Level Sensor
INTRODUCTION
The Level Sensor has three wires: red-power (24 v in),
black-ground, white-output (24 v out). To verify that the
sensor is working properly, there is one LED under the
sensor that indicates the sensor is off level.
ADJUSTMENT
1. Place the machine on a firm level surface ± ¼°.
2. Use the Inclinometer (P/N: 010119-000) to ensure front
and rear of chassis is level ± ¼°.
3. Adjust the three leveling locknuts until the bubble is
centered in the circle on the attached bubble level.
TEST
Raise the platform approximately 7 feet, then push the level sensor to the side. The red LED should turn
on, and the tilt alarm should sound.
