5.5 Other Features
5.5.1 Shutdown
'Remote shutdown': Using communication capabilities, the computer can direct the UPS to turn itself off
following controlled shutdown of the system. Subsequently the UPS will remain off for at least a few seconds
(see also 6.1). LED 'operation' will blink green. The unit will start up again as soon as the utility returns.
'No-load shutdown': The UPS will also switch off if the load is < 2% of the maximum load, and the input is
absent for more than 10 minutes. For more information see section 5.3.2, message 'SHUTDOWN ALARM'.
NOTE: If the UPS operates in parallel, the no-load function is not available.
'Emergency shutdown': for more information see section 5.3.2, message 'IMMEDIATE SHUTDOWN'.
5.5.2 Utility start
The UPS is able to start, even if the batteries are not connected. Alarm messages 'BATTERY FUSE FAILURE'
and 'BATTERY DEPLETED' will be shown. The run time is zero.
5.5.3 Sleep and wake-up
GE Digital Energy™ UPS monitoring software allows you to program a 'sleep period' of the UPS by sending
two commands to the UPS:
- shut down after # minutes, and subsequently:
- shut down during # hours.
After the first command the following screen appears:
During the sleep period the output voltage is no longer available. LED
'operation' blinks green, and the LCD screen shows the time left until
restart:
If a utility failure occurs during the sleep period and the battery voltage
eventually drops below 200Vdc, the UPS will automatically switch off in
order to save battery power. When the main returns the UPS will start up
automatically. The programmed sleep time however is lost.
The sleep period can be cancelled by either turning the UPS ON/OFF switch (6) off for a few seconds or by
sending the appropriate command via the RS232/SNMP port.
5.5.4 Overload protection in bypass mode
The UPS will protect itself in case of overload. Upon an overload which is caused by abnormal circumstances
the UPS will switch to bypass operation, and subsequently the bypass input fuse on the front panel will trip. The
capacity of the bypass fuse allows it to handle the inrush currents of the equipment connected to the UPS. The
fuse will only trip after more than an hour at an input current of 40Amp (LP 5/6-11U) or 50Amp(LP8-11U) or
63Amp (LP 10-11U).
In order to protect the UPS system the software will cut off the abnormal current:
in 10 minutes: in 1 minute:
LP 5/6-11U: 36Amp 49Amp
LP 8-11U: 55Amp 65Amp
LP 10-11U 70Amp 81Amp
Between 36-49Amp(LP 5/6-11U), 55-65Amp (LP 8-11U), 70-81Amp(LP 10-11U) the time is inversely
proportional to the input current. We advise to place a distribution fuse slow blow type between UPS input and
the utility supply. Please refer to the installation drawing.
