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)
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)
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.
NAVIGATION
Home
Access Level Required: VIEW
