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,

The time and date of the event can be viewed by navigating to an event and

WARNING EVENTS LIST

•
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 105°C (221°F) (97%
of 109°C [228°F]) or the unit is in idle mode (3.3.7.1) and 2ATT is greater than
84.4°C (184°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 first "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 of 56.1°C (133°F). This condition must exist for 3 seconds
before the warning is issued.
•
Dryer Temp Warning
Xe-70M On-Screen Text: Dryer Temp
Note that 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. If this warning
is reset while the conditions for running the dryer exist, the dryer can restart.
