Introduction; Description - Nice MINDY A6-A6F Mode D'emploi

English

1) INTRODUCTION:

The electronic unit is designed to control the movement of automatic gates and doors; it can be connected to electromechanical
actuators equipped with asynchronous single-phase motors running on 230 V a.c., for example the PLUTO PL 4000 or METRO
ME 3000 models, made by Nice.
This instruction manual refers to several versions of the same unit; the difference of the various versions lies in a different
completion of the programmable functions and of the inputs available besides a different method used to control actuator force:
A6 : Base version, adjustment of the electronic force with phase step control
A6F : Base version, adjustment of the electromechanical force with commutable autotransformer
A700F : Complete version, adjustment of the electromechanical force with commutable autotransformer
"Manual", "semiautomatic" or "automatic" operations are possible with this unit; during movement the consents of the safety
devices (STOP, PHOTOCELL, PHOTOCELL 1 inputs) are controlled; in the A700F version movement limits are verified by means
of the limit switch, while in the A6 version movement is timed.
It has sophisticated, logical type functions going from "Movement memory" to "Close immediately after Photocell", passing by
"Close always" and certain operating functions such as "Gradual start", "Gradual stop".
In the A700F version, by plugging in the "PIU" model expansions cards, you can expand the functions even more by means of
other inputs and outputs.
All the units are designed for connecting a wide range of Nice made radio receivers.
The most advanced techniques have been adopted in the project to guarantee maximum immunity to interference, greater
flexibility of use and the widest choice of programmable functions.

1.1) DESCRIPTION:

In view of this product's peculiarities and the use of techniques that cannot be compared to other similar products, before you start
installing the unit and wiring it, here is a brief description of the most important elements on the card.

The task of the OK LED (16) is to signal the correct functioning of the internal logic; it must flash at 1 second intervals and indicates
that the internal microprocessor is working and waiting for commands. Whenever there is a variation in the state of the inputs (10-
11) or of the function dip-switches (7), a double, quick flashing is generated even if the effects of the variation are not immediate.
When the unit is powered, the luminous indicators (9) on the inputs turn on if that particular input is active and if there is a control
voltage of 24 Vac. As a rule, the LEDs on the safety device inputs STOP, PHOTOCELL and PHOTOCELL 1 and those on the limit
switches are always on while those on the STEP-BY-STEP, OPEN and CLOSE are normally off.
