BATTERY PANEL
5
INTRODUCTION
GENERAL DESCRIPTION
The Battery Panel is used for monitoring the accumulator battery of
the reserve supply arrangement for the radio installations. Battery volt-
age and current are displayed on digital panel meters, and visual and
audible alarms are incorporated for warning of high/low battery volt-
age and failure of AC supply.
The
Battery Panel is intended for installations with one or two batteries
(determined by internal jumper setting) and one or two battery chargers.
It contains separate alarm lamps for indication of high/low battery volt-
age for each battery, and separate alarm lamps for indication of AC
supply failure for each battery charger. With a push button switch it is
possible to switch the panel meters between monitoring battery 1 and
battery 2 in two battery installations.
The Battery Panel include dimmer, mute and test functions. The dis-
plays and keyboard are backlight illuminated.
The Battery Panel must be connected to a DC supply voltage of 21.6V
to 31.2V, normally the + 24V DC from the AC Power Supply/Charger.
In installations with two AC Power Supply/Chargers, the Battery Panel
contains an automatic switch which secures supply voltage as long as
just one of the AC Power Supply/Chargers are operating.
For current measurements the Battery Panel should be connected to
the AC Power Supply/Charger
or Junction Box Shunt containing fuses
and a shunt resistor.
