BATTERY PANEL 5
INTRODUCTION
GENERAL DESCRIPTION
The Battery Panel is used for monitoring the accumulator battery of
thereservesupplyarrangementfortheradioinstallations.Batteryvolt-
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 BatteryPanel is intended for installations withone or two batteries
(determinedbyinternaljumper setting)andoneortwobattery 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.
