For a BRIEF TEST, turn on the transmitter's test mode switch, #8, and activate the safety edge to
TO TEST FOR A RF SHORT-RANGE PROBLEM BETWEEN THE TRANSMITTER AND THE RECEIVER:
initiate a transmission. The transmitter will come on and stay on until the switch #8 is turned back
off for normal operation. The receiver Signal Acquired green LED (next to the red Maintenance
Required LED) should come on and stay on while the door is run through its range of motion. The
safety edge should work as usual while in test mode. TURN OFF "TEST MODE" AS SOON AS
POSSIBLE, to avoid undue RF interference and also quickly exhausting the transmitter battery.
An ACTIVE SENSING EDGE to the transmitter will cause the receiver sensing edge output relay
REMEMBER:
to stay ACTIVE.
ALL FAULT CONDITIONS (low battery, edge termination not sensed, communications time-out)
cause the receiver to put the door-operator into Constant Pressure mode.
Check the condition of the receiver's indicator lights at the time of the problem, to quickly
find the cause.
Some locations are much more electrically noisy than others. If the receiver shows signs of
performing a "power-on" light test when the operator's motor starts or stops, or other heavy
equipment in the vicinity seems to be affecting the wireless link, please contact Miller Edge
with the necessary information (mounting location, plus the make and model of the door
operator or other related equipment) to resolve the problem.
