During normal operation, the control unit constantly monitors the automation processes and is designed to indicate any faults that arise, by means of a pre-set
sequence of flashes emitted by the courtesy light and red led "L1" on the control unit (the diagnostics flashes always refer to the last action performed by the
automation). For an explanation of the number of flashes and associated cause, refer to Table 6 below:
Flashes
2 flashes - pause - 2 flashes
3 flashes - pause - 3 flashes
4 flashes - pause - 4 flashes
5 flashes - pause - 5 flashes
6 flashes - pause - 6 flashes
7 flashes - pause - 7 flashes
CAUTION! – All operations in this section must be performed exclusively
by skilled and qualified personnel, in observance of the instructions in the
manual, and current local legislation and safety standards in the place of
installation.
CONNECTING THE AUTOMATION TO THE ELECTRICAL MAINS
CAUTION!– When making this connection, the electrical mains power line
must be equipped with short-circuit protection device (between the automation
and the mains).
The electrical mains line must also be equipped with a power disconnect
device (with overvoltage category III, i.e. minimum gap between contacts of 3
mm) or an equivalent system such as socket with removable plug.
This device, when necessary, guarantees fast and safe disconnection of the
power supply and therefore must be placed in a location visible from the
automation. If the power disconnect device is not in the vicinity of the automa-
tion and not visible from the latter, it must be fitted with a lockout facility to pre-
vent inadvertent or unauthorised connection.
Note – The disconnect devices are not supplied with the product.
AUTOMATION TESTING AND COMMISSIONING
These are the most important phases of automation set-up to ensure maximum
system safety. The testing procedure described can also be performed as a
periodic check of automation devices.
Testing and commissioning of the automation must be performed by skilled and
qualified personnel, who are responsible for the tests required to verify the solu-
tions adopted according to the risks present, and for ensuring observance of all
legal provisions, standards and regulations, and in particular all requirements of
the standard EN 12445, which establishes the test methods for checking
automations for garage doors.
AUTOMATION TESTING
1 Ensure that all specifications in STEP 1 regarding safety have been strictly
observed.

WHAT TO DO IF... (troubleshooting guide)
Problem
During the Closing manoeuvre, the door stops and
inverts the current movement.
During the Opening or Closing manoeuvre the door
blocks suddenly and the control unit activates a brief
inversion of the manoeuvre in progress
During the Opening or Closing manoeuvre the door
blocks suddenly and the control unit activates a
Stop followed by a brief inversion of movement.
The automation does not respond to commands.
After a series of manoeuvres sent consecutively, the
automation is blocked.
The automation does not respond to commands.

TABLE 6
Solution
This reaction is caused by the activation of a specific pair of
photocells in the system, on detection of an obstacle.
Therefore remove the obstacle on the trajectory of these
photocells.
The leafs are subject to increased friction due to a sudden
obstruction (gust of wind, vehicle, person etc.). If adjust-
ment to sensitivity is required, refer to the Chapter "Adjust-
ments and other optional Functions".
A safety device installed (other than photocells, such as
sensitive edges) has detected a sudden obstacle.
Therefore remove the obstacle.
There is a system configuration error. Delete the entire
memory of the control unit and repeat installation.
The maximum admissible number of consecutive manoeu-
vres has been exceeded, causing excessive overheating.
Wait for a few minutes to enable the temperature to return
below the maximum limit.
Error in internal electric circuits. Disconnect all power cir-
cuits, wait a few seconds and then re-connect. Retry a
command; if the automation does not respond this may
indicate a serious fault with the electrical board of the con-
trol unit or motor wiring. Check and make replacements as
necessary.
2 Using the transmitter, perform door opening and closing tests and ensure
that the movement corresponds to specifications.
Test several times to assess smooth operation of the door and check for any
defects in assembly or adjustment and any possible points of friction.
3 Check operation of all system safety devices one at a time (photocells, sen-
sitive edges, etc.), Photocells: Activate the device during a Closing manoeu-
vre and check that the control unit stops the manoeuvre and activates a total
inversion of the movement (the courtesy light emits 2 flashes, twice). Sensi-
tive edges: Activate the device during an Opening or Closing manoeuvre and
check that the control unit stops the manoeuvre and activates a short inver-
sion of the movement (the courtesy light emits 4 flashes, twice).
4 To check the photocells, and to ensure there is no interference with other
devices, pass a cylinder (diameter 5 cm, length 30 cm) through the optic axis
joining the pair of photocells (fig. 45): pass the cylinder first close to the TX
photocell, then close to the RX and lastly at the centre between the two.
Ensure that in all cases the device engages, changing from the active status
to alarm status and vice versa, and that the envisaged action is generated in
the control unit (for example movement inversion in the Closing manoeuvre).
5 Measure the force as specified in the standard EN 12445. If the motor force
control is used as an auxiliary function for reduction of impact force, test and
identify the setting that obtains the best results.
6 Activate a closing manoeuvre and check impact force of the door against the
the floor surface. If necessary, test by discharging pressure to obtain the best
results.
AUTOMATION COMMISSIONING
Commissioning can only be performed after positive results of all test
phases. Partial or "makeshift" commissioning is strictly prohibited.
1 Prepare the automation technical documentation, which must contain the
following documents: Overall layout drawing (see example in fig. 6, 7, 8),
electrical wiring diagram (see example in STEP 6), risk assessment and rela-
tive solutions adopted (see forms to be compiled on the website www.nice-
foryou.com), manufacturer's declaration of conformity for all devices used
