2.79 FUNCTIONS AT CUTBACK - POWER MODULE CURRENT LIMIT

Distress Lamp: 4
The Power Module is approaching its thermal limit and must reduce output to continue operation. The Power Module LED is
Flashing 8 - Controller Hot.
ELECTRIC POWERED MACHINES ONLY
All Functions Operable, but output from power module is at reduced power
Possible Causes: 4.1.1, 4.1.39, 4.1.12

2.80 FUNCTIONS LOCKED OUT - CONSTANT DATA VERSION IMPROPER

Distress Lamp: 9
Ground Module detected that the Application's Constant Data Version did not match the version embedded in Constant
Data's Flash Structure. The control system may resume operation once the difficulty has been corrected

Level Down, Front Left O/R, Front Right O/R, Rear Left O/R, Rear Right O/R, Set (Extend O/R), Stow (Retract O/R), Engine
Start, Engine Throttle Pull, Engine Throttle Hold, Engine Choke Pull, Engine Choke Hold
Possible Causes: 4.1.10

2.81 FUNCTIONS LOCKED OUT - PLATFORM MODULE SOFTWARE VERSION IMPROPER

Distress Lamp: 9
The Platform Module reported a Software Major Version that was not compatible with the rest of the system. The control sys-
tem may resume operation once the difficulty has been corrected.
