MEMORISING THE PEDESTRIAN OPENING FOR A MOTOR
1- Move dip 4B to ON; the light will start flashing.
2- Press the PEDESTRIAN button; the gate connected to motor M1 will start closing.
3- Wait for the gate to open again
4- Stop the gate at the required point by pressing the PEDESTRIAN button.
5- Press the PEDESTRIAN button again or wait for the pause time to elapse for the gate to close.
6- Move dip 4B to the OFF position and check the light stops flashing.
Memorising has now terminated.
MEMORY RESET
If any or all of the previously modified settings need to be changed, proceed as follows:
1- power the control card,
2- touch the two pins of the JP1 jump with the tip of a screwdriver for at least 1 second,
3- the previously memorised settings have now been deleted.
The position of dip 4B is irrelevant during this operation.
EQUIPMENT DATA
The control panels for the automatic opening of models MEC 1000 and MEC 2000, comply with the following
characteristics:
- power voltage: 230Vac
- voltage of the power circuits that supply the motors: 19Vdc
- auxiliary circuit voltage: 19Vdc
- electronic circuit voltage: 5Vdc
- the equipment is guaranteed to work outdoors under normal working conditions which are specified
below:
- ambient temperatures no higher than 50°C (average value referring to a time of 24 hours no higher than
45°C)
- ambient temperatures no lower than -20°C
- nominal current of the motor's power circuit: 10A for each motor
- nominal current of the auxiliary circuits: 3,15A.
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_ Check that the fuses are intact with the multimeter;
MEC1000
Set dip 1 B to OFF, dip 8 A to OFF, dips 9 and 10 A to ON;
MEC2000
Set dip 1 B to ON, dips 9 and 10 A to ON.
2_ The radio control has very little range
a_ Connect the radio aerial to the terminals of the receiver card and not to terminals 27-28 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 motors function in reverse
a_ Invert the motor connections on the terminal block (terminals 7 and 8 for motor 1; terminals 9 and
10 for motor 2);
