Controls, connectors and
indicators
3.1.1
Front panel indicators
See figure 3.1 for an overview of the indicators on the
battery charger:
1 Charger status - Shows the mode of the charger:
On, Bulk, Full, Float (see section 2.1).
2 Mains LED - The power LED is green if the battery
charger is connected to the mains and switched on.
The LED is yellow if there is a mains fault.
3 Fault - General fault shows as yellow.
4 Battery - The LED is green when the battery
charger is connected to the battery. The LED is
yellow when there is a battery fault: the battery is not
connected, or the total battery voltage is either lower
than 16 V or higher than 32 V.
5 Current limit - the LED shows yellow and closes
the output when:
•
the output current of the battery is above 70 A.
•
the auxiliary output is greater than 5 A.
6 Battery in use - Shows when the net current from
the battery to the system (load) is greater than 1 A.
7 Over temp/Sensor Fault - The LED is yellow
when the temperature sensor connected to the
battery is greater than 60 ºC. Sensor Fault shows
when the sensor is not connected and the
temperature switch of the temperature sensor is on.
8 Voltage display - Shows the voltage of the battery.
9 Current display - The LCD display shows the
charge current to the battery (positive value), and the
delivered current when the battery gives output
(negative value).

Rear panel connections
See figure 3.2 for an overview of the rear panel of the
battery charger:
10 Out -/+ - Power out connector to the 24 VDC 70 A
limit output back-up power for the Voice Alarm
System.
11 In +/- - Power connector to the battery.
12 Temperature sensor - Connector for the
temperature sensor of the battery.
13 Slide switch - ON/OFF selector for the
temperature sensor.
14 ON/OFF Switch - Connects and disconnects the
mains power supply.
15 Mains power inlet - A socket for connecting the
battery charger to the mains power. Mains voltage of
100 - 240V ± 10% is accepted
16 Battery Capacity - Adjustor for selecting the
charging current of the battery.
17 Trigger Outputs - Give a fault trigger output if a
fault occurs on: Mains, Battery, Battery in Use,
General Fault. All fault relays have normally closed
and normally open contacts (SPDT), and by default
are normally energized (i.e. are fail safe).
18 24VDC for volume override - 24 VDC 3 A
output back-up power for the volume override.
19 RCP - 2 x 24 VDC 3A output back-up power for the
Remote Control Panel (RPC1 and RCP2), 5 A in
total for RCPs and volume override.
