High RPM Shutdown
- This shutdown applies if En-
gine or Turbine Drive was enabled. If the RPM’s of the
motor exceeds this setpoint, a shutdown will occur.
High RPM Warning
- This warning applies if Engine
or Turbine Drive was enabled. If the RPM’s of the mo-
tor exceeds this setpoint, a warning will occur.
High Separator Temperature Sensor Fault
– This
shutdown message is issued if the Separator Tem-
perature reading was to the upper or maximum range
(out of range) for its sensor.
High Suction Pressure Shutdown
- The Suction
Pressure was greater than or equal to the active High
Suction Pressure Shutdown setpoint for its time de-
lay.
High Suction Pressure Warning
- The Suction Pres-
sure was greater than or equal to the active High
Suction Pressure Warning setpoint for its time delay.
High Suction Temp Sensor Warning
– This warning
message is issued if the Suction Temperature read-
ing (analog board 1, channel 1) was to the upper or
maximum range (out of range) for its sensor.
High System Disch Pressure Sensor Warning
– This
warning message is issued if the System Discharge
reading (analog board 1, channel 11) was to the upper
or maximum range (out of range) for its sensor.
Insuf
fi
cient Main Oil Pressure Shutdown
- The Slide
Valve is greater than 50% and the Oil Pressure (PSIA)
is less than or equal to the Suction Pressure (PSIA)
multiplied by 1.5 and then added to 15.0.
Liquid Injection Closed Warning
- This warning will
be triggered when this output is overridden and set
to 0%.
Liquid Slugging Shutdown
- This shutdown is trig-
gered off of a sudden decrease in Discharge Temper-
ature that is greater than the Liquid Slugging Shut-
down setpoint for a
fi
ve (5) second period. That is, if
the Discharge Temperature is 130 degrees F, and the
Liquid Slug Shutdown setpoint is 20 degrees F, then
a sudden drop in Discharge Temperature from 130 to
110 degrees F within a
fi
ve second period will gener-
ate a shutdown condition.
Liquid Slugging Warning
- This warning is triggered
off of a sudden decrease in Discharge Temperature
that is greater than the Liquid Slug Warning setpoint
for a
fi
ve (5) second period. That is, if the Discharge
Temperature is 130 degrees F, and the Liquid Slugging
Warning setpoint is 10 degrees F, then a sudden drop
in Discharge Temperature from 130 to 120 degrees F
within a
fi
ve second period will generate a warning
condition.
Low Auxiliary Analog 1-20 Shutdown
- The Auxil-
iary Analog #1-20 value was less than or equal to the
low Auxiliary Analog #1-20 shutdown setpoint for its
time delay.
Low Auxiliary Analog 1-20 Warning
- The Auxiliary
Analog #1-20 value was less than or equal to the low
Auxiliary Analog #1-20 warning setpoint for its time
delay.
Low Auxiliary Analog Input 1-20 Sensor Warn-
ing
- This warning message is issued if the sensor
connected to the associated Auxiliary Analog Input
channel was below the Low End range for its sensor.
This is strictly a warning, as the compressor does not
stop. This warning is logged into the Event Log.
Low Bal Piston Pressure Sensor Warning
- This
warning message is issued if the Balance Piston Pres-
sure reading (analog board 1, channel 10) was to the
lower or minimum range (out of range) for its sensor.
Low Comp. Oil Pressure Sensor Fault
- This shut-
down message is issued if the Oil Pressure reading
was to the lower or minimum range (out of range)
for its sensor.
Low Comp. Oil Pressure Shutdown
- If the type
of compressor is a Reciprocating type, then a shut-
down will occur if the Oil Pressure minus the Suc-
tion Pressure is less than the Low Comp. Oil Pres-
sure Shutdown setpoint for the period of the delay.
If the compressor type is set for anything other than
Reciprocating, then the shutdown is based upon the
following oil pump con
fi
gurations:
•
No Pump
– A shutdown will occur if the
Discharge Pressure minus the Oil Pressure
is greater than the Low Compressor Oil
Pressure Shutdown Setpoint for the period
of the delay.
•
Full Time
- A shutdown will occur if the Oil
Pressure minus the Discharge Pressure is
less than the Low Compressor Oil Pressure
Shutdown Setpoint for the period of the de-
lay.
•
Demand
- A shutdown will occur if the Dis-
charge Pressure minus the Oil Pressure is
greater than the Low Compressor Oil Pres-
sure Shutdown Setpoint for the period of
the delay.
•
Shaft pump or Shaft Aux. Pump
- A shut-
down will occur if the Oil Pressure minus
the Discharge Pressure is less than the Low
Compressor Oil Pressure Shutdown Setpoint
for the period of the delay.
Low Comp. Oil Pressure Warning
- If the type of
compressor is a Reciprocating type, then a warning
will occur if the Oil Pressure minus the Suction Pres-
sure is less than the Low Comp. Oil Pressure Warning
setpoint for the period of the delay. If the compres-
sor type is set for anything other than Reciprocat-
ing, then the warning is based upon the following oil
