WARNING EVENTS LIST

•
High Airend Discharge Temperature
Xe-70M On-Screen Text: High A/E Disch T
Will occur if the unit is running and 2ATT is greater than 105 °C (221 °F) (97%
of 109°C [228°F]). This condition must exist for 3 seconds before the warning
is issued.
•
Service
Service warnings occur when the unit has operated a certain number of
hours, based on the total hours. Service warnings can have multiple levels,
depending on the service level selection. A service level selection of 0
disables service warnings.
•
Service Level 1
Xe-70M On-Screen Text: SVC Required
If service level 1 has been selected for the unit, a "SERVICE REQUIRED"
warning will be issued on hour intervals equal to the service time period set
point. This warning can be reset the same as any other warning.
•
Service Level 2
Xe-70M On-Screen Text: 100 hours to SVC, SVC Required, Service Alarm
If service level 2 has been selected for the unit, the service complete factory
set point will be used to clear a level 2 service warning and reset the service
time or date. The service complete can be reset before a service warning
occurs.
The initial "SERVICE REQUIRED" warning will occur at total hour intervals
equal to the service time period set point. However, 100 hours before this a
"100 HOURS TO SERVICE" warning will occur. This warning can be reset the
same as any other warning. One hundred hours later the "SERVICE REQUIRED"
warning will occur. This warning can be reset the same as any other warning,
however this warning will return in 24 hours if the service complete factory
set point has not be set. If the service complete has not been set, 100 hours
later, the "ALARM – SERVICE REQUIRED" warning will be issued. This warning
can only be cleared by the service complete factory set point. Once the
service complete factory set point is set, indicating the service is completed,
the time for the next "SERVICE REQUIRED" warning will be calculated by
adding the service time period to the total hours value, with the "100 HOURS
TO SERVICE" warning occurring 100 hours before and the "ALARM – SERVICE
REQUIRED" warning occurring 100 hours after that time.
•
High Discharge Pressure
Xe-70M On-Screen Text: High Disch Pres
Will occur if the unit is using a remote sensor or is under the control of an
external device, such as an X8I, is loaded, and the discharge pressure (4APT)
is greater than the maximum offline pressure. This condition must exist for 3
seconds before the warning is issued. If this condition occurs, the compressor
will automatically unload. The unit will be available to reload once the
discharge pressure falls to the rated pressure value.
•
Dryer Temp Warning
Xe-70M On-Screen Text: Dryer Temp
Compressors equipped with a TAS dryer, the dryer temp warning is triggered
when the dewpoint temperature exceeds 14.5 °C (58.1 °F) for 6 minutes or longer.
This warning can also be triggered if the temperature probe in the dryer fails.
•
Dryer High Pressure
Xe-70M On-Screen Text: Dryer High Pres
On units with the 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 3 seconds before the warning will occur. 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
Will occur if the sensor zero value is ± 10% of its scale. See Sensor Calibration.


•
Xe-70M On-Screen Text: High A/E Disch T
This will occur if 2ATT is greater than 109 °C (228 °F) and the unit is running.
•
Xe-70M On-Screen Text: Overload
This will occur if the fan or main motor overload relays open. The contact
must be open for at least 3 seconds before the trip will occur.
Xe-70M On-Screen Text: Main Motor OL
This will occur if the current transformers indicate that the motor amp draw is
excessive. This overload is the equivalent of a class 10A trip level.
This trip is only applicable for compressors with current transformers
installed.
•
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.
•
Xe-70M On-Screen Text: Rem Start Fail
Will occur if the remote start/stop option is enabled, the unit is started by the
remote start button, and the button stays closed for 7 seconds after the unit
starts.
•
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.
•
Xe-70M On-Screen Text: Emergency Stop
This will occur when the EMERGENCY STOP button is engaged.
•
Xe-70M On-Screen Text: Unit Too Cold
This will occur if the unit does not have the low ambient option, the airend
discharge temperature (2ATT) is less than 1.6 °C (35 °F), and the operator
attempts to start the compressor. This fault can only occur once a day. Once
this fault occurs, the operator can reset it and start the compressor. This fault
will be logged in the trip history to indicate that the unit is being started in
low ambient conditions.

•
Xe-70M On-Screen Text: High A/E Disch T
This will occur if 2ATT is greater than 95% of 109°C (228°F), which is 103°C
(217°F).
