air,
carrier, fuel, span, and sample gas. A single 50-pin user-interface cable
connector contains input/output and alarm signals available to the user.
An RS-232 port is also available at the rear panel for connection to a
remote computer or other digital communication device. The Analyzer is
set up for either 120 VAC 60 Hz or 230 50/60Hz operations depending

on the customer’s requirements. The appropriate power cord for your
unit has been shipped with this instrument.
1.4 Applications
. Monitoring the ambient air for Total Hydrocarbons in chemical and
petrochemical plants.
. Fugitive emission monitoring.
. Process emission gases in the chemical industry.
2.1 Introduction
Using a built-in pump, the heated Sample from the Sample Selector
Unit is brought to the heated SAMPLE CHAMBER of Model 4030,
housing filter cartridge, switching valve and sample loops. Using
nitrogen carrier gas and the microprocessor actuated switching valve, a
fixed volume of sample, which is collected in Sample Loop, is pushed
into the FID detector.
Series 4030 uses a Flame Ionization Detector to sense hydrocarbons.
The FID was selected based on the positive performance and extensive
experience in the use of this detector in other Teledyne analyzers namely
Model 402R and Model 4020. The FID has proven itself to be a rugged,
stable, long life sensor giving years of trouble free operation in various
applications.
Typically, Model 4030 is calibrated using a known mixture of
methane in air, and thus the THC is shown as equivalent ppm methane
concentration.
A separate SAMPLE SELECTOR MODULE Unit (optional) may be
provided with a heated chamber (120 C Typical) and a manual 3- way
valve. This allows the User to connect Sample gas and the Span gas to
the back of the Sample Selector Unit and manually select the gas to
Model 4030 for analysis. The User must ensure that the Sample gas is
kept above the dew point to avoid condensation from the Sample point
to its entry into Model 4030.

Introduction
The Series 4030 Analyzer is composed of three subsystems:
1. Sample System
2. Detector Cell
3. Electronic Signal Processing, Display and Control
2.2 Sample System
The Analyzer contains two (2) separate isothermal chambers
controlled by individual PID temperature controllers, viewed just behind
the Front Panel. The three chambers, ‘SAMPLE’ and ‘FID are
described below.
The Analyzer consists of a SAMPLE CHAMBER containing the 10-
port switching valve and 2 sample loops. A sample filter with
replaceable filter cartridge is also included inside the Sample Chamber.
The Analyzer also consists of an ‘FID’ chamber containing the Flame,
pressure regulators, pressure gauges and flow restrictors.
2.2.1 Input Porting
The Analyzer is equipped with ports for the introduction of air, fuel,
carrier gas and sample gas. It is imperative that these gases are
supplied at constant pressures using two stage stainless steel diaphragm
gas regulators. The recommended pressure range is 30 to 60 psig.

Introduction
2.2.2 Gas Flow Control System
The Piping diagram is in the rear of this manual. A 10 port-switching
valve is used to control and direct gas flows to the FID detector. The
fixed volume sample loop ensures the same volume of sample injection
in the Analyzer every cycle.
2.2.3 Fuel and Blanket Air Systems
Stable flow is achieved by maintaining a constant pressure across
restrictors upstream from the cell. Each system incorporates an adjustable
pressure regulator, pressure gauge, and restrictor. A flame out light is
included to indicate when the flame fails. A fuel shut-off solenoid valve,
mounted on the line that supplies fuel, stops the fuel flow in case of flame
failure. This valve is located in line with the fuel port.
2.2.4 Flame Ionization Detection Cell
The carrier gas containing sample and fuel are combined within a tee
fitting located in the isothermal chamber. The mixed gas is emitted from
a burner within the sensor assembly. Blanket air is introduced into the
sensor (or cell) by means of a separate fitting that is located in the base
section of the assembly. The upper half of the assembly houses the
anode-igniter, collector, and flame guard thermistor.
2.3 Detection Cell
The upper section of the stainless steel flame ionization cell houses
the cylindrical collector electrode, the high voltage (+260 VDC) anode-
igniter coil, and the sensing thermistor of the flame guard circuit (see
cell cross-section Figure 2-1).
WARNING: DANGEROUS HIGH VOLTAGE EXISTS AT THE
ANODE IGNITER COIL (+260 VDC). DO NOT
ATTEMPT TO DISCONNECT THE IGNITER COIL
CABLE OR DISASSEMBLE ANY OF THE FLAME
IONIZATION CELL COMPONENTS WITHOUT
TURNING OFF THE POWER AND DISCONNECTING
THE POWER CORD.
The collector is interconnected with the electrometer-amplifier PC
board by a coaxial cable. Although the cable and fittings are intended for
coaxial service, the cable is actually being used as a shielded single-
conductor connection.

