The automation system must be tested by qualified
and expert staff who must establish what tests to perform
according to the relative risk.
Testing is the most important part of the whole installation phase.
Each single component, e.g. motors, radio receiver, emergency
stop, photocells and other safety devices, can require a specific test
phase; please follow the procedures shown in the respective
instructions manuals.
To test the control unit, carry out the following procedure (the
sequence refers to the A400 control unit with pre-set functions).
• Make sure that the activation of the STEP-BY-STEP input
generates the following sequence of movements: Open, Stop,
Close, Stop.
• Make sure that the activation of the AUX input (type 1 partial
opening function) only manages the Open, Stop, Close, Stop
sequence of motor 2 while motor 1 remains in the closed position.
• Engage each of the photocells or the other safety devices
connected to the PHOTO, PHOTO1 and PHOTO2 inputs and
make sure that no manoeuvres are made when a command input
is activated
• Perform an opening manoeuvre and check that:
– the gate continues the opening manoeuvre when PHOTO is
engaged.
– the manoeuvre stops when PHOTO1 is disengaged and only
continues when PHOTO1 is disengaged.
– the manoeuvre stops when PHOTO2 (if installed) is engaged and
the closing manoeuvre starts.
• Make sure that the motor switches off when the door reaches the
mechanical stop.
• Perform a closing manoeuvre and check that:
– The manoeuvre stops when PHOTO is engaged and the opening
manoeuvre starts.
– the manoeuvre stops when PHOTO1 is disengaged and the
opening manoeuvre starts when PHOTO1 is disengaged.
– The gate continues the closing manoeuvre when PHOTO2 is
engaged.
• Make sure that the stopping devices connected to the STOP input
immediately stop all and any movement.
• Check that the level of the obstacle detection system is suitable for
the application.
– During both the opening and the closing manoeuvres, prevent the
leaf from moving by simulating an obstacle and check that the
manoeuvre inverts before the force indicated by law is exceeded.
• Other checks may be required depending on what devices are
connected to the inputs.
If an obstacle is detected for 2 consecutive manoeuvres in the same
direction, the control unit partially inverts both motors for just 1 second.
At the following command, the leafs begin the opening manoeuvre and the
first current sensitivity cut-in for each motor is considered as stopping during
the opening cycle. The same thing happens when the mains power supply is
switched on: the first command is always an opening manoeuvre and the first
obstacle is always considered as stopping during the opening cycle.

5) Testing
The A400 control unit is an electronic component and therefore
needs no particular maintenance. Periodically check, however, at
least twice a year, that the whole system is in perfect working order
as indicated in the “Testing” chapter.
7) Servicing the A400 control unit
7.1) Disposal
This product is made from various kinds of material, some of which
can be recycled.
Make sure you recycle or dispose of the product in compliance with
current laws and bye-laws.
Some electronic components may contain polluting
substances; do not dump them.

6) Optional accessories
RADIO card
The control unit features a connector for plugging in an SM radio card , which activates the “Step-by-Step” and “Aux2” inputs and allows the
control unit to be remote-controlled through a transmitter.
