gurations:
•
No Pump
– A warning will occur if the Dis-
charge Pressure minus the Oil Pressure is
greater than the Low Compressor Oil Pres-
sure Warning Setpoint for the period of the
delay.
•
Full Time
- A warning will occur if the Oil
Pressure minus the Discharge Pressure is
less than the Low Compressor Oil Pressure
Warning Setpoint for the period of the delay.
•
Demand
- A warning will occur if the Dis-
charge Pressure minus the Oil Pressure is
greater than the Low Compressor Oil Pres-
sure Warning Setpoint for the period of the
delay.
•
Shaft pump or Shaft Aux. Pump
- A warn-
ing will occur if the Oil Pressure minus the
Discharge Pressure is less than the Low
Compressor Oil Pressure Warning Setpoint
for the period of the delay.
Low Comp. Oil Temperature Sensor Fault
- This
shutdown message is issued if the Oil Temperature
reading was to the lower or minimum range (out of
range) for its sensor.
Low Comp. Oil Temperature Shutdown
- The Oil
Temperature was less than or equal to the Low Oil
Temperature Shutdown setpoint for its time delay.
Low Comp. Oil Temperature Warning
- The Oil
Temperature was less than or equal to the Low Oil
Temperature Warning setpoint for its time delay.
Low Demand Pump Pressure Warning
- This warn-
ing will be generated if the selected pump type is
Demand, the compressor is running, the pump is run-
ning, and the oil pressure is less than 5 PSI above the
discharge pressure for 30 seconds.
Low Demand Pump Pressure Shutdown
- This
shutdown is generated if the selected pump type is
Demand, the compressor is running, the pump is run-
ning, and the oil pressure is less than 2 PSI above the
discharge pressure for 120 seconds.
Low Discharge Pressure Shutdown
– The Discharge
Pressure was less than or equal to the Low Discharge
Pressure Shutdown setpoint for its time delay. This
setpoint is checked when enabled, when the com-
pressor is running, and when a programmable com-
pressor start delay has timed out
Low Discharge Pressure Sensor Fault
- This shut-
down message is issued if the Discharge Pressure
reading was to the lower or minimum range (out of
range) for its sensor.
Low Discharge Temperature Sensor Fault
- This
shutdown message is issued if the Discharge Tem-
perature reading was to the lower or minimum range
(out of range) out of range for its sensor.
Low Disch Temp Sensor Warning
- This warn-
ing message is issued if the Discharge Temperature
reading (analog board 1, channel 2) was to the lower
or minimum range (out of range) for its sensor.
Low Economizer Pressure Sensor Warning
- This
warning message is issued if the Economizer Pres-
sure reading (analog board 2, channel 14) was to the
lower or minimum range (out of range) for its sensor.
Low Filter Pressure Sensor Warning
- This warning
message is issued if the Filter Pressure reading (ana-
log board 1, channel 7) was to the lower or minimum
range (out of range) for its sensor.
Low Kw Monitoring Sensor Warning
- This warning
message is issued if the Kilowatt Monitoring read-
ing (analog board 2, channel 16) was to the lower or
minimum range (out of range) for its sensor.
Low Liquid Level Sensor Warning
- This warning
message is issued if the Liquid Level reading was to
the lower or minimum range (out of range) for its
sensor.
Low Main Oil Inj Pressure Sensor Warning
- This
warning message is issued if the Main Oil Injection
Pressure reading was to the lower or minimum range
(out of range) for its sensor.
Low Main Oil Injection Pressure Shutdown
- This
shutdown can occur if Oil Injection was enabled. The
Oil Injection Pressure (channel 15, Analog Board 2)
must be greater than or equal to the Suction Pres-
sure times 1.5, plus the setpoint to be in the safe
condition, otherwise this shutdown will occur. Used
only on vertical oil separator with liquid injection oil
cooled packages.
Low Manifold Pressure Sensor Warning
- This
warning message is issued if the Manifold Pressure
reading was to the lower or minimum range (out of
range) for its sensor.
Low Motor Current Sensor Warning
- This warning
message is issued if the Motor Current reading (ana-
log board 1, channel 16) was to the lower or minimum
range (out of range) for its sensor.
Low Motor Current Shutdown
- This shutdown
message is issued if, while the compressor was run-
ning, the Motor Amps reading was less than or equal
to the Low Motor Amps Shutdown setpoint.
Low Oil Differential 1 (Kobe)
– If the compressor
type is set to Other Manufacturer (Kobe), the oil
pump type is set to Demand and if the differential be-
tween Oil Pressure and Suction Pressure is less than
50 PSI for 5 seconds this shutdown will occur. This
