LED Indicators
There are two LED indicators on the front of the unit; Battery Charge Status and Battery
Test Status. The functions of these indicators are as follows:
Battery Charge Status:
Constant Green – Fully Charged
Flashing Green – Charging
Constant Red – On Battery
Fast Flash Red – Adjust rectifier
Battery Test Status:
Constant Green – Battery Good
Fast Flash Red – Wait, Then Test
Slow Flash Red – Replace Battery
Manual Battery Test Switch – Push to Test
NOTE
: The Manual Battery Test Switch is
disabled when the battery is charging. Also,
to prevent unnecessary battery discharge, the
Manual Battery Test is disabled for 5 minutes
following a Battery Test. In both cases, the
Wait, Then Test
indication is displayed.
Low Voltage Disconnect Function
The low voltage disconnect function will disconnect the battery when the battery voltage
drops below a 21 Vdc. This is done to prevent deep discharge of the batteries, which can
adversely affect battery life. Both internal and external batteries are disconnected.
External Connectors
AC power is connected via a standard IEC connector located on the left side wall.
The mating connector should be an IEC female connector three-conductor power
cord.
External Batteries are connected through a two pin locking connector. Two of these
connectors are located on the right side wall.
