screen allows manual control of the frequency command
sent to the VSOP.

Oil Pressure
Displays the pressure differential between the high side
oil pressure transducer (output of oil filter) and the low
side oil pressure transducer (compressor housing). The
displayed value includes offset pressure derived from
auto-zeroing during the system prelube. (Refer to expla-
nation of auto-zeroing under the Compressor screen). If
either of the transducers used to calculate this differential
is out of range, the display field will show XX.X.
Oil Sump Temperature
Displays the temperature of the oil in the sump.
Oil – Saturated Condenser Temperature Differential
(Software version C.OPT.01.21.307 and later)
(Variable Speed Oil Pump Only)
Displays the difference between the Oil Sump Tem-
perature and the Saturated Condenser Temperature. This
parameter is useful when analyzing oil heater operation
since it is used in the control of the oil heater.
Sump Oil Pressure (LOP)
Displays the low side Oil Pressure measured at the
sump.
Pump Oil Pressure (HOP)
Displays the high side Oil Pressure measured at the
compressor bearing input.
Oil Pump Run Output (LED)
Indicates whether the Oil Pump is being commanded
to operate.
Oil Return Solenoid (LED)
Indicates whether the solenoid is energized.
Oil Heater (LED – Variable Speed Oil Pump Only)
Indicates whether the oil heater output is energized.
Oil Seal Lubrication Time Remaining
Access Level Required: SERVICE
If a seal lubrication is in progress, this will display the
amount of time remaining in the lubrication process.
Service Technicians refer to YORK Service Manual
160.54-M1.
Next Oil Seal Lubrication
Access Level Required: SERVICE
This display will show the time remaining until the next
seal lubrication when this function is enabled. Service