Introduction
The anode-igniter, as its name implies, serves two functions. When
relay K2 at PCB part number B74671 is energized, the coil becomes an
electrical heating element that glows red-hot and ignites the hydrogen
fuel. When relay K2 at B74671 is de-energized, the coil is connected to
the +260 volt DC terminal of the anode-flame guard power supply PC
board. In this configuration, the necessary potential difference is
established between the coil (anode) and collector to promote ionization
of the burned hydrocarbons. The coil functions as the high voltage anode
in all three-range positions of the selector switch.
The thermistor acts as the sensor in the flame guard circuit. Its
ambient temperature resistance is in the 100 K ohms region. When the
flame is ignited, its resistance is reduced by a factor of 100. The
thermistor is coupled to a semiconductor control circuit on the anode-
flame guard power supply PC board, which will be described in a
following section.
The cell electrodes of both the anode-igniter and flame guard
thermistor are connected to the electronics chassis by means of a plug-in
cable.

Introduction
Figure 2-1: Flame Ionization Cell
The electrode section of the cell may be removed for inspection by
turning off the power, disconnecting the electrode lead plug, and
removing the screws, which retain the electrode assembly in the sensor
body.
2.3.1 Electrometer-Amplifier
The collector cable is coupled directly to a coaxial fitting located on
the electrometer-amplifier PC board. The PC board is located on the side
panel next to but outside of the isothermal chamber. See Figure 2-1 and
consists of an electrometer amplifier and an operational amplifier. This
circuit is a very high-gain, current-to-voltage converter circuit, having
an input impedance measuring in the billions of ohms. It is static
sensitive and highly susceptible to contamination. Special care must be
taken in handling this PC board.
2.3.2 Anode Power Supply
The high voltage anode power supply components are mounted on
the anode power supply printed circuit board. High voltage regulation is
achieved through the use of series-connected zener diodes. The
simplicity of this circuit’s design can be attributed to the extremely low
current demand of the anode circuit. The positive output voltage is

Introduction
nominally 125 volts. Output tolerance is ±10 volts from the specified
125 volts.
2.3.3 Flame Guard Circuit
A thermistor-controlled, transistorized switching circuit is employed
to operate a relay in the event of a flameout condition. A panel indicator
light and fuel shut-off solenoid valve are operated by the relay to alarm
personnel that a flameout condition has occurred. The fuel shut-off
solenoid valve stops the hydrogen flow.
2.3.4 Flame Ignition Circuit
The flame ignition circuit includes the anode-igniter electrode (in the
detector cell), a transformer, and processor-controlled relay. The circuit
is automatically energized when the FID cools due to lack of flame.
If automatic ignition fails five times, there will be a message that
reports this, and the flame can be manually ignited by pressing
simultaneously the Up and Down key.

Installation of the Series 4030 Analyzer includes:
1. Unpacking
2. Mounting
3. Gas connections
4. Electrical connections
5. Testing the system.
3.1 Unpacking the Analyzer
Although the Analyzer is shipped with all the materials you need to
install and prepare the system for operation. Carefully unpack the
Analyzer and inspect it for damage. Immediately report any damage or
shortages to the shipping agent.
3.2 Mounting the Analyzer
The Series 4030 and the Sample Selector Unit are general-purpose
units and as such are designed with (non-sealed) enclosures. They must
be installed in an area where the ambient temperature is not permitted to
drop below 40ºF nor rise above 100ºF. In areas outside these
temperatures, auxiliary heating/cooling must be supplied. The 4030
enclosure is oil and dust resistant and although it is designed to resist
moisture, it should NOT be considered completely watertight. Mounting
to walls or racks must be made securely. Avoid locations that are subject
to extreme vibration and sway.
Sufficient space must be provided around the analyzers to
accommodate the necessary electrical conduit and plumbing connections.
The front panel must be allowed to be pulled out for possible service
access to all components of the enclosure. Refer to the system/analyzer
outline drawings for dimensions.
Note: To completely slide the Model 4030 Analyzer out of the
enclosure, pull Analyzer out until it stops, and then push down on the
release levers found almost at the end of the sliders, both sides at the
same time.
Teledyne Analytical Instruments

