warning are 7APT, 5DTT, and 6DTT. The sensor failure message shall follow
the following format: SENSOR FAILURE 7APT.
Change Separator Element
This will occur if the compressor has been running for at least 7 seconds,
the injected coolant temperature is at least 120 °F, 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.
High Airend Disch Temp
Will occur if the compressor is running and 2ATT is greater than 221 °F (97%
of 228) or the compressor is in idle mode (3.3.7.1) and 2ATT is greater than
184 °F. This warning will normally have a 5 second delay, however, if the hot
side thermal valve (3.3.1.5) is set to ON, this warning will have a 90 second
delay.
High Discharge Press
Will occur if the compressor is under the control of an external device, such
as an X-series, and the discharge pressure is greater than the immediate stop
pressure.
Auxiliary Warning 1 (2)
This will occur if the auxiliary warning input closes.
Service
Service warnings could change signifi cantly once the predictive maintenance
warnings have been determined.
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. Selecting service level 0 disables
service warnings.
Service Level 1
If service level 1 (3.3.1.9) has been selected for the compressor, a "SERVICE
REQUIRED" warning will be issued the amount of operating hours in the
Service Time Period set point (3.3.1.10). 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 (3.3.1.11) 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 (3.3.1.10). 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.
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.
High VSD Ambient Temperature
This warning will occur if the VSD ambient temperature gets within 5% of the
shutdown value (133 °F).
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
80447162 Rev B
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 an 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 three 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.
Sensor Failure Remote
This will occur whenever the remote sensor is recognized as missing or
broken. The sensor failure message shall follow the following format:
SENSOR FAILURE REMOTE. If this warning occurs, the compressor will
automatically switch to the package discharge pressure sensor for control.
High Sump Pressure
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 (see 4.11).
Condenser Temperature High
This will occur if the condenser sensor has a value of 1019 (about 65 °C)
or above (high temp) 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 of 887 (about 40 °C)
or below (low temp) 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 across
the HE fi lter is measured by subtracting the package discharge pressure
from the after-cooler discharge pressure. If the compressor is running at a
minimum of 75% capacity, the measured drop across the HE fi lter 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 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.
Trip Events List
High Airend Disch Temp
This will occur if 2ATT is greater than 228 °F during normal operation. This
trip will occur at 200 °F if the compressor is in idle mode.
Blower Fault
Will occur if the fault contact opens for 3 seconds on the blower VSD.
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 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
aff ected by this trip are 4APT, 3APT, 2APT, 1AVPT, 5CPT, 6CPT, and 2ATT. The
