WIRE ROPE REPLACEMENT INSTRUCTIONS
Removal of Existing Wire Rope:
1. Make sure the replacement rope is same length as rope currently on actuator unit.
A. Ensure there is no load on handle, weighted load hook (pendant) or end effector.
B. If using slow down setting, clear (reset) on handle or pendant handle menu screen. If using virtual
limits, clear (reset) on handle or the pendant handle’s menu screen.
C. Remove end tool.
a. Slide handle: Using a 24mm socket and ratchet, remove the nut from the handle’s socket head
shoulder screw, then use an M8 hex wrench and remove (unthread) socket head shoulder
screw from handle. This will detach it from wire rope thimble. Set handle down on bench or
table to support it and not stretch coil cord.
b. Pendant handle: Remove the weighted hook or end effector
from rope removing the clip and pin and set aside.
2. Using a 3mm hex wrench, completely remove the four button head
screws on front cover.
3. Remove front cover from actuator and set aside upward to use as a
bowl to hold future parts.
Note:
Be careful not to contact circuit
board.
4. Going in the down direction, unspool rope from drum using jog down
button while keeping tension on wire rope with other hand wearing a
glove. Continue until lower limit is engaged.
5. Insert a medium sized screwdriver between the white colored wear
ring and the actuator black casting where the wire rope exits the
actuator (right side). This will keep the slack switch disengaged while
jogging down the remainder of the rope (
diagram M
).
6. Face the unit with circuit board on your left and wire rope on the
right.
Note:
The next two steps must be done at the same time.
7. Using a long screwdriver or hex wrench, reach through front of
actuator and locate upper socket head cap screw head facing you
underneath the lower limit switch. Fully push the screw in until it
cannot move anymore (it is spring loaded). Keep pressure on it
(
diagram N
).
8. Using your right hand, press the jog down button while watching the
drum rotate two full turns in the clockwise direction. The drum should
stop automatically with the wire rope retainer visible at the 3 o’clock
position on the drum.
WARNING
Wire rope replacement is to be performed by qualified maintenance personnel only.
