READ AND UNDERSTAND ALL INSTRUCTIONS BEFORE BEGINNING INSTALLATION. The Miller Edge Model MWTA12 and MWT12 safety edge transmitters are designed to provide wireless signal transmission from the safety edge to the motor controls. The Model MWTA12 includes an Audible Alarm feature indicating the battery should be replaced. Both the Miller Edge receiver and transmitter have a compact design which allows for easy trouble shooting via the see-thru case. Selectable features include: coded dip switches and a wire harness for relay options. IMPORTANT:

1. 1/8 Flat blade screwdriver for wire connections 2. 1/4 Flat blade screwdriver for top lid screws Recommended:
DVM for test purposes
(4) #6 - 20 x 3/4 self-drilling screws, as required Sensing edge (sold separately) Install Transmitter and Test 2-1. Open and unpack the batteries, Transmitter and Receiver units. 2-2. Loosen Top Lid Screws on the Transmitter and remove lid. Remove the Receiver Top Lid by pressing one side of the snap lock base inward while lifting lid. TRANSMITTERENCLOSURE Shown with Optional Alarm TOPLID SCREWS 2-3. Set the 9 Pole, 3 Position Coding Switch on the Receiver to match the Transmitters 9 Pole, 3 Position Coding Switch. Any switch position will work as long as the Transmitter coding switch and the Receiver coding switch are exactly matched (must be different from other nearby transmitters of the same type). 9 POLE, 3 POSITION CODING SWITCH 2-4. Place the two (2) AA batteries in their holders on the Transmitter in the proper direction, paying attention to the (+) and (-) ends. Momentarily press the Test Button on the Transmitter. The Green Tx LED Indicator should light for 3 seconds. AA LITHIUM BATTERIES 2-5. Route the wires from the safety edge through the Transmitters Strain Relief Cable Fitting for approximately four inches. TEST BUTTON GREEN TX LED INDICATOR 2-6. Strip the insulation from the two wires back . Pull the Terminal Block off the Transmitters PCB. Place the safety edge wires in the Terminal Block and tighten with screwdriver. Re-seat the Terminal Block on the PCB (see Fig. 2-6). 2-7. Re-seat the PCB into the Transmitter Enclosure and securely tighten the Strain Relief Cable Fitting. 2-8. Now, compress your safety edge. The Green Tx LED Indicator should light for about 3 seconds. STRAINRELIEF CABLE FITTING

Install Transmitter and Test Cont. 2-9. The four (4) Pre-Drilled Corner Mounting Holes are located on the far corners of the Transmitter Enclosure. Mount the Transmitter to the gate post, door end stile, or bottom angle using (4)
#6 - 20 x 3/4 self-drilling screws. Mount the transmitter with the wire outlet facing down or to the side. 2-10. Replace the cover on the Transmitter and tighten the Top Lid Screws, taking care to align the lid. 3-
Install Receiver and Test 3-1. Mount Receiver inside the operator control box so that the wires from the receiver will reach the terminal strip on the operator. RECEIVERENCLOSURE 3-2. Wiring:
a. The red (+) and black (-) wires are your power leads. They connect to your operator panel terminals that provide the appropriate power (12-24 VAC/VDC). Black wire is common, Red wire is (+) or AC power. b. The green wire is your standard antenna wire. This must be located outside of any metal enclosure to provide for good signal reception. There is an F-Connector antenna fitting included on the receiver in the event a remote antenna placement is needed. c. Receiver Connections: The white wire will go to your operators low voltage common terminal. If your operator requires a normally open (N.O.) contact, connect the yellow wire to the operators safety edge input. If the operator requires a normally closed (N.C.) contact, connect the orange wire to the operators safety edge input. 3-3. Preliminary Test:
Confirm that once power is applied to the Receiver, its green LED is lit. Now press the Transmitter's test button and notice that the red LED lights up on the Receiver and the green LED lights up on the Transmitter. 3-4. Replace the Receiver Top Lid. 9 POLE, 3 POSITION CODING SWITCH LED INDICATORS F-CONNECTOR ANTENNA FITTING MOUNTING SCREW HOLES 4-
