7.5 CONNECTION OF A REVERSING EDGE DEVICE
IMPORTANT NOTE
IF THE DOOR IS CONTROLLED BY ANY DEVICE OTHER THAN A CONSTANT PRESSURE PUSH-BUTTON
STATION, A REVERSING EDGE MUST BE CONNECTED.
CAUTION: CONNECT REVERSING DEVICE APPROPRIATE TO INSTALLATION.
Connection and installation of a reversing edge device is provided with the edge (Figure 18 and Figure 19). Any such
device that uses a normally open contact may be connected to terminals
#3 and #5 on the low voltage terminal block.
When the door comes in contact with an object during downward travel, the circuit will cause the motor to reverse the
door to the fully open position. In addition, there is a cut-off limit switch (
advance close limit switch) that will de-activate
the reversing edge during the last few inches of the door's downward travel.

7.6 DOOR LOCK SENSOR & FRICTION CLUTCH
Please read carefully prior to installing this operator
Operators supplied with an electronic
control board are equipped with the “DOOR LOCK SENSOR” feature.
The DOOR LOCK SENSOR prevents any damage to the
door when the door lock hasn’t been removed prior to
electronic operation. It eliminates the need of expensive
external interlock wiring.
This feature can only be used on operators equipped
with a FRICTION CLUTCH.
When the lock stops the door, the clutch slips and in less than
1 second, the door will reverse a fraction of a second to
release the lock.
WARNING
IF A CLUTCH IS USED IT SHOULD BE ADJUSTED ON SITE ONCE THE OPERATOR IS MOUNTED.
IN ORDER NOT TO DAMAGE THE DOOR WHEN THE LOCK IS ON, THE FRICTION CLUTCH HAS TO BE
ADJUSTED PROPERLY ACCORDING TO THE INSTRUCTIONS ON PAGE 12
