Installation  
Installation Location  
The UNIPRO instrument is designed for 1/8 inch panel mounting in  
a DIN standard opening of 5.43 inches square (adapter panels  
available by special order). Required rear clearance is 10.5 inches  
to allow for wiring. As with all solid state equipment, the  
controller should be away from excessive heat, humidity, and  
vibration (refer to specifications). Since the unit uses red LED  
display devices, avoid placing it in direct sunlight to reduce  
interference with the display's visibility. The instrument requires  
100/120/200/240 VAC (jumper selectable on power interconnect  
board inside the rear panel) 50/60 Hz. It should not be on the  
same circuit with other noise-producing equipment such as  
induction machines, large electrical motors, etc. All instrument  
wiring must be run separate from all control wiring.  
Panel Mounting/Removal  
Because the instrument uses a ventilated enclosure, it is not  
dust-tight and should therefore always be mounted in a sealed  
control panel. To mount the UNIPRO in a control panel, a hole  
must be cut 5.43 inches square in the necessary location on the  
panel. The following procedure should be followed to mount the  
UNIPRO in the panel.  
1.  
Insert the unit into previously cut out 5.43 inches square  
hole in the panel.  
2.  
While supporting the unit, insert one slotted clamping  
bracket, with head of the bolt facing to the rear of the unit, into the  
0.62 inch by 0.82 inch cutout on the side of the unit.

3.  
4.  
Repeat step 2 for the opposite side of the unit.  
With 1/8 inch HEX KEY wrench, alternately tighten bolts  
on either side of the instrument to a torque of 4 in-lbs. (See warning  
below). Insure rigidity of mounting.  
Warning  
To prevent warping of the unit's case, do not over tighten the  
clamp bolts.  
5.  
To remove the unit, loosen the side clamping brackets and  
reverse steps 1 through 3 above.  
Note  
Unipro 3.5 Process Control  
1 Aug. 1997  
Marathon Monitors Inc.  
On subsequent removals and installations the rear  
panel can be removed (4 screws) and the wiring  
does not have to be disturbed.  
Warning  
All connections, rear panel installations and removals; plus  
triac board installations and removals must be done with  
power removed from TBA and TBB. All PC boards should  
only be removed or installed with power off via the switch  
mounted on the triac board. Otherwise, serious personal  
and/or equipment damage can occur.  
Thermocouples and Other Signal Wires  
The wiring used to connect the signal wires to the instrument  
should be run in a conduit, separate from any AC lines in the area.  
This provides noise immunity and physical protection.  
Thermocouples should be wired with the appropriate alloy  
extension wire with no termination other than at the instrument. As  
with all cold-junction compensating instruments, extreme care  
should be used when an existing thermocouple is to be used for  
both the Controller and another instrument at the same time.  
Control Devices  
The UNIPRO provides simple ON/OFF as well as Proportional  
control through its two contact closure Control Outputs (TBA-7,  
TBB-7, TBA-8, and TBB-8) and two Analog Outputs (TBD-13  
through TBD-16). Refer to the Section on Control Modes for  
more details on the outputs. This allows control through simple  
ON/OFF devices or through Proportional control methods.  
SIMPLE ON/OFF CONTROL: Set Control Mode for  
ON/OFF Control. This provides contact closure at Control Output  
#1 to control absolute heat application/removal for such devices as  
heating elements, etc.  
Unipro 3.5 Process Control  
1 Aug. 1997  
Marathon Monitors Inc.  
Three types of Proportional control are:  
1.  
Time-Proportioning: Referring to the  
modulation of the duty cycle. That is,  
changing the ratio of On Time versus Off  
Time in systems that use such devices as  
heating elements, electronically  
operated/assisted valves, or servo drives that  
use analog command signals for control.  
2.  
3.  
Position-Proportioning: Referring to the  
adjustment of a variable positioning device  
such as a positioning motor with slidewire  
feedback.  
Voltage or Current Output Proportioning:  
An Analog output's (voltage or current)  
amplitude is varied based on input from  
rheostats, thermocouples, ammeters, etc. to  
control heat applications.  
The UNIPRO provides many ways to use the above control  
methods. Setup has details for setting the Control Modes to  
determine the method to be used. Some typical applications for the  
Proportioning method are:  
1.  
HIGH/LOW or HEAT COOL heat application system: Set  
Control Modes for Time-Proportioning. This provides that  
CONTROL OUTPUT #1 (TBA-7, TBB-7) and CONTROL  
OUTPUT #2 (TBA-8, TBB-8) are in opposite conditions at either  
extreme of the control range and are both OFF at the midpoint of  
the control range.  
2.  
ANALOG OUTPUT control: Set Control Modes for  
Time-Proportioning. This provides a 0 to 5 VDC or 4 to 20 mA  
output which is selectable on the ANALOG OUTPUT BOARD  
(TBD-13 through TBD-16, see Section 2.14 and Section 8.0 for  
Unipro 3.5 Process Control  
1 Aug. 1997  
Marathon Monitors Inc.  
more details). The output control is based on 0 to 99% of the  
output device's control range. For example, 50% control would  
equal 2.5 VDC out where 5 VDC equals maximum heat output of  
the drive. This can be used with servo drives that require a voltage  
or current command signal for controlling heat output or servo  
positioning.  
3.  
POSITIONING MOTOR with SLIDEWIRE FEEDBACK:  
Set Control Modes for Single Position-Proportioning with slidewire  
feedback. CONTROL OUTPUT #1 will drive the motor in the  
open direction, CONTROL OUTPUT #2 in the close direction.  
Remember, the above methods are just examples of the typical  
applications of the UNIPRO. Please call your MMI representative  
or application engineer for questions concerning your particular  
system.  
Chart Recorders  
If a chart recorder is to be used, it must have input specifications  
within the following ranges:  
0 to 4 VDC  
0 to 45 mA  
corresponding to a FRONT PANEL display of 0-2000. The ideal  
location of the recorder is adjacent to the instrument but it may be  
located remotely if the connecting wires are properly shielded.  
Long wiring runs from the chart recorder outputs may require  
resistive termination  
(2 K ohms or so) at the chart recorder input(s) should be isolated  
from ground.  
Computer Interface  
If you wish to take advantage of the UNIPRO's RS-422 digital  
communications capabilities, refer to "Communications" for more  
details.

