SETTING THE EXERCISER
Press and hold (5 seconds) the Set Engine Exerciser button. The
exercise period occurs immediately and at the same time weekly

start and run), the exerciser must be reset after the power is restored.
The ASCO 185 has settings that can be changed for various
applications. The dipswitch options are explained in the ASCO 185
Operator’s Manual.
This completes your installation and unit testing. ALWAYS leave the
system in automatic mode unless servicing the unit. For automatic
operation, the auto mode icon must be displayed on the engine control
module display.
