Controlled Products Systems Group MWCK04 - Manual (Page 2)

1- On Power Up, the receiver performs a light-test for 1/2 second ”ON” and 1/2 second “OFF” and then begins normal operations.
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 Transmitter LED should blink “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.
NORMAL START-UP SEQUENCE
1- The receiver’s Green (Power-On) LED is not illuminated:
a) Check with a VOM to see if 24 volts AC 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 battery is connected and check battery voltage (should be 8.2 volts or 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’s Green LED comes on, but not the receiver’s Green (Signal Acquired) LED comes on - 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.