Electrical Connections  
Connections to the unit are made via four terminal blocks, on the  
rear panel, labeled TBA, TBB, TBC, and TBD. (Position 1 is at  
the top the position 10 (TBA and TBB) or 18 (TBC and TBD) is at  
the bottom of the terminal strip.) AC power, event, control, and  
alarm connections are made on TBA and TBB. All  
communications are on TBC and all analog I/O signals are on TBD.  
Refer to the Figure below for a complete layout of the UNIPRO  
rear panel connections.

Analog Inputs  
The UNIPRO allows for three analog inputs with their individual  
functions determined by "daughter board" located on the analog  
input board inside the unit. The standard connection, at TBD, will  
have the first input as a thermocouple, the second for the oxygen  
probe, and the third optionally used to input voltage or milliamp  
signals.  
Analog Outputs  
Two, separate, isolated analog outputs are provided on TBD and  
can be selected as 4-20 mV (for maximum accuracy, see  
Specifications for further details) or 0-10 V output through DIP  
switch settings on the analog output board. Additionally, outputs  
can be calibrated by placing a jumper on the two terminals supplied.  
DIP Switch Setup  
The user may use the UNIPRO in a multi-instrument system by  
giving the instrument a unique HOST address, specified by using  
the DIP switches on the Interface Board inside the UNIPRO  
To get to the DIP switches, loosen the black knurled knob on the  
front panel by turning in a counterclockwise direction. Carefully  
remove the front panel but DO NOT remove the ribbon cable  
connecting the front panel to the Interface Board. Safely support  
the front panel near the instrument. Adjust the DIP switches per  
Section 2.16 for the desired operating mode. When switch  
adjustment is complete, replace the front panel to prevent  
contamination.

UNIPRO 3.5  
OPERATION  
Once installation and setup  
and configuration are complete,  
the day to day operation needs of  
the UNIPRO depend upon the  
application. The basics are found  
in the Quick Reference Guide.  
TO RESPOND TO ALARM  
MESSAGES:  
Note the alarm and  
determine what caused the alarm.  
Press [ENTER] once to  
deactivate (silence) alarm  
relay contact and continue  
program execution.  
After acknowledging the alarm, one of the  
following actions may be appropriate:  
Abort the program by pressing the  
[Prog/Auto/Man] key.  
In the case of a timed-out LIMIT  
statement (message #93), it is normally  
desirable to continue the program by  
re-executing the offending LIMIT  
statement to be sure it is satisfied. This is  
done automatically when the [ENTER]  
key is pressed to acknowledge the alarm.  
If you do not want to re-execute the  
LIMIT statement, pressing the [SETPT]  
key will cause the LIMIT statement to be  
skipped and the program to continue to  
the next STEP.  
Rev. 11.00  
December 30,1995  
MMI Product Documentation  
Correct the problem or do what  
the programmed alarm indicates: see  
“Maintenance and Troubleshooting”: the  
alarm messages for complete information  
on programmed alarms. Then press  
[Enter] to continue the program.  
If any alarm is only to be acknowledged and the operation is to  
continue, press [ENTER] to silence the alarm and then press  
[SETPT] to skip to the next operation.  
CHANGING THE SETPOINT  
AND THE REFERENCE NUMBER  
[SETPT] is used to enter the setpoint, the Reference  
Number, and the Operator Inputs. The first press of [SETPT]  
will allow the arrow keys to adjust the value of the setpoint.  
Use the [LEFT ARROW] or [RIGHT ARROW] keys to select  
the character to be altered. Once the character to be changed  
is flashing, use the [UP ARROW] or [DOWN ARROW] keys to  
select the desired number or symbol. After all characters are  
as desired, press [ENTER] to place the value in nonvolatile  
memory and to continue paging through the parameters.  
Pressing [ENTER] again allows the Reference Number to be  
changed. Pressing [SHIFT] at any time allows the operator to  
“back up”to the to the step before [ENTER] was pressed. An  
additional press of [ENTER] allows the operator Input to be  
changed. Anytime during the setting of values [SETPT] may  
be pressed to save the value and exit.  
All the parameters in this group have a lock level of 3.

