V. AUX OUTPUT

The output terminal strip provides an additional output to accomodate 12 volt accessories, such

as: Kussmaul’s 12Vdc air pump. The AUX output works in conjunction with a front panel mounted

rocker switch. For normal operation, the rocker switch should be left in AC mode, which means that

the aux accessory works only when shoreline power is supplied to the charger. With the switch in

DC mode the aux accessory will operate when AC power is ON or OFF. In either position the aux

output operates from the vehicle’s batteries, while the charger automatically recharges the batteries

as required.

VI. AUX OUTPUT AUTOMATIC RESET FUSE

The LPC 40 contains an internal automatic reset fuse. Should the AUX output fuse open, reset the

fuse by cycling the AC input power (shoreline).

VII. LED STATUS INDICATORS

1. AUX ON: Indicates that power to the AUX output terminal is ON.

2. AC ON: Indicates that AC input voltage is present. Note: Battery must be above 9Vdc and of

proper polarity.

3. BATTERY OK: Indicates a battery of proper polarity is connected to the charger output terminals.

VIII. COOLING FAN

The LPC 40 is fan cooled and automatically adjusts circulation depending on the current output and

internal component temperature. Air is circulated from the rear panel fan and exhusted through the

front panel. When the load current increases or the internal component temperature increases, the

fan speed increases to allow greater air movement through the unit.

OPERATION

I. BATTERY CHARGER OUTPUT

1. A discharged battery is recharged to roughly 90% or until the current tapers down to less than 4

amps. From current-limit (40 amps) to 4 amps, the LPC 40 output terminal is voltage regulated

at the boost voltage level.

2. Once the current decreases to less than 4 amps, or the 1-hour boost voltage timer times-out, the

output terminal is set to float voltage level.

NOTE: See specifications for battery selector switch boost and float voltage settings.
