Check Oil Pressure and Compressor Stop
1. When the motor is up to ful l s pee d, note the differenti al oi l pressure reading on th e LID
default screen. It sho uld be between 18 and 30 psid (12 4 to 206 kPad).
2. Press the Stop button and listen for any unusua l sounds from the compresso r as it coasts to
a stop.
Calibrate Motor Current Demand Setting
1. Make sure that the compressor motor rated load amps in the Service1 screen has been
configured. Place an ammeter on the line that pass e s through the motor load cu r r ent
transfer on t he motor side of the power fa ctor correction ca pacitors (if pr ovided).
2. Start the compresso r and es t ablish a steady motor c ur r en t value between 70% and 100 %
CAUTION CAUTION

Do not check motor rotatio n during coastdown. Rotat io n may have reversed dur-
ing equalization of vessel pressures.
