RAM DBS II

Refrigeration Solid State Starter

ALARM CONDITION

Current Unbalance

SOLUTION

Check for voltage balance between
phases. Customer must consult power
supplier if balance is abnormal.

Compare current reading on DBS display
to reading of clamp-on ammeter for
accuracy.

Load balance on customer's system
must be re-distributed.

Adjust current unbalance and current run
delay setpoints. See Table 13, Section 9.

Replace DBS control board.

POSSIBLE CAUSE

Current between two phases
exceeds the setpoint value longer
than the time delay setpoint.

Electrical loads on power supply
not distributed equally among
phases.

DBS setpoints not set correctly or
according to actual conditions.

Abnormal SCR operation due to
defective DBS control board.
