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.
