Warning Events List
Sensor Failure
Xe-70M On-Screen Text: 7ATT Failure
This will occur whenever sensor 7ATT is recognized as missing or broken. The
sensor failure message shall follow the following format: 7ATT FAILURE. The
7ATT sensor failure will be shown only when the integrated dryer is installed
(accessed in the factory settings menu). This condition must exist for 3
seconds before the warning is issued.
Change Separator Element
Xe-70M On-Screen Text: Chg Sep Elem
Will occur if the unit is loaded, the package discharge pressure (4APT) is
at least 90 psi and the separator pressure drop is greater than 12 psi. This
condition must exist for 3 seconds before the warning is issued.
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
Will occur if the unit is running and 2ATT is greater than 221 deg F (97% of
228) and the unit is running. This condition must exist for 3 seconds before
the warning is issued.
High Sump Pressure
Xe-70M On-Screen Text: High Sump Pres
If the unit is running loaded, has been loaded for at least 8 seconds and
the sump pressure is more than 25 psi above the rated pressure for the
compressor. If this warning occurs, the online and offl ine pressures will be
reduced. For example, a rated pressure of 100 psi would have a maximum
offl ine pressure of 110 psi. This warning would occur if the sump pressure
goes above 125 psi in this example. This condition must exist for 3 seconds
before the warning is issued.
Note that the Enable 3APT setpoint must be turned ON for this warning to
occur.
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.
EN-38
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 offl ine 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
For R30 – 37 kW compressors this will occur if the dryer condenser or
evaporator temperature switches close. The condenser switch is locking
and must be manually reset before performing a reset on the controller.
The evaporator switch does not latch and can be reset as soon as the signal
opens. If this warning is reset while the conditions for running the dryer exist,
the dryer can restart.
Note that for R4 – 11 kW compressors equipped with a TAS dryer, the dryer
temp warning is triggered when the dewpoint temperature exceeds 14.5
deg C 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.
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, the
measured drop across the HE fi lter is at or above 14 psi (0.7 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.
Invalid Calibration
Xe-70M On-Screen Text: Invalid Cal
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
