1 - 2

POWER input 230Vac, 50Hz, single-phase;

1 - 2 - 3

POWER input 400Vac, 50Hz, three-phase;

N.B.

Select working voltage with jumper SW1 before powering the board.

4 - 5 - 6

MOTOR output single-phase 230Vac or three-phase 400Vac, max. 700W, common=4,

opening phase=5, closing phase=6, for single-phase motors connect the capacitor be-

tween terminals 5 and 6;

7 - 8

FLASHING LIGHT output 230Vac, 20W max. The signal is already modulated for direct

use. Flashing frequency increases slightly during closing;

9 - 10

STOP button input (normally closed contact); this stops the automatic system. At the next

command, the opposite operation to the previous one is performed (common=9);

9 - 11

PEDESTRIAN button input (normally open contact); partially opens the automatic sys-

tem (by about 1 m) to allow pedestrians to pass by (common=9);

12 - 13

OPEN/CLOSE button input (contact normally open); for operating information see dip

switch 2 and 8 functions;

12 - 14

OPEN button input (contact normally open); for operating information see dip switch 3

functions (common=12);

12 - 15

CLOSE button input (contact normally open); for operating information see dip switch 3

functions (common=12);

16 - 17

FIXED SAFETY EDGE input (normally closed contact); only works during the opening

phase by temporarily stopping the gate and then closing it again by approx. 20 cm. A

manual command is required to continue operation (common=16);

16 - 18

PHOTOCELL or SAFETY DEVICES input (normally closed contact); if these trigger dur-

ing the closing phase, the gate stops and then completely reopens. During the opening

phase it temporarily stops the gate until the detected obstacle has been removed (if

programmed, dip switch 9 to ON), (common=16);

N.B.

the photocell transmitter must always be connected (terminals 27 and 28) as it is

checked by the safety system; the control unit will not work if it is disconnected. To

disable the safety system move dip switch 6 to OFF.

19 - 20

CLOSE LIMIT SWITCH input (normally closed contact), (common=19);

19 - 21

OPEN LIMIT SWITCH input (normally closed contact), (common=19);

N.B.

The thermal protection (for MASTER20T only) must be wired in series to the common

of the limit switch (terminal 19).

22 - 23

ENCODER power input (common=22-BLEU) (+5V=23-BROWN); the operation of the

ENCODER is governed by dip switch 5;
