Manual Hand Chain and Disconnect Chain
6.1
Installation
6.1.1
Chain Hoist (Opera-H / SH / HJ)
Before pulling the hand chain through the pocket wheel, pull the limit
cam's retaining bracket back. Turn the cams to the center of the limit
shaft to be sure that they are not being mechanically driven through
their normal limit switch end positions.
1. Run the hand chain through the pocket wheel and through
the chain guide, see Figure 11.
2. Allow both ends of the chain to hang down toward the
ground until both ends are approximately 2 feet (0.6 m) from
the floor. Cut the hand chain if necessary.
3. Connect both ends of the hand chain together.
6.1.2
Disconnect Chain (Opera-J / SH)
1. Link the disconnect chain to the hook located at the
extremity of the operator's disconnect mechanism, see
Figure 12.
2. Install the handle under the chain keeper to facilitate
handling of the chain.
3. Under the handle, make a knot in order to fasten the end of
the chain.
6.1.3
Emergency Egress (Opera-HJ)
This operator is built to receive a quick disconnect in case of an
emergency egress.
1. Pass the cable housing (from the emergency egress
control) through the holes provided on the frame of the
operator, see Figure 13.
2. Attach the end of the egress cable to the disconnect lever.
3. Secure positioning of the cable housing with two adjustment
collars.
