Pretrip
A Pretrip Test verifies unit operation. This display allows a Pretrip Test to be
selected and initiated by the operator. If the Pretrip Test is entered with the
unit shut down, a Full Pretrip Test with device amp checks will be performed.
If the Pretrip Test is entered with the unit running in either diesel or electric
mode, a Running Pretrip Test is performed, but the device amps checks are
not performed. Test results are reported as PASS, CHECK, or FAIL when the
Pretrip Test is completed. If an alarm occurs during a Pretrip Test, the alarm
code will be displayed as Pretrip Alarm XX, where XX is the alarm code.
Pretrip Test Conditions
• Current unit settings are saved and restored at the end of the Pretrip Test
or if the unit is turned off and back on.
• Pretrip Test can be run in either Diesel or Electric Mode.
• The unit will auto switch from Diesel to Electric Mode or from Electric to
Diesel Mode during a Pretrip Test if these features are enabled and the
auto-switch conditions occur.
Conditions where Pretrip Tests are Not Allowed
• If any Shutdown Alarms are present. Pretrip tests are allowed with some
Check and Log Alarms.
