SAFETY EDGES
The two inputs, that are fitted to control the safety edges, are separated for the opening and closing phases. Also, it is possible to select the type of contact connected
to them, either NC mechanical or 8,2 kΩ resistive, by means of the two jumpers JA1 or JA2 (SELECT EDGE TYPE).
Thanks to a dedicated microcontroller circuit separately fitted on to the board, the actual integrity and correct functioning of the safety system is constantly controlled.
Any possible fault or loss of efficiency is signalled by the L33 and L34 LEDs keeping flashing.
Selecting functioning:
Gate travel is reversed on
JB opening and closing for a short
spell.

Gate travel is reversed in

opening and closing for twice
as much the spell.

Once the safety edge has been engaged and the
JB obstacle removed, the gate closes automatically
(if automatic close mode has been selected).

Once the safety edge has been engaged and the
obstacle removed, the gate stays stopped until a new
JB
pulse is given (even if automatic close mode has
been selected).
