Oil Pump 1 And 2 Screen - York YD Mod D Operation Manual

Oil pump 1 and 2 screen

Figure 26: Oil pump 1 screen
This screen displays the chiller oil sump along with the compressor oil cooler. All of the setpoints
for compressor Variable Speed Drive Oil Pump are maintained here. The oil pump can be manually
controlled from here. The screen is identical for oil pumps 1 and 2.

Description
Lights when the associated compressor Variable Speed Oil Pump Drive is being
commanded to run. Otherwise, it is off.
Displays the pressure differential between the associated Pump oil pressure (HOP)
transducer and the common Sump oil pressure (LOP) transducer. If this compressor
is the lead compressor, includes offset pressure derived from auto-zeroing during
the compressor pre-lube of the lead compressor. However, if compressor #2 is the
lead compressor, this value includes offset pressure derived from auto-zeroing during
compressor #2 Pre-lube (refer to auto-zeroing explanation under the Compressor
Screen). If either transducer used to calculate this differential is out of range, the
display field will show XX.X.
Displays the high-side oil pressure measured at the compressor bearing input.
Displays the speed command that is being applied to the compressor Oil Pump
Variable Speed Drive.
Displays the oil pressure setpoint that Variable Speed Oil Pump is controlling to.
During the pre-lube and for the first 15 seconds of System Run, this is the target
Setpoint, and is fixed at 45.0 psid. For the remainder of compressor run, it is the
programmed Setpoint Oil Pressure.
If a Standby Lubrication is in progress on compressor #1, displays the time remaining
in the 2 minute operation.
If compressor #1 is not running, displays the time remaining until the next Standby
Lubrication.
Displays the time remaining until the user programmed Setpoint Oil Pressure is used.
While this clock is decrementing, the Target Oil Pressure Setpoint (fixed at 45.0 psid) is
in effect.
