If the Motor Rotation Is Not Clockwise (as viewed through the sight glass), reverse any
2 of the 3 incoming power le ads t o the starter and recheck r ot ation.
Note: Solid-state start ers have phase protec tion and will not allo w a start if the phase is not cor-
rect. Instead, a Start er Fault message will occ ur if this happens.
Notes on Solid-State Starters (B enshaw, Inc.)
1. When the compressor is energized to start by th e 1CR relay, confirm that th e Relay On LED
is lit on the starter SCR control board. The compressor motor should start to turn
immediately when th is lig ht comes on. If not, adju s t t he s t art torque potentiome ter in a
clockwise direction.
2. Observe that all 6-ga te LEDs are lit on the starter SCR control board.
CAUTION CAUTION
!
Do not check motor rotatio n during coastdown. Rota t io n ma y have reversed dur-
ing equalization of ve sse l pressures.
