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.
All inputs are normally open and momentary, except the stop (NC), and emergency close & 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 advise given here, call for assistance.
Numbers shown inside a box are on the J1 terminal strip on the circuit board.
Connections shown here are field connections. The radio receiver may be ordered factory installed.