PROG/AUTO/MAN  
The Operation Mode for control  
of programs is selected by the  
[Prog/Auto/Man] key. Pressing  
this key allows access to the  
operation mode selection controls.  
The first selection, after pressing  
[Prog/Auto/Man], allows for  
control of the program to be  
entered. The key presses that  
follow it depend upon the state of  
the program. If a program is not  
running see “Running A Program”  
below. Anytime during the  
selection process [Prog/Auto/Man]  
may be pressed to exit the selection  
process. All of the parameters  
under this key have a Lock Level  
of 3.  
MANUAL MODE.  
In Manual mode the process  
variable is displayed in the  
PROCESS display, the SET  
display shows the appropriate  
control value, and no control  
action is computed. The arrow  
keys can also be used to activate  
the control output.

Operation  
UNIPRO 3.5  
Either the percent ON time  
(time-proportion) or valve position  
(position proportion) is displayed  
in the SET window. For single  
control mode operation this  
number is always positive  
(0/50/100). The [UP ARROW] and  
the [DOWN ARROW] keys  
increase or decrease the percent  
ON time or the valve position  
toward its fully opened or closed  
positions by approximately 1%.  
This continues for as long as the  
key is pressed. The [RIGHT  
ARROW] and [LEFT ARROW]  
keys force the CONTROL  
OUTPUTs to increase or decrease  
the percent output by  
approximately 10%.  
AUTOMATIC MODE  
In Automatic Mode the process  
variable is displayed in the  
PROCESS display, the  
SETPOINT is displayed in the  
SET display, and control action is  
computed based upon the PID  
parameters and the input(s).  
Pressing and holding the [LEFT  
ARROW] key will cause the SET  
display to show the control action  
as described previously in  
"Manual Mode.”

Operations  
Introduction to  
Programming  
Techniques  
The UNIPRO Programmer  
uses a step/OPCODE  
approach rather than a  
segment approach.  
The advantages of using  
OPCODES (operation  
code) are:  
1) only what is to be  
changed is entered,  
2) features can be added to older instruments,  
and  
3) less information needs to be saved for each  
step therefore more programs can be stored.  
The step approach is very similar to what an operator would  
do if he were manually controlling the process.  
Some of the features in the OPCODEs may not be obvious as  
to how they would be used until more experience is gained.  
However, with a little practice and experimentation the  
Programmer can soon be mastered.  
Each program in the UNIPRO consists of nineteen steps (one  
OPCODE per step). Some OPCODEs allow programs to be  
linked together. The UNIPRO can store up to 200 programs in  
non-volatile memory.

Limit Statements  
There are various ways to force a program to wait for  
something to happen. Although it may seem that the specified  
condition should be easily satisfied, it is still wise to put  
realistic time limits on how long the wait should be.  
The following chart summarizes the effect the LIMIT  
statement has on each OPCODE.

