Change HE Filter
Xe-70M On-Screen Text: Change HE Filt
The HE fi lter is located between the after-cooler discharge and the inlet to
the dryer and is only on units with an integrated dryer. The drop across the
HE fi lter is measured by subtracting the package discharge pressure from the
after-cooler discharge pressure. If the compressor is running at a minimum
of 75% capacity, the measured drop across the HE fi lter is at or above 14 psi
(1.0 bar), and the package discharge pressure (4APT) is above 90 psi, this
warning can occur. The condition must exist for at least 3 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.
Note that the Enable 7APT setpoint must be turned ON for this warning to
occur
Replace Coolant Filter
Xe-70M On-Screen Text: Chg Rplc Coolant Filt
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.
Invalid Calibration
Xe-70M On-Screen Text: Invalid Cal
This will occur if the sensor zero value is ± 10% of its scale.
Trip Events List
High Airend Disch Temp
Xe-70M On-Screen Text: High A/E Disch T
This will occur if 2ATT is greater than 228 deg F during normal operation. This
trip will occur at 200 deg F if the unit is in idle mode.
Overload
Xe-70M On-Screen Text: Overload
This will occur if the fan overload relay opens. The contact must be open for
at least 3 seconds before the trip will occur.
Remote Stop Failure
Xe-70M On-Screen Text: Rem Stop Fail
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
Xe-70M On-Screen Text: Rem Start Fail
Will occur if the unit is started by the remote start button and the button
stays closed for 7 seconds after the unit starts.
Sensor Failure
Xe-70M On-Screen Text: 3APT Failure, 4APT Failure, 7APT Failure, 2ATT Failure,
Main Motor CT Failure
This will occur when a sensor is recognized as missing or broken. The sensors
aff ected by this trip are CT1, CT2, CT3, 3APT, 4APT, 7APT, and 2ATT. The sensor
should be displayed along with the sensor failure message. The sensor failure
message shall follow the following format: 3APT Failure.
Emergency Stop
Xe-70M On-Screen Text: Emergency Stop
This will occur when the EMERGENCY STOP button is engaged.
VSD Fault X
Xe-70M On-Screen Text:
The compressors variable speed drive is reporting a fault. Please refer to the
troubleshooting guide for further information.
Low Sump Pressure
Xe-70M On-Screen Text: Low Sump Press
Will occur if the compressor is operating and the sump pressure drops below
13 psi for 15 seconds.
EN-48
Note that the Enable 3APT setpoint must be turned ON for this warning to
occur.
Check Motor Rotation
Xe-70M On-Screen Text: Ck Motor Rot
This will occur if the controller reads a negative speed from the VSD when
starting.
VSD Communication Failure
Xe-70M On-Screen Text: VSD Comm Fail
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.
Incorrect VSD Type
Xe-70M On-Screen Text: Wrong 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.
Stop Failure
Xe-70M On-Screen Text: 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. This is
normally an indication the run relay (K1) did not open when de-energized.
Because of this, the isolation contact should open when this fault occurs. The
isolation contact can close when this fault is cleared, if the unit is not water
cooled.
High Sump Pressure
Xe-70M On-Screen Text: High Sump Pres
This will occur if the compressor is running and any one of the 3 following
conditions exist. (1) The sump pressure is above the target pressure by 25 psi
(32 PSI if the dryer is enabled). (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 for a machine with rated pressure of 145
psi.
Note that the Enable 3APT setpoint must be turned ON for this warning to
occur
VSD Initialization Fault
Xe-70M On-Screen Text: Drive Init Error
This will occur if the controller is unable to properly set-up the drive after
boot or after a reset. The controller will attempt to write a parameter 10 times
to the drive, after these 10 attempts have failed this trip will be registered.
Xe-70M On-Screen Text: VSD Comm Except
This will occur if the controller receives invalid communications from the VSD.
Please refer to the troubleshooting guide for further information.
Start Inhibit List
High Airend Discharge Temperature
Xe-70M On-Screen Text: High A/E Disch T
This will occur if 2ATT is greater than 95% of 228 deg F.
High Sump Pressure
Xe-70M On-Screen Text: High Sump Pres
This will occur if the sump pressure (3APT) is 25 psi or higher than the rated
pressure of the compressor.
Please note that the Enable 3APT setpoint must be turned ON for this
warning to occur
VSD Intialization
Xe-70M On-Screen Text: VSD Initializing
This will occur if the compressor VSD has not responded to the initial
communications from the controller.
