to ensure the switches operate properly.
2.5.1
Attaching the Anti-Two-Block (ATB) Cable and
Extension Sensor Zero
Ensure the extension sensor clutch is properly set for “0”, and the spring is properly pre
- tensioned by
following this procedure:
1. Fully retract the boom assembly and remove the reeling drum cover.
2. Slowly rotate the reeling drum clock
wise until a “click” is heard, indicating that the power spring
clutch is engaged.
3. Turn the reeling drum counterclockwise five (5) complete turns and physically restrain it from
moving.
4. Remove enough cable from the drum (three wraps = 10 feet) to reach the boom tip, leaving
enough extra cable to reach the Anti-Two-Block hardwire.
5. Install a strain relief on the cable.
6. Pull the extension potentiometer downward against the tension spring enough to rotate the gear
clockwise. Continue until the potentiometer reaches the end of the travel and the clutch drags.
7. Pre-tensioning of the reeling drum is complete, and the extension sensor is properly set for
calibration.