An alarm 93 is displayed and/or

not followed by a branch. If the  
condition is not met by the time listed in  
the data statement, the unit will display  
and/or sound an Alarm #93. If the  
alarm need only be acknowledged and  
operation is to continue, press Enter  
once to silence the alarm and then press  
Setpt to skip the LIMIT OPCODE and  
resume operation.  
Rev. 11.00  
December 30, 1995  
MMI Product Documentation  
The operation of a limit statement after the following  
OPCODEs is described in more detail below:  
E (EVENT) (INPUT)  
- A limit statement here will  
cause the program to wait  
for the specified event  
INPUT (normally event  
numbers 8-15) to switch to  
the specified state (ON OR  
OFF, 1 OR 0), before  
proceeding. If this does not  
occur within the specified  
limit time, a limit time-out  
alarm will occur.  
Note: The event INPUT must be  
held in the trip state for at least 30  
seconds to make sure that the  
Programmer will acknowledge it.  
Thus, a momentary push button  
could not be used as an event  
INPUT unless some type of  
latching scheme is employed.  
If a limit statement is not used, the  
program may wait indefinitely.  
Unipro 3.5 Process Control  
1 Aug. 1997  
Programming  
Unipro3.5  
H (TEMPS)  
A limit statement  
here will cause the program to wait  
for the measured temperature to  
come to within +10 F (or +10 C) of  
the specified Setpoint. If this does  
not occur within the specified limit  
time, a limit time-out alarm will  
occur. If no limit statement is  
used, the Programmer simply sets  
the specified Setpoint and goes on  
to the next step. The maximum  
time that a limit statement will  
accept is 40 hours. Use the  
Programmer Status Display during  
a wait operation to reveal the time  
left before a limit time-out alarm  
will occur.  
Branch Statements  
Branch statements are best utilized when placed after inquiry  
statements. If neither a branch nor a limit statement is placed  
after an inquiry the Programmer will sit at the inquiry line  
indefinitely. A branch statement can immediately follow an  
inquiry or it can placed after the limit statement, for example:  
INQUIRY  
BRANCH  
or  
INQUIRY  
LIMIT  
BRANCH  
The effect of a branch after an inquiry is to jump to a specific  
line in the program based upon the outcome of the inquiry.  
The format of the branch OPCODE is b TT.FF; therefore if  
the outcome is true the program jumps to the step number  
listed first. Whereas , if the outcome is false, the program  
jumps to the second step.  
Rev. 11.00  
December 30, 1995  
MMI Product Documentation  
A limit statement between an inquiry and a branch just sets a  
definite time to wait for the inquiry to become true. It has no  
effect on the outcome of the inquiry or where the program  
branches to. It only effects the length of the time delay.  
If a branch statement is not preceded by an inquiry, or any  
conditional statement, the branch is automatically assumed  
TRUE.  
An unconditional branch is one in which the steps specified for  
true and false are the same. An unconditional branch to step 1  
(b 01.01) will cause a program to loop back to the beginning of  
the program every time the above statement is encountered.  
The difference between a b 01.01 and a J 0000 is that the jump  
reloads the program and would therefore pick up any changes  
edited into the program after it was initially started.  
Writing and Editing a Program  
Writing  
Before a program can ever be written into the UNIPRO, the  
author must understand and perform the following process:  
1.  
2.  
Determine what the program is to do,  
Write, revise, and rewrite an algorithm  
(program in words) until part 1 works,  
Construct the program for the UNIPRO  
using the OPCODEs listed in  
3.  
"Programmer Alphabet".  
The Programmer Editor can be used to create a new program  
or modify an already existing program. While in Program Edit  
mode, the unit continues to control the furnace (as long as the  
Auto LED is on), and a running program continues if the  
program LED is on.  
The Editor Mode:  
Unipro 3.5 Process Control  
1 Aug. 1997  
Programming  
Unipro3.5  
To get the unit into the editor mode, perform the dual-key  
operation [Shift][Setpt.] The PROCESS window will have the  
message EDIT displayed and the SET window will have a  
XXXX displayed signifying the program number to be edited.  
At this point any of the 200 programs can be called into the  
edit space using the arrow keys to change the necessary digits.  
That is, the [left arrow] or [right arrow] keys can be used to  
select the digit to be changed and the [up arrow] or [down  
arrow] keys can be used to select 0 through 9.  
Next, press the [Enter] key once more to begin entering or  
modifying the program. The PROCESS display will show step  
01. The OPCODE character is also displayed in the PROCESS  
display while the SET display will show the DATA line in  
various formats depending on the OPCODE character. To  
advance through each step of the program use the [Enter] key;  
to move backwards in the program use the [Shift] key.  
At any point, a step can be inserted or deleted. To insert a  
step, press Control Parm, this forces the OPCODE at step 19 to  
be lost and a -(NOP) will appear. To delete a step, press  
[Alarm Set key], this causes a - NOP to be pulled in at step 19.  
Use the [left arrow] or [right arrow] keys to determine whether  
the OPCODE or DATA is to be changed. If a data character is  
flashing move left or right in the data by using the arrows. If  
the OPCODE needs to flash press the [left arrow] until the  
OPCODE character flashes the [right arrow] does not allow  
access to the OPCODE. If the OPCODE is to be changed, the  
[up arrow] or [down arrow] keys can be used to scroll through  
the OPCODES alphabetically. If either the "up arrow" or  
"down arrow" keys are held down, the OPCODEs will  
automatically be displayed with each flash of the display.  
When entering data, the "up arrow" and "down arrow" keys  
can be used to select 0 through 9 (or negative sign, if  
applicable).  
Rev. 11.00  
December 30, 1995  
MMI Product Documentation  
If at any point [Enter] or [Shift] is pressed and the SET display  
starts flashing, the data is not valid for the OPCODE shown.  
Use the arrow keys to alter the data as required and press  
[Enter] or [Shift] to continue entering or editing the program.  
Exiting  
Once all 19 steps have been entered or modified as needed and  
the editor is sitting at step 19, press [Enter] one more time to  
get the message SAVE displayed in the PROCESS window.  
The program number, the number of the program originally  
pulled into the edit space, will appear in the SET display but  
can be changed using the arrow keys.  
If the program number is changed at this point, however, the  
edited program will be stored as the new number. For  
example, it is possible to call up program #29, edit it, and store  
it back as program #4. The original #29 is still intact, and  
whatever was in program #4 is now replaced with the edited  
#29.  
If, while entering data an error is made, or it is desired to exit  
the editing routine without making any changes, press Setpt  
and the unit will continue normal operation. The edited  
information will be lost.  
NOTE:  
It is recommended that program #200 be kept as  
a "garbage" program location to temporarily  
store programs as required.  
Programmer messages are displayed when inputting data and  
using the Editor, refer to the table shown below:

