3. Connect NON-CONTACT sensors to the control board as shown
below.
NOTE: Close photocell is connected to “CLO PHO” and “COM” terminals.
Open photocell is connected to “OPN PHO” and “COM” terminals.
AFTER SENSORS ARE CONNECTED:
1. Turn on power.
2
. Make sure the photo-beams are properly aligned per the
manufacturer’s specifications.
3. Te
st the CLOSE obstruction sensing system for proper operation,
by blocking the beam across the gate opening while the gate i
s
r
unning closed.
NOTE: The gate should stop and reverse a short distance and then
stop.
