Product Description And Applications - Nice Mindy A6 Instrucciones Y Advertencias Para El Instalador

2) Product description and applications

The electronic unit is designed to control the movement of automatic gates; it can be connected to electromechanical actuators equipped
with asynchronous single-phase motors.
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 logical type functions going from "Movement memory" to "Close immediately after Photocell", pass-
ing 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.
Before you start installing the unit and wiring it, here is a brief description of the most important elements on the card.
1
1. Power transformer (only A6)
2. Plugs for external autotransformer (only A6F or A700F)
3. 500 mA rapid fuse on 24 Vac power
4. Plug for RADIO card
5. Times adjustment trimmers
6. Aerial terminal board and 2nd RADIO channel output
7. Dip-switch to select functions
8. Plug for the PIU' card (only A700F)
9. Indicator LEDs to signal state of the inputs
10. Terminal board for inputs of safety devices and controls
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 func-
tion 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.
