1. Loosen the 3 Allen set screws using an Allen key AF3 (for 4mm ropes) or AF4 (for 6 mm
ropes). Note: The set screws have got a clamping coating in order to prevent accidental
loosening. Thus an increased torque might be necessary to loosen them.
2. Remove released rope from the weight.
3. Measure off new rope length.
4. Wrap adhesive tape around the rope at the point to be shortened to prevent it from fanning
out.
5. Saw off the rope at a right angle or cut it off with a bolt cutter.
6. Insert the rope completely into the weight: rope 4 mm (0.16 in): 60 mm (2.4 in) deep; rope
6 mm (0.24 in): 80 mm (3.2 in) deep.
7. Screw the set screws into place. Due to the clamping coating of the setscrews application of
a screw locking fluid is not necessary. Torque: rope 4 mm (0.16 in): 5 Nm (3.7 lbf ft); rope
6 mm (0.24 in): 15 Nm (11 lbf ft).
Shortening coax probes
Coax probes must be shortened if the distance to the container floor or outlet cone is less than
10 mm (0.4 in).
Coax probes can be shortened max. 80 mm (3.2 in) from the end. They have centering units
inside, which fix the rod centrally in the pipe. The centerings are held with borders on the
rod. Shortening is possible up to approx. 10 mm (0.4 in) below the centering unit.
The coax probe is shortened by sawing the pipe at the bottom end.
