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 17). 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
All 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
IN ORDER NOT TO DAMAGE THE DOOR WHEN THE LOCK IS ON, THE FRICTION CLUTCH HAS TO BE
ADJUSTED PROPERLY ACCORDING TO THE INSTRUCTIONS PROVIDED ON PAGE 11
