Explanation

The sensor is detecting that the Bridge Beam has not been lowered enough for operating in Over Companion mode.

Causes

• Bridge Beam angle sensor is faulty or requires adjustment
• Wiring fault
• Outer Leg foot is too far above ground (e.g. dunnage support may be too large)

Operator Actions

• Use override code to continue operation if Bridge Beam appears to be horizontal and Outer leg foot is placed correctly on ground.
• Request service

Service Tasks

• Bridge Beam angle sensor may need adjustment.
• If adjustment does not clear the fault then replace the sensor switch.
• If alarm is present when the Outer Leg foot is NOT on the ground then check if Over Companion sensor is working correctly.
