A thorough understanding of all the controls and indicators will assure the proper operation of the Battery Charger. This section discusses the front panel indicators and controls.
AC ON: This LED (light emitting diode) indicates that the primary AC power is available to the rectifier/charger.
EQUALIZE TIMER: This timer allows the charger to operate at the equalize level for the preset time, then switch back the "FLOAT" level.
FLOAT ADJUST: This potentiometer adjusts the float level.
EQUALIZE ADJUST: This potentiometer adjusts the equalize level.
AC INPUT: This breaker supplies and protects the AC input line. This device also acts as the unit on off switch.
AC FAILURE: If this led is on, the input AC voltage has failed and the charger will not be able to supply output voltage and current.
HIGH DC: The output of the charger is above the overvoltage level. Shut down one charger at a time to determine which is causing the problem.
LOW DC: If these contacts and/or LED operated, this indicates that the batteries are nearly discharged.
POSITIVE GROUND DETECT: This LED indicates that there is a ground fault on the positive DC bus.
NEGATIVE GROUND DETECT: This LED indicates that there is a ground fault on the negative DC bus.
HIGH AC: If this LED is on the input AC voltage is high. The charger should be shut down to prevent damage.
DC OUTPUT: This breaker supplies and protects the DC output line.
METERS: The meters include Output DC volts and amps.
