50 AMP BATTERY CHARGER DIAGNOSTICS
The Chargemaster 50 is protected against overload, short
circuits, over heating and under and over voltage. If a
fault condition occurs, a load bar segment on the display
illuminates red. The LED position indicates the failure
cause as:
1. Wrong AC voltage. Never connect to three phase
current.
2. Charger failure; Power button blinks.
3. Battery voltage too high
4. Internal temperature too high
5. Battery low or short circuit. The battery bank should
blink indicating source of problem.
The Chargemaster 50 is not protected against reversing
polarity of the DC-output or 3 phase AC on the AC-input.
Note to monitor the battery temperature sensor. The
charge voltages are automatically adjusted for changing
temperatures. When the battery temperature is high, the
charge voltage goes down. When the battery temperature is
low, the charge voltage goes up. This prevents overcharging
and gassing which in turn will extend battery life.
Note that if there are battery charger problems the fi rst
things to check for are loose connections and/or burnt
wiring. Refer to the connection compartment terminal
illustration.
