Dry Run to Test Start-Up Sequence
1. Disengage the main motor disconnect on the starter front panel. This should only
disconnect the motor power. Power to the controls, oil pump, and starter control circuit
should still be energized.
2. Look at the default screen on the LID: the Status message in the upper left-hand corner will
show a ‘‘Manually Stopped’’ message. Press CCN or Local to start. If not, go to the
Schedule screen and override the schedule or change the occupied time. Press the LOCAL
softkey to begin the start-up sequences.
3. Check that chilled water and condenser water pumps energize.
4. Check that the oil pump starts and pressurizes the lubrication system. After the oil pump
has run about 15 seconds, the starter will be energized and go through its start-up
sequence.
5. Check the main contactor for proper operation.
6. The PIC will eventually show an alarm for motor amps not sensed. Reset this alarm and
continue with the initial start-up.
