gate completes a full opening. The test is available only if the safety strip device is equipped
with a dedicated power supply input.
In fact, the safety strip equipment power supply input can be connected to the A+TEST and
A- outputs (DIP10 ON). Automatically, every time the gate completes a full opening, just before
closing, the control board switches OFF the A+TEST and A- power supply output for a very
short time. While the safety strip power supply is switched OFF, if everything is working fine the
safety strip contact (EDGE - COM) must open. In case the test fails, no other gate manoeuvre
will be allowed and the alarm state will be signalled by both the Blinker and the Buzzer, if
installed, which will remain on for 5 minutes
NOT ALL THE SAFETY STRIPS CAN BE TESTED, THUS THE SWITCH DIP10 MUST BE
LEFT OFF.
STOP BUTTON
If the Automatic command is enabled (DIP 6 OFF), a Normally Closed contact could be
connected in series to the COM wire of the opened and the closed limit switches.
This contact works like a STOP button to interrupt any gate manouver.
FUNCTIONING IN DEAD MAN MODE WHEN THE SAFETY DEVICES ARE FAILING
If the safety edge fails or remains engaged for more than 5 seconds, or if photocell fails or
remain engaded for more than 60 seconds, the K BUTTON and PEDESTRIAN commands will
work only in dead man mode.
The signal that this mode has been activated is given by the blinking of the programming led.
With the blinking of the programming led, the opening and closing operation are allowed only
with the command button pressed and held. The radio commands and that of automatic closing,
will be excluded, since their use in this mode, is not allowed by the norms.
Once the failing safety device is repaired, in automatic after 1 second, all standard commands
that were selected, such as step by step, automatic mode, radio commands and automatic
closing start functioning again.
Note 1: during this functioning in dead man mode, in case of damage to the safety strips (or
photocells) the photocells (or safety strips) still work by interrupting the operation in
progress.
The dead-man operation is only an emergency operation which must be activated for
a very short period and with the complete installation at sight so to have a secure and
safe control of the system. As soon as possible however, the failing safety devices must
be repaired and activated.
FLASHING LIGHT
Connect the flashing light to J7 flashing light outputs, use flashing lights ACG7059 and bulbs
of 40W maximum.
NB: This electronic K board can only supply power to FLASHING LIGHTS with inbuilt flashing
circuit.
PRE-FLASHING function
The DIP 5 in the ON position enables the pre-flashing, the FLASHING LIGHT and BUZZER
starts working 3 seconds before every movement of the gate.
The DIP 5 in the OFF position disables any pre-flashing, the FLASHING LIGHT, the BUZZER
and the motor will start at the same time.
BUZZER (COM.+ BUZZER-)
The current supplied to the Buzzer will be 200 mA at 24Vdc.
During the normal operation of the gate, opening and closing, the buzzer will buzz intermittently.
Only during the alarm situations (safety strip) the buzzing will almost be constant.
GATE OPEN INDICATOR (A negativo - LSC)
It is turned ON when the gate is open or partially open, it is turned OFF only when the gate is
completely closed.
N.B.: connect in series to the indicator a resistance of 2K2. WE RECOMMEND NOT TO
OVERLOAD THE INDICATORS OUTPUT OTHERWISE THE GATE FUNCTIONING COULD
BE COMPROMISED OR THE CONTROL BOARD COULD BE DAMAGED.

- All inputs shall be used as clean contacts without earthing, because the power supply is
generated in the card and is structured in such a way to guarantee the respect of double and
reinforced insulation to the elements under voltage
- All inputs are managed by a programmed circuit that carries out a self-control every time the
gate is operated.

ROUBLESHOOTING
After having carried out all connections, by carefully following the layout and having positioned the gate in intermediate position, check the correct ignition of LEDS DL3, DL4, DL7, DL8.
In case of no ignition of the LEDS, always with gate in intermediate position, check the following and replace any faulty components.
DL3
switched off Faulty opening limit switch
DL4 switched off Faulty closing limit switch
DL7 switched off Faulty photocells
DL8 switched off Faulty safety edge (In case the edge is not connected, carry out jumper between COM and EDGE)
During functioning with personnel present, with DIP 1 at ON, check that during opening the green DL6 LED switches on and that during closing the red DL5 LED switches on.
If not, invert clamps V and W on the motor terminal board.
After having carried out the various connections and having supplied voltage, all the
LEDS are switched off.
The motor opens and closes, but it has no strength and moves slowly.
The gate opens but does not close after the time set.
The gate does not open or close by activating the various K and RADIO buttons.
By activating the K button the gate does not move.
The slowing phase is not performed.
Check the integrity of fuses F1 and F2. In case of interrupted fuse use only of adequate
value F2 = 5A F1 = 100mA.
Check trimmers TORQUE and LOW-SPEED adjustment.
Ensure to have set DIP 3 at ON.
Button K BUTTON always inserted in automatic functioning mode (DIP 6 OFF).
Replace button or switch of the selector switch.
Failed edge self-test => check the connections between electronic board and edge feeder.
Attention: if not using a feeder for edges, DIP 10 must be at OFF position.
Faulty safety edge contact. Faulty photocells contact with DIP 4 OFF.
Fix or replace the relative contact.
Impulse K always inserted. Check and replace any buttons or micro-switches of the selector
switch.
Ensure that DIP 8 is at position OFF (slowing enabled).
Learn the times through procedure from DIP 2.
Check trimmer LOW-SPEED adjustment.
