Operation and Use
This product has been designed to warn mobile machinery operators that their machine is operating on a
dangerous incline. If the machine exceeds the maximum allowable incline (set to approximately 35degrees ±
10 degrees in all directions) the operator will be alerted via audible and visual warning for a preset time. This
warning period is switch selectable between 5, 6, 15, and 25 seconds. After a further seven seconds, the
engine will be shut down.
Note
If you wish to skip the shutdown sequence, and shutdown instantly when the key is turned off, connect the red
wire, from pin 1, to the ignition terminal (parallel to the orange from pin 2).
Override Operation
The system has an override switch incorporated to enable the operator to override the system once the engine
has shut down due to an over-inclined state.
Installation Guide
1. Mount the controller in suitable location in or near the cabin.
2. The unit MUST BE INSTALLED WITH THE LID FACING DOWN in the horizontal position and with the
machine parked on level ground.
3. Run and secure the wiring along existing looms to the controller. Mount the audible warning alarm in a
suitable position on the instrument panel. The override switch is optional. If used, it must be easily
accessible to the operator.
Wiring Connections
No.
