•
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 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
30 minutes. This warning will be ignored for 4.5 minutes after starting.
•
Freeze Warning
This will occur if the evaporator sensor has a value of 678 (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 filter 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 filter is measured by subtracting the package discharge
pressure from the after-cooler discharge pressure. If the compressor is
running, the measured drop across the HE filter is at or above 14 psi (0.9
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.
•
Invalid Calibration
Will occur if the sensor zero value is +/- 10% of its scale. This will only occur
when a sensor is calibrated.
TRIP EVENTS LIST
•
Low Sump Pressure
Will occur if the compressor is running unloaded or loaded and 3APT is less
than 13 psi for 15 seconds.
•
High Airend Discharge Temperature
This will occur if 2ATT is greater than 228 °F.
•
Check Motor Rotation
This will occur if 3APT is less than 1 psi on a compressor, 3 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 3 seconds before the trip will occur. This trip will not
occur if there is an active Emergency Stop trip.
•
Fan Motor Overload
Will occur if a fan motor overload relay contact opens and the compressor is
not equipped with a variable speed blower. The contact must be open for at
least 3 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, 3APT, 4APT, 5CPT, 6CPT, 2APT (if 2 stage
compressor), 7APT (if integrated dryer), 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. Sensor Failure
1AVPT will only occur if the compressor is running and loaded.
•
Emergency Stop
This will occur when the emergency stop button is engaged.
•
High Sump Pressure
This will occur if the compressor is running loaded for at least 8 seconds, and
any one of the 3 following conditions exist. (1) The sump pressure is above
the rated pressure by 35 psi. (2) The separator pressure drop is measured to
be more than 25 psi and the package discharge pressure at least equal to the
minimum online set point value. (3) The sump pressure is above 165 psi if the
rated pressure is less than 190 psi or the sump pressure is above 220 if the
rated pressure is 190 psi.
•
High Coolant Filter Pressure Drop
This will occur if the compressor has been running loaded for at least 8
seconds, is warmed up, already has a change coolant filter warning, and the
coolant filter pressure drop (5CPT - 6CPT) has been greater than 35 psi for 10
seconds.
•
High Inlet Vacuum
This will occur if the compressor is running loaded and the inlet vacuum is
greater than 1.8 psi. If the compressor has a high dust filter, the trip threshold
for inlet vacuum is 2.4 psi.
