When only the short sequence is configured, it will appear as “AUtO” in the display. Otherwise “AUtO1” will indicate
the short sequence and “AUtO2” will indicate the long sequence. The test short sequence will run tests P0 through
P6. The long test sequence will run tests P0 through P10.
A detailed description of the Pre-trip test codes is listed in
. If no selection is made, the Pre-trip menu
selection process will terminate automatically. However, dehumidification and bulb mode must be reactivated man
-
ually if required.
Scrolling down to the “rSLts” code and pressing ENTER will allow the user to scroll through the results of the last
Pre-trip testing run. If no Pre-testing has been run (or an individual test has not been run) since the unit was pow
-
ered up, “- - - -” will be displayed.
NOTE
Pre-trip may also be initiated via communications. The operation is the same as for the keypad initiation
described below except that should a test fail, the Pre-trip mode will automatically terminate. When initiated
via communications, a Pre-trip test may not be interrupted with an arrow key, but the Pre- trip test can be
terminated with the PRE-TRIP key.
5.9.1
Prior to Starting a Pre-Trip
Verify the following conditions prior to starting a pre-trip.
• Unit voltage (Cd07) is within tolerance.
• Unit amperage draw (Cd04, Cd05, Cd06) are within expected limits.
• All alarms are cleared and rectified.
5.9.2
Starting a Pre-Trip
1. Press the PRE-TRIP key to accesses the pre-trip test selection menu.
2. To Run an Automatic Test: Scroll through the selections by pressing the Up or Down Arrow keys to display
AUTO, AUTO 1, AUTO 2 or AUTO 3 as desired, then press the ENTER key.
• The unit will execute the series of tests without any need for direct user interface. These tests vary in
length, depending on the component under test.
• While tests are running, “P#-#” will appear on the left display; the #’s indicate the test number and sub-
test. The right display will show a countdown time in minutes and seconds, indicating the amount of time
remaining in the test.
When an Auto 1 Pre-trip test runs to completion without a failure, the unit will exit Pre-trip
mode and return to normal control operation. However, dehumidification and bulb mode must
be reactivated manually if required.
CAUTION
!
When Pre-trip test Auto2 runs to completion without being interrupted, the unit will terminate
Pre-trip and display “Auto 2” “end.” The unit will suspend operation until the user presses the
ENTER key!
3. When an automatic test fails, it will be repeated once. A repeated test failure will cause “FAIL” to be shown
on the right display, with the corresponding test number to the left. Press the Down Arrow key to repeat the
test, the Up Arrow key to skip to the next test, or the PRE-TRIP key to terminate testing. The unit will wait
indefinitely or until a command is entered.
CAUTION
!
When a failure occurs during automatic testing, the unit will suspend operation awaiting oper
-
ator intervention.
4. To Run an Individual Test: Scroll through the selections by pressing the Up or Down Arrow keys to display
an individual test code. Press the ENTER key when the desired test code is displayed.
