INSTALLATION AND ELECTRICAL CONNECTION
OF TWO CONTROL UNITS FOR LEAVES MOVING
IN OPPOSITE DIRECTIONS
To create an automation consisting of two leaves moving in opposite directions,
it is necessary to use two control units connected as shown in Fig. 20.
The motors and limit switches must be connected to each control unit. The
warning light and the G.O.I. (Gate Open Indicator) can be connected to any
one of the two control units, or can be installed one on each control unit (Fig.
Apage6).
Theinputsmustbeplacedparalleltooneanother;the“Common”inputcanbe
connected to either one of the two control units.

which allows for synchronising the leaves should the two control units lose their
synchronisation.
Withthiscongurationitisimportanttorememberthat:
• the intervention of the sensitive edge only impacts the single leaf;
• the red STOP key only impacts the single leaf;
• the intervention of the thermal protection device only impacts the single leaf.

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.
8.1 - Testing
The sequence of steps to be performed when running the testing phase, as
describedbelow,referstoatypicalsystem:
1Check that all the instructions in the “Installation warnings” chapter have
been rigorously complied with.
2Releasethemotor.Checkthatthegatecanbemanuallymanoeuvredwitha
forcenogreaterthan225N.
3 Lock the motor.
4 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.
5 Check, one by one, that all the safety devices featured in the system (photo-
cells, sensitive edges, etc.) work properly.
6 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.
8.2 - Commissioning
Commissioning can only be performed after obtaining positive results in all the
testphasesrunonthecontrolunitandtheotherdevices(paragraph8.1).It is
not permissible to execute partial commissioning or to enable use of
the system in “makeshift” conditions.
1 Prepare and store the technical documentation for the automated system
foratleast10years.Thismustincludeatleast:anassemblydrawingofthe
automated system, a wiring diagram, an analysis of hazards and solutions
adopted, a manufacturer’s declaration of conformity of all the devices installed
(forthecontrolunit,usetheannexedCEdeclarationofconformity);acopyof
the automation system instruction manual and maintenance schedule.
2Postalabelonthegateprovidingatleastthefollowingdata:typeofauto-
mated system, name and address of manufacturer (person responsible for
the“commissioning”),serialnumber,yearofmanufactureand“CE”marking.
3 Post a permanent label or sign near the gate detailing the operations for
releasing the system and its manual operation
4 Post a permanent label or sign on the gate containing this picture (min. height
60mm).
5 Prepare the declaration of conformity for the automation system and hand it
to the owner.
6Preparethe“Instructionsandwarningsfortheuseoftheautomationsystem”
and hand it to the owner.
7 Prepare the maintenance schedule for the automation system and hand it to
the owner; it must include all the instructions regarding maintenance of the
individual devices.
