PROGRAMMING DIP SWITCHES
N°1 Automatic closing disable:
OFF: automatic closing disabled
ON: automatic closing time (adjust with the T.C.A. trimmer)
N°2 2 or 4 step operation:
OFF: in the same conditions, the same command sequence causes the gate to OPEN –
STOP – CLOSE– STOP – OPEN– STOP, etc. (step by step function)
ON: with automatic closing enabled, a sequence of open - close commands causes the
gate to OPEN-CLOSE-OPEN-CLOSE, etc.
N°3 No reverse:
OFF: the gate ignores the close command while it is opening.
ON:
the gate behaves according to the position of dip-switch n° 2
N°4 Clock function:
OFF: the open-close pushbotton works in the standard mode.
ON: a timer can be connected to the open-close pushbutton in order to keep the gate open
at certain times during the day, after which it reverts to automatic closing.
N°5 Pre-flashing disable:
OFF: the light starts flashing when the automation is powered.
ON: the light starts flashing a few seconds before the automation is powered and the
photocells are checked.
POWER ADJUSTMENT
Power is adjusted by means of a four-position selector ranging from 1 (minimum power) to 4 (maximum
power). This selector adjusts operator force directly from the control unit.
SELF-DIAGNOSIS LED'S
The green LED's indicate the presence of normally closed contacts and are therefore always there
are system faults. The red LED's indicate normally open contacts and therefore when they are used
(except for LED 1 which indicates that the system is powered).
DL1 Red = indicates the board is powered
DL2 Red = indicates the OPEN – CLOSE command is working
DL3 Red = indicates the PEDESTRIAN command is working
DL4 Green = indicates the STOP command is working
DL5 Green = indicates the external photocell input is working
DL6 Green = indicates the internal photocell input is working
MALFUNCTIONS: POSSIBLE CAUSES AND SOLUTION
1- The automation does not start
a- Check there is 230Vac power supply with the multimeter;
b- Check that the NC contacts of the card are actually normally closed (3 green LEDs on);
c- Set dip 4 (timer function) to ON, dip 5 (phototest) to OFF;
d- Check that the fuses are intact with the multimeter.
2- The radio control has very little range
a- Connect the radio aerial to the terminals of the receiver card and not to terminals 24-25 of the
control card (for frequency 433,92 MHz);
b- Check that the ground and the aerial signal connections have not been inverted;
c- Do not make joints to increase the length of the aerial wire;
d- Do not install the aerial in a low position or behind walls or pillars;
e- Check the state of the radio control batteries.
3- The gate opens the wrong way
Invert the motor connections on the terminal block (terminals 5 and 7 for motor 1; terminals 8 and
10 for motor 2);
