GP Series Portable Chillers Chapter 4: Operation 50 of 93
Variable Description
Access Level
Operator Supervisor
Analog Out 3
Determines how analog output 3 is used. It can be
set to CHIL IN (retransmission of the chiller in
temperature), CHIL OUT (retransmission of the
chiller out temperature), FROM PROC
(retransmission of the from process temperature) or
TO PROC (retransmission of the to process
temperature).
x
Analog Out 4
Determines how analog output 4 is used. It can be
set to CHIL IN (retransmission of the chiller in
temperature), CHIL OUT (retransmission of the
chiller out temperature), FROM PROC
(retransmission of the from process temperature) or
TO PROC (retransmission of the to process
temperature).
x
Digital In 8
Determines how digital input 8 is used. It can be set
to START/STOP (remote start stop), NO
WARNING (normally open warning alarm), NC
WARNING (normally closed warning alarm), NO
FAULT (normally open fault alarm), NC Fault
(normally closed fault), PHASE MNTR (power
phase monitor), TMP SAFETY (high temp safety)
x
Start Mode
When Digital In 8 is configured to START/STOP
this determines if the chiller’s online status is
determined by the button on the display (LOCAL) or
digital input 8 (REMOTE).
x
Chil Cntl Sens
Determines which sensor is used to control the
chiller. It can be set to CHIL OUT (chiller out
temperature), CHIL IN (chiller in temperature), TO
PROC (to process temperature) or FRM PROC
(from process temperature).
x
Proc Cntl Sens
Determines which sensor is used to control the
process loop. It can be set to TO PROC (to process
temperature) or FRM PROC (from process
temperature).
x
Pump 2 OL Alm
When set to CRIT, the pump 2 overload alarm will
deactivate compressors and pumps. When set to
WARN, compressors and pumps are allowed to
continue to run when the pump 2 overload alarm
occurs.
x
Flow 2 Alm Type
When set to CRIT, the flow 2 alarm will deactivate
compressors and pumps. When set to WARN,
compressors and pumps are allowed to continue to
run when the flow 2 alarm occurs.
x
Alarm Out
Determines when the alarm output is activated.
When set to ALL ALARMS, the output is activated
when any new alarm occurs. When set to CRIT
ALARMS, the output will only activate when
critical alarms (those that force the pump or
compressor off) occur.
x
Network Prot
Determines what network protocol is used for
communications. This can be set to BACNET485,
BACNET IP, MODBUS485, MODBUS IP, LON or
WEB.
x
Network Baudrate Determines the baudrate for communications. x
Network Address
Determines the network address of the chiller on the
network.
x
Units
Determines if STANDARD (English) or METRIC
units are used.
