CONTROLS AND FUNCTIONS  
Using the Local Interface Display — The Local  
Interface Device (LID) is a CCN operator interface that gives  
the user the capability to view and modify all configuration and  
service data for the CC6400 control system. The LID also  
allows the user to override all point display and maintenance  
data.  
MENU STRUCTURE — The LID operates on a hierarchy of  
four levels (menus).  
The top level contains the LID’s major functions. Each  
function has a corresponding key on the LID. For an explana-  
tion of each function key, refer to Table 3.  
The second level separates the major functions (items) into  
types with corresponding type numbers that can be used for  
quick access.  
The third level gives the user the capability to access each  
occurrence of an item. For example, the application may  
require two DO (Discreet Output) — Analog Comparison

Automatic Run Test — The 50BV,XJ unit controls are  
programmed with an automatic run test that checks connection  
and operation of major components. To perform the run test:  
Verify that the control display (LID device/System Monitor)  
interface cable is connected to internal jack on main controller;  
that the fire alarm/shutdown switch input (FSD) has a factory  
jumper or field input; that Bypass (if installed) is set in the  
DRIVE position; and that the Local/Off/Remote switch is set to  
the REMOTE position.  
NOTE: When the Local/Off/Remote switch is in the  
REMOTE position, the controller time schedule is pre-set

OPERATION  
16  
COMRES triggers the compressor staging routine that  
controls the number of compressors energized. Units are  
equipped with 4 compressors piped in separate refrigerant  
circuits, and staged On/Off in a fixed sequential manner  
(compressor no. 1 through compressor no. 4). The compressor  
control routine uses a PID calculation to determine the percent-  
age of cooling required, from 1 to 100%. Demand for the PID  
calculation is determined from the supply air temperature and  
the supply air set point (SETPT06).  
Compressor cooling (COMPRES) will be turned off for any  
of the following reasons:  
There is no condenser water flow (CDWF is Off).  
Economizer Freezestat (FREEZ) has been in alarm for  
more than 15 minutes.  
MODE changes to heat.  
OK-FAN turns off during normal shut down.  
During normal compressor operation the minimum on  
time is 5 minutes and the minimum off time is 5 min.  
ECONOMIZER COOLING (50XJ) — The unit diverts con-  
denser inlet water flow through an optional economizer coil to  
precool evaporator entering airflow. This occurs when there is  
demand for the cooling, and the temperature at an Entering  
17  
Units not equipped with a water economizer can be ordered  
with the reverse/head pressure control valve factory installed  
and a pressure transducer located in the discharge line of  
compressor no. 1.  
When the condenser water temperature gets low enough to  
cause the head pressure to drop, the valve will be modulated to  
control the head pressure of all four compressors by varying  
the water flow through the condensers.  
When the unit is operating and the COOLOK software  
point is enabled and the EWT gets below 60 F, the Head  
software point will become enabled and the head pressure  
control valve will modulate to keep the head pressure at the  
head pressure set point (SETPT04). The default set point is  
225 PSI and may be set from 200 to 250 PSI. The minimum  
output value for the head pressure control algorithm is 40% in  
order to maintain a minimum flow through the condensers. The  
valve will modulate between 40 and 100%. Do not set the  
minimum lower than 40% or the compressors may shut down  
due to low flow, resulting in the high-pressure switch tripping.  
FIRE INPUT (FSD) — This is a normally closed input, which  
when opened, deenergizes an isolation relay in the unit, opening  
the input to the controller. When this input turns On, all control  
outputs are immediately turned Off, including the fan. Unit  
reset requires manual resetting at the main controller keypad.  
DUCT HIGH STATIC INPUT (DHS) — This air switch  
provides backup protection for the ductwork. It is factory  
installed in the unit, wired to the unit main controller to receive  
5 vdc. It is a normally open discreet switch, with adjustable  
manual setting at the switch (range is 1 to 5 in. wg). Upon  
switch closure, the controller immediately turns all outputs Off,  
VENTILATION REQUEST (50XJ) — The ventilation request  
output will close a set of relay contacts to activate a ventilation  
damper whenever the supply fan and supply fan status are both  
true and the TIMECLOCK software point is on.  
VAV TERMINAL OPERATION OUTPUT (50XJ) — The  
VAV terminal control output (TRMCT) closes a set of relay  
contacts to indicate to non-Carrier air terminals that the fan is  
either forced on or is going to turn on. This signals the  
terminals to open and start controlling to the desired CFM and  
Temperature set points.  
VAV TERMINAL OPEN OUTPUT (50XJ) — The VAV ter-  
minal open output (TRMOP) closes a set of relay contacts to  
command the air terminals to open to maximum CFM at times  
when the fan is operating on the VFD Bypass.  
PUMP AND TOWER OUTPUTS (50XJ) — The pump and  
Tower outputs close a set of relay contacts to indicate that the  
50XJ unit is in operation and may require condenser water  
flow through the unit.  
BUILDING PRESSURE CONTROL (50XJ) — The building  
pressure control output provides an analog 4 to 20 mA signal to  
control return fan or exhaust fan speed. Fan speed is modulated  
to maintain the building static pressure set point (SETPT07).  
The control parameters for the building pressure set point  
and building pressure are read and controlled in milliamps but  
are converted to inches of water for ease of setting and display.  
The range and low start values of the sensor selected should be  
configured in the custom configurations screen. The raw sensor  
value in milliamps will be displayed on the hardware point  
BSP. The converted sensor reading in inches of H2O will be  
displayed at the software point BSP_IN. The set point input in  
SETPT07 in inches of H2O is converted to a raw milliamp set  
point in SETPT08. The algorithm controls to the milliamp  
values since the math required for control using the static  
pressure in inches generates numbers too small to be used  
given the range of the controller configuration parameters.  
Diagnostic Features — The CC6400 provides a number  
of features to help protect the unit and allow problem  
diagnosis.  
CRITICAL FAULT — The controller provides an output  
(for field connection) to signal an external building systems  
monitor or control that the unit is not operating properly and  
has shut down. A red light mounted on the front of the unit  
provides visual indication of this alarm condition.  
NOTE: If the Local/Off/Remote switch is in the OFF  
position, it is normal for the red alarm light on the display  
panel to be lit, indicating that the unit is disabled.  
NON-CRITICAL FAULT — The controller provides an  
output for a yellow light, mounted on the front of the unit, that  
indicates the need for minor maintenance or service.  
18  
LOW-PRESSURE SWITCH (LPS) — The Low-Pressure  
Switch is located in the suction refrigerant line of each  
compressor, and is set to open at pressures below 27 psig. It is  
wired in the 115 vac control power line of the compressor

