Learning Of The Mechanical Stop Positions; Checking The Boom's Movement; Connecting Other Devices; Testing And Commissioning - Nice M3BAR Instructions And Warnings For Installation And Use

Start the procedure by activating parameter Set 1 (refer to the
chapter "PROGRAMMING").
The self-learning phase of the connected devices can be re-
peated at any time also after the installation, for example when-
ever a device must be added.
5.4 LEARNING OF THE MECHANICAL STOP
POSITIONS
Once the connected devices have been learned, the mechani-
cal stop positions must be learned (maximum opening and max-
imum closing).
To do this:
unlock the gearmotor with the relevant key provided (refer
1.
to the "Manually unlocking and locking the gearmotor"
paragraph)
manually move the boom to about half-way (45°) and
2.
leave it stationary
lock the gearmotor
3.
4. start the level search procedure by activating parameter
Set 2 (refer to the chapter "PROGRAMMING")
5. while the manoeuvres are being executed, make sure that
the boom's balancing lever strikes the mechanical stops
of the limit switch. If this does not occur, stop the pro-
cedure by pressing encoder (A), adjust the mechanical
stops of the limit switch and repeat the procedure from
the beginning
a
Do not interrupt the execution of the manoeuvres: if
this occurs, the entire procedure must be repeated
from the beginning.

5.5 CHECKING THE BOOM'S MOVEMENT

Once the devices have been learned, it is advisable to carry out
a few manoeuvres in order to verify that the gate moves prop-
erly.

there are no points of excessive friction and that there are
no defects in the assembly or adjustments.

5.6 CONNECTING OTHER DEVICES

If the user needs to power external devices, such as a radio
receiver or the light of the key selector switch, power can be
tapped as shown in the figure.
The power supply voltage is 24Vc -30% ÷ +10% with a maxi-
mum available current of 500mA.

TESTING AND COMMISSIONING

These are the most important phases of the automation's con-
6 TESTING AND COMMISSIONING
struction, as they ensure maximum safety of the system. The
test can also be used to periodically verify the devices making
up the automation.
m
Testing and commissioning of the automation must
be performed by skilled and qualified personnel,
who are responsible for the tests required to ver-
ify the solutions adopted according to the risks
present, and for ensuring that all legal provisions,
standards and regulations are met, in particular all
the requirements of the EN 12445 standard, which
defines the test methods for checking gate automa-
tions.
The additional devices must undergo specific testing, both in
terms of their functions and their proper interaction with the con-
trol unit. Refer to the instruction manuals of the individual devic-
es.

6.1 TESTING

To run the test:
verify that all the instructions stated in the "GENERAL
1.
SAFETY WARNINGS AND PRECAUTIONS" chapter
have been strictly observed
check that the boom is correctly balanced (see paragraph
2.
"Boom balancing")
check that the manual unlocking device works properly
3.
(see paragraph "Manually unlocking and locking the
gearmotor")
4. using the control devices (transmitter, control push-but-
ton, key selector, etc.), test the boom opening, closing
and stopping phases, ensuring that the movement match-
es the specifications. Several tests should be conducted
to assess the boom's movement and to check for any as-
sembly or adjustment defects or any particular points of
friction
