    50/60 HZ (Export) Introduction The MAC SCR series of battery chargers were designed especially for lead acid batteries used in demanding deep cycle applications. Its overall simplicity, method of operation and trouble-free performance makes the SCR charger attractive to every type of equipment user. To operate, after the charger is connected to AC power, the user simply plugs the DC cord into the battery to activate the unit.
  • Page 4 Do not operate this charger with an extension cord. Locate cord so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress. Do not operate this charger if it has been subject to abuse, damage or improper maintenance. Provide adequate ventilation for the batteries and charger.

  • Page 5: Pre-Operating Procedure

    CAUTION - The dual AC input charger may be equipped with an AC voltage select switch located on the front of the unit which will allow you to connect the charger to one of two AC supply voltages. You must be absolutely sure that the switch matches the supply voltage to which the charger will be connected.

    1. The DC charging receptacle does not grip the DC output plug tightly, is loose or does not make a good electrical connection. 2. The DC output plug and/or charging receptacle feel hotter than normal. 3. The DC output plug pins or receptacle contacts are bent, corroded or are dark or bluish in appearance.

    3] CONSTANT FINISH CURRENT - To fully charge the batteries while avoiding damage to the batteries, a lower constant current is delivered to the batteries. Charge is terminated when battery is fully charged. During the charging process, the rate of voltage rise over time is constantly monitored.

    CAUTION Improper profile setting may damage the batteries. To change setting remove cover and follow instructions in charger. 7. When batteries are fully charged, only the Green LED "Charge Complete" should be illuminated. WARNING Do not disconnect the DC output cord from the battery receptacle when the charger is on.

    This feature was developed to maintain batteries in a charged state while they are left in storage. FCS will be found on most MAC SCR Domestic chargers. This feature is not incorporated into the Export Dual AC Voltage models. The FCS feature will be activated upon satisfaction of the following four conditions: 1.

    To verify that your charger has the FCS feature, simply connect the DC output to the battery without plugging in the AC. The LED’s on the front of the charger will flash through the self- diagnostic sequence if the unit has FCS. 8.
  • Page 11 GENERAL SERVICE PROCEDURES Refer to quick check guide first before working on charger or removing cover. The obvious is often missed. If unable to diagnose from quick check, unplug AC and DC connectors, and remove cover. Carefully inspect for damaged, discolored components and loose or discolored wiring. If unable to spot problem, proceed to DC Circuit Checkout Procedure.
