7. Appendix A - remote commands and alarms card -
Technical support personnel may give the COMMAND and the three ALARMS functions that are different to the
standard configuration of the alarms card (see page 19) .
The options available are listed below:
ALARMS:
- DISTURBANCES ON BYPASS LINE
- MANUAL BYPASS, SWMB ON
- BYPASS LINE VOLT. FAIL OR SWBY, FSCR OFF
- MAIN LINE VOLTAGE FAIL OR SWIN OFF
- PREALARM, LOW BATTERY VOLTAGE
- LOW BATTERY CHARGE OR CLOSE SWB
- LOW INPUT VOLTAGE OR OUTPUT OVERLOAD [W]
- OUTPUT OVERLOAD
- BYPASS FOR OUTPUT POWER “VA” < AUTO-OFF VALUE
- INTERNAL FAULT: number
- TEMPORARY BY-PASS, WAIT
- BYPASS FOR OUTPUT OVERLOAD
- BYPASS COMMAND ACTIVE; 8=COM. OFF
- REMOTE BYPASS COMMAND ACTIVE 8=OFF
- OVERTEMPERATURE or FAN FAILURE
- INPUT VOLTAGE SEQUENCE NOT OK
- OUTPUT OFF, CLOSE SWOUT OR SWMB
- BLOCK COMMAND ACTIVE; 8=OFF
- REMOTE BLOCKING COMMAND: ACTIVE 8=OFF
- MEMORY CHANGED: CODE = number
- AUTO-OFF Timer: Toff= 0: 0', Ton= 0: 0'
See the section on “alarm messages” on “Display and control panel” manual, for an explanation of the alarms.
COMMAND:
name description Typical application
Battery charge inhibition
Disables the recharging of the battery,
keeping the recharge current to a
minimum, independently of the load.
This is done with the contact kept
closed; if reopened, the command is
cancelled.
When there is a generator, this
allows its output power to be used
only to supply the load and not
also to recharge the battery.
Inhibition of synchronization
with backup mains
Disables the use of the by-pass line and
the synchronization of the inverter. In
the event of an overload or fault, the
UPS blocks and the load remains
unpowered.
This is done with the contact kept
closed; if reopened, the command is
cancelled.
To be used when the frequency of
the generator or of the backup
mains is highly unstable and it is
thus preferred to inhibit the
synchronization of the inverter.
Battery disconnector contact
Activates the battery discharging or
disconnected alarm.
To be used to indicate the opening of a
battery switch located external to the
UPS.
A closed contact must be provided
when the external switch is opened.
Displays the status of the battery
disconnector.
