4: Single Module Operating Procedures
4.1.2 Start-up on battery mode (cold start)
In the absence of the utility power supply, the UPS can be started from its internal batteries – sometimes referred to as a
“cold start”. This is only possible if the batteries are well charged.
Read through this procedure before you attempt to carry it out. In a part of this procedure you have to press the ON button
twice within a 15 second period. If you take longer than this, the UPS will not start and you will have to turn it
OFF,
by
pressing the
OFF
button, before you can make another attempt to start it.
1. Hold the
ON
button for approximately 5 seconds until a double beep is heard
then momentarily (within 15
seconds) release the button and press it again
for approximately 3 seconds until a further beep is heard.
During the first button press
a) The UPS fans will start.
b) The UPS control system will boot-up and initially turn on all the leds and
LCD symbols for a few seconds.
c) When control system boot-up has completed, all the leds will turn off,
the LCD mimic will display the UPS connected to the battery and the
UPS status will be shown as
off
.
Following the second button press
a) The LCD display will initially keep the UPS
off
screen displayed for a
few seconds and will then run a self-test routine for several seconds,
during which time the LCD screen will show the input voltage (
r 0
V
).
b) The audible alarm will sound intermittently but may be silenced by
pressing the alarm silence (
ON
) button.
c) If the UPS passes its self test routine it will turn on the inverter and begin
to provide output power. The LCD mimic display will show that the UPS
is operating ‘on battery’ mode.
2. Check all metered parameters to ascertain that the battery voltage and UPS
output indications are correct (see page 40)
CAUTION: If you start the UPS using battery power, the battery will begin to discharge and will only provide
output power for a short time (depending on load) unless the UPS utility input supply is restored. This facility is
primarily intended to be used when testing the UPS.
