3.2 FUNCTIONING PROGRAMMING

At this stage it is possible to program the device. The two DIP-SWITCHES SW1 and
SW2 are used to select the pause time (SW1) and the functioning mode (SW2).
IMPORTANT - Each time the device is programmed, turn OFF the power supply to
RESET the previous program setting.
SW2 DIP-SWITCHES
SA MODE (SEMIAUTOMATIC) - When this functioning mode is selected and a single
pushbutton or radio control is used, the first pulse commands opening; the second the
stop and the third closing without any warning. Moreover, if another pulse is received
during closing, the movement direction is inverted and a further pulse is required when
the gate is open to command closing.
A MODE (AUTOMATIC) - When this functioning mode is selected and a pulse is sent,
opening is commanded to the limit switch, the gate remains open for the selected pause
time and then closes automatically.
• If a pulse is sent during the opening phase, the control system ignores it and the gate
continues to open.
• If a pulse is send when the gate is open, this RESETs the pause time (the count
starts again from zero).
• Finally, if a pulse is sent during the closing phase, the movement direction is inverted
(i.e. the gate opens again).
S MODE (SPECIAL AUTOMATIC) - This type of functioning is practically identical to
automatic functioning, the only difference being that, if a pulse is sent during opening,
the movement is immediately inverted without completing the cycle. Furthermore, if a
pulse is sent during the pause phase, the gate closes immediately.
VS MODE (AUTOMATIC FAST) - This type of functioning is the same as the previous
one (S MODE), but there is a fixed pause time of 0.5 sec.
UP MODE (DEAD MAN) - This type of functioning requires the physical presence of an
operator who opens and closes the gate. To use this functioning mode it is necessary to
connect two pushbuttons with normally open contacts to terminals 1 - 2 (opening
pushbutton) and 2 - 3 (closing pushbutton). To open the system it is necessary to press
and hold down the opening pushbutton and to close it the closing pushbutton. To stop
the system, just release the pushbutton.
SW1 DIP-SWITCHES
WORKING TIME - The switches S5, S6, S7 and S8 on unit SW1 can be set for 16
different working times from 3.5 to 240 seconds. This time must be selected so that it is
4-7 seconds more than the time necessary to open or close the gate.
PAUSE TIME - The switches S2, S3 and S4 on unit SW1 can be programmed to select
8 different pause times, from a minimum of 2 seconds to a maximum of 120 seconds. It
should be remembered that in the functioning modes where photocell zeroing is not
enabled, the pause time set is not constant, since it depends on the photocell activation
during the pause phase.
After selecting the functioning mode and times, it is advisable to check the external
devices connected to the board, checking the state of the relative LED on the board.
The board has two groups of LEDs:
• the first group to control the state of the inputs (start, stop and photocell/safety device)
• the second to control the piloting of relays and outputs (motor 1 relay, motor 2 relay,
direction relay, pilot light and diagnostics output and electric lock relay).

4.1 SIGNALLING LED

The N.C. input LEDs are ON when the contact on the terminal board is closed. This
means that the LEDs for the N.C. inputs (L2 and L3) are ON under normal conditions,
and these go OFF when the input is activated.
The N.O. input LED comes ON when this input is activated. This means that the start
LED (L1) is OFF under normal conditions and only comes ON when the input is active.
The output LEDs (L4, L5, L6, L7 and L9) are OFF when the device is in stand-by and
come ON during functioning, indicating which output is piloted at that moment.

4.2 CHECKING THE FUNCTIONING OF EXTERNAL DEVICES

START INPUT - If there is a short-circuit on the opening pushbutton or on the remote
control receiver when the device is powered up, a complete cycle is commanded followed
by blocking of the gate. This function, applies to all the functioning types, and guarantees
gate closing even in the event of a fault.
STOP INPUT - When the STOP pushbutton is pressed, that commands a N.C. contact,
the gate movement is blocked whatever the functioning phase. When the STOP
pushbutton is pressed again, the gate starts to close with a warning of 3 seconds.
PILOT LIGHT - The A40M-2 Professional device has a single output for the pilot light,
piloted with a voltage of 24 VDC and maximum power of 5 W. This light must always be
ON during the opening and pause phases and must flash as a warning on closing.
The A40M-2 Professional has an automatic trouble-shooting program, called diagnostics,
that makes it possible to check the correct functioning of the device and the accessory
devices connected to it.
To enable the diagnostic program, turn OFF the power supply and program the
"Diagnostics" logic using the SW2 DIP-SWITCHES (S1 to ON, S2 to OFF, S3 and S4 to
OFF). Then turn ON the power supply again.
In this way the following controls are performed:

• Microprocessor test

• Internal tests in automatic cyclic sequence
• Input circuit tests (by the technician)
5.1 MICROPROCESSOR TEST
This test is not visible because it is carried out inside the microprocessor and lasts a few
milliseconds. If the test result is positive, the diagnostic LED (L9) flashes rapidly five
times; in the event of an error, the diagnostic LED (L9) remains ON or OFF and the test
is blocked.