Effect of Start-up Sequence on Programmer  
The two start-up options described in "Start-Up Procedures"  
affect the Programmer significantly.  
If a Shift-Shift-Enter start-up was used, the program running  
at the time of power was lost will pick up where it left off. This  
includes events and soak times will be picked up with an  
accuracy of +4.8 minutes.  
If a simple Enter-Enter start-up sequence was used, the  
program is canceled. All events will return to the rest position  
(OFF) and the setpoint is lost.

Alarm Messages  
Programmer alarms interrupt Manual display,  
as discussed in "Keyboard Operations". This  
prevents important error messages from being  
lost while the Manual display is activated.  
Once any of the following alarms are displayed  
and/or sounded, the dual-key operation  
Shift/"down arrow" cannot be used until the  
alarm is silenced by pressing Enter. This does  
not clear the alarm, however.  
Programmer Alarms appear at Event 0 on the  
Optomux board.  
To respond to alarm displays (#01-#98)  
1.  
Press Enter one time to deactivate alarm  
relay contact (silence).  
2.  
Examine the display to determine the origin of  
the system alarm:  
Messages #01-79:  
Indicate a programmed alarm (from an  
"A-ALARM" OPCODE in the program) has  
occurred. The response should be to carry out  
whatever task the message code indicates. For  
example, Message #37 might mean put test pins  
in furnace, while #28 might mean to manually  
change the temperature setpoint to 1550`F.  
These codes should\d be assigned for the  
particular installation involved.  
Message #80-#81:  
Rev. 8.00  
November 30, 1995  
MMI Product Documentation  
Used, in conjunction with the Programmer, for the  
following purpose:  
81  
TURN ON A TEMPERATURE  
DEVIATION BAND ALARM  
(COMMUNICATING TEMPERATURE  
CONTROLLER REQUIRED)  
80  
TURN OFF SAME  
The A(Alarm) OPCODE in this case should be followed by the  
L(Limit) OPCODE that sets the width of the particular  
deviation band  
(i.e. +10`,+25` or +12%C, etc.). If no LIMIT statement is used,  
the previous deviation value will be used. Both the turn ON  
and turn OFF statements can set the deviation. The alarms are  
said to be "smart" in the sense that they are not armed until  
the process is actually at the required setpoint. If tripped, the  
alarms produce the standard programmer ALARM display  
and pulsing alarm. The program remains in HOLD until  
action is taken.  
Also, after the Deviation Alarm 81 occurs, clearing the alarm  
also clears the inb and flag; therefore, the process must reach  
setpoint before the alarm can sound again. The alarm is  
automatically disarmed at the end of a program.  
Message #82-90:  
Not assigned.  
Message #91:

Message #92:  
Indicates a problem on the Events Buss. This error may  
occur at any point in a program that attempts to use events

c.  
There is severe disruption of  
communication due to use of wrong cable,  
too long a cable run, routing of cable in  
non-recommended termination schemes  
(i.e. WYE), or improper or missing  
termination resistor connections.  
Message #93:  
Indicates a limit statement has timed out. This must be  
interpreted in the particular situation, but if the limit time  
specified in the program was realistic, then a flaw in the system  
is indicated, or an instrumentation or operator error has  
occurred.  
Message #94:  
Not assigned.  
Message #95:  
Indicates an illegal ramp, the r OPCODE is not followed by the  
H OPCODE in the currently running program.  
Message #96:  
Indicates that a power failure has occurred and the UNIPRO  
started up again in the AUTO RESTART mode as determined  
by DIP Switch 5 on Bank 1.

