Controller Information Displays, Functions, and
Reset
The Power Zone™ controller constantly monitors vital
generator and engine functions for a number of
operation, alarm and fault conditions. When a fault
condition occurs, the engine will shut down automatically
and the main display will show the fault that has caused
the shutdown. To resume operation, the fault condition
must be resolved. To reset the controller and resume
operation, press the Enter () button.
Belt Tensioners
John Deere engines use two types of belt tensioners:
manual and automatic. Adjust the belt using the manual
tensioner according to the manufacturer’s specifications.
The automatic tensioner cannot be adjusted or repaired
and is designed to maintain proper tension over the belt’s
life. Units with the automatic belt tensioner must be
inspected according to the manufacturer’s specifications.
