Service
Service warnings occur when the compressor 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
If service level 1 has been selected for the compressor, 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
If service level 2 has been selected for the compressor, 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.
Communication Failure
This will occur if the compressor is the lead compressor in integral
sequencing and is unable to communicate with another compressor.
Sensor Failure 10APT – Remote Sensor
This will occur if the remote sensor option is on and the remote sensor
is recognized as missing or broken. If this occurs, the compressor will
automatically start using 4APT for loading and unloading the compressor.
Units equipped with an integrated dryer cannot have a remote pressure
sensor. This condition must exist for  seconds before the warning is issued.
High Discharge Pressure
Will occur if the compressor is using a remote sensor or is under the control
of an external device, such as an 8XI, is loaded, and the discharge pressure
(4APT) is greater than the maximum offline pressure. This condition must
exist for  seconds before the warning is issued. If this condition occurs, the
compressor will automatically unload. The compressor will be available to
reload once the discharge pressure falls to the rated pressure value.
Condensate Drain Error
This will occur if the compressor is running, the package discharge pressure
is over 50 psi, and the condensate drain error contact closes for at least 240
seconds. This warning will be ignored for 4.5 minutes after starting.
Freeze Warning
This will occur if the evaporator sensor has a value of 687 (about 0.5 C)
or below (low temp) while the dryer is running, on compressors with the
integrated dryer. This is a dryer fault. If this happens, the compressor will
continue to run, but the dryer will stop. The condition must exist for at least
180 seconds before the warning will occur. NOTE: If this warning is reset
while the conditions for running the dryer exist, the dryer can restart. Also the
dryer can restart if the evaporator value rises to 709 (about 5 C). However the
warning will still be displayed.
Dryer High Pressure
On compressors 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  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 switch must be
reset before the dryer can run. Resetting the warning on the display does not
reset the switch.

Condenser Temperature High
This will occur if the condenser sensor has a value above high temperature
threshold while the dryer is running, on compressors with the integrated
dryer. This is not a dryer fault. If this happens, the compressor and dryer will
continue to run. The condition must exist for at least 180 seconds before the
warning will occur.
Condenser Temperature Low
This will occur if the condenser sensor has a value below the low temperature
threshold while the dryer is running, on compressors with the integrated
dryer. This is not a dryer fault. If this happens, the compressor and dryer will
continue to run. The condition must exist for at least 180 seconds before the
warning will occur.
Change HE Filter
The HE filter is located between the aftercooler discharge and the inlet to the
dryer and is only on compressors with an integrated dryer. The drop across
the HE filter is measured by subtracting the package discharge pressure
from the aftercooler discharge pressure. If the compressor is running,
the measured drop across the HE filter is at or above 10 psi (0.7 bar), the
compressor is hot (injected coolant temp above 120 °F), and the package
discharge pressure (4APT) is above 90 psi, this warning can occur. The
condition must exist for at least  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.
Low Sump Pressure
Will occur if the compressor is running unloaded or loaded and APT is less
than 1 psi for 15 seconds.
High Airend Discharge Temperature
This will occur if 2ATT is greater than 228 °F and the compressor is running.
Check Motor Rotation
This will occur if APT is less than 1 psi on a compressor,  seconds after
starting (6 seconds if the compressor is equipped with a soft starter or airend
discharge temperature is less than 50 °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.
Main Motor Overload
This will occur if the motor overload relay contact opens. The contact must
be open for at least  seconds before the trip will occur.
Fan Motor Overload
Will occur if a fan motor overload relay contact opens. The contact must be
open for at least  seconds before the trip will occur.
Remote Stop Failure
Will occur if the remote start/stop option is enabled, the remote stop button
remains open and either start button is pressed.
Remote Start Failure
Will occur if the remote start/stop option is enabled, the compressor is
started by the remote start button, and the button stays closed for 7 seconds
after the compressor starts.
Sensor Failure
This will occur when a sensor is recognized as missing or broken. The sensors
affected by this trip are 1AVPT, APT, 4APT, 5CPT, 6CPT, 2APT (if 2 stage
compressor), 2CTT, and 2ATT. The sensor should be displayed along with the
sensor failure message. The sensor failure message shall follow the following
format: SENSOR FAILURE 1AVPT.
Emergency Stop
This will occur when the emergency stop button is engaged.