Message #97:  
Indicates that a subroutine is calling a subroutine which is  
illegal with the MMI Programmer.  
Message #98:  
Indicates that a jump from one program to another was  
attempted but not implemented due to memory disruption or a  
J201 to reference number too large.  
Message #99:  
Not assigned.  
3.  
After taking the required action based upon the  
alarm message, there are several possible courses  
of action:  
a.  
Press Enter again to continue with  
the program (after either correcting the  
problem with the temperature or events  
buss in the case of error message #92, or  
taking the prescribed action in the case of  
programmable messages 01 through 89).  
b.  
Abort the program by pressing  
PROG/AUTO/MAN.  
c.  
In the case of a timed-out limit  
statement, (message #93), it is normally  
desirable to continue the program by  
re-executing the offending limit statement  
to be sure it is satisfied. To do this,  
simply press Enter. A setpoint will cause  
the LIMIT statement to be skipped and  
the program to continue on the next step.

Calibration Procedures  
The UNIPRO instrument is shipped completely  
precalibrated. The drift characteristics of the  
input circuits are excellent but from time to  
time adjustment may be necessary in order to  
maintain high accuracy.  
Analog Input Calibration.  
There are three analog inputs and a  
cold junction compensation sensor on the  
UNIPRO. The input level and input features  
for each input are determined by changeable  
daughter boards that are mounted piggy back  
on the analog input board. There are several  
types of input daughter boards: thermocouple  
input, auxiliary input, 4 to 20 mA input, 0 to  
10 V linear, RTD, and slide wire input.  
The standard factory configuration is  
for input A to be a thermocouple input, input  
B to be an Oxygen probe input(auxiliary input)  
board, and input C to be a slidewire feedback  
input. If the instrument to be calibrated does  
not have the standard factory configuration,  
then identifying the configuration is necessary  
so that the proper procedure for each input  
board can be followed.  
Calibration Displays And Keyboard  
When operating in the calibration  
mode, the displays and front panel keys take on  
special assignments. The PROCESS display  
shows the value of the input being calibrated  
with a flashing digit. This flashing digit shows  
the relative sensitivity of the arrow keys, as  
Rev. 11.00  
December 30, 1995  
MMI Product Documentation  
described following the key descriptions. The  
SET display shows which input is being  
calibrated and whether the zero value or the  
span value is being modified.

NOTE  
It is very important to be sure the SET display

Adjustment Sensitivity  
The adjustment sensitivity works in the  
following manner. If the digit farthest right in  
the process display is flashing, then each press  
of the [Up Arrow] or [Down Arrow] key will  
change the calibration value shown by one  
unit. This is the least sensitive position. If the  
digit farthest left is flashing, then each press of  
Rev. 11.00  
December 30, 1995  
MMI Product Documentation  
the [Up Arrow] or [Down Arrow] key will  
change the calibration value by a thousand  
units. The middle digits will show sensitivities  
of a hundred and ten units respectively. It is  
not important to know the relative worth of  
one calibration unit. Understanding that the  
location of the flashing digit affects change that  
one key press will make on the calibration  
value is necessary. By observing the degree of  
sensitivity one key press makes at each flashing  
digit location, you can quickly see how to use  
this feature.

Preparing For Calibration  
Before placing the UNIPRO into calibration  
mode, check to be sure that for each input:  
The proper thermocouple  
type has been selected, and  
Cold Junction compensation has  
been selected, if required. Cold Junction  
compensation can be selected by using the  
[Setup] key. The option is below the  
corresponding input type selection.  
The UNIPRO is placed into calibration mode by connecting a  
jumper from TBD-17 to TBD-18. To make sure of the integrity  
of the calibration factors, power should be applied to the  
UNIPRO before this jumper is installed and not removed until  
after this jumper has been removed. The UNIPRO should be  
operating for at least 30 minutes before calibration to make  
sure that input circuits have stabilized.  
For each input of the UNIPRO, follow the calibration  
procedure by the type of input board installed for that input.  
Once an input has been calibrated, be sure to press the [Enter]  
key to make sure that the latest calibration factors are stored.  
Calibration Of The Thermocouple Board  
This calibration procedure assumes that a  
thermocouple has been selected and internal cold junction  
compensation is being used. If this is not true, follow the  
procedure for the auxiliary board using a 0 to 40 millivolt  
signal. The calibration procedure is as follows:  
Connect the input to be calibrated  
to a junction compensated calibrator (IE:  
Biddle Instrument Co. Versa-Cal  
Calibrator) using the proper extension  
wire for the thermocouple type selected.  
Rev. 11.00  
December 30, 1995  
MMI Product Documentation  
Using the [Display] key, select the  
proper input to be calibrated (input A, if  
standard configuration).  
Using the [Enter] key, select the  
zero mode (IE: if for input A, Z-A).  
Set the calibrator output to the  
recommended zero value for the  
thermocouple type selected. See the table  
below.  
Using the Arrow keys, adjust the  
process value to equal the calibrator  
output.  
Press the [Enter] key to select the  
span mode (IE: S-A, for input A).  
Set the calibrator output to the  
recommended span value in for the  
thermocouple type selected.  
Using the arrow keys, adjust the  
process value to equal the calibrator  
output.  
Repeat steps f. through j. until no  
additional change is needed.  
Press the [Enter] key one more  
time to be sure the calibration factors are  
stored. Go to the next input to be  
calibrated or exit calibration mode by  
removing the calibration jumper or  
pressing [Setup] .

