Plug-In Loop Detectors
See Accessories
Contact your local dealer for information
about plug-in loop detectors.
The wire MUST be
twisted together
minimum 6 twists
per foot
from the end
of the loop to the
control board.
NOTE:
Refer to the plug-in loop detector
manual for more specific information.
Plug-In “Safety” Loop Detector -
Allows gate to
stay open when vehicles are obstructing path.
Caution: Suggested for vehicles 14 feet or longer.
If the “
Inside
” and “
outside
” safety loops are
connected to the same loop detector:
• They should be series connected to the detector.
• Have the same dimensions.
• Have the same number of wire turns.
Example of a inside and outside 2 wire turn loop
connected in series. (See “Installing Insulated Loop
Wire” on next page for more information)
Plug-In “Exit” Loop Detector -
Allows gate to
automatically open for exiting vehicles.
Example of a 3 wire turn loop. (See “Installing
Insulated Loop Wire” on next page for more
information)
To AVOID damaging control board, disconnect all power to
operator before installing plug-in loop detectors.
Use a different frequency for every loop detector installed.
