PARALLELING PROCEDURE
(With Load Sharing Circuitry)
Chargers with load sharing circuitry will force both units to share equally. When this circuit is used, each charger control
senses the buss voltage. If the setting on one control has a slightly lower voltage setting, the charger will attempt to put
out more current The sharing circuitry, however, forces the same current through both reactor control coils, forcing both
units to put out the same current. One control can therefore, assume the control of both units. This has the advantage of
both units operating even though one control circuit is open circuited or shorted Connect terminals 1W of each unit
together.
Paralleling procedure is as follows:
1.
Parallel the chargers in accordance with the paralleling procedure instruction sheet without the
paralleling circuit.
2.
Connect the paralleling circuit by turning the paralleling switch of both chargers "on."
3. When the paralleling circuit is used, the units should be checked periodically to make certain both
units are operating and paralleling without the paralleling circuit To check simply turn the paralleling
switch to "off" to disconnect the circuit.
