INVERTER FAULT
CALL SUPPORT DEPT.!
A fault has occurred in the inverter module requiring servicing by the after- sales support department.
INVERTER SHUTDOWN
OVERLOAD > IMAX | ! |
An overload greater than 1.6 In has occurred on the load, resulting in inverter shutdown.
INVERTER SHUTDOWN
OVERLOAD > IN | A |
An overload between In and 1.6 In has occurred on the load, resulting in inverter shutdown. The blinking "A" at the end of the message is a prompt to read the load current measurement.
AUXILIARY CONTROL
SIGNAL RECEIVED !
An auxiliary "Media Contacts 15" option signal has been received. The next display will indicate which of the four possible functions was set.
FORCED UPS SHUTDOWN
AUXILIARY CONTROL
The UPS has received a forced shutdown command. This corresponds to an auxiliary control signal received via a "Media Contacts 15" option set for this function.
PROTECT.UPS SHUTDOWN
AUXILIARY CONTROL
The UPS has received a shutdown command. This command will only be executed if load transfer conditions on Mains 2 are satisfied. This corresponds to an auxiliary signal received via a "Media Contacts 15" option set for this function.
FREQUENCY REVERSAL AUXILIARY CONTROL
The UPS has received a command to change its output frequency (50 or 60Hz).
This command is only executed if the inverter is off. The frequency will be changed the next time the inverter is started. The command corresponds to an auxiliary control signal received via a "Media Contacts 15" option set for this function
.
I LOAD > IN
CHECK LOAD | A |
The power drawn by the load is greater than the rated value. The blinking "A" at the end of the message is a prompt to read the load current measurement.
TRANSFER FAULT
CALL SUPPORT DEPT.!
A fault has occurred in the static switch which ensures transfer of the load between the inverter and Mains 2. Servicing by the
PHASE OUT OF LIMITS
!
For a
For a parallel UPS, the phase shift between this inverter and the other inverters is outside tolerances, and the corresponding UPSs has therefore been disconnected.
MAINS 2 SWITCH
Q4S OPEN | ! |
Mains 2 input switch Q4S is open, i.e. transfer of the load from the inverter is impossible.
OUTPUT SWITCH
Q5N OPEN | ! |
MAINT. BYPASS SWITCH
Q3BP CLOSED | ! |
Maintenance bypass switch Q3BP is closed. The system is in maintenance configuration and the load is supplied by Mains 2.
EMERGENCY OFF
OVERLOAD > IN | ! |
The load is no longer supplied by Mains 2 following an extended overload.
BATTERY
CHARGING!
The battery is currently being recharged.
INDEPENDENT
INVERTER FREQUENCY!
The inverter frequency is stable and accurate to 0.05Hz, but no longer synchronous with that of Mains 2.
NUMBER OF INVERTERS
READY INSUFFICIENT!
This message is valid only for parallel UPS systems. The number of UPSs ready for connection to the load is insufficient for the required power level. Another UPS must be started before all the lines together may supply the load. Until another line is started, the load will remain supplied by Mains 2.
BATTERY MAINTENANCE
CALL
Indicates that the battery has probably reached the end of its service life (based on the estimated average service life since its installation).
TRANSFER DISABLED
AUXILIARY CONTROL
Transfer of the load to Mains 2 is inhibited due to:
