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
For R30-37 kW, the VSD fault is read from drive, controller only shows VSD
FAULT. Once fault is eliminated from drive, VSD fault can be cleared by
pressing the reset button and machine can be restarted.
For R37e-160 kW, 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 39 – 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 39 – 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 39 – 42 or 44. VSD faults
39, 40, and 41 (IGBT failures) have additional logic associated with them.
Due to false trips the logic was modifi ed to allow an automatic restart. If the
VSD fault 39, 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 fi ve automatic
restarts of VSD Fault 39 – 41 within a 24 hour period. The controller will also
not allow two automatic restarts of VSD Fault 39 – 41 within a 10 minute
period. If a VSD Fault 39 – 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 fi ve times
in a one hour period. If the compressor exceeds fi ve 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 13 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 fi lter 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.
EN-26
Control Power Loss
This will occur if the compressor should be running and the AC input voltage,
as read from the VSD, falls below 100 VAC. There is a delay of 2 seconds on
this trip in case the power quickly returns. A phase monitor is something that
can cause this trip.
Stop Failure
This will occur if the compressor should be stopped, but the motor speed has
not dropped below the minimum motor speed set point. The controller will
wait 4 seconds for the compressor to stop before issuing this trip.
High Interstage Pressure
This will occur if the compressor is running, is a two stage compressor, and
the interstage pressure is above 75 psi.
High Coolant Filter Pressure Drop
This will occur if the compressor has been running for at least seven seconds,
the injected coolant temperature is at least 140 °F, already has a change
coolant fi lter warning, the motor speed is at least equal to the minimum
speed, and the coolant fi lter pressure drop (5CPT - 6CPT) is greater than
35 psi.
High Inlet Vacuum
This will occur if the compressor is running loaded, the motor speed is at least
minimum speed, and the inlet vacuum is greater than 1.8 psi (vacuum).
High Sump Pressure
This will occur if the compressor is running and any one of the three
following conditions exist: (1) The sump pressure is above the target pressure
by 25 psi. (2) The separator pressure drop is measured to be more than 25 psi
and the package discharge pressure is at least 65 psi. (3) The sump pressure is
above 168 psi.
Start Inhibit List
High Airend Discharge Temperature
This will occur if 2ATT is greater than 95% of 228 °F.
High Sump Pressure
This will occur if the sump pressure (3APT) is 25 psi or higher than the rated
pressure of the compressor.
Waiting for VSD Comms
This will occur if the compressor VSD has not responded to the initial
communications from the controller.

Figure 44 : Trip History
The pages in the Trip History folder document up to the last 15 trips that the
controller has experienced, and time stamps each. The trips are recorded in
sequence, with number one being the newest and 15 being the oldest. When
a new trip occurs, it becomes number one and all others are shifted up in
number.
The page numbers in the Title Bar are used to scroll through the events, with
each page displaying up to seven. Page one displays events one through fi ve,
