Freeze Warning
This will occur if the evaporator sensor has a value of 687 (about 0.5 C)
or below (low temp) while the dryer is running, on compressors with the
integrated dryer. This is a dryer fault. If this happens, the compressor will
continue to run, but the dryer will stop. The condition must exist for at least
180 seconds before the warning will occur. NOTE: If this warning is reset
while the conditions for running the dryer exist, the dryer can restart. Also
the dryer can restart if the evaporator value rises to 709 (about 5 C). However
the warning will still be displayed.
Dryer High Pressure
On compressors with an integrated dryer, this will occur if the dryer high
pressure switch opens while the dryer is running. This is a dryer fault. If this
happens, the compressor will continue to run, but the dryer will stop. The
contact must be open for at least three seconds before the warning will
occur. If this warning is reset while the conditions for running the dryer exist,
the dryer can restart. However, this switch is a locking switch. The switch
must be reset before the dryer can run. Resetting the warning on the display
does not reset the switch.
Sensor Failure Remote
This will occur whenever the remote sensor is recognized as missing or
broken. The sensor failure message shall follow the following format:
SENSOR FAILURE REMOTE. If this warning occurs, the compressor will
automatically switch to the package discharge pressure sensor for control.
High Sump Pressure
This will occur if the compressor is running, the package discharge pressure
is at least 65 psi, and the sump pressure is more than 15 psi above the target
pressure. The occurrence of this warning will cause the controller to evaluate
the need to lower the maximum speed (see 4.11).
Condenser Temperature High
This will occur if the condenser sensor has a value of 1019 (about 65 C) or
above (high temp) while the dryer is running, on compressors with the
integrated dryer. This is not a dryer fault. If this happens, the compressor and
dryer will continue to run. The condition must exist for at least 180 seconds
before the warning will occur.
Condenser Temperature Low
This will occur if the condenser sensor has a value of 887 (about 40 C) or
below (low temp) while the dryer is running, on compressors with the
integrated dryer. This is not a dryer fault. If this happens, the compressor and
dryer will continue to run. The condition must exist for at least 180 seconds
before the warning will occur.
Change HE Filter
The HE filter is located between the aftercooler discharge and the inlet to the
dryer and is only on compressors with an integrated dryer. The drop across
the HE filter is measured by subtracting the package discharge pressure
from the aftercooler discharge pressure. If the compressor is running at a
minimum of 75% capacity, the measured drop across the HE filter is at or
above 10 psi (0.7 bar), the compressor is hot (injected coolant temp above
120 °F), and the package discharge pressure (4APT) is above 90 psi, this
warning can occur. The condition must exist for at least  seconds before the
warning will occur. This is not a dryer fault. If this happens, the warning will
be displayed, but the dryer will continue to run.
High Airend Disch Temp
This will occur if 2ATT is greater than 228 °F during normal operation. This
trip will occur at 200 °F if the compressor is in idle mode.
Blower Fault
Will occur if the fault contact opens for  seconds on the blower VSD.
Remote Stop Failure
Will occur if the REMOTE START/STOP option is enabled, the remote stop
button remains open and either start button is pressed.
Remote Start Failure
Will occur if the compressor is started by the remote start button and the
button stays closed for 7 seconds after the compressor starts.

Trip Events List
Sensor Failure
This will occur when a sensor is recognized as missing or broken. The sensors
affected by this trip are 4APT, APT, 2APT, 1AVPT, 5CPT, 6CPT, and 2ATT. The
sensor should be displayed along with the sensor failure message. The
sensor failure message shall follow the following format: SENSOR FAILURE
4APT. Sensor 4APT has the following additional logic. A sensor failure 4APT
will be issued if the sump pressure is over 100 psi and the package discharge
pressure (4APT) is 50 psi less than the sump pressure.
Emergency Stop
This will occur when the EMERGENCY STOP button is engaged.
VSD Fault
The VSD fault is read from the drive. The controller will read the status
menu of the variable speed drive. If a fault condition is returned in the
status information, the controller will issue a VSD FAULT trip and display the
number of the fault condition. VSD faults 9 – 42 and 44 cannot be cleared
by pressing the reset button. All other VSD faults can be cleared by pressing
the reset button. The only way to clear a VSD fault 9 – 42 or 44 is by cycling
the power on the compressor. Cycling the power causes the VSD to execute
a power module test. The power module test must be passed before the
compressor can be restarted after a VSD fault 9 – 42 or 44. VSD faults 9,
40, and 41 (IGBT failures) have additional logic associated with them. Due
to false trips the logic was modified to allow an automatic restart. If the
VSD fault 9, 40, or 41 occurs, the controller will trip and display the fault
message. After two minutes, the controller will issue a command to the VSD
to run the power module test. While the VSD is running the power module
test, the controller will force itself into a reset. Upon completing the reset,
the controller will monitor the VSD for completion of the power module test.
If the power module test is completed and all conditions have passed, the
controller will automatically restart the compressor. If the power module
test is failed, the controller will show the power module test failure message
and the failure code. The controller will not allow more than five automatic
restarts of VSD Fault 9 – 41 within a 24 hour period. The controller will also
not allow two automatic restarts of VSD Fault 9 – 41 within a 10 minute
period. If a VSD Fault 9 – 41 occurs and violates the time periods, the
controller will not issue a power module test and restart. It will display the
fault and not allow a reset from the controller. The operator must cycle
power. Another exception on all drives are VSD faults 10, 12 – 14, and 16. If
the compressor trips due to one of these faults, instead of shutting down
on the VSD fault, the controller will reset and then restart the compressor.
If the compressor is equipped with a power outage restart option (PORO),
the controller will execute a PORO restart. If the compressor does not
have PORO, the controller will restart the compressor 10 seconds after the
controller has reset. A compressor will be allowed to do this up to five times
in a one hour period. If the compressor exceeds five occurrences within a one
hour period, the sixth occurrence will be treated like a regular VSD fault.
Low Sump Pressure
This will occur if the compressor is operating and the sump pressure drops
below 1 psi for 15 seconds.
Check Motor Rotation
This will occur if the controller reads a negative speed from the VSD when
starting.
VSD Communication Failure
This will occur if the controller does not receive a response from the VSD
when requesting information. This trip will take about 8 seconds to occur.
VSD Initialization Fault
This will occur if the controller is unable to establish communications with
the VSD after a power up.
Replace Coolant Filter
This will occur if the idle mode is set to on. This trip is used as a reminder
to Ingersoll Rand service to only use idle mode if a new coolant filter is
installed.
Incorrect VSD Type
This will occur at power up if the VSD type does not match the size of
compressor. The controller will determine this by comparing the compressor
type with the drive ID board.
