Controls and Accessory Installation

See wiring diagram for more information. See Wiring Specifications on p. 9 for wiring
distances and wire gauge information.
All inputs are normally open and momentary, except the stop (NC), and emergency close and
emergency open (constant pressure). The following instructions are based upon UL 325, dated March
of 1999 and include recommendations for significant increase in safety.
We strongly recommend that you follow the UL guidelines presented throughout the manual.
Installation device instructions – always follow the instructions provided by the manufacturer when
installing and adjusting any control device. If these instructions are contrary to the advice given here,
call for assistance.
WARNING
All controls that are to be used to operate the gate system must be installed where the user
cannot touch the gate while operating the controls. Also, always install the controls where the
user has full view of gate operation.
