Main Winch lockout near bottom.

System

Safety / Interlock

Symptom

Main Winch lockout near bottom.

Diagnosis & fix steps

LOGIC: Safety interlock thinks the tool is already grounded when it isn't. ACTION: Disconnect the proximity switch and see if the "High" signal clears. If it does, the sensor is "Shorting Internal" and must be replaced.

Red Seal field insights

Specs: Normally Open (NO) logic. PRO-TIP: In piling, the "Whisker Switch" (Mechanical) is older tech. The LB30 almost exclusively uses Inductive Proximity Switches which are more robust against mud but fail if the bracket vibrates loose.
