Opening leaf delay
Programming of microswitch SW1 enables delay of the opening start of
leaf 2 with respect to leaf 1, in order to avoid the leaves obstructing each
other during the initial stage of movement.
Closing photocells logic
By using microswitch SW2, you can select the type of behaviour of the au-
tomated system if the photocells protecting the gate closing movement
are engaged. You can obtain either immediate reversing of the leaves or
a stop followed by reversing when the photocells are disengaged.
Fail safe
Programming the microswitch SW3 makes it possible to activate or de-ac-
tivate the photocells control test. When Fail safe is active, the equipment
checks the photocells before every opening or closing movement.
Reversing stroke
By using the microswitch SW4, you can activate the "reversing stroke".
The "reversing stroke" pushes the leaves to close for a few moments before
opening the gate, thus facilitating release of the electric lock.
The equipment is endowed with two groups of microswitch-
es - DS1 (fig. 18a) and DS2 (fig.18b) - which make it possible
to program the gate operation parameters.

Leaf l and 2 force
By using microswitches SW1, SW2 and SW3, the force (and thus anti-
crushing safety) of the operator connected to leaf 1 can be programmed.
The same operation has to be repeated on the motor connected to
leaf 2, by using microswitches SW4, SW5 and SW6.
As concerns the hydraulic operators, select maximum
force (level 8) on the equipment and adjust thrust with
the operator by-pass valves.
Function logic
The automated system's function logic can be selected with micro-
switches SW7, SW8, SW9 and SW10. By selecting an automatic logic
(A, SP), the combination of microswitches enables selection of pause time
too (waiting time, in opening position, before automatic re-closing).
The available logics - their operation is described in tables 3/a-b-c-
d-e-f, are as follows: A - SP (Automatic), E - EP - B (Semi-automatic),
C (Dead-man).
Closing leaf delay
Programming of microswitches SW11 and SW12 enables delay of the
closing start of leaf 1 with respect to leaf 2, in order to avoid the leaves
overlapping during movement, and thus increase the safety of the
system.