Installation
Regardless of configuration, the analyzer/system must be installed
on a level surface with sufficient space allocated on either side for
personnel and test equipment access. Subject to the foregoing, the
Analyzer/system should be placed as close to the sample point as is
possible.
All pertinent dimensions, connecting points, and piping details can
be found in the drawings section as part of the outline, input-output, and
piping diagrams. These drawings are specific to the instrument or
system to which the manual applies.
3.3 User Connections
All user connections are made on the rear panel. Consult the input-
output and outline diagrams in the drawing section of the manual. Not
all the features displayed may be present in your system. Refer to any
Addenda for additional information that may apply to your instrument.
3.3.1 Electrical Power Connections
The standard analyzer requires a supply of 100-125VAC, single-
phase power. Power connections are made at the rear panel of the unit.
Refer to the input-output diagram for more information. The electrical
power service must include a high-quality ground wire. A high-quality
ground wire is a wire that has zero potential difference when measured
to the power line neutral. If you have the 220 VAC option, you will
require 220 or 240 VAC, 50/60 Hz power. Check the analyzer input-
output diagram, power schematic, outline, and wiring diagrams for
incoming power specifications and connecting points.
CAUTION:
PRIMARY POWER TO THE SYSTEM SHOULD NOT
BE SUPPLIED UNTIL ALL CUSTOMERS WIRING IS
INSPECTED PROPERLY BY START-UP PERSONNEL.
3.3.2 Gas Connections
The analyzer gas connection diagram identifies the various gas
connection points as to function and location. Figure 3-1 shows the gas
connection points for Model 4030 and SAMPLE SELECTOR
MODULE (optional).

Installation
Figure 3-1: Gas Connections
Gas connections to the instrument are made at the 1/8”or 1/4”
stainless steel tube fittings provided on the rear panel. Note that the
Purge and Sensor Vent fittings are 1/4” while all other gas connections
are 1/8”.
If the Sample line is heat traced to avoid condensation, the User
must ensure that a clean (2 micron or better filter) and heated sample,
maintained at a constant temperature not exceeding 120 C, is delivered
to the Sample Selector Module and the connection between the Sample
Selector Module and the Model 4030 is similarly heat traced. The
Sample Selector Unit contains provisions to accept tubing diameter in
the range of 1.25 to 1.50 inches, typically the O.D. of the heat-traced
lines.
It is recommended that all gas tubing leading to the connections on
the back of the analyzer be of the coiled type. This will facilitate sliding
the unit out of the case without disconnecting the gas supply to the
analyzer.

Installation
Before tubing is connected to the system, it must be decontaminated
to rid it of hydrocarbon deposits. Using a small torch, heat each length
of tubing, while passing nitrogen through it, until it glows red. Begin at
the nitrogen source end and proceed down the length of the tube,
“chasing” the red glow (and hydrocarbon deposits) down to the open
end of the tube. Cap tubing while not in use with suitable non-
contaminating caps.
All sample, calibration, and supporting gas lines, which deliver gas
to the analyzer, must be decontaminated before connection; vent lines do
not.
When connecting the various gas lines to the system, be absolutely
certain that no “dead ends” are left; that is, no unused branch lines
should be left capped off, where pockets might form of material that is
not representative of the current contents of the line, or which might
keep contaminants from being purged out of the system.
CAUTION: THE GASES USED MUST BE OF THE
HIGHEST QUALITY, ULTRA ZERO GRADES, AS SHOWN
BELOW. FAILURE TO DO SO WILL RESULT IN
CONTAMINATION AND FAILURE TO DETECT LOW
CONCENTRATIONS OF HYDROCARBONS.-
AIR: USE ULTRA ZERO GRADE, WATER PUMPED, AIR WITH
THC LESS THAN 0.1 PPM.
FUEL: USE ULTRA HIGH PURITY (UHP) GRADE HYDROGEN
GAS, 100%, WITH THC LESS THAN 0.5 PPM.
CARRIER GAS: USE ULTRA HIGH PURITY GRADE
NITROGEN GAS, WITH THC LESS THAN 0.1 PPM.
3.3.3 Electrical Connections

