Events/Alarms of the CS141 – Generex

Description of Alarms
The events/alarms differ depending on the UPS manufacturer.

The following example describes the events using a NEWAVE UPS as an example, which are similar in form to the alarms and necessary reactions of other UPS manufacturers.

In any case, all alarms that are not POWERFAIL, SYSTEM SHUTDOWN, BATTERY LOW, UPSMAN STARTED, or AUX must be reported to your UPS service partner, as this may indicate a hardware fault in the UPS!

The mentioned alarms are generally valid and only require a user reaction in the case of POWERFAIL and BATTERY LOW, e.g. by configuring an automated shutdown of computers via RCCMD.

UPS Event	Meaning
Powerfail	Power outage – system running on battery and autonomy time is decreasing. NOTE: RCCMD shutdowns are entered under this EVENT to initiate the shutdown of network computers in case of a prolonged power failure!
Power Restored	Power supply restored
System Shutdown	Event is TRUE when remaining time during discharge is reached or fallen below. In other words, autonomy time only a few seconds left, shutdown of the UPS is imminent.
UPSMAN Started	UPS monitoring service in the CS141 started. This EVENT is always TRUE as long as the CS141 is running and is therefore ideal for recurring tasks, such as sending emails after every UPS restart or creating log file entries at regular intervals.
UPS Connection Lost	UPS RS232 communication lost, device attempts to restore connection.
UPS Connection Restored	UPS RS232 communication restored
Battery Low	Battery autonomy has reached the programmable "Low Battery" threshold, shutdown of the UPS is imminent. NOTE: RCCMD shutdowns are entered under this EVENT, identical to the POWERFAIL EVENT, but WITHOUT delay! (Emergency shutdown when batteries become too weak must occur immediately!)
Output Breaker Open	Output breaker opened. UPS isolated from load. No supply to consumers.
Output Breaker Closed	Output breaker closed. Load can be supplied.
Maintenance Breaker Closed	Manual bypass closed (active). Load supplied directly by mains.
Maintenance Breaker Open	Manual bypass open (inactive). Load can be supplied by UPS. Normal position for UPS-protected operation.
Inverter Breaker Open	Inverter contactor open. Load is not protected by UPS.
Inverter Breaker Closed	Inverter contactor closed. Load supplied by inverter. Normal state.
Battery Breaker Open	Battery breaker open – no battery buffering active!
Battery Breaker Closed	Battery breaker closed – OK, normal state.
UPS Off	UPS off
UPS On	UPS on
New Alarm	New alarm, buzzer activated.
Buzzer Off	Buzzer off
General Alarm	An alarm has occurred. Alarm LED on UPS lights up.
General Alarm Off	No active alarm. Alarm LED on UPS is off.
Overtemperature	UPS overtemperature
Temperature Ok	UPS temperature back to normal
Output Bad	UPS output fault (e.g. voltage or frequency)
Output Okay	UPS output OK
Overload	UPS overload, reduce the UPS load immediately or shutdown is imminent.
No More Overload	No overload anymore
Bypass Bad	Bypass fault at input (e.g. voltage or frequency)
Bypass Ok	Bypass OK
UPS Shutdown Canceled	UPS shutdown procedure canceled
UPS Shutdown	UPS shutdown procedure initiated, device is switching off or has switched off.
Charger Fault	Battery charger fault
Charger Ok	Battery charger OK again
System Off	UPS output is or will be switched off
System Off Canceled	UPS output switch-off canceled
Bypass On	Bypass on
Bypass Off	Bypass off
Battery Depleted	Battery depleted
Input Bad	Power failure at input, event triggered together with Powerfail.
Mains Input Okay	Power supply at input restored
Fan Failure	UPS fan fault
Fan Ok	UPS fan OK
Awaiting Power	Waiting for input voltage before UPS automatically starts.
Shutdown Pending	UPS shutdown pending…
Shutdown Imminent	UPS shutdown imminent
Unit Powerfail	Power failure at a UPS module
Unit Power Restored	Power to UPS module restored
Redundancy Lost	UPS redundancy lost, load too high or UPS modules for redundancy no longer available.
Inverter Failure	Inverter fault
Emergency Power Off	Emergency stop, UPS has been shut down
Synchronization Error	Synchronization error between parallel modules or with input, e.g. during generator operation.
ECO Mode On	Eco mode on. Load on bypass
ECO Mode Off	Eco mode off. Load on inverter
Battery Weak	Battery weak
Battery Need Replacement	Battery needs replacement, please restart UPS after battery change.
Battery Ok	Battery OK
Rectifer On	Rectifier on
Rectifer Off	Rectifier off
