However, this switch is a locking switch. The dryer high pressure switch must
be reset (contact closed) before this warning can be reset. If this warning is
reset while the conditions for running the dryer exist, the dryer can restart.

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 109 °C (228 °F) during normal operation.
This trip will occur at 93 °C (200 °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: 4APT Failure, 2ATT Failure, Main Motor CT Failure
This will occur when a sensor is recognized as missing or broken. The sensors
affected by this trip are CT1, CT2, CT3, 4APT, and 2ATT. The sensor should be
displayed along with the sensor failure message. The sensor failure message
shall follow the following format: 4APT 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: VSD Fault 'X'"
The compressors variable speed drive is reporting a fault. Refer to the
troubleshooting guide for further information.
•
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.

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.
•
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.
Refer to the troubleshooting guide for further information.

•
Xe-70M On-Screen Text: High A/E Disch T
This will occur if 2ATT is greater than 95% of 109 °C (228 °F) .
•
Xe-70M On-Screen Text: VSD Initializing
This will occur if the compressor VSD has not responded to the initial
communications from the controller.

•
The pages in the Trips 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 five,
page two displays six through ten, and so on.
The following items will generate an entry in the trip history.
•
Active Trips will show a flashing trip icon
have a solid icon.
The trip history also records compressor data at the time of the trip to assist
in diagnostics and troubleshooting. Navigating to the trip entry and hitting
the enter button will bring up the trip history dialog box.