3.3.3.5 ALARM RELAYS
The nine alarm-circuit connector pins connect to the internal alarm
relay contacts. Each set of three pins provides one set of Form C relay
contacts. Each relay has both normally open and normally closed contact
connections. The contact connections are shown in Table 3-4. They are
capable of switching up to 3 amperes at 250 VAC into a resistive load.
The connectors are:
Threshold Alarm 1:
Can be configured as high (actuates when concentration is above
threshold), or low (actuates when concentration is below
threshold).
Can be configured as failsafe or non-failsafe
Configured as latching or non-latching
Can be configured out (defeated).
Threshold Alarm 2:
Can be configured as high (actuates when concentration is above
threshold), or low (actuates when concentration is below
threshold).
System Alarm:
Actuates when power is removed from analyzer.
It is triggered if 4030 fails to ignite after five times.
The System Alarm may be reset by selecting the
STANDBY function in the menu to send to sleep mode,
then press the ENTER or ESCAPE key to restart the
analyzer. However, if the condition that caused the 4030 to
fail ignition is not remedied, the 4030 will likely fail to
ignite again, and the System Alarm will be re-triggered.
Further detail on flame ignition failure can be found in Chapter 4,
Section 4.3.1.

3.3.3.6 RANGE ID RELAYS
There are three dedicated Range ID relay contacts. They are
assigned to relays in ascending order—Low range is assigned to Range
1 ID, Medium range is assigned to Range 2 ID, and High range is
assigned to Range 3 ID. Table 3-6 lists the pin connections. Contacts
are normally open, and they close when 4040 switches to that particular
range.

3.3.5 Supporting Gases
Normally, four supporting gases of different composition (see
Section 4.1: Equipment) will be required to operate the analyzer. The
recommended composition of these gases is specified in the Application
Data section of the Appendix. The gases should be supplied from
cylinders that are equipped with the type of regulator specified in the
aforementioned sections.
CAUTION:
UNDER NO CIRCUMSTANCES SHOULD YOU
EMPLOY A REGULATOR THAT IS NOT EQUIPPED
WITH A METALLIC DIAPHRAGM ANYWHERE IN THE
SYSTEM.
The regulators should be inspected prior to installation to be sure
that they are oil-free. Failure to comply with these directives will result
in a constant drift in analyzer output, as organic compounds will outgas
into the plumbing system at a rate that is related to the ambient
temperature. Use 316 stainless steel, dual-stage stainless steel diaphragm
regulators only in fuel, sample, and blanket air lines; shutoff valves
should be used downstream from each regulator.
Place the supply cylinders as close to the analyzer as possible, and
interconnect them to the analyzer with new tubing. Be sure that all
plumbing connections are free of leaks.
Note: Use only stainless steel tubing throughout the system.
Consult the assembly, piping, outline drawings, and any
Addenda included with this manual to determine if special
conditions apply.

Installation
CAUTION: THE GASES USED MUST BE OF THE
HIGHEST QUALITY, ULTRA ZERO GRADES, AS SHOWN
BELOW. FAILURE TO DO SO WILL RESULT IN
CONTAMINATION AND FAILURE TO DETECT LOW
CONCENTRATIONS OF HYDROCARBONS.
AIR: USE ULTRA ZERO GRADE AIR WITH THC LESS THAN
0.1 PPM. DO NOT USE OIL PUMPED AIR UNDER ANY
CIRCUMSTANCES.
FUEL: USE ULTRA HIGH PURITY (UHP) GRADE HYDROGEN
WITH THC LESS THAN 0.5 PPM.
CARRIER GAS: USE ULTRA HIGH PURITY GRADE
NITROGEN GAS, WITH THC LESS THAN 0.1 PPM.
3.3.5.2 EFFLUENT
All the gases introduced into the detection cell vent from one fitting
at the rear of the analyzer. TAI recommends that the cell be permitted to
vent directly to the atmosphere wherever possible.
If a vent line is required, the installation must include a drop-out pot
to collect the water that is formed by the burning of the hydrogen fuel.
The vent line must be constructed so that water and dirt cannot collect in
it.
3.3.5.3 SAMPLE BYPASS VENT
The sample bypassed by the back-pressure regulation system vents
from a separate port at the rear of the analyzer. If a vent line is required,
it must be installed so that water and dirt cannot accumulate in it.
3.3.5.4 FUEL AND AIR CONNECTIONS
The fuel used to provide combustion should be Hydrogen gas, zero
quality with certified THC of less than 0.5 ppm and a pressure of 30
psig. The compressed air, ultra zero gas quality with THC less than 0.1
ppm should be used at a controlled pressure of 30 psig Connect the fuel
and air sources to the instrument according to the gas connection
diagram included at the back of this manual.

