Electrical Logic

• Enable signal from customer’s machine• Motor starters, 2HP & 3 HP• Turn system on every 5? minutes to circulate oil. If measured

temperature is too high, continue running until cool.• Pressure switch: shut down if pressure drops = leak. Include

time delay after startup so system can pressurize.• Lack of cooling fault: If system doesn’t cool in x period of time

then activate alarm.• Power light• Service disconnect
