Description
An unrecoverable fatal system error has occurred. Pump shut down. Pump board must be
rebooted to reset event.
Pump has cavitated and was shut down. Event is reset when the Liebert iCOM requests a
new startup.
Inlet refrigerant pressure sensor failure. Pump shut down. Event is reset when condition
clears.
Inlet refrigerant temperature sensor failure. Pump shut down. Event is reset when condition
clears.
Invalid data detected and pump was shut down. Event is reset when the Liebert iCOM
requests a new startup.
Pump differential pressure fell below a lower threshold and pump was shut down. Event is
reset when the Liebert iCOM requests a new startup.
Pump outlet refrigerant temperature fell below a lower threshold and pump was shut down.
Event is reset when the Liebert iCOM requests a new startup.
Outlet refrigerant pressure sensor failure. Pump shut down. Event is reset when condition
clears.
Outlet refrigerant temperature sensor failure. Pump shut down. Event is reset when condition
clears.