Operation
Operation
4.1 Placing the System in Operation
1. Plug the power in the AC power inlet in the back of the Analyzer
and the Sample Selector Unit.
2. Allow at least 2 hours warm-up (heat up sensor & sample
system) after making the air adjustment described below. Warm
up time is set by the software at the factory but may be
overridden by pressing the <ENTER> key.
DO NOT attempt to ignite the flame during warm up
countdown. Condensation will occur.
4.2 Activating the Support Gases
4.2.1 Air
1. Set the air tank regulator to 30 psig.
2. Adjust the Analyzer Air regulator until the air pressure gauge
reads the recommended air pressure of 9 psig.
After the air is flowing through the sensor and warm-up time has
been completed, activate the following gases:
4.2.2 Carrier Gas
Set the Carrier gas tank regulator to 50 psig and adjust the Analyzer
Sample regulator until its (sample) pressure gauge reads the
recommended sample pressure of 9.5 psig.
4.2.3 Span Gas
The Span gas containing certified mixture of methane in
air, recommended range 6 to 8 ppm methane in zero grade
air, may be connected to the Span Manifold or the ¼ inch
connection on the back of the Sample Selector Module.

Operation
the temperature controller is maintaining the temperature set point) and
the red flame failure lamp is on. See Figure 4-1.
The Series 4030 will automatically attempt a flame ignition
sequence following the warm up period, which has been preset at the
factory. If the ignition process fails, the instrument will attempt to ignite
the flame 4 more times. If it continues to fail after the fifth attempt, a
flame failure message will appear on the display. If this occurs refer to
Section 4.3.1.
4.3.1 Verification of the Flame Guard Circuit
The operation of the flame guard circuit has been checked at the
factory, but should be re-verified during start-up. Use the following
procedure after ignition of the flame has been achieved:
1. Turn off the fuel at the supply cylinder.
2. Observe the fuel pressure gauge on the analyzer control panel. The
gauge indication will decay as the fuel in the line is exhausted.
When the gauge reading reaches the vicinity zero, the flame will
be extinguish as the fuel solenoid shuts off the fuel supply. The
analyzer will automatically try to re-ignite. After 5 attempts, it will
display: flame failure, check air, fuel and the flame failure LED
will be on.
3. Open the cylinder supply valve and re-ignite the flame by
pushing the UP and DOWN buttons simultaneously.
4.3.2 Ignition and/or Flame Guard Circuit Failure
If the flame ignition or guard circuits do not operate as described in
the above two sections, set the instrument fuel regulator to the
recommended pressure.
4.3.3 Sample Pump
A built-in Sample Pump is provided to draw Sample Gas from the
Sample line. The gas flow rate should be maintained at about 1000 to
1200 cc/minute using the Front Panel FLOW CONTROL valve
(clockwise increases flow).
4.4 Analyzer Operation
Although the Model 4030 has been programmed for your application
at the factory, it can be further configured at the operator level.
Teledyne Analytical Instruments

Operation
Depending on the specifics of the application, this might include all or a
set of the following procedures:
1. Setting system parameters
1. Establish a security password, if desired, requiring operator
to log in
2. Establish and start an automatic calibration cycle (not
available)
3. Choose auto ranging or select a fixed range of analysis
4. Set alarm set points and modes of alarm operation
5. Calibrate analog output, select analog output source.
2. Routine operation
1. Calibrate the instrument
Procedures for accessing and/or changing parameters as well as
analyzer operation are detailed in the sections to follow. In general, the
sequence of menus available on screen follows a logical course for setup
and operation. It is not required, however to follow this sequential path.
The user could, for instance, go directly to set an analysis range and then
program an offset to the current output for matching a range on the
user’s recording device. The only exception to this is when the
instrument is powered up. It will go through a warm-up period, followed
by a diagnostic self-test routine.

4.4.3 Navigation and Data Entry
Note: All menus time out after 15 (fifteen) seconds elapse with
no button presses, the analyzer returns to the ANALYSIS
SCREEN, if parameters have been altered but not saved
(with the ENTER key), the alterations are lost.
Navigation and Data Entry is possible using 2 ARROW KEYS, the
ENTER key, and the ESCAPE key. It is important to read and
understand the MENU STRUCTURE section to fully understand
navigation and data entry.
4.4.3.1 ARROW KEYS
Pressing the ARROW KEYS select menus and modifies values.
1. In the ANALYSIS SCREEN, the ARROW KEYS cause
entry into the MAIN MENU.
6. When the selected option is a function on the MAIN MENU
or any SUB MENU screen, the ARROW KEYS move to the
next lower or upper menu.
7. If the selected option is a MODIFIABLE ITEM (value is
flashing), The ARROW KEYS increment or decrement
numeric values or toggle ON/OFF, YES/NO, or
ENABLE/DISABLE type values.
4.4.3.2 ENTER
The ENTER key is used in several context-sensitive ways.
2. When showing the THC analysis mode, the ENTER key
toggles the LINE 2 display.

