BCM12 Battery Charge Manager

Monitors the state of charge of a battery bank to activate the charging system to ensure full recharging. Can trigger any type of charging system including line chargers and engine-generators. Operates on both 12 and 24V battery bank systems.

The high and low set points to begin and end the charging cycle are adjustable within a range of values.

When installing a Battery Charge Monitor (BCM-12) for the operation of the auto start feature on generators, the parameters of the potentiometers must be adjusted to the following:

Max run timer2.34 vdc4 hours
Low set point2.2 vdc12.2 vdc
High set point4.0 vdc14.0 vdc
Dip Switch Setting (delay on time) 2 Minuets
1 2 3 4 5 6 7 8
ON off ON off off off off off

Upon installation of the updated Dyna-Gen module, a distinction must be made of the type engine used in the generator.

The updated module has a preheat default setting of 8 seconds. This is accomplished by a small black jumper that makes a loop out of the potting on the module board. By leaving this wire intact, the unit will automatically set preheat to 8 seconds. Clipping this loop will double the time to 16 seconds.

Settings are as follows:

  1. Isuzu engines are to be left at the default setting of 8 seconds.
  2. Kubota engines are to be set at 16 seconds by clipping the loop.
