Active Trips will be highlighted in red while cleared Trips will have red text.
Active Start Inhibits will be listed in the Event log, but not highlighted. The
display will indicate the compressor is not ready to start if a start inhibit is
active.
See the following lists for details about messages in each type of event.
Change Inlet Filter
Will occur if 1AVPT is greater than 0.7 psi vacuum (or 1.3 psi vacuum if the
high dust fi lter option is enabled) and the compressor has been loaded for at
least 8 seconds. This condition must exist for 3 seconds before the warning
is issued.
Change Coolant Filter
This will occur if the compressor has been running loaded for at least 8
seconds, is warmed up, and the coolant fi lter pressure drop (5CPT - 6CPT)
is greater than 25 psi. This condition must exist for 3 seconds before the
warning is issued.
Sensor Failure
This will occur whenever sensors 4ATT, 5DTT, 6DTT, and 7APT are recognized
as missing or broken. The sensor failure message shall follow the following
format: SENSOR FAILURE 4ATT. The 5DTT, 6DTT, and 7APT sensor failures 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
Will occur if the compressor is loaded, the compressor is warmed up (the
injected coolant temperature is at least 120 °F), the package discharge
pressure 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.
High Airend Discharge Temperature
Will occur if the compressor is running and 2ATT is greater than 221 °F (97%
of 228) and the compressor is running. This condition must exist for
3 seconds before the warning is issued.
High Sump Pressure
If the compressor 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.
Auxiliary 1
This will occur if auxiliary input 1 closes. The contact must be closed for at
least 3 seconds before the warning will occur.
Auxiliary 2
This will occur if auxiliary input 2 closes. The contact must be closed for at
least 3 seconds before the warning will occur.
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
EN-16
Warning Events List
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 3 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 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 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 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 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 fi lter is located between the after-cooler discharge and the inlet to
the dryer and is only on compressors with an integrated dryer. The drop