3. When the selected option is a function on the MAIN MENU
or any SUB MENU screen, the function name appears with
an arrow next to it. In some cases, the item in the menu is
the parent of another SUB MENU; in other cases, the item in
the menu is the parent of a MODIFIABLE ITEM.
8. If the selected option is a MODIFIABLE ITEM, the ARROW
KEYS are used to modify the value of the item. A modifiable
item is flashing. The ENTER key is then used to accept the
value and move you to the next field to continue programming.
4.4.3.3 ESCAPE
The ESCAPE key is used in several context-sensitive ways.
4. When showing the THC analysis mode, the ESCAPE key
temporarily clears any present alarms. However, if the alarm
condition is still present, the alarm will re-occur when re-
detected. Also, pressing the ESCAPE key clears the
messages generated by incorrect gain settings (i.e. bad span,
gain too high).
When the selected option is a function on the MAIN MENU
or any SUB MENU screen (the menu name appears with a
flashing arrow next to it), the ESCAPE key is used to return
to the parent menu finally returning to the ANALYSIS
SCREEN the function.

4.4.5 Setting up an AUTO-CAL
AUTOCAL is not available for standard configurations of the
4040.
4.4.6 Adjusting the GAIN
The output of the FID is conditioned by an amplification circuit with
3 user-adjustable settings:
0) x1
1) x10
2) x100
The resulting signal is converted to a number. Numbers outside the
range –262144 to 262143 are unreliable and lead to inaccurate
measurements. If the number is outside this range during analysis, the
message 'GAIN TOO HIGH' is shown on the 2nd line of the display, and
the analyzer is not updated to a new, calculated value. The Gain Too
High message may be removed by pressing the ESCAPE key.
The gain has been set at the factory such that the analyzer will work
reliably within the prescribed range of operation. The user may change
the gain when a different level of sample is to be analyzed.

this reflects a gain of x10.
4.4.6 Password Protection
Before a unique password is assigned, the system assigns TAI by
default. If the password is the default, it will be displayed automatically.
The operator just presses <Enter> from the any of the MAIN MENU
items to be allowed access to that item's sub menu. If the password has
previously been changed from the default then the initial display will be
'A' 'A' 'A', and the correct letters must be input.
If user has LOGGED OUT, then only the following SUB MENU
procedures may be executed:
14. PASSWORD
15. LOGOUT (which only repeats the logout)
16. MODEL
Teledyne Analytical Instruments

Operation
Note however, that the instrument can still be used for analysis
without entering the password. To defeat security the password must be
entered.
Note: If you use password security, it is strongly advised to keep
a copy of the password in a separate, safe location. If the
password is lost and security is enabled, the analyzer must
be cold-booted. Cold booting invalidates parameters
necessary for correct operation so they must be re-
entered.
ENTERING A PASSWORD
To install a new password or change a previously installed password,
you must key in and ENTER the old password first. If the default
password is in effect it will be displayed as the default gausses for each

4.4.7 Logging Out
The LOGOUT function provides a convenient means of leaving the
analyzer in a password protected mode without having to shut the
instrument off. By entering LOGOUT, you effectively log off the
instrument leaving the system parameters protected until the password is
reentered. The system will continue analysis, however.
To log out:
<▲▼>
From the MAIN MENU scroll to field of LOGOUT
function.
<Enter>
Press <Enter> to logout .
The screen will display the message:

