Battery Controller Board Type 5660A

Battery Controller Board, type 5660A, is shown on assembly
diagram C91799/A. This is an X-channel device which enables
the operating system to monitor the charging process and
remotely shut down the load.
The Battery Controller Board, type 5660A, controls the DC
voltage output of a power converter unit (PL4) between the
range +11.2 V to +15.6 V in order to maintain the integrity of
the +12 V 15 Ah Lead Acid Battery (PL3), over the operating
temperature range (temperature sensor on PL1).
The 5660A has the ability to switch the load (PL6) ON/OFF as
directed by the operator, whilst continuing to charge the
