2.4) INSTRUCTIONS FOR CONNECTIONS:
Disconnect all power (24V and 230V) before carrying out any work on the system
We recommend waiting until installation is complete, the system tested and correct operation verified before plugging in the
optional RADIO or CHARGE cards. The optional cards are not necessary for the working of the system and if they are used they
make troubleshooting more complex.
If the inputs of the NC (Normally Closed) contacts are not used they should be linked out; if there is more than one then they
should be placed in SERIES with one another; if the inputs of the NO (Normally Open) contacts are not used they should be left
free. The inputs must be of the voltage free mechanical type; DO NOT USE Open Collector type inputs ("PNP", "NPN" etc.).
A) Carry out the necessary connections, following the diagram in Fig. 1; remember that there are specific standards that must
be complied with both as regards the safety of the electrical systems and as regards automatic doors and gates.
B) Power the door/gate and position it halfway, turn power off. It is now free to be opened or closed.
Do not power the gearmotor unless the necessary "Mechanical travel stops" have been installed!
C) Power the unit, checking immediately that a voltage of 230 V a.c. reaches terminals 1-2 and a voltage of 24 V d.c. reaches
terminals 5-6. As soon as the unit is powered the indicator lights (LEDs) on the active inputs should turn on and shortly after the
"OK" LED should start flashing regularly. If none of this happens, turn power off immediately and check the connections more
carefully.
The "OK" LED in the centre of the card has the job of signalling the state of the internal logic: regular flashing at 1 second intervals
means that the internal microprocessor is active and waiting for commands. When the microprocessor recognises a variation in
the state of an input (whether it is a command or function Switch input) it generates a quick double flash even if the variation
does not have any immediate effect. Quick flashing at 5 second intervals means that the release lever is open, the power voltage
is insufficient or an incorrect programme has been selected (see Chapter 4.1).
D) Now check that the LEDs relative to the NC contacts are on (all safety devices active) and that the LEDs relative to the NO
inputs are off (no command present); if this is not the case, check connections and effectiveness of the various devices.
E) Check that all the unit's safety devices are in proper working order (emergency stop, photocells, pneumatic edges, etc.): each
time they trigger the relative STOP, PHOTO or PHOTO2 LEDs, should turn off.
Do not move the gearmotor unless the necessary "Mechanical travel stops" have been installed!
F) The last thing to do is to check if movement is in the right direction. In the factory all the gearmotors are set for clockwise
rotation of the shaft in opening and anticlockwise in closing. To check that this is so, just press the small "CLOSE" key and see
whether or not the gate/door moves in the closing direction.
Whether the direction of movement is right or not, it is advisable to stop the manoeuvre immediately by pressing the small
"CLOSE" key again.
Now, if movement was not in the direction it should be then proceed as follows:
1 - Turn power off
2 - Unplug the "MOTOR" connector and plug it back in after having turned it 180°
3 - Unplug the jumper on the connector, "J8", turn it 180'and plug it back into the symmetrically opposite position
Once you have done this it is advisable to try movement again to see if the direction is correct, repeating the procedure in
paragraph "F".
NOTE:
When movement is reversed then all three operations described above must be carried out., If you turn the "MOTOR" connector
but you do not move the "J8" jumper, an error will be generated in the shaft rotation reading system (the gearmotor is controlled
in the opening phase but the system reads a movement in the closing phase) and in this case any attempt to move is stopped
straight away. This situation can be seen by means of the two "Ok-Encoder" LEDs that blink briefly after which the motor stops
immediately.
