Input/Output
Description
Action
1 Input Operate Unit
High input will start the UNIT. With Low input the UNIT
will stop. UNIT must be in “remote operation” mode for
this input to be active.
2 Isolated Ground Common line for remote inputs.
3 Output
Indicate Set Point 1
Active
Contact closure: indicates that unit is OK and set-point 1
is active and no alarms present. Signal present
irrespective if UNIT in LOCAL or REMOTE operation
4 Indicate Common Indicate common for all output contact closures
5 Output Indicate Power On
Contact Closure: indicates that power present Signal
present irrespective if UNIT in LOCAL or REMOTE
operation
6 Indicate Common Indicate common for all output contact closures
9 Input Remote Operation
High input will put UNIT into remote operation. Low input
will revert the UNIT into local mode
10 Output Indicate Standby
Contact Closure: Indicates that cooling circuit 1 is in
“standby”. Signal present irrespective if UNIT in LOCAL
or REMOTE operation
11 Input Operate Cool (1)
High Input: puts the UNIT cooling circuit 1 into COOL.
Input low: reverts the UNIT to Standby mode. UNIT must
be in “remote operation” mode for this input to be active.
12 Output Indicate Cool (1)
Contact Closure: Indicates that cooling circuit 1 is in
“COOL”. Signal present irrespective if UNIT in LOCAL or
REMOTE operation
13 Input Operate Defrost (1)
High Input: puts the UNIT cooling circuit 1 into DEFROST.
Input low: reverts the UNIT to Standby mode. UNIT must
be in “remote operation” mode for this input to be active.
14 Isolated Ground Common Line for remote inputs
15 Output Indicate Defrost (1)
Contact Closure: Indicates that cooling circuit 1 is in
“DEFROST”. Signal present irrespective if UNIT in
LOCAL or REMOTE operation
16 Output
Indicate Defrost
Complete (1)
Contact Closure: Indicates that cooling circuit 1 has
completed defrost. During Defrost the contacts will open.
Signal present irrespective if UNIT in LOCAL or REMOTE
operation
17 Indicate Common Indicate common for all output contact closures
21 Input