Standard Diagnostic Features, Alarm and  
Warning Lights  
DUCT HIGH STATIC INPUT (DHS) — This air switch  
provides over pressurization protection for the ductwork. It is  
factory installed in the unit. The switch is a normally open  
switch, with adjustable manual setting (range is 1 to 5 in. wg  
default setting is 3.0 in. wg). Upon switch closure, the control-  
ler outputs will be forced to off with safety forces, the alarm  
output will close and the red Alarm light will be lit. A system  
alarm will be generated and displayed on the unit keypad. Unit  
reset is automatic when the duct pressure is again below the  
switch setting minus the device hysteresis.  
COMPRESSOR MULTIPLEX (MUX) BOARD — A re-  
sistance board is used to generate a variable voltage input to the  
controller to determine compressor status. If the voltage output  
from this board gets out of the acceptable range the controller  
outputs will be forced to off with safety forces, the alarm  
output will close and the red Alarm light will be lit. A system  
alarm will be generated and displayed on the unit keypad. Unit  
reset is automatic when the Mux board has a valid reading  
again. The valid range is between 1.5 and 10 vdc. The table  
below indicates what voltages correspond to the compressor  
status indicated in the controller.  
SUPPLY AIR TEMPERATURE SENSOR FAILURE — If  
the supply air temperature sensor fails and indicates either  
245 F from a short or -40.0 F from and open sensor the control-  
ler outputs will be forced to off with safety forces, the alarm  
output will close and the red Alarm light will be lit. A system  
alarm will be generated and displayed on the unit keypad. Unit  
reset is automatic when the supply air sensor has a valid  
reading again.  
DUCT STATIC PRESSURE SENSOR FAILURE — If the  
duct static pressure sensor fails and indicates either 5.0 inches  
from a short or 0.0 inches from and open sensor the controller  
outputs will be forced to off with safety forces, the alarm  
output will close and the red Alarm light will be lit. A system  
alarm will be generated and displayed on the unit keypad. Unit  
reset is automatic when the supply air sensor has a valid  
reading again.  
FIRE/SHUTDOWN INPUT (FSD) — This is a normally  
closed input, which when opened, deenergizes an isolation  
relay in the unit, opening the input to the controller. When this  
input turns opens, all control outputs are immediately turned  
off, including the fan. Fire forces will be displayed on the  
outputs. Unit reset is automatic when the FSD input is closed

CONDENSER WATER FLOW — This is an optional  
switch that can be used with the OMNIZONE™ controller. A  
thermal dispersion flow switch detects water flowing past the  
sensor element and closes normally open contacts that energize