over that range. Follow the  
calibration procedure for  
normal calibration with the  
following changes. Use the  
low end of the desired range  
as the zero value and the  
high end as the span value.  
There will be more  
interaction between zero  
and span with this method.  
The desired operating  
range must fit with the  
limits of the table.

Turn off the power  
at the simulator.  
Short the input by putting a banana plug  
shorting block into the simulator. Short the  
jumper ( switch) wired into 17 and 18 to  
calibration mode.  
This will produce some value in the PROCESS  
window and Z-A in the SET window.  
Use the left and right arrow keys to change the  
adjustment from coarse to fine in the PROCESS  
window, and the up and down arrow keys to  
change the value. Adjust the PROCESS window  
value to zero (0), or as close as possible.  
Press the [Enter] key twice to store the value.  
Press the [Display] key to change the SET  
window to Z-B or Z-C and repeat steps 4 and 5  
for inputs B and C.  
After all the values are stored, press the [Display] key to return  
the SET window to Z-A and press the [Enter] key to change it  
to S-A (span).  
To set the span  
Put the meter leads into the banana plug to  
measure mV (300----).  
Remove the jumper block from the simulator.  
Using a meter to check your input voltage on the  
O2 side, enter 1.4 or 1.5 mV from the simulator,  
and turn ON the simulator.  
Set the span values at 1400 or 1500 (depending  
on what the simulator generated) using the  
arrow keys to adjust the values.  
Press the [Enter] key twice to save the values and  
press the [Display] key to change the input type.

the simulator to see if the instrument returns to a  
steady 1500 at all inputs.  
Vary the input millivoltage down and verify that  
1500 reduces to 1000 at a steady level for each  
input setting.  
Check the reference voltage on TBD-5 and 6 (for  
input B) and 8 and 9 (for input C). Should read  
around +2 mV (between 1.8 and 2.2 is considered  
good).

UNIPRO is suitable for  
connection to a host  
computer for intelligent  
overall process monitoring  
or supervision. Terminal  
connections are made on  
the rear panel: See the

"X" Protocol  
The "X" protocol software  
involves a Parameter Table,  
a Program Run Buffer, a  
Program Edit Buffer, and a  
Serial I/O Program Buffer.  
The UNIPRO can be  
written to using a  
"1TXparameternumber$da  
ta" format. This entry  
would place the data value  
in the proper location as  
determined by the  
parameter number. Any  
parameter can be read back  
from the UNIPRO using the  
following format  
"1Txparameternumber".  
Therefore, to write a value  
to the UNIPRO for a  
specific parameter use an  
"X" or to read a specific  
parameter from the  
UNIPRO, use an "x".  
All of the parameters are  
listed below along with a  
short description. The  
numbers in the parenthesis  
are in Hexadecimal.*

An Alarm Queue is included in the host  
communications capabilities of the instruments. The Alarm  
Queue is simply a block of storage locations for the  
programmer alarms that occur within the instrument and  
works similar to the idea of FIFOs (first in, first out). The  
queue was added because various programmer alarms can  
occur and be acknowledged and/or corrected before the Host  
Unipro 3.5 Process Control

Maintenance and Troubleshooting  
Unipro 3.5  
Software ever has the chance to "see" them. Therefore, the  
alarms had to be passed on to the Host Software even if they  
were already acknowledged and/or corrected. The Alarm  
Queue was created to meet this need.  
The Alarm Queue works on a READ & CLEAR basis.  
If the Alarm Queue is read with the "x" parameter FF (Hex),  
the storage location will return a word comprised of a HI byte  
and a LO byte. The LO byte is the first alarm appearing in  
memory while the HI byte is the second alarm appearing in  
memory (thus creating the FIFO effect). If both bytes are  
non-zero, then the Host will look again to see if any non-zero  
values have been stored. Once the bytes are read from the  
Queue, they are cleared out of the memory block.  
If there is no Host Software used, the Alarm Queue is  
never read, but the Queue is still written to by the instrument.  
Once the Queue is filled, it cannot be written to until a location  
has been cleared. Considering the fact that Host Software is  
not used, the Queue will never be cleared and will never store  
any of the alarms that occur after the Queue has been filled.  
This does not cause a problem considering the fact that the  
Queue is only used with Host Software and if the software is  
not used, we do not care if it is filled or not.

