Terminals
1 - “Open/Close Function” This is a normally open terminal where by any device (i.e. push
button, keypad, receiver) which, by closing a contact, provides an opening and/or clos-
ing pulse for both gate leaves (if there is only one leaf, it will control the one leaf).
2 - “Single Leaf Open/Close Function” This is a normally open terminal where by any de-
vice (i.e. push button, keypad, receiver) which, by closing a contact, provides an open-
ing and/or closing pulse for only the gate leaf controlled by the master control
board .
3 - “Stop Command” This is a normally closed terminal where by any device (i.e. push
button) which, by opening a contact, halts gate movement. IMPORTANT: If a connec-
tion is not made from this terminal to one of the - (negative) terminals (i.e. 12, 13, 14,
15) gate motion will not commence.
4 - “Opening Safety Device” This is a normally closed terminal where by any device (i.e.
photocells, sensitive edge, magnetic loops) which, if there is an obstacle in the area they
protect during opening, reverses gate direction to closing.
If the opening safety devices are tripped when the gate is closed, they prevent the leaf
movement.
IMPORTANT: If a connection is not made from this terminal to one of the - (negative)
terminals (i.e. 12, 13, 14, 15) gate opening will not commence. (
