ENCODER:
If the encoder is used, you may select its pre-
sence.
If the encoder is present and enabled, “decele-
rations” and “partial opening” are controlled by
the encoder (see relevant paragraphs).
The encoder operates as an anti-crushing device:
If the gate strikes an obstacle during opening or
closing, the encoder immediately reverses gate
leaf movement for 2 seconds. If the encoder ope-
rates again during the 2-seconds reversing time,
it stops movement (STOP) without commanding
any reversing. If no sensor is supplied, the para-
meter must be set on
00
. If there is the encoder,
adjust the sensitivity of the anti-crushing system,
by varying the parameter between
01
(maximum
sensitivity) and
99
(minimum sensitivity).
From
01
to
99

Pre-limit switch DECELERATION:
You can select gate deceleration before the
opening and closing limit-switches have been
tripped.
Time can be adjusted from
00
to
99
.
If an encoder is used, the adjustment is not deter-
mined by time but by motor revs, thus obtaining
greater deceleration precision.
00
= Deceleration disabled
from
01
to
99
= Deceleration enabled

rA
Post-limit switch DECELERATIONS:
You can select gate deceleration after the
opening and closing limit-switches have been
tripped.
Time can be adjusted from
00
to
20
sec. in 0.04-
second steps.
If an encoder (optional) is used, the adjustment
is not determined by time but by motor revs, thus
obtaining greater deceleration precision.
00
= Deceleration disabled
from
01
to
20
= Deceleration enabled

PARTIAL OPENING:
You can adjust the width of leaf partial ope-
ning.
Time can be adjusted from
01
to
20
sec. in 0.1-
second steps.
If an encoder (optional) is used, the adjustment
is not determined by time but by motor revs, thus
obtaining greater precision of partial opening.
E.g. for a gate with a sliding speed of 10 m /min,
value
10
corresponds to about 1.7 metres of
opening.
E.g. for a gate with a sliding speed of 12 m
/min, value
10
corresponds to about 2 metres
of opening.

WORK TIME:
We advise you to set a value of 5 to 10 seconds
over the time taken by the gate to travel from the
closing limit-switch to the opening limit-switch and
vice versa. This will protect the motor against any
overheating if a limit-switch fails.
Adjustable from
0
to
59
sec. sec. in one-second
steps.
Subsequently, viewing changes to minutes and
tens of seconds (separated by a point) and time
is adjusted in 10 second steps, up to a maximum
value of
4.1
minutes.
E.g. if the display shows
2.5
, work time is 2 min.
and 50 sec.
the set value does not exactly match the mo-
tor’s maximum operating time, because
the latter is modified according to the
performed deceleration spaces.

ASSISTANCE REQUEST (combined with next fun-
ction):
If activated, at the end of countdown (settable
with the next function i.e. “Cycle programming”)
it effects 2 sec. of pre-flashing (in addition to the
value already set with the PF function) at every
Open pulse (job request). Can be useful for setting
scheduled maintenance jobs.

CYCLE PROGRAMMING:
For setting countdown of system operation cycles.
Settable (in thousands) from

thousand
cycles.
The displayed value is updated as cycles pro-
ceed.
This function can be used to check use of the
board or to exploit the “Assistance request”.

The table below shows the status of the LEDs in relation to to the status of
the inputs.
Note the following:
Led lighted
= closed contact
Led off = open contact

7. AUTOMATED SYSTEM TEST
When you have finished programming, check if the system is operating
correctly.
Most important of all, check if the force is adequately adjusted and if the
safety devices are operating correctly.
Note 1 : to reset the programming default settings, check if the edge
input is opened (SAFE LED OFF), and simultaneously press keys +,
- and F , holding them down for 5 seconds.
Note 2: modification of programming parameters comes into effect
immediately, whereas definitive memory storage occurs only
when you exit programming and return to gate status viewing. If
the equipment is powered down before return to status viewing,
all modifications will be lost.
