INSTALLATION
WIRING THE CABLE TENSION MONITOR
TIP: Wire both cable tension monitor bell wire pairs together using wire
nuts and run a single bell wire pair to the controller, per step 6. (polarity is
not important).
1. Route the cable tension monitor wires through conduit to the right lower
knockout on the junction box. (Use 1/2" or 3/4" conduit.)
2. The cable tension monitor wires will pass through the junction box and
through the conduit leading to the door controller.
3. See the door controller wiring for further cable tension monitor
instructions.

THE CABLE TENSION MONITORS MUST BE CONNECTED AND
PROPERLY INSTALLED BEFORE THE DOOR OPERATOR WILL
MOVE IN THE DOWN DIRECTION.
THE CABLE TENSION MONITOR DETECTS ANY SLACK THAT
MAY OCCUR IN THE CABLES AND WILL REVERSE THE DOOR,
ELIMINATING SERVICE CALLS.

The position of
the cable
tension monitor
will vary
depending on
the type of door
and drum used.
1. Make sure the door cable is approximately 3/4"-1" (19-20 mm)
from the mounting surface. Door adjustments or shimming may be
required to achieve proper depth for the door cable. The bracket must
be flush with the mounting surface
2. Position the cable tension monitor as close to the drum as possible.
The optimal distance of the cable from the wall surface is no more
than 2.5" (6.35 cm), and be sure the roller extends 1/8"-1/4" past the
cable. Make sure the cable tension monitor and roller is free from any
obstructions in all positions of operation..
NOTE: There must be no obstructions in the installation area that
prevent the cable tension monitor from closing completely when slack
is detected.
3. Use appropriate fasteners to fit a .282 clearance hole Anchor to wall.
(Fasteners not included)
4. Attach the cable tension monitor to the wall using the hardware
provided. Make sure that the roller is on top of the cable.
5. Run bell wire to the door operator junction box, and down to the
control box through conduit. See page XX for more details.
6. Connect the bell wires in parallel to the cable tension monitor
terminals on the controller. (polarity is not important) See below for
detailed controller wiring instructions.
NOTE: Cable must have tension through entire door travel. Make
sure there is no slack in cable on opposite side of door during
normal operation. If slack occurs during door travel, adjust cables as
required.
A second cable tension monitor may be installed for additional security.
When two cable tension monitors are installed, the door will not move in
the down direction or will reverse if one of the monitors detects slack or
is disconnected. If a second cable tension monitor is installed, the leads
must be wired in parallel. If one of the cable tension monitors is removed,
unplug both monitors from the operator, then plug in the monitor you
wish to use. Unplug and plug in the operator three times to relearn the
monitor to the operator.
