The Oil Pressure Transducer for this Chiller
Starter Contactor is reading a pressure either above its
Energized [all Stop Condenser Pressure by 15 Psia or more, or
modes] below its Evaporator Pressure 10 Psia or
more for 30 seconds continuously.
The Evaporator Refrigerant Pressure dropped
below 10 psia just prior to compressor
Chiller Prestart and start. The pressure fell below 10 psia while
Chiller Energized running but before the 3 minute ignore time
had expired or fell below 16 Psia after the
3 minute ignore time had expired.
