TESTING AND COMMISSIONING

The testing and commissioning phases are the most important when creating
an automated system in order to ensure maximum safety. The testing proce-
dure can also be performed as a periodic check of the automation devices.
These phases must be performed by qualified and experienced personnel who
must take charge of establishing the tests necessary to verify the solutions adopt-
ed in respect of risks and verify the compliance of the system with applicable
standards, legislation and regulations, in particular all requirements of the standard
EN 12445 which establishes the test methods for checking automated systems
for doors and gates. The additional devices must undergo specific testing, both
in terms of their functions and in terms of their interaction with the control unit;
therefore, you need to refer to the instruction manuals for the individual devices.

4.1 - Testing

The sequence of steps to be performed when running the testing phase, as
described below, refers to a typical system (Fig. 2):
1 Check that all the instructions in the "Installation warnings" chapter have
been rigorously complied with.
2 Using the control devices (transmitter, push button, key switch, etc.), test the
Opening, Closing and Stopping of the gate, ensuring that the movement of
the gate leaves corresponds to specifications. Test several times to assess
the movement of the gate and check for any defects in assembly or adjust-
ment and for any particular points of friction.
3 Check, one by one, that all the safety devices featured in the system (photo-
cells, sensitive edges, etc.) work properly.
4 If the dangerous situations caused by the movement of the gate leaves have
been safeguarded against by limiting the impact force, the impact force must
be measured according to the EN 12445 standard.
5 Check that the stopping distance of the gate is 2-3 cm, otherwise
adjust the mechanical brake as follows (fig. 8):
a. Give the nut on the motor shaft a half turn in a clockwise direction;
b. If the half turn isn't enough, turn the nut a little bit more;
c. Be careful not to over tighten the nut because it could completely block
the electric motor.
Before adjusting the mechanical brake, the power supply must be
turned off placing the main switch on the control unit in the "OFF"
position.
