Table 4.2 Event Notification Defaults (continued)
Table 4.3 on the next page , describes events available with a Vertiv™ Liebert® MC Condenser.
NOTE: A CANbus connection between the Liebert® MC condenser and Vertiv™ Liebert® iCOM™ is required to trigger
these events.
Event Description
CAN GC 1 or 2
• The Liebert® iCOM™ board cannot establish communication with the Liebert® MC condenser board for 10
seconds consecutively.
• Alarm notification displayed for the corresponding circuit.
• Liebert® EconoPhase pump operation disabled for the circuit affected.
• When Liebert® iCOM™ re-establishes communication with the Liebert® MC board, the event is reset.
GC 1 or 2 Rem
Shutdown
• Remote shut down requested.
• Compressor(s) and Liebert® EconoPhase pump(s) in the corresponding circuit are powered-off.
• If event occurs on the lead circuit, then the lead-lag order of the compressors/tandem banks changes.
• When the Liebert® MC condenser remote-shutdown circuit returns to inactive state (closed), the event is reset
and the compressors in that circuit may be powered-on.
• Normal compressor lead-lag sequence resumes when both compressors are Off.
GC 1 or 2 Board Fail An unrecoverable failure of the Liebert® MC condenser control board has occurred causing a condenser shutdown.
GC Pres Sens Fail C1
or C2
Condenser pressure sensor failure
GC High Cond Press
C1 or C2
High condensing pressure
GC Low Cond Press C1
or C2
Low condensing pressure
GC 1 or 2 Amb Sens
Fail
Ambient-temperature sensor failure
GC 1 or 2 Amb Temp
Limit
High/low ambient temperature
GC Temp Sens Fail C1
or C2
Refrigerant liquid line temperature-sensor failure
GC High Cond Temp
C1 or C2
High refrigerant liquid line temperature
