Installation Instructions
TRANSMITTER INSTALLATION:
1- Remove lid from top of the MWCT04 Transmitter to reveal mounting holes.
Position the Transmitter near the bottom of the door and mark the mounting
hole locations.
2. Remove the Transmitter from door, drill holes and mount the Transmitter with
screws supplied. NOTE: DO
Only use holes in the 4 corners of the box. Any additional holes in the transmitter
box will cause water to enter and a loss of warranty.
3- Loosen wirefitting nut and feed the 2 or 4 wire sensingedge leads into theTransmitter housing trimming offexcess wire.
4- Attach the 4-lead wires to the large green two-part terminal block connector as White, White, Black, Black. If a 2-lead wire
connection is appropriate, connect them to the middle terminals, i.e. none,White, Black, none.Tighten the wire fitting nut
to assure water tight connection.
5- Adjust Dip Switches: 1= Address Selector 2= Address Selector 3= Address Selector 4= Address Selector
5= OFF for 4-wire edges, ON for 2-wire 10KΩ terminal edges 6= Edge Input ON=N/O OFF= N/C 7= Always OFF
8= OFF for Normal Operations, ON for Test Mode (transmitteralways “ON”)
NOTE:thefour DIP address switches must be setidentically on the transmitter and receiver.
NOT drill any holes in the transmitter box.

6- Be sure that the battery strap is connected and insert 9 Volt battery into the lid of the unit, and replace the lid.
The Green LED light should light up briefly, indicating that the unit is functioning properly.
WARNING!
TO REDUCE RISK OF SEVERE INJURY OR DEATH; READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS
TO PREVENT ELECTROCUTION: DISCONNECT POWER AT FUSE BOX OR CIRCUIT BREAKER AND DOOR OPENER BEFORE WIRING PERMANENTLY.
IMPROPER WIRING COULD CAUSE ELECTROCUTION OR DAMAGE TO CIRCUITRY.FOLLOW ALL LOCAL BUILDING CODES AND NATIONAL ELECTRICAL CODES.
RECEIVER INSTALLATION:
1- Hold the MWCR04 Receiver in the mounting position near the operator: mark and drill mounting holes.
2- Attach a 24VAC (at least 100mA) source to the Red & Black wires. A 24 VDC source may also be used with Red to positive
(+) and Black to negative (-). When using 24 VAC, check to see if one
leg is connected to the operator case. If connected to the case, connect
that leg to the Black wire of the receiver.
3- Connect the Whitewires to the Safety Edge input forthe motor operator.
The output relays will bear a resistive load of 1A at 24VAC.
The state of the relay is shown with a Yellow LED. The LED is
illuminated when the channel is in a SAFE operating condition
and will go out under fault condition. Relay contacts can
be selected N/O or N/C by moving jumpers (shunts)
inside the enclosure.
4- Adjust Dip Switches: 1= Address Selector 2= Address Selector
3= Address Selector 4= Address Selector 5= OFF for Standard
operation (all faults and safety edge activity activate the operator’s
safety edge input)
5- Mount the Receiver near the operator using the 2 screws supplied.
Take care to make sure the rigid wire antenna completely extends past
any metal of the operator enclosure.

NORMAL START-UP SEQUENCE
- On Power Up, the receiver performs a light-test for 1/2 second ”ON” and 1/2 second “OFF” and then begins normal operations.
1
When the battery is connected to the transmitter, it also lights it’s Green (Activity) LED for 1/2 second “ON” and 1/2 second “OFF”
and then begins normal operations.
2- Apply power to receiver; the Green (POWER ON) LED should come on with one Yellow (SAFETY EDGE, RELAY 1) LED, near
antenna end of the receiver.
3- Press (activate) the Safety Edge; the Green TransmitterLED shouldblink “ON” briefly, and the receiver’s Green (Signal Acquired) LED should
also blink “ON”. The Yellow (Safety Edge Active) LED should light and stay lighted for as long as the Safety Edge is activated,and go “OFF”
when the Safety Edge is released. If there are no faults sensed, the Red (Maintenance Required)LED will remain “OFF”.
4- When the Safety Edge is pressed, the receiver’s Yellow (Safety Edge, Relay1) LED will go “OFF” and the Yellow (Safety Edge Active) LED
will go “ON”.
5- If the Safety Edge is pressed for longer than 1/4 second while the door is closing, the door should stop and reverse.
6- If the Red (Maintenance Required) LED comes on during door operation at any time, a fault is indicated. Slow blinking indicates that
a weak battery is sensed in the transmitter. Fast blinking indicates that a wiring fault to the Safety Edge is sensed. Solid “ON” indicates
that the receiver has not heard from the transmitter in over 10 minutes.
TROUBLE SHOOTING HINTS
1- The receiver’s Green (Power-On)LED is not illuminated:
a) Checkwith a VOM to see if 24 voltsAC or DC is present at the receiver.
b) If using DC power, check to make sure Red is positive and Black is negative.
2- The Transmitter’s Green LED never comes on:
a) Check to make sure the batteryis connectedand check battery voltage(shouldbe 8.2 voltsor higher).
b) Remember: the transmitter only comes on briefly when the sensing edge is pressed or released, and once every 5 minutes if
there is no other activity.
3- The Transmitter’sGreenLED comes on, but not the receiver’sGreen (Signal Acquired)LED comeson - Check address DIP switches, they
must be set indentically.
If they are identical, symptom could be a result of low RF signal strength. Check antenna location: should be outside of any
metal enclosure(s), and pointing away from the operator case.
4- The receiver’s Red (Maintenance Required) LED is on:
a) Slowly Blinking; Verify battery voltage. It should be 8.2 volts or higher, if not replace with same type (Lithium 9 Volts).
b) Fast Blinking; Check the wires to the safety edge: One is not being sensed as connected.
c) Solid; Receiver has not heard from the transmitter within last 10 minutes. Press the sensing edge at least once to send a
message and clear the fault..
5- The receiver’s Yellow (Safety Edge, Relay 1) LED is not illuminated, Green (Signal Acquired) LED illuminates, Edge tested good,
door/gate always goes to fault location.
a) Check edge wire connections to make sure the colors are correct and that bare wire is contacted inside the terminal block.
b) Check for wire short circuit between the Black sensing edge wires and the White sensing edge wires.
