Step 1: Mount contact switch on door according to
enclosed directions.
Step 2: Remove the common wire connection from the 11 pin
socket, located at the #1 position.
Step 3: Wire the BLACK wire from the contact switch to one of
the common termials on the terminal strip.
Step 4: Wire the RED wire from the contct switch to the #1
position on the 11 pin socket. The white wire is not used in this
setup.
Step 5: Test limit switch by closing the door, when the door is

of either photo-eye.
The Door should continue down and close.
If the door reverses, check connections and repeat the process.
