Operation
B. Safety Setpoints
A detailed explanation of all safety setpoints can be found
in the Compact Logix PLC manual, p/n 35391CL.
1. Oil Pressure
Low oil pressure differential stops the compressor unit
when there is an insufficient difference in pressure
between the oil manifold and suction.
2. Discharge Pressure
High discharge pressure cutout stops the compressor
unit, when the discharge pressure in the oil separator
exceeds the setpoint.
3. Suction Pressure
Low suction pressure cutout stops the compressor
unit when the suction pressure drops below the
setpoint.
4. Oil Filter Differential
High oil filter differential cutout stops the compres-
sor unit when the difference between the outlet and
inlet of the filter exceeds the setpoint.
5. Oil Temperature
The oil temperature cutout stops the compressor
unit when the oil temperature is too high or too low.
6. Discharge Temperature
The high discharge temperature cutout stops the
compressor unit when the discharge temperature
exceeds the setpoint.
