Control Power Loss
This will occur if the compressor should be running and the AC input voltage,
as read from the VSD, falls below 100 VAC. There is a delay of 2 seconds on
this trip in case the power quickly returns. A phase monitor is something that
can cause this trip.
Stop Failure
This will occur if the compressor should be stopped, but the motor speed has
not dropped below the minimum motor speed set point. The controller will
wait 4 seconds for the compressor to stop before issuing this trip.
High Interstage Pressure
This will occur if the compressor is running, is a two stage compressor, and
the interstage pressure is above 75 psi.
High Coolant Filter Pressure Drop
This will occur if the compressor has been running for at least seven seconds,
the injected coolant temperature is at least 140°F, already has a change
coolant filter warning, the motor speed is at least equal to the minimum
speed, 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, the motor speed is at least
minimum speed, and the inlet vacuum is greater than 1.8 psi (vacuum).
High Sump Pressure
This will occur if the compressor is running and any one of the three
following conditions exist: (1) The sump pressure is above the target pressure
by 25 psi. (2) The separator pressure drop is measured to be more than 25 psi
and the package discharge pressure is at least 65 psi. () The sump pressure
is above 168 psi.
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.
Waiting for VSD Comms
This will occur if the compressor VSD has not responded to the initial
communications from the controller.

Start Inhibit List
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.
The following actions 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 pressing
the enter button will activate the trip history dialog box.
Figure 66: Trip History Dialog
While the dialog box is active, press the left and right keys 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.
