2.7 - Automatic search system for the limit switches
On the successful completion of the various controls, start the automatic search
system phase for the limit switches. This work is necessary as the MC424L
control unit must “measure” how long the opening and closing manoeuvres
take This procedure is completely automatic and detects the mechanical open-
ing and closing stops by measuring the load on the motors.
are enabled (STOP, PHOTO and PHOTO1). The procedure will be immediately
interrupted if a safety device triggers or a command arrives. The leafs MUST
be positioned at approximately mid-travel.
Procedure – At the same time, press buttons P2 (Stop/Set) and P3 (Close
▼) (g. 2) to start the search stage that includes:
- Check and save the motor selector switch.
- CheckandsavetheALTinput(NC/8.2KΩ).
- Bothmotorsopenbriey.
- Motor closes the lower leaf until it reaches the mechanical closing stop.
- The upper leaf motor closes until it reaches the mechanical closing stop.
- The motor of the upper leaf begins to open.
- After the programmed delay, opening of the lower leaf begins. If the delay is
insufcient,blockthesearchbypressingP2(Stop/Set)(g. 2), then modify
thetime(seechapter5).
- The control unit measures the movement required for the motors to reach the
opening mechanical stops.
- Complete closing manoeuvre. The motors can start at different times, the aim
is to prevent the leafs from shearing by maintaining a suitable delay.
- End of the procedure with memorisation of all measurements.
All these phases must take place one after the other without any interference
from the operator. If the procedure does not continue correctly, it must be
interrup ted with the P2 (Stop/Set) button. Repeat the procedure, modifying
some parameters if necessary, for example the current sensitivity cut-in thresh-
olds(seechapter5).Thisprocedurecanberepeatedwithoutneedingtodelete
the memory.
These are the most important phases of automation set-up for ensuring maxi-
mum system safety. The test can also be performed as a periodic check of
automation devices. Testing and commissioning of the automation must be
performedbyskilledandqualiedpersonnel,whoareresponsibleforthetests
required to verify the solutions 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 doors and gates.
Theadditionaloroptionaldevicesmustundergoaspecictestforfunctionality
and correct interaction with MC424L. Refer to the instruction manuals of the
individual devices.
TESTING AND COMMISSIONING
3
3.1 - Testing
The testing sequence refers to the control unit programmed with the preset
functions.Seeparagraph5.1:
• Make sure that the activation of the STEP-BY-STEP input generates the fol-
lowing sequence of movements: “Open, Stop, Close, Stop”.
• Make sure that the activation of the AUX input (Type 1 partial opening func-
tion) manages the “Open, Stop, Close, Stop” sequence of the motor of the
upper leaf only, while the motor of the lower leaf remains in the closed posi-
tion.
• Perform an opening manoeuvre and check that:
- the gate continues the opening manoeuvre when PHOTO is engaged
- the opening manoeuvre stops when PHOTO1 is engaged 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 an opening manoeuvre and check that:
- The manoeuvre stops when PHOTO is engaged and the opening manoeuvre
starts
- The manoeuvre stops when PHOTO1 is engaged and the opening manoeu-
vre starts again when PHOTO1 is disengaged
- the gate continues the closing manoeuvre when PHOTO 2 is engaged
• Check that the stop devices connected to the ALT input trigger the immedi-
ate stopping of any movement in progress and a slight reversal
• Check that the level of the obstacle detection system is suitable for the appli-
cation:
- During both the opening and the closing manoeuvres, prevent the leaf from
moving by placing an obstacle and check that the manoeuvre inverts before
exceeding the force set down by law
• Other checks may be required depending on which devices are connected to
the inputs.
Warning – If an obstacle is detected as moving in the same direction for
2 consecutive manoeuvres in the same direction, the control unit par-
tially inverts both motors for just 1 second. At the following command,
the leafs begin the opening manoeuvre and the rst current sensitiv-
ity cut-in for each motor is considered as a mechanical stop during
the opening cycle. The same happens when the mains power supply is
switched on: the rst command is always an opening manoeuvre and
the rst obstacle is always considered as a mechanical stop during the
opening cycle.
3.2 - Commissioning
Commissioning can only be performed after positive results of all test
phases.
1 Prepare the automation technical documentation, which must contain the
following documents: overall drawing of the automation, electrical wiring
diagram, risk assessment and relative solutions adopted (refer to the rel-
evant forms on our website www.niceforyou.com), manufacturer’s dec-
laration of conformity for all devices used and installer’s declaration of con-
formity.
2 Afxadataplateonthegate,specifyingatleastthefollowingdata:typeof
automation, name and address of manufacturer (responsible for commis-
sioning), serial number, year of construction and CE mark.
3 Before commissioning the automation, ensure that the owner is adequately
informed of all associated risks and hazards.
4.1 - Signals with ashing light
Some devices are set up to give signals by which it is possible to recognise
theoperatingstatusoranyeventualfaults.Ifaashinglightisconnectedtothe
FLASHoutputonthecontrolunit,itwillasheverysecondwhileamanoeuvre
isbeingcarriedout.Ifanyfaultsaredetected,theashinglightwillashmore
quickly; this will be repeated twice, with a 1 second pause between. Table 3a
describes the cause and solution for each type of signal.
