My InteliLite MRS10 cranks once and goes off then a warning of maintenance comes on the screen

3 comments:

Mr. Anderson

The ComAp InteliLite MRS10 shows a maintenance warning because the Maintenance Timer 3 setpoint has reached zero. This timer counts down while the engine is running, and when it reaches zero, the warning alarm Wrn Maintenance 3 is issued. The warning remains in the alarm list even if the controller is restarted until the setpoint is adjusted to a positive value.
