Installation of Limit Switches and Positive Stops
Positive stops are physical structures the gate comes in
contact with at the end of the opening and closing cy-
cles. The closed and open positive stop points can be a
plate on the end of the gate that comes in contact with
an adjacent post or an industrial door stop. (Many gates
need an extension piece added to make contact with the
doorstop.

Limit Switches
Mounting the limit switches
Slide the limit rings on the top side
of the transmission shaft. Line up
the holes on the limit switches with
the holes on the top of the operator.
Manually release the arm.
CLOSED GATE LIMIT SWITCH
Move the gate into the full closed
position then move the bottom ring
so it is pushing the switch on the
bottom limit switch in. Tighten the
screw on the bottom ring to secure
it in place
(see next page for screw
close up).

Although the E-SC 1600 control board comes equipped with a cycle time learning function,
physical stopping mechanisms must still be used. This can be done with limit switches
(not
included)
, positive stops
(not included)
or both. These must be installed before learning.
If using positive stops you must be on operating parameter:
OPEN GATE LIMIT SWITCH
Move the gate into the full open position. Move the top ring until it is pushing the switch on the top
limit switch in. Tighten the screw on the top ring to secure it in place.
