SECTION 2 – OPTIVIEW CONTROL CENTER
Setpoint or Target Oil Pressure
Displays the oil pressure setpoint that compressor #1
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 #1 run, it is the pro-
grammed Setpoint Oil Pressure.
Pulldown Time Remaining
Displays the time remaining until the user programmed
Setpoint Oil Pressure is used. While this clock is dec-
rementing, the Target Oil Pressure Setpoint (fixed at
45.0 PSID) is in effect.
Oil Pump 2
Oil Pump Run Output (LED)
Illuminates when compressor #2 Variable Speed Oil
Pump is being commanded to run.
Pump Oil Pressure (HOP)
Displays the high side oil pressure measured at the
compressor #2 bearing input.
Oil Pressure
Displays the pressure differential between the Pump
oil pressure (HOP) transducer for compressor #2 and
the common Sump oil pressure (LOP) transducer. If
this compressor is the lead compressor, includes offset
pressure derived from auto-zeroing during compres-
sor #2 Pre-lube. However, if compressor #1 is the lead
compressor, this value includes offset pressure derived
from auto-zeroing during compressor #1 Pre-lube (re-
fer to auto-zeroing explanation under the Compressor
Screen). If either transducer used to calculate this dif-
ferential is out of range, the display field will show
XX.X.
Oil Pump Drive Command Frequency
Displays the speed command applied to compressor #2
Variable Speed Oil Pump.
Setpoint or Target Oil Pressure
Displays the oil pressure that compressor #2 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 re-
mainder of compressor #2 run, it is the programmed
Setpoint Oil Pressure.
Pulldown Time Remaining
Displays the time remaining until the user programmed
Setpoint Oil Pressure is used. While this clock is decre-
menting, the Target Oil Pressure Setpoint (fixed at 45.0
PSID) is in effect.
Oil Level (bar graph)
(Software version C.MLM.11.02.xxx (and later) or
C.OPT.11.02.300 (and later))
Displays the oil level in the oil sump as a vertical
graph. The range of the graph is 0% to 100%. Three
colors are used as follows: 0% to 35% - red; >35% to
80% - green; >80% to 100% - yellow. Only displayed
if enabled using the Oil Level Detection (Enable/Dis-
able) key.
Programmable
Oil Level Detection (Enable/Disable)
(Software version C.MLM.11.02.xxx (and later) or
C.OPT.11.02.300 (and later))
Access Level Required:
SERVICE
Allows the user to enable or disable the Oil Level De-
tection feature. When enabled, displays the oil level in
the oil sump as a vertical graph.
