Miller Edge MEL-K20 User manual

2-1. Open and unpack the antenna, batteries, transmitter
and receiver units.
2-2. Loosen screws from the top cover and remove the lid.
2-3. Remove the Transmitter PCB by pulling upward on one
of the silicone caps.
2-4. Route the wires from the monitored edge through
the strain relief cable fitting for approximately four inches.
Strip the insulation from the two wires back ¼” and secure
the wires in the terminal block marked SE 1. (Not olarized.)
A Knockout (K.O.) switch may be wired to the Tx terminal
strip marked KO. (Either normally o en or normally closed
switches may be used.)
2-5. Place the two AA Lithium batteries in their holders in the
proper direction, paying attention to the (+) and (-) ends.
2-6. Tuck the wires connected to the SE terminal block neatly
between the batteries and pull the excess wire back
through the strain relief.
Re-seat the PCB in the case, and securely tighten the
cable fitting.
2-7. Set the Termination Type switch to either 10K or DC.
(see Appendix) This selection must match the
Termination Type in the Safety Edge.
2-8. Address Switches
Set the Group (red) and Address (blue) switches to the
desired position. (Note the settings for reference when
setting up the Receiver.)
If the Group switch is set to 0, the Address switch may be
set to any position between 0 and F.
If the Group switch is set to 1, the Address switch may be
set to any position between 0 and B.
(The remaining ositions, C, D, E, and F are reserved for
factory test.)

2- Install Transmitter and Test
The Monitored Edge Link (MEL) transmitter/receiver system is intended to provide a wireless connection between
a monitored safety edge and a motorized operator that controls the associated door or gate. MEL meets the
UL-325/2010 requirements for monitored devices and has been certified as a UL325 recognized component.
It is designed for use on operators that comply with UL325-2010 using a T2 or T3 terminated edge sensor.
Required:
1. 1/8” Flat blade screwdriver
2. 1/4” Flat blade screwdriver
3. T2 (10K/Blue Band) or T3 (Diode-
Capacitor/Red Band)Terminated Sensing Edge

2-9. Momentarily press the TEST button. The Green Tx Data LED should flash.
(The Red Low Battery LED will only light when the batteries fall below 2.4v.)
2-10. Mount the Transmitter to the door or gate using #6 - 20 x 3/4” self-drilling screws.The mounting holes are
located under the Top Lid Screws. Mount the transmitter with the wire strain relief facing down or to the side.
2-11. Replace the cover on the Transmitter and tighten the screws taking care to align the lid.
*Note the alignment in located in the u er left corner.
3- Install Receiver and Test
3-1. Remove lid of the Receiver Unit.
3-2. Set the Group (red) and Address (blue) switches to
match the transmitter settings.
3-3. Mount the receiver close to the operator and in-the-line-of-sight
of the transmitter using the mounting holes, as shown.
3-4. *Connect the receiver’s PE (Photo-Eye) output to the operator’s
PE input terminals using Green and White wires.
(Operator terminal label naming may differ. Contact factory for
support).
3-5. Connect the Black and Red wires to a 12 or 24V ac/dc source.
3-6. Attach the antenna to the receiver RF board.
3-7. Prel m nary Test :
Confirm that the Transmitter and Receiver are powered ON.
Activate the Safety Edge (or monitored device).
The Address Valid Yellow LED on the Receiver should
flash momentarily.
If the Address Valid LED does not flash, check that the
Group and Address switches match the transmitter
settings. Confirm that the Photo-Eye and Safety Edge
LEDs are lit while the safety edge is held active.
Note that the Photo-Eye and Safety Edge LEDs
go OFF when the Edge is released.
3-8. Replace the Receiver Lid taking care to slip
the Antenna through the lids’ grommet.
*Certain installations may require an alternative wiring
scheme. Please consult factory for assistance.
4- Safety Test
4-1. While moving the door in the downward direction
or the gate in the desired direction, momentarily
activate the Safety Edge and confirm that the
door or gate stops and reverses direction.
