Figure 45 : 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.
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.

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
