5.2 System Maintenance

The ACM monitors time between periodic maintenance of the engine-generator. The Service

Interval internal ACM variable represents the number of hours of engine-run-time between

periodic services. When the engine runs for a number of hours equal to Service Interval, the

ACM sets the Service Required Alarm and turns on the amber notiﬁ cation LED. The default

value of Service Interval is 100 hours. Pressing and holding the service-reset switch for 5

seconds resets the service counter and Service Due is updated with the current value of the

service interval.

Oil change exact times will vary as a function of temperature and operating conditions.
