The photocells must be connected depending on which area
they must protect. (See Fig. A5)
Closing Safety D : These photocells protect the area covered
by the gate during the closing movement. They have no effect
during the opening movement.
Opening Safety B-C : These photocells protect the area covered
by the gate during the opening movement. They have no effect
during the closing movement.
Opening/Closing Safety A : These photocells protect the area
covered by the gate both during the opening and the closing
movements.
The E024U board allows the connection of several safety devices
(for example photocells). With photocells you can activate the
FAILSAFE function, which, before each movement of the ope-
rator, tests each fotocells. In case the test fails the movement
is inhibited. To activate this function set to ON the dip-switch N.
11 and 12 of DS1, and connect the negative of the transmitter
to the OUT pin (No.9)
