7. MAINTENANCE
a. This charger is designed to require a minimum of maintenance. There are no rotating parts except
in the optional timer and all components have a nominally indefinite life with no expected aging effect. It
should be kept clean, dry and checked periodically to make sure all connections are tight. If necessary, dry
air may be used to blow dust out of the interior. In the event of any irregular operation, examine, and tighten
if necessary, all internal and external connections and check circuits for continuity (see schematic diagram
on page 28). If the difficulty cannot be remedied, contact the manufacturer.
8. NORMAL PERFORMANCE
a. Assuming that the charger has been operating in the float position, an indication of normal
performance can be obtained by setting the FLOAT/EQUALIZE switch in the equalize position (turn timer
off zero). Increased charge current will show on charger ammeter until the battery reaches the equalize
voltage. At this point the current should slowly decrease.
b. If the charger has been operating in the equalize voltage position, turn SW1 to FLOAT (turn the
timer manually to zero). The charger will indicate zero or little output current until the float voltage is
reached. At this point, the current should increase slowly to the system load value, (the battery is now
“floating” across the line with approximately equal input and output currents).
c. When operating normally, the current limit control will limit the maximum charger output current
to approximately 110% of the rated charge current. In case of a high DC current demand, the current limit
control will keep the charger output within safe values without tripping the DC circuit breaker or the AC
breaker.
