Operating the RIP
a)
When mains power is on, the LEDs POWER, 24 V, and CHARGE are lit while RIP
sounder remains in silence.
Note:
If the batteries are charged (the battery voltage exceeds 26 V) then the
CHARGE LED is off.
b)
After applying mains power to the RIP its batteries are tested. If no batteries are
connected (or are out-of-service, or battery voltage is below 20 volt) then the sounder and
the CHARGE indicator turn on in interrupted mode for 8-10 seconds. After that the sounder
is hushed, but CHARGE indicator flashes until batteries are connected. Battery testing
procedure is carried out periodically (at least once every 8 hours). If no batteries are found,
then CHARGE indicator flashes again.
c)
In the events of a short load circuit failure or a prohibitive output overload (in AC
line operating mode), after 3 s the RIP turns on in the interrupted mode with the interval of
1 -2 second until the trouble disappears. The 24 V and CHARGE indicators are off. The
POWER indicator and the sounder turn on in interrupted mode. After failure’s disappearing
the RIP automatically continues normal operating.
d)
When mains power supply fails the batteries begin to power the load circuit, the 24 V
indicator being turned on and the sounder going off periodically. The POWER and
CHARGE indicators are off.
e)
If the voltage of the batteries has dropped to 22 V the sounder switches on and off
five to ten times more rapidly. It is necessary to take measures to restore mains power line as
soon as possible.
f)
If the voltage of the batteries has dropped below 20 V, then, to avoid deep discharge
of the batteries, the batteries are shut off from the load. In such case the POWER and 24 V
indicators are off, the CHARGE indicator is flashing, and audible alarm is sounding within
two first hours. In 2 hours the RIP will be transferred to low battery powering mode, with
the CHARGE indicator and sounder turning on once every 10 seconds.
If the AC power is expected to be not available for more than 7 days, then, to avoid an
overdischarge of the batteries, disconnect them from the RIP board.
Performance of LED indicators and the sounder as well as actions of the staff depending
on various circumstances are shown in Table 1.
