    6 section iii troubleshooting 1. Caution notice before troubleshooting, always isolate and de-energize the charger by opening the ac circuit breaker (cb1) and the dc circuit breaker (cb2). This avoids the possibility of high short circuit current damaging the charger, tools, test equipment, or injur...

    11 section iv system adjustments 1. Voltage adjustments and response when abnormal output voltage exists (or no output current is present), and the previous checks in table a on page 27 “voltage adjust ineffective” have been made without locating the fault, switch the ac breaker (cb1) to off. Switch...

  • Page 16

    12 b. Equalize adjustment 1. Since the equalize adjustment will not affect the float voltage adjustment and requires a higher voltage it should always be made after the float voltage is determined. Use a portable voltmeter of one percent accuracy as in the float adjustment. Set switch (sw1) to “equa...

    16 if it is necessary to adjust the lva threshold in the field, the user must load the battery bank and allow the battery voltage to drop while decreasing the float voltage adjustment to the desired cut-off potential. The lva potentiometer is then adjusted so that the lva relay is activated into the...

  • Page 21

    17 7. Equalize timers purpose: equalize timers are used to switch the charger into equalize charging mode for a set period of time, when required by the batteries. "float" and "equalize" indicating lights mounted on the instrument panel can be included with all timers to indicate the charging mode. ...
