TEST DOWN FORCE REVERSAL
Place
a 1 1/2”(38) high object (or a 2X4 laid flat) on the floor, in
line with the door opener. When the closing door contacts the
object, it should stop, reverse, and automatically return to the
open position. If the door does not reverse, reset the down travel
limit so that the door travels slightly further down in the closed
direction. Then, retest the unit as described above. See Figure 32.
Open and close door twice before beginning test.
NOTE: Rail assembly may require center support to ceiling.
WARNING!
If the door does not reverse, disconnect your
opener and call a trained Martin Door Dealer.
TEST DOWN CYCLE PHOTO EYES REVERSAL
Photo eyes
must be clean and properly aligned. Loosen wing nuts
to rotate photo eyes vertically or horizontally for correct alignment.
See Figure 33.
The
green light on the transmitter photo eye and the red light on the
receiver photo eye must illuminate or the door will not close.
See Figure 34
Start
the door in the downward direction. Interrupt the invisible beam by waving a
solid object between the photo eyes. The Door Must Reverse! See Figure 35
Faulty
photo eyes can be bypassed with constant pressure on a wall control/push
button or transmitter button.
NOTE: To test the Up Force, place an object to stop the door in its upward direction.
The opener should stop when the door contacts the object.
The Martin
Opener
also has a third reversal protection system, which automatically
opens the door in 30 seconds if Opener Reversal System fails or if the door
is unable to completely close in 30 seconds time.

APPLY LABELS TO INSIDE OF GARAGE
TM
Martin
Finger Shield Garage Door and Opener Systems include a maintenance and
warning label on a packet fastened to the backside of the #3 door section. Inside the
packet are the owner’s garage door and opener instruction manuals. See Figure 32
Important
safety and instruction labels are included with your opener package. These
labels and the Instruction Manual must be fastened inside your garage where they can
be easily seen by all. We recommend fastening them next to the wall control. To fasten
labels, peel off the protective backing, and press onto smooth, clean surface. Tacks or
additional adhesive may be necessary. DO NOT PAINT OVER ANY LABELS.
