High Sump Pressure
This will occur if the compressor is running loaded for at least 8 seconds, and
any one of the  following conditions exist. (1) The sump pressure is above
the rated pressure by 5 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. () 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) is greater than 5 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 filter, 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 5°F, and the operator
attempts to start the compressor. This fault can only occur once a day. Once
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.
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 (APT) is 25 psi or higher than the rated
pressure of the compressor.

Trip history


Pages 1-4 (max .)
Figure 39: 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 five,
page two displays six through ten, and so on.

Start Inhibit List

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.
Figure 40: Trip History Dialog
While the dialog box is active, press the left and right keys in order to scroll
through the displayed data. The name of the trip will always be shown in
the title bar of the dialog box. Press enter when finished viewing the data to
return to the trip history screen.
