During normal operation, the six-up display will be viewed.
When the diagnostic gauge receives a severe trouble code from an ECM, the six-up display will be
replaced with the “Shutdown” message, The SPN and FMI number will be displayed along with a description of
the problem.
To acknowledge and hide the trouble code and return to the six-up display, press the “E” key.
The gauge will return to six-up display, but the display will contain the “Shutdown” icon. See section
3.5.10 for accessing “Active Faults” to display the shutdown code again.
The six-up display screen will contain the shutdown icon until the trouble code condition is corrected.
For Clarke engines, the only shutdown condition is engine overspeed. See Section 8.3 for overspeed reset.
The engine will not restart and run until the overspeed reset procedure is performed.
Weekly Test
An experienced operator should always be present during the weekly test.
NOTE: This engine is designed to operate at rated load conditions. For testing purposes, the engine can be
run at lower load (lower flow) conditions. Running times in any one period should not exceed 30 minutes
maximum.
Before starting the engine make sure of the following:
The operator has free access to stop the engine in an emergency.

All the guards are in position and, if not, for whatever reason, any rotating parts will be free and clear without
restriction.
Battery covers are in place and there is nothing on top of or touching the engine, which is not part of the
original supply specification.
Heat Exchanger Cooling: The water supply for coolant is available again without restriction.
Radiator Cooling: The air supply for cooling is available again without restriction.
When engine is running make sure of the following are within the limits specified on the relevant Installation &
Operation Data Sheet in the Technical Catalog.
