Test - Nice MINDY A6-A6F Mode D'emploi

The following is applicable only to the A700F version
A particular description is given about the "Phototest" output which is
nothing else but the best possible solution in terms of reliability as
regards safety devices. Each time a manoeuvre is activated the
relevant safety devices are checked and only if everything is in order
will the manoeuvre start
Should the test be unsuccessful (the photocell is blinded by the sun,
cables have short circuited, etc.) the failure is found and the
manoeuvre is not carried out.
All this is possible only by using a certain configuration in the safety
devices' connections (Fig. 5).
As you can see from the wiring diagram, while the receivers of the
photoelectric cells PHOTOCELL, PHOTOCELL 1 (and PHOTOCELL 2
if it exists - on the PIU' card) are normally supplied by the accessories'
24 V a.c., the transmitters take their power from the phototest output.
When movement is requested, first of all it is verified that all the
receivers involved in the movement give their consent then the phototest
output is turned off after which it is checked that all the receivers signal
the fact by removing their consent; lastly, the phototest output is
reactivated and consent of all the receivers is verified once again.
As you can see, synchronism has been activated on the two
transmitters by cutting the jumpers: this is the only way to guarantee
that the two pairs of photoelectric cells do not interfere with one another. Check the instructions in the photocell manual regarding
synchronised functioning.
If the "PHOTOCELL" input is not going to be used its terminal must be jumpered via the 24 VAC relay connected on the
PHOTOCELL TEST output.

As a rule gearmotors are used on 2-wing gates that do not need limit switches; it is normal practice to install mechanical stops
that stop movement in the point wanted. There is also a "Working Time" trimmer on the control unit that is usually set for a time
slightly longer than the time actually needed for the complete manoeuvre. When the gate reaches the mechanical stop the motor
stops and remains under stress for the rest of the time; the motors are always designed to withstand this kind of stress without
any trouble, especially if the force is set at values lower than 100%.
•
In some installations, like for instance in the case of two sliding gates or if you wish to exploit the positioning function, limit
switches might be needed. In the majority of cases, if limit switches are used they are the normally closed (NC) type so that if
a failure does occur it will cause the motor to stop without the gate getting stuck. In other cases, like for example when magnetic
type contacts are used, it is possible that normally open type limit switches have to be used (NO). To enable the control unit to
use NO type limit switches you have to cut the FC jumper on the card (Fig. 2). This jumper can also be cut even if limit switches
are not used which will avoid having to install the relative jumpers.
•
Depending on the type of gearmotor and on the function you wish to achieve, the limit switches can be used as indicators of the
end of travel point (limit switch function) or to signal the starting point of the positioning function. If they are used for positioning,
they are normally installed at an angle of 10-20° from the stopping point and they indicate the point at which an even weaker
force will be applied to the motors, adjustable by means of the POSITIONING FORCE trimmer, so the gate will stop
mechanically as gently as possible.

3) TEST:

Once the motor and various accessories have been connected you can now check all the connections and test the plant.
ATTENTION: the next operations entail working on live circuits, most of the circuits are in extra low safety voltage so they
are not dangerous but some are under mains voltage which means they are HIGHLY DANGEROUS! Pay maximum attention to
what you are doing and NEVER WORK ALONE!
We recommend working in the manual mode with all the functions deactivated (dip-switches OFF); in all cases, when you are
working in the manual mode and you release the control key the motor will stop immediately. Also check that all the adjustment
trimmers are on minimum (turned in the counterclockwise direction); only the FORCE trimmer (on A6) or the FORCE commutator
(on A6F and A700F) can be positioned on maximum; the Positioning Force trimmer (on A700F) must be positioned halfway.
A) Unlock the gate and take the wings to the halfway point and then lock them; now the gate is free to move in either the opening
or closing direction.
Do not power the unit unless all the standards relative to the automatic gate category are observed!
B) Power the unit and check that voltage between terminals 1-2 and 1-3 is 230 V a.c. and 24 V a.c. between terminals 21-22.
