MALFUNCTIONS: POSSIBLE CAUSES AND SOLUTION
The automation does not start
a_ Check there is 230Vac power supply with the multimeter;
b_ Set the SW1 jumper on the correct available voltage;
c_ Check that the NC contacts of the card are actually normally closed (5 green LEDs on);
d_ Set the dip 3 (man present function) to OFF, dip 5 (encoder) to ON, dip 6 (phototest) to
OFF;
e_ Check that the fuses are intact with the multimeter.
The radio control has very little range
a_ Connect the radio aerial to the terminals of the receiver card and not to terminals 31-32
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.
The gate opens the wrong way
a_ Invert the motor connections on the terminal block (terminals 5 and 6);
Consequently, invert the connections of the limit switches (terminals 20 and 21).
