When the configured stop conditions exist, the panel reduces the engine speed per the throttle profile and stops the
engine. If the configured start conditions exist before the shutdown process is complete the engine will return to the
previous speed until the stop condition exists.
Automatic Start/Stop Warning! When the key is turned to the autostart position and
a start condition exists, the panel will start
immediately ! Always configure parameters
by turning the key to run. Do not configure the panel in the autostart position! Always use lock out/tag
out procedures when servicing autostart equipment!
