24 ENCODER signal (WHITE), ENCODER operation is governed by dip switch 5 (only for
motors with ENCODER);
25 - 26 GATE OPEN LED output; 24Vac, max. 3W; the LED lights up at the same frequency as
the fl ashing light throughout the opening and closing manoeuvres; it then stays on when
the OPEN LIMIT SWITCH (FCA) is reached and switches off when the CLOSED LIMIT
SWITCH (FCC) is reached;
27 - 28 24Vac power output (only for the photocell transmitter) max. no. 1 photocell transmitter;
29 - 30 24Vac auxiliary power output (power input to photocells or other devices);
31 - 32 AERIAL input (earth=31, signal=32) (only for RX 40.665MHz);
33 - 34 2nd RADIO CHANNEL output;
C radio board connector.
TRIMMER
T.L. Work Time adjustment: from approx. 5 to 240 seconds;
T.C.A. Automatic Closing Time adjustment: from approx. 5 to 120 seconds (see dip switch 1);
FR. obstacle detection sensitivity adjustment (only for motors with encoder).
N.B.: turn the TRIMMER clockwise to increase adjustments; turn it anticlockwise to de-
crease.
Dip switches
1 on: after opening, the gate automatically closes when the delay set on the T.C.A. trimmer ex-
pires;
off: a command is required to close the gate;
2 on: with automatic closing enabled, a sequence of open/close commands causes the gate to
OPEN-CLOSE-OPEN-CLOSE etc.;
off: in the same conditions, the same command sequence causes the gate to OPEN-STOP-
CLOSE-STOP-OPEN-STOP (step-by-step) (see also dip switch 9);
3 on: Man Present; the automation system will continue to open or close as long as the OPEN or
CLOSE buttons are held down. The gear motor will stop when the button is released;
off: normal (or pulse); when the OPEN, CLOSE or the PP button is pushed, the automatic sys-
tem performs a complete opening or closing manoeuvre;
N.B. In the Man Present mode, the PP input (n° 14) is disabled, as is the radio receiver.
4 not used;
5 on: encoder disabled (obligatory if the motor is not fi tted with an encoder);
off: encoder enabled (only for motors with encoder);
6 on: pre-fl ashing and "photocell test" function enabled;
off: pre-fl ashing and "photocell test" function disabled;
7 on: after the photocell contact triggers (input 16 - 18), the automation system closes after 5
seconds;
off: function disabled;
8 on: the gate works as set by dip switch 2
off: the gate ignores the close command during the opening cycle;
9 on: during opening, the photocell cuts in to stop the gate until the obstacle is removed. During
