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qualied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specic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specications.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 (g. 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.
