SECTION 2 – OPTIVIEW CONTROL CENTER
FIGURE 25 - OIL PUMP 1 SCREEN
This screen displays the chiller oil sump along with
the compressor oil cooler. All of the setpoints for com-
pressor Variable Speed Drive Oil Pump are maintained
here. The oil pump can be manually controlled from
here. The screen is identical for oils pumps 1 and 2.
DISPLAY ONLY
Oil Pump Run Output (LED)
Illuminated when the associated compressor Variable
Speed Oil Pump Drive is being commanded to run.
Otherwise, it is extinguished.
Oil Pressure
Displays the pressure differential between the associ-
ated Pump oil pressure (HOP) transducer and the com-
mon Sump oil pressure (LOP) transducer. If this com-
pressor 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.

OIL PUMP 1 AND 2 SCREEN
Pump Oil Pressure (HOP)
Displays the high side oil pressure measured at the
compressor bearing input.
Oil Pump Drive Command Frequency
Displays the speed command that is being applied to
the compressor Oil Pump Variable Speed Drive.
Setpoint or Target Oil Pressure
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.
Oil Seal Lubrication Time Remaining
If a Standby Lubrication is in progress on compressor
#1, displays the time remaining in the 2-minute opera-
tion.
Next Oil Seal Lubrication
If compressor #1 is not running, displays the time re-
maining until the next Standby Lubrication.
