SETTING THE EXERCISER

Press and hold (5 seconds) the Set Engine Exerciser button. 

The exercise period occurs immediately and at the same 

time weekly thereafter. The status light below the button 

blinks during the exercise period (including cool down). The 

light stays on to indicate that the exerciser has been set. If 

the light is off, the exerciser has not been set.

CANCELING AN ACTIVE EXERCISE PERIOD 

Press the Bypass Time Delay button to stop an exercising 

generator. If exercise with load is set, the ATS retransfers the 

load to the utility, then stops the generator after cooldown.

WARNING

With a total power failure (utility power fails and the 

generator fails to start and run), the exerciser must be 

resest 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.
