STEP 13: CONFIGURE MCB FOR SAFE
FINISH OR ELECTRIC EDGE OPERATION
If you have not installed a Safe Finish Photosystem or
Electric Edge at this time proceed to Step 15 on Page 13.
In order for your Safe Finish Photosystem or Electric
Edge to work properly you must configure the motor
control board to work with these devices.
Make sure the power is disconnected from the operator
and remove the unit’s cover. Locate the motor control
board inside of the operator. Locate the Obstruction
Jumper on the Control Board using the diagram at right.
The Obstruction Jumper is a simple wire jumper located
close the center of the motor control board. The letters
“OBS” are silk-screened on the board just above the
jumper and the letters “SW2” are silk-screened on the
board just to the left the jumper.
With a small wire cutter cut this jumper in half and separate
the two halves so they do not touch.
The motor control board is now configured for Safe Finish Photosystem or an Electric Edge operation.
C: INSTALLING THE OPERATOR
STEP 14: ALIGNMENT AND INITIAL TEST OF SAFE FINISH PHOTOSYSTEM
AT THIS POINT PLUG CONNECT THE POWER TO THE OPERATOR.
A. Connect the power to the Garage Door Opener. Keep a portable transmitter with you to control the garage door opener. The red
light on the receiver unit should now be on. If not, recheck that the mounting screws are tight then, if necessary, align the
photosystem by slightly bending the wall bracket until proper operation is obtained.
B. Place an object (packing insert box or a similar object at least eight inches high) one foot in front of the transmitter or receiver.
The red LED should go OFF and remain OFF until the object is removed. NOTE: There may be a slight delay in returning to
normal depending upon how long the photosystem was blocked. If the light fails to go off when the object is placed in the path of
the beam check the wire connections and the installation height of the units (see Steps 11 and 12).
C. Move to the center of the door. Make sure the red LED light is on. Move a solid object slowly through the beam. The
LED should go OFF and then ON.
D. Using the pushbutton or transmitter, activate the opener and check that it will operate through the full open and close cycles. If
not, re-align the photosystem by slightly bending the wall bracket until proper operation is obtained.
E. Tighten all mounting screws and bolts, loop and secure any extra wire.
AT THIS POINT PLUG DISCONNECT (REMOVE) THE POWER TO THE OPERATOR.
