Signal Cable Assembly
The SIGNAL CABLE ASSEMBLY connects the reeling drum sensors, the Anti-Two-Block switch and
the system computer.
Removing the Reeling Drum from the Boom
1. Completely lower and retract the boom.
2. Disconnect the Reeling Drum Cable and the Anti-Two-Block switch.
3. Grip the Reeling Drum Cable firmly and remove it from the tie-off post.
4. Maintain a firm hold on the Reeling Drum Cable as it winds back onto the Reeling Drum.
5. Secure the end of the Reeling Drum cable to unwinding.
6. Disconnect the signal cable at the distal end.
7. Unbolt the Reeling Drum from the crane with a wrench.
Removing the Signal Cable from the Reeling Drum
1. Remove the cover from the Reeling Drum.
2. Remove the Slip-Ring on the sensor baseplate assembly.
3. Disconnect all wires from the sensor assembly except for the 6 wires leading to the Angle and
Extension sensor potentiometers.
4. To protect the sensors within the Reeling Drum, use two screws to temporarily attach the cover
of the Reeling Drum.
5. Turn over the Reeling Drum to expose the back of the device.
6. With the wires still disconnected, pull the Signal Cable out of the main shaft in the center of the
Reeling Drum. This cable has a strain-relief encircled with an O-ring which creates a tight fit to
prevent water intrusion.
NOTE:
If it is difficult to remove the cable, use the insertion/extraction tool from the front of the Reeling
Drum to release the cable.
Installing the Signal Cable
1. Ensure the O-ring on the strain-relief is greased.
2. With the back of the Reeling Drum exposed, insert the end of the Signal Cable with O-ring into
the mounting plate and down the shaft in the center of the reeling drum.
3. Ensure the strain-relief is properly seated with the O-ring using the tool provided in the kit.
4. Bend the cable to the side and position the hollow section of the tool on the strain-relief plug at
the top of the shaft.
5. With a hammer, gently tap the top of the tool forcing the strain-relief into the proper position in
the shaft. Continue to tap gently until the strain-relief pull will not go any farther in the hole.
6. Turn over the Reeling Drum and remove the cover.
7. Connect the wires to the terminal block as indicated by the Sensor Baseplate Diagram.
8. Tuck the unconnected remaining yellow and orange wires down into the shaft.
9. Connect the brown wire from the Slip-Ring Assembly to TB1-5, connect the black wire to TB1-6.
