OPENING PHOTOCELLS LOGIC:
Select the tripping mode of the opening
photocells.
They operate for the opening movement
only: they stop the movement and restart it
when they are released, or they reverse it
immediately.
= Reverse immediately to closing
= Restart movement on release
ENCODER:
If the encoder is used, you may select its presence.
If the encoder is present and enabled,
"decelerations" 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
operates again during the 2-seconds reversing
time, it stops movement (STOP) without
commanding any reversing. If no sensor is
supplied, the parameter must be set on
. If
there is the encoder, adjust the sensitivity of the
anti-crushing system, by varying the parameter
between
(maximum sensitivity) and
(minimum sensitivity).

Note 1
: to reset the programming default settings, check if the
edge input is closed (SAFE LED ON), 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.
Pre-limit switch DECELERATION:
You can select gate deceleration before the
opening and closing limit-switches have been
tripped.
Time can be adjusted from
to
in
0.1-second steps.
If an encoder is used, the adjustment is not
determined by time but by motor revs, thus
obtaining greater deceleration precision.
= Deceleration disabled
from
to
= Deceleration enabled
Post-limit switch DECELERATION:
You can select gate deceleration after the
opening and closing limit-switches have been
tripped.
Time can be adjusted from
to
in
0.1-second steps.
If an encoder is used, the adjustment is not
determined by time but by motor revs, thus
obtaining greater deceleration precision.
= Deceleration disabled
from
to
= Deceleration enabled
ASSISTANCE REQUEST (combined with next
function):
If activated, at the end of countdown
(settable with the next function i.e. "Cycle
programming") it effects 2 sec. (in addition to
the value already set with the PF function) of
pre-flashing at every Open pulse (job
request). Can be useful for setting scheduled
maintenance jobs.
= Active
= Disabled
WORK TIME (tome-out):
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.
Adjustable from
to
sec. in one-
second steps.
Subsequently, display 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
minutes.
Attention: the set value does not exactly
match the motor's maximum operating time,
because the latter is modified according to
the performed deceleration spaces.
PARTIAL OPENING:
You can adjust the width of partial leaf
opening.
Time can be adjusted from
to
in
1 second steps.
If an encoder is used, the adjustment is not
determined by time but by motor revs, thus
obtaining greater partial-opening precision.
For example, with pinion Z20, partial opening
can vary from about 60 cm to 4 m.
CYCLE PROGRAMMING:
For setting countdown of system operation
cycles. Settable (in thousands) from
to
thousand cycles.
The displayed value is updated as cycles
proceed.
This function can be used to check use of the
board or to exploit the "Assistance request".
GATE STATUS:
Exit from programming, data saving, and
return to viewing gate status (see par.
5.5.1.).
