Check the connector block that plugs into the sensor card for loose wires. Finally, it is possible that the ring terminal
that connects the sensor to the handle itself has come loose. See Figure 2.
If you can hear this click (or see the LED come on)
and the door does not release, try the backup switch. If the
door still doesn't release, the problem must be in the installation wiring as it is nearly impossible to have a failed
sensor relay and backup switch at the same time. Review your wiring to make sure the sensor is correctly applied in
the circuit. If you hear the click but only the backup switch releases the door, call the factory as the defect appears to
be in the relay contacts and the sensor will have to be replaced.
PROBLEM-
The door remains released constantly
If you hear a click
when you touch the handle but the lock remains released, the problem is probably in the wiring
which should be reviewed to be sure the sensor is correctly applied in the circuit. Note that you can monitor the LED
which comes on when the handle senses touch if you remove the plaque.
If the LED is on constantly or if you
don't hear a click when you touch the handle
, the sensor is probably adjusted too high (review section 3.6).
Rotate the adjustment pot counter-clockwise
while not touching the handle
. If this doesn't lock the door, some
effect is probably keeping the relay deenergized all the time (remember; the relay is energized when the lock is
secure to maintain fail safe operation).
The most likely cause for the relay to remain deenergized is that the sensor "sees" an overwhelmingly large signal as
if someone was continually touching the handle. This will happen if the handle is not properly isolated from a metal
door. Because of the plastic base, the intrinsic isolation of the handle from the door is many times greater than it
needs to be. Make sure that there is no "foreign object" creating a conductive path from the handle to the door. An
example would be metal blinds.
The same effect will occur if the handle is used outside in the rain or if water is flowing down the inside of the door.
This overcomes the electrical isolation needed between the handle and door.
Certain large electronic noise sources can "swamp" the sensor although this is rare. Examples would include large
radio or radar transmitters in the building or a high voltage neon sign mounted within a few feet of the door. Call the
factory if you suspect noise induced problems.
Finally, in very rare instances, the sensor can “hang up” in a condition that continuously releases the door. De-
power the unit and turn the adjustment pot all the way counterclockwise. Then, re-power the unit and note that the
door locks. Then, readjust the sensor potentiometer normally.
