active.
Warning Events List
Change Separator Element
Xe-70M On-Screen Text: Chg Sep Elem
This will occur if the unit has been running for at least 15 seconds, the
package discharge pressure is at least 65 psi, and the separator pressure drop
is at least 12 psi. If the target pressure is less than 90 psi, the warning value
will increase 1 psi per 5 psi in reduced target pressure. For example, if the
target pressure is between 89 and 85 psi, the warning value will be 13 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 Disch Temp
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) or the unit is in idle mode (3.3.7.1) and 2ATT is greater than 184 deg F.
This warning will have a 90 second delay.
High Discharge Press
Xe-70M On-Screen Text: High Disch Press
Will occur if the unit is under the control of an external device, such as an
X-series system controller, and the discharge pressure is greater than the
immediate stop pressure for a time period of 3 seconds. At this point, the
controller will unload the compressor until package discharge pressure falls
back below the target pressure setpoint.
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. Selecting service level 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 the amount of operating hours in 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 Hrs 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 fi rst "SERVICE REQUIRED" warning will occur at the total hours value
of 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, at the total hours value of the
service time period, 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 (service time period + 100)
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 VSD Ambient Temperature
Xe-70M On-Screen Text: High VSD Amb T
This warning will occur if the VSD ambient temperature gets within 5% of the
shutdown value (133 deg F). This condition must exist for 3 seconds before
the warning is issued.
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. If this warning
is reset while the conditions for running the dryer exist, the dryer can restart.
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.
High Sump Pressure
Xe-70M On-Screen Text: High Sump Pres
This will occur if the compressor is running, the package discharge pressure
is at least 65 psi, and the sump pressure is more than 15 psi above the target
pressure. The occurrence of this warning will cause the controller to evaluate
the need to lower the maximum speed. 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
