•If only one leaf is present, the entire sequence must
nevertheless be effected. When the leaf has finished
opening, supply 4 pulses with key
+
until the leaf begins
to close, and then resume normal procedure.
5.3 OPERATION WITH GATECODER
By pressing key
+
the following functions are pulse-controlled:
1
st
PULSE -Deceleration on opening of leaf 1 (it stops
automatically on reaching the stop limit)
2
nd
PULSE -Leaf 2 opening movement begins
3
rd
PULSE -Deceleration on opening of leaf 2 (it stops
automatically on reaching the stop limit)
4
th
PULSE -Leaf 2 closing movement begins
5
th
PULSE -Deceleration on closing of leaf 2 (it stops
automatically on reaching the stop limit)
6
th
PULSE -Leaf 1 closing movement begins
7
th
PULSE -Deceleration on closing of leaf 1 (it stops
automatically on reaching the stop limit)
8
th
PULSE -Exit learning cycle
The display stops flashing and the gate is ready for normal
operation.
Notes:
•The deceleration pulse should be supplied a little earlier
with respect to the stop limit to prevent the leaf reaching
it at full speed (it would be taken for an obstacle).
•If only one leaf is present, the entire sequence must
nevertheless be effected. When the leaf has finished
opening, supply 5 pulses with key
+
until the leaf begins
to close, and then resume normal procedure.
5.4 OPERATION WITH LIMIT-SWITCH AND
GATECODER
When the learning cycle is stated, leaf 1 opens and deceleration
begins when FCA1 operates. The stop limit is recognised
automatically. By pressing key
+
the following functions are
controlled by means of the successive pulses:
1
st
PULSE -Leaf 2 starts its opening movement. The start-of-
deceleration point is commanded by the
intervention of FAC2 and the stop limit is
automatically recognised.
2
nd
PULSE -Leaf 2 starts its closing movement. The start-of-
deceleration point is commanded by the
intervention of FCC2 and the stop limit is
automatically recognised.
3
rd
PULSE -Leaf 1 starts its closing movement. The start-of-
deceleration point is commanded by the
intervention of FCC1 and the stop limit is
automatically recognised.
4
th
PULSE -Exit learning cycle
Notes:
•If some limit-switches are not installed, start the
corresponding deceleration by pressing key
+
(which
replaces the limit-switch).
•If only one leaf is present, the entire sequence must
nevertheless be effected. When the leaf has finished
opening, supply 5 pulses with key
+
until the leaf begins
to close, and then resume normal procedure.
6. CONNECTIONS
Inputs 18,19,20,21 of 462 DF are designed for the connection of
opening and closing limit-switches which, according to type of
programming - can command either leaf stop or start of
deceleration. The non-used limit-switches must be jumper
connected (if none are used, this is unnecessary).
Gatecoders can be installed to detect the leaf's angular position
and obtain the electronic anti-crushing function and
deceleration.
The limit-switches and Gatecoders can also be used combined
(for details refer to paragraphs 4.4 and 4.5). To wire, consult fig. 2,3,
and4.
FCA1 - Leaf 1 opening limit-switch
FCC1 - Leaf 1 closing limit-switch
FCA2 - Leaf 2 opening limit-switch
FCC2 - Leaf 2 closing limit-switch
N.B.:
Maximum configurations are shown on the drawings. All
intermediate configurations are allowed, using only some
elements (only 1 Gatecoder, only 1 limit-switch, 2
Gatecoders and 2 limit-switches etc.).
