1. INSTALLATION SETUP

1. All Miller Edge sensing edges are inspected and tested prior to shipment to ensure quality. Upon opening the shipping box, inspect your sensing
edge and wiring for shipping damage. If the shipping container appears to be damaged, please notify carrier immediately.

2. Un-box and lay the sensing edge out straight. This will allow the edge to relax and return to its original shape.

1. Slide the edge into the mounting channel.

2. Align the edge and mounting channel to the leading edge of the door.

3. Adjust the close limits on the motor for a maximum compression of
.25” (6 mm).

4. Attach the channel to the by drilling self-tapping screws into the
mounting channel, starting 3” (7 cm) from the ends and spaced
approximately every 24”.

TECH TIP

To compensate for floor irregularities, gently curve the mounting channel
up or down to close any gaps between the edge and the floor, wall, or
other permanent fixture.

2B. MOUNTING CHANNEL INSTALLATION (OTHER)

1. Attach the channel to the by drilling self-tapping screws into the
mounting channel, starting 3” (7 cm) from the ends and spaced
approximately every 24”.

2. Slide the edge into the mounting channel.

3. Adjust the close limits on the motor for a maximum compression
of .25” (6 mm).

3. SENSING EDGE INSTALLATION

ME123 SENSING EDGE

WIRELESS METHOD

COIL CORD METHOD

Note: For specific operator input connection diagrams

and instructions, please consult your operator manual.

REQUIRED

Miller Edge wireless edge transmitter/receiver system

INSTALLATION

1. Consult the Miller Edge transmitter/receiver installation
instructions for wiring of the sensing edge.

2. For proper connection to operator inputs, please consult
the operator manual.

REQUIRED

Junction boxes (2) Mounting screws
Wire end caps 18-22 gauge wire

INSTALLATION

1. Mount the first junction box on the end stile or bottom bar
of the door.

2. Run the sensing edge lead wire into the junction box.

3. Mount the second junction box on an adjoining wall,
midway between the floor and the operator.

4. With the door in the closed position, secure the coil cord
to the first junction box.

5. Then run it, fully stretched, to the second wall mounted
junction box so the stretched length is equal to one-half of
the door opening.

6. Secure the coil cord into the wall junction box and trim the
coil cord. This assures the excess coil cord will not get
caught or hang in the opening of the door.

7. Secure 18-22 gauge wire into the second wall-mounted
junction box and hard wire to the operator sensing edge
terminals.

RETRACTING REEL METHOD

REQUIRED

Junction box (1) Mounting screws
Wire end caps 18-22 gauge wire

INSTALLATION

NOT SUITABLE FOR MONITORED SENSING EDGES

1. Mount the junction box on the end stile or bottom bar of
the door.

2. Run the sensing edge lead wire into the junction box.

3. Mount the retracting reel on an adjoining wall, near the
operator.

4. With the door in the closed position, secure the retracting
reel cable to the junction box. The cable should freely

and instructions, please consult your operator manual.

extend, without rubbing, in and out of the retracting reel for
the duration of the open/close cycle.

5. Using the 18-22 gauge wire, hardwire the retracting reel to
the sensing edge terminals of the operator.
