DA.AX Control unit with microcontroller
The microprocessor control unit “DA.AX” can be used with motors having a power not exceeding 500W.
Installation instructions.
a) The electrical installation and functioning logic must comply with current standards.
b) It is advisable to keep the power cables (motor, power supply) detached from the control cables
(push-buttons, photocells, radio). In order to avoid any possible interference it is recommended
to provide for and use two separate sheaths (see EN 60204-1 15.1.3).
c) Before powering the unit, check again all connections which have been carried out.
d) Check the correct presettings of the Dip-Switches.
e) When the unit is powered, the LED “POWER” must be lit; in the negative, check fuses and that
230Vac 50Hz power supply is present between terminals 1 and 2 (INPUT 230VAC - keep to
phase / neutral).
f) The N.C. inputs not used must be connected to the common “+V”.
g) Should the direction of rotation of the motor be reversed, invert the motor wires “OPEN” with
“CLOSE” and the limit switches wires “FCA” with “FCC”.
Input/Output functions
(1,2) INPUT 230VAC= Control unit 230Vac 50 Hz power supply
(respect phase/neutral wire position).
(3,4,5) COM/APRE/CHIUDE= Connection to the corresponding 230Vac 50 Hz motor terminals
(the earth wire (green/yellow) must be connected to the motor housing).
(6,7) OUT 24VAC= 24Vac auxiliary power supply output (100mA max.).
(12) +V= Common connection to all the control inputs.
(9) FTC= Photocell receiver input (n.c. contact).
(10) FCA= Input of limit switch APRE (n.c. contact).
(11) FCC= Input of limit switch CHIUDE (n.c. contact).
(8) P.P.= Input, “PASSO-PASSO” push button or “APRE” push-button according to the Dip-Switch
presetting
(15) CHIUDE= CLOSE button input (n.o. contact).
(13,14) ANT.= Input of radio board antenna
Dip-switch functions
N.B.: Every change of functions have to be done without electricity.
DSW1= This selects the type of functioning of the P.P. button and Remote control.
Off= ”APRE” - ”STOP” - ”CHIUDE” functioning
On= ”APRE” - ”CHIUDE” - ”APRE” functioning.
DSW2= This enables or disables the automatic re-closing - ”TCA TRIMMER”.
Off= Automatic re-closing enabled
On= Automatic re-closing disabled
DSW3= This enables or disables the apartment building function (after the first opening command, the
P.P. button and the Remote control are deactivated).