Pressing <Enter> will logout the current user and protect the system
from unauthorized changes to parameters.
If user has LOGGED OUT, then only the following SUB MENU
procedures may be executed:
17. PASSWORD
18. LOGOUT (which only repeats the logout)
19. MODEL
Note however, that the instrument can still be used for analysis
without entering the password. To defeat security the password must be
entered.
4.4.8 The Model Screen
The MODEL screen displays the model, and software version
information. It is accessed via the MAIN MENU by scrolling (▲▼> to
MODEL and pressing <Enter>.
4.4.9 System Self-Diagnostic Test
The Model 4030 has a built-in self-diagnostic testing routine.
Preprogramming signals are sent through the power supply, output
board, preamp board and sensor circuit. The return signal is analyzed,
and at the end of the test the status of each function is displayed on the
screen, either as OK or BAD. If any of the functions fail, the System
Alarm is tripped.
Note: The self diagnostics are run automatically by the analyzer
whenever the instrument is turned on, but the test can also
be run by the operator at will.
Note: The self diagnostics will interrupt analysis temporarily.
To initiate a self-test:
<▲▼>
From the MAIN MENU scroll to the SELF-TEST
function.
<Enter>
Activate the SELF-TEST function by pressing <Enter>.
This brings up the SELF-TEST initialization screen.

Operation
The first line determines whether a span calculation will be performed
for THC. The second line determines whether a span calculation will be
preformed for SMP. The third line allows the user to modify the span
target value for THC calibration. The fourth line allows the user to
modify the span target value for SMP.
The last line commences the span (after the following query:
________________________________________________
Begin Span:
ENTER-YES ESCAPE-NO
________________________________________________
Pressing <Enter> enters the SPAN mode in the SMP phase first.
The first pass in the SMP phase only purges the sample gas from the
column (no span calculation is performed this time around). Then the
THC is span calibrated followed by the second pass of the SMP mode,
where the span calculation is performed. The 4030 goes through all of
these phases, but span values are only adjusted if the user selected YES
in the initial menu for the respective phase.
4.4.11 The Alarms Function
The Model 4030 is equipped with two alarms and a system failure
alarm relay. Each alarm relay has a set of form "C" contacts rated for 3
amperes resistive load at 250 VAC. See Figure in Chapter 3, Installation
and/or the Interconnection Diagram included at the back of this manual
for relay terminal connections. The alarm relay contacts are accessible to
the user from the 50-pin Equipment Interface connector.
The system failure alarm has a fixed configuration described in
Chapter 3 Installation.
The concentration alarms can be configured from the ALARM
function screen as follows:
________________________________________________
-> AL-1 DEFEATED
AL-1 HIGH
AL-1 NON-FAILSAFE
AL-1 NON-LATCHING
Teledyne Analytical Instruments

Operation
AL-1 20.00 ppb
AL-1 SOURCE THC
AL-2 ACTIVE
AL-2 LOW
AL-2 FAILSAFE
AL-2 LATCHING
AL-2 50.00 ppb
AL-2 SOURCE SMP
________________________________________________
Note: For the purpose of example, Alarm 2 has been set differently
than Alarm 1.
Note: An alarm in 'alarm condition' is signaling that action must be
taken such as correcting the alarm or the analysis concentration. If an
active (not defeated) alarm has been set to HIGH at 20.0 ppb, and the
analysis concentration is above that level, then the 'alarm condition' is
occurring.
DEFEATED: If an alarm is defeated, its relay is de-energized,
regardless of failsafe condition. A defeated alarm does not react to a
transition over its trip point in either direction.
HIGH: If an alarm is set as HIGH, it will not create a new alarm
condition (see latching) if the analysis concentration is below the trip
point, if the analysis concentration is above the trip point, then an alarm
condition will be created or maintained.
FAILSAFE: A non-defeated alarm that is in FAILSAFE mode
energizes an alarm relay in a non-alarm condition and de-energizes an
alarm relay in an alarm condition.
Note: Failsafe condition of an alarm is in software. This is not
related to relays that have both normally-open and normally-closed
terminals.
LATCHING: The latching property configures the alarm such that
the user must manually relieve the alarm condition even though the
concentration no longer violates the trip point of the alarm. So, if an
alarm is NON-LATCHING, and the analysis concentration temporarily
drifts above the trip point of a HIGH alarm, the alarm condition occurs
Teledyne Analytical Instruments

