The TRC trimmer must be adjusted so that when closing, the wing
moved by the 2nd motor always reaches the end only after the 1st
motor has terminated the closing manoeuvre.
The Closing Delay Time can be used as a safety margin of 50 cm in
closing.
Now select the "Semiautomatic" functioning mode by positioning
dip-switch no. 1 in ON and adjust the Working Time trimmer to
about halfway of the travel distance. Having made these adjust-
ments, run a complete opening cycle followed by a complete clos-
ing cycle and readjust the Working Time trimmer as needed so that
there is enough time for the whole manoeuvre leaving a margin of
about 2 to 3 seconds. If the trimmer is on maximum and there still is
not enough time, the TLM jumper on the printed circuit near the trim-
mer can be cut to provide more working time.
In some types of actuators, for example the oleodynamic type, force
is adjusted directly on the actuator; consult the relative instruction
manual regarding adjustment and leave force adjustment inside the
unit on maximum.
For all the types of actuators that do not have a force adjustment
device it is possible to exploit the adjustment system of the force
inside the unit: on the basis of the unit version used, follow the rela-
tive instructions.
The following refers only to the A6 version
There is a FORCE trimmer on the unit which is usually set for maxi-
mum force; with a screwdriver turn the trimmer counterclockwise to
reduce motor force until you reach the value established by the stan-
dards.
4.1) Functioning modes
Note: some of the parts described below refer only to the A700F
version.
In the manual functioning mode the OPEN input consents to the
opening manoeuvre, the CLOSE input consents to the closing
manoeuvre, the STEP-BY-STEP consents to an alternating closing
and opening manoeuvre; as soon as the command in input stops,
movement stops. If, during an opening manoeuvre, the limit switch-
es trigger or if PHOTOCELL 2 (on the PIU' card) fails to give consent,
movement will stop; during a closing manoeuvre, on the other hand,
movement will also stop if there is no consent from PHOTOCELL
and PHOTOCELL 1. Whether in the opening or closing phase move-
ment, the activation of the STOP command will cause an immediate
stopping of movement and a short reverse run.
When a movement is stopped you have to stop the command in
input before a new command has the chance to start a new move-
ment. When in one of the automatic functioning modes (semiauto-
matic, automatic or close always), a command pulse on the OPEN
input will cause an opening manoeuvre; if the command persists
once fully open, the gate will stay in this position for a "infinite" pause
time; only when the command stops can the gate close again.
5) Programming
The unit comprises a set of microswitches used to operate various
functions so as to render the system more suitable to user needs
and safer in the different ways of usage. All functions are activated
by placing the dip-switch in the "ON" position while they will not be
activated if the corresponding dip-switches are "OFF"; some func-
tions do not have an immediate effect and only have sense in certain
conditions like, for instance, the No. 12 function "Flashing also in
pause time" which is only active with automatic closing and if the
manoeuvre is not interrupted with a STOP command.
The following refers only to the A6F e A700F versions
There is an adequately powered autotransformer on the unit with
intermediate sockets on the primary winding and which can be
selected by means of a special FORCE commutator; turn the com-
mutator round to the most suitable position to reduce motor force
until you reach the value established by the standards.
Maximum force is provided whatever system is used to adjust the
force for the initial movement phase and for a duration of 1.5 sec-
onds; only after this time, defined "Inrush", is the force established.
If you have chosen the automatic functioning mode (dip-switch No.
2 ON), the end of the opening manoeuvre is followed by a "pause"
time at the end of which a closing manoeuvre follows automatically.
The time the gate stays open can be adjusted with the PAUSE TIME
trimmer for the length of time you want, without any limits. An auto-
matic closing manoeuvre and the relative pause time are activated
also in the semiautomatic functioning mode when, in closing, the
triggering of a safety device will cause the gate to reverse direction.
Only now, when all the adjustments have been made, do we advise
you to plug in the radio receiver if you have one, reminding you that
the commands it sends are sent to the STEP-BY-STEP input.
A pulse on the STEP-BY-STEP causes an alternating closing and
opening manoeuvre. A second pulse on the STEP-BY-STEP or on
the input that started movement, will cause a Stop.
Both in the opening and closing phases, the activation of the STOP
command will cause an immediate stopping of movement and a
short reverse run.
If, instead of a pulse on a command input a continuous signal is
maintained, a state of "priority" will be created where the other com-
mand inputs are disabled (useful if you want to connect a timer or a
Night-Day selector). If you have chosen the automatic functioning
mode, subsequent to an opening manoeuvre there will be a pause
followed by a closing manoeuvre. If, during the pause time, either the
PHOTOCELL or PHOTOCELL 1 triggers, the timer will be reset with
a new pause time; if, on the other hand, there is a STOP during the
pause time, the reclosing function is cancelled and there is a STOP
state. Triggering of PHOTOCELL or PHOTOCELL 1 has no effect dur-
ing an opening manoeuvre but PHOTOCELL 2 (on the PIU' card) will
cause reversal of movement; the triggering of PHOTOCELL or PHO-
TOCELL 1 during a closing manoeuvre will cause reversal of move-
ment followed by a pause time and then a reclosing manoeuvre.
!
ATTENTION: some of the programmable functions are linked to
safety aspects, very carefully evaluate the effects of a function and
see which function gives the greatest possible level of safety.
When servicing a system, before you modify a programmable func-
tion, ascertain the reason why, during installation, certain choices
were made and then verify if, with the new programming, safety will
be impaired.
