OPERATING INSTRUCTIONS (XE-70M CONTROLLER)
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 High Pressure ( Not available on this compressor
model)
Xe-70M On-Screen Text: Dryer High Pres
Xe-70 Dryer Controls are not linked to UP Series 15-
30HP/11-22kW dryers��
Change HE Filter ( Not available on this compressor
model)
Xe-70M On-Screen Text: Change HE Filt
Note that the Enable 7APT setpoint must be turned ON
for this warning to occur��
Invalid Calibration

Will occur if the sensor zero value is ± 10% of its scale�� See
Sensor Calibration��
Trip Events List
Low Sump Pressure
Xe-70M On-Screen Text: Low Sump Press
Will occur if the unit is running unloaded or loaded and
3APT is less than 13 psi for 15 seconds��
Note that the Enable 3APT setpoint must be turned ON
for this warning to occur
High Airend Discharge Temperature
Xe-70M On-Screen Text: High A/E Disch T
This will occur if 2ATT is greater than 228 deg F and the
unit is running��
Check Motor Rotation
Xe-70M On-Screen Text: Ck Motor Rot
This will occur if 3APT is less than 1 psi on a unit, 3
seconds after starting (6 seconds if the unit is equipped
with a soft starter or airend discharge temperature is
less than 50 deg F)�� This condition can be caused by the
motor running in reverse�� Once correct motor rotation
is established, this trip will not be checked again unless
power is removed from the controller�� However, if correct
motor rotation is not established, this fault will be
checked after each start until correct motor rotation is
established�� Correct motor rotation is established when
the controller reads a sump pressure of 1 psi or more
within 3 seconds of starting��
Note that the Enable 3APT setpoint must be turned ON
for this warning to occur��
Overload
Xe-70M On-Screen Text: Overload
This will occur if the fan or motor overload relays opens��
