Overview
This screen gives a general overview of common chill-
er parameters for both shells.
Display Only
Compressor 1
Discharge Temperature
Displays the temperature of the refrigerant in its gas-
eous state at discharge of the compressor #1 as it trav-
els to the condenser.
Oil Pressure
Displays the pressure differential between the Pump
oil pressure transducer (output of oil filter) for com-
pressor #1 and the Sump oil pressure transducer. The
displayed value includes offset pressure derived from
auto-zeroing during the system prelube. If either of the
transducers used to calculate this differential is out of
range, the display will show XX.X.
% Full Load Amps
Displays the percentage of compressor motor #1 full
load amps being utilized by compressor #1 motor.

Compressor 2
Discharge Temperature
Displays the temperature of the refrigerant in its gas-
eous state at discharge of the compressor #2 as it trav-
els to the condenser.
Oil Pressure
Displays the pressure differential between the Pump
oil pressure transducer (output of oil filter) for com-
pressor #2 and the Sump oil pressure transducer. The
displayed value includes offset pressure derived from
auto-zeroing during the system prelube. If either of the
transducers used to calculate this differential is out of
range, the display will show XX.X.
% Full Load Amps
Displays the percentage of compressor #2 full load
amps being utilized by compressor #2 motor.
Chilled Liquid Temperature - Leaving
Displays the temperature of the liquid as it leaves the
evaporator.
