PRETRIP TEST Key
Pressing and holding the PRETRIP TEST Key for 5 seconds will initiate either a Full Pretrip Test or
Engine Running Pretrip Test so long as no alarm conditions exist. If the Alarm Icon is glowing, record
and clear the alarms before starting the Pretrip Test.
Press and hold the PRETRIP TEST Key for 5 seconds. If the unit is not running when the PRETRIP
TEST Key is pressed the unit will perform a Full Pretrip that includes circuit amps and running system
checks. If the unit is running when the PRETRIP TEST Key is pressed the unit will perform the
running system checks only. The amber LED may flash while the Pretrip Test is initialized and will
glow steady while the Pretrip Test is running. When the Pretrip Test is complete the amber LED will
turn off.
• If there are no alarm codes set when the Pretrip Test is complete, the unit passed.
• If there are alarm codes set when the Pretrip Test is complete, the unit failed. Check and correct the
alarm conditions and repeat the test.
• If a shutdown alarm occurred, Alarm Code 28 Pretrip Abort will be set and the unit will be shut
down. Check and correct the alarm conditions and repeat the test.
Secondary Use - When the unit is turned off press and hold this key for 5 seconds to show the HMI
Control Panel Serial Number (in the upper display) and the HMI Control Panel Software Revision (in
the lower display).
