across the HE fi lter 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 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.
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 and the compressor is running.
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.
Fan Motor Overload
Will occur if a fan motor overload relay contact opens. 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
aff ected by this trip are 1AVPT, 3APT, 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.
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 fi lter warning, and the
coolant fi lter pressure drop (5CPT - 6CPT) is greater than 35 psi.
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 fi lter, the trip threshold
for inlet vacuum is 2.4 psi.
Unit Too Cold To Start
This will occur if the compressor does not have the low ambient option,
the airend discharge temperature (2ATT) is less than 35 °F, and the operator
attempts to start the compressor. This fault can only occur once a day. Once
80447162 Rev B
Trip Events List
this fault occurs, the operator can reset it and start the compressor. This fault
will be logged in the trip history to indicate that the compressor is being
started in low ambient conditions.
High Interstage Pressure
This will occur if the compressor is running and the interstage pressure
(2APT) is greater than 75 psi. This trip will only occur in 2 stage compressors.
Invalid Calibration
Will occur if the sensor zero value is +/- 10% of its scale. This will only occur
when a sensor is calibrated.
Start Inhibit List
High Airend Discharge Temperature
This will occur if 2ATT is greater than 95% of 228 °F.
High Sump Pressure
This will occur if the sump pressure (3APT) is 25 psi or higher than the rated
pressure of the compressor.

Figure 18 : Trip History
The pages in the Trip History folder document up to the last 15 trips that the
controller has experienced, and time stamps each. The trips are recorded in
sequence, with number one being the newest and 15 being the oldest. When
a new trip occurs, it becomes number one and all 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 fi ve,
page two displays six through ten, and so on.
The following items will generate an event.
• Power ON
• Power OFF
• Press the Start Key
• Press the Stop Key
• Press the Load Key
• Press the Unload Key
• Warning
• Trip
• Start Inhibit
Active Trips will be highlighted in red while cleared Trips will have red text.
The trip history also records compressor data at the time of the trip to assist
in diagnostics and troubleshooting. Navigating to the trip entry and hitting
the enter button will bring up the trip history dialog box.
