1. Allow the door to open in the automatic
mode. Unlock the Presence Sensor and
launch a setup by pressing the Setup key,
followed by the number 2. If the sensor
does not begin flashing green, and instead
goes back to a red indication, improper data
exists. Refer to respective lockout User’s
Guide for troubleshooting.
2. Check for proper polarity at terminal 6 and
7. The negative wire from the lockout
(white) should be connected to terminal 6,
and the red/white striped wire from the
lockout should connect at terminal 7.
HELPFUL HINT: If faulty data is suspected,
simply power the door to the open position
(by activation OR with the use of a hold
open switch). While the door is open,
unlock the Presence Sensor, and press the
setup key, followed by the number 2. If the
sensor goes back to a red LED (as opposed
to flashing the green LED to indicate a
setup), there is a strong probability that the
data is incorrect. Refer then to the
respective lockout User’s Guide for
troubleshooting help.