OPTOMUX Protocol  
The OPTO 22 format is RS-422, Full-Duplex, 1200 BAUD, 8  
bit, no parity, and 1 stop bit. The message format follows the  
OPTOMUX two pass protocol. The UNIPRO sends messages  
to set up the events board per the events partition, activate the  
appropriate outputs, and reads the input conditions. The  
UNIPRO initiates messages on this buss and waits ½ second for  
a reply.  
Rev. 8.00  
November 30, 1995  
MMI Product Documentation  
The Events Buss allows the Controller to receive and/or  
transmit discrete events in time. The XMT and REC LEDs  
indicate whether the OPTOMUX is transmitting or receiving  
data. (These LEDs should never be on at the same time.) This  
actual input/output switching is executed by the OPTOMUX  
board: see “Setup and Configuration” or “Programmer  
Operations” or the OPTO22 manual for specific details.  
Slave Buss  
The slave buss is a broadcast only communications buss.  
Broadcast Mode  
The slave buss broadcasts the UNIPRO setpoint using the  
10PRO broadcast protocol. The broadcast protocol format is

Load Line  
Load line (LdLn) is a  
manual offset to the control  
output (manual reset). The  
load line can be set from 0  
to 100%. Load line must be  
set to zero when using  
ON/OFF control.  
ON/OFF control  
In ON/OFF control Output  
l is turned ON whenever  
the percent output exceeds  
l0% and Output 2 is turned  
ON whenever the percent  
output goes below -l0%.  
Therefore the proportional  
band is used to set the  
deadband. If the  
proportional band is set at  
5% then an error of 5 will  
produce a l0% output;  
therefore, the deadband is  
5. Reset and Rate would  
normally be set to zero;  
however, experimentation  
could improve the control  
response. Load Line must  
be set to zero.  
Position with Feedback  
Unipro 3.5 Process Control  
1 Aug. 1997  
Glossary  
Unipro 3.5  
This mode is used with  
slidewire feedback. Output  
l is used to drive for more  
feedback and Output 2 is  
used to drive for a smaller  
feedback. The percent  
output is used as a setpoint  
for the slidewire feedback.  
A deadband of .5% is used  
to prevent hunting.  
Position without Feedback  
This mode is used with a  
motorized valve with no  
feedback. The change in  
percent output is used to  
compute a drive time as a  
percent of the cycle time.  
For example, if the cycle  
time is 30 seconds and the  
percent output changes  
from 40% to 60% then  
Output l will be ON for 6  
seconds (20% of 30  
seconds). If the change was  
in the opposite direction  
then Output 2 is turned  
ON. If the percent output  
is at its limits (0 or l00 for  
single, and l00 or -l00 for  
dual) then the appropriate  
output will remain ON  
continuously.  
Proportional Band  
Rev. 11. 00  
December 30, 1995  
MMI Product Documentation  
The proportional band is  
based upon a range of l000.  
Therefore, if the  
proportional band is set at  
10% and the error is 100  
(10% of range) then the  
output would be 100%  
(presuming reset=0).  
Rate  
The rate setting is in  
minutes and is settable  
from 0 to 9.99 minutes in .0l  
steps.  
Reset  
The reset setting is in  
repeats per minute. The  
range is 0 to 99.99 repeats  
per minute in .0l steps.  
Time Proportion  
In time proportion mode  
Output l is ON for the  
percent of the cycle time  
when the percent output is  
plus. When the percent  
output is minus, Output 2 is  
ON for the percent of the  
cycle time.

any college digital systems text, such as  
Microcomputer-Based Design by John B.  
Peatman.  
3.  
Put all of the separate HEX digits  
together to form the numerical word.  
i.e. CF3DH*  
4.  
Therefore, the HEX representation  
CF3DH is numerically equivalent to the  
Binary representation  
01011100111100111101 or the Decimal  
number 53,053.

Hexadecimal code is an extremely helpful  
number representation when coding  
computer systems. Recall that most  
addressing systems for microprocessors  
involve 16 binary bits which convert to  
four HEX digits and 8 binary data bits  
that convert to two HEX digits. The HEX  
system allows very long binary numbers  
to be represented in a must shorter way.  
Many of the responses to the MMI  
Controller's Serial Communications  
questions are in HEX. Therefore, in  
order for the user to correctly interpret an  
answer, a clear understanding of the  
Hexadecimal number system must be  
attained.  
*
An H is written after hexadecimal  
numbers to signify that the number is  
hexadecimal, it is not part of the actual  
number value.
