BATTERY EQUALIZER OWNER’S MANUAL
5
of the Battery Equalizer, Battery A will supply the extra current to the load. The Battery Equalizer will then
replenish the energy to Battery A after the surge has passed.
The
VoltMaster
Battery Equalizer is a completely automatic device that requires no human intervention
when installed according to the recommended procedures. Family 1 Equalizers and some Family 2
Equalizers have a manually resetable circuit breaker. If the circuit breaker trips, due to a system overload
or abnormality, it can be reset by pushing the white button. Note that on some units the white circuit
breaker button may protrude slightly in its normal (non-tripped) position. A blown fuse on Family 2
Equalizers requires factory repair. There are no user operational devices on Family 3, Family 4 or Family
5 models.
The following scenarios describe the
VoltMaster
Battery Equalizer' s system operation.
Scenario #1 - 24 volt load present, no 12 volt load present.
The system operates as a system would
without the Battery Equalizer whether the alternator is ON or OFF. The Battery Equalizer is in the
standby mode except for making small adjustments to keep the batteries in balance.
Scenario #2 - Both 24 volt and 12 volt loads present, alternator is OFF.
The Battery Equalizer will
insure that both batteries will discharge at the same rate even if different loads are present.
Scenario # 3 - Both 24 volt and 12 volt loads present, alternator is ON.
The alternator provides 24
volt power to the battery system and to the 24 volt loads. The Battery Equalizer transfers power from the
24 volt source to the 12 volt load by converting 24 volt power to 12 volts. It will supply sufficient 12 volt
power to satisfy the 12 volt load and to maintain battery voltage balance.