Operation
only during the time the concentration is above the trip point. If that
alarm were LATCHING, the alarm condition would persist (even though
the concentration is no longer above the trip point), until the user
released it.
RELEASING A LATCHED ALARM: When alarm conditions are
present, the main analysis screen will have one of the following
messages: 'AL1-', 'AL-2', 'AL12'. Pressing ESCAPE (in the
main/analysis screen) will release a latched alarm and defeat the alarm
until the pertinent phase is re-completed.
TRIGGER POINT: This is the threshold at which an active alarm
can enter into alarm condition. If an alarm is HIGH, ACTIVE, and set
at 20.00 ppb, then when the analysis concentration is at or above 20.00
ppb an alarm condition is initiated or maintained.
SOURCE: The alarm can react to measurement levels of THC,
SMP, or AVG (the average of the previous 2).
CAUTION:
IT IS NOT GOOD PRACTICE TO SILENCE AN
EXISTING ALARM BY SETTING THE ALARM
ATTRIBUTE TO ‘DEFEAT”. THE ALARM WILL NOT
AUTOMATICALLY RETURN TO “ACTIVE” STATUS.
IT MUST BE RESET BY THE OPERATOR BY
PRESSING THE ESCAPE BUTTON. IF IT IS NOT
RESET, YOUR PROCESS WILL BE RUNNING
WITHOUT SAFEGUARDS THIS INSTRUMENT IS
DESIGNED TO PROVIDE.

Operation
The value of the upper limit of the currently selected range (AUTO
or MANUAL) affects the voltage and current of the analog outputs on
the rear of the analyzer as well as contact closures indicating which
range is current. The Analog outputs on the rear of the analyzer
represent the proportion of the analysis concentration to the currently
selected range limit.
MANUAL/AUTO RANGE SELECT: In Manual Range select, the
Range indicated on the second line 'Man Rng:' is maintained as the
current range of operation. In Auto Range select, the software
determines the smallest range whose limit is larger than the analysis
concentration.
AUTO RANGE SOURCE: The automatic selection of range can be
set to select according to the THC, SMP, or AVG concentration.
RANGE LIMITS: Ranges may be set as low as 2.0 ppb and as high
as 9999.99 ppm. Range 3 can only be set at a value greater than Range
2. Range 2 can only be set at a value greater than Range 1.
4.4.13 Changing Stream
CHANGE STREAM is not available for standard configurations
of the 4030.
Affects the relay on the rear panel that controls which gas is allowed
to flow to the column and detector.
When the instrument has electronically controlled calibration valves,
the gas stream can be switched here. You can set the incoming gas
source to span, sample (or zero gas, which is nothing more than a 3rd
source of gas) without entering the calibration mode in order to check
instrument response. During a span calibration, the span stream is
activated. After a span calibration, the stream reverts to whatever was
set before the span. This value is not remembered if the power in cycled
on the unit, the analyzer will default to the analyze stream.

ONLY. To access the offset function:
<▲▼>
From the MAIN MENU, scroll to the ANALOG
ADJUST function using the UP/DOWN keys.
<Enter>
Pressing <Enter> activates the function and takes you to
the next screen.
ANALOG-OUT ADJUST
-----------------------
CH1 Offset: 0
CH1 Gain:
0
CH1 Select: THC
CH2 Select: R-ID
-----------------------
<Enter>
Use the <Enter> key to move over to the Offset field.
Use the UP/DOWN keys to change each digits value.
Use the <Enter> key to save the value.
<▲▼>
<Enter>
<Escape>
Use the <Escape> key to revert to the original value.
Use the same procedure to set the gain of the instrument. After the
last digit is entered, the final <Enter> press will accept the gain value.
The values entered do not have explicit units of current or voltage.
Adjustment should be gauged using a voltmeter or current meter
attached to the analog output. When the ANALOG ADJUST menu is
entered the following is displayed:
________________________________________________
-> CH1 mA Offset: 0
CH1 mA Gain: 0
________________________________________________
When the arrow is on the Offset, or when the user presses <Enter> to
modify the offset, the analog output is 4mA plus a value that is
proportionate to the number indicated to the right of 'Offset:' That
number may be modified –500 to 500.
When the arrow is on the Gain, or when the user presses <Enter> to
modify the gain, the output is 20mA scaled by the value to the right of
Teledyne Analytical Instruments

Operation
'Gain: ' plus the Offset value plus a value that is proportionate to the
number indicated to the right of 'GAIN:'.
If these 2 values are modified and entered and accepted, then the
analog output will be affected in like manner in ANALYSIS MODE.
That is, it will be scaled by the gain value, then summed with the offset
value.
The analog output for each channel may be set to source THC, SMP,
AVG, WAVE, or R-ID. In the case of THC/SMP/AVG, the output will
reflect the percent of range for the respective selection. In the case of
WAVE, the output will track the FID output. In the case of R-ID, the
output will reflect the selected range: LOW: 1/5 of full scale, MID: 1/2
of full scale, HIGH: 4/5 of full scale.
4.4.15 Standby
This function allows you to place the instrument in STANDBY.
CAUTION:
