UPS IN FAULT CONDITIONS 

 

If the UPS experiences the fault, the normal status message will be replaced with the alarm one. 
An alarm message will differ depending on the type of fault which occurred. Activated sound signal can be 
switched off by pressing the ESC key. The ENTER (< >) key can be used to display the list of indications 
which let the operator to understand the meaning of the alarm. The <BACK or NEXT> keys can be used to 
scroll through all the active alarms. When  the alarm cause disappears, the LCD will return to the  default 
message. 

 
 
 
 
 

 
 
The possible alarms and associated with them help messages are listed below. 

 

ALARM MESSAGE 

MEANING 

INVERTER OFF

 

 

The load is no longer supplied by the inverter 
and subject to any mains failures 

INVERTER OVERLOAD

 

 

The inverter is off due to an overload and the load 
is supplied by the reserve network 

STATIC SWITCH LOCKED

 

 

After 3 unsuccessful automatic switching attempts from 
the reserve to inverter, the UPS blocks the static switch 
in the reserve network position 

BATTERY TEST FAILURE

 

 

Displayed whenever the periodic test on the battery 
fails for any reason 

BATTERY PRE-ALARM

 

 

At the battery voltage of around 345V the UPS warns 
the user of a low battery voltage 
At 320V discharging ends and the UPS switches off 

STATIC SWITCH FAILURE

 

 

At least one of output phases is missing 

MANUAL BYPASS ON

 

 

The manual bypass switch has been closed 

MAINS OUT OF LIMITS 

The mains voltage is out of allowed specification, 
it might be out of the range allowed by the system, or 
simply not present 

BY-PASS OUT OF LIMITS 

The reserve is out of allowed specification, it might be 
out of the range allowed by the system, or 
with incorrect cyclic direction, or not present 

EMERGENCY POWER OFF

 

 

Displayed whenever the E.P.O. button is pressed 

PARALLEL DATA EXCHANGE 
FAILURE

 

 

This alarm occurs when there is, for any reason, no 
data exchange between UPS units in parallel. 
It may be due to a missing or incorrect connection 
of one or more parallel fibers 

BATTERY CHARGER FAILURE

 

 

Battery charger doesn’t work properly or is not 
connected
