![8 WG20 Instructions3.1.1 Operating LimitsChapter 6 "Technical Characteristics" provides the fundamental dataneeded to determine whether all the WG20 components are suitable forthe intended application.In general, WG20 is suitable for the automation of gates featuring leavesup to 4,5m wide, weighing up to 400 kg, with opening angle of up to130° for residential applications.The shape of the gate and the climatic conditions (e.g. presence ofstrong wind) may reduce these maximum limits. In this case it isnecessary to measure the torque needed to move the leaves under theworst conditions, and to compare it to the data provided in the technicalcharacteristics chart for the WG20 gearmotor.3.1.2 Tools and MaterialsMake sure you have all the tools and materials needed to installthe system; make sure that they are in good condition andserviceable according to current safety standards. See examplesin Figure 13.3.1.3 List of CablesThe cables required for the installation of WG20 may vary depending on the type and quantity of devices to be installed; figure 14 shows the cablesneeded for a typical installation; no cable is supplied with WG20.Table 7: list of cablesConnection Cable type Maximum length allowed[A] Power supply line 3x1.5mm2cable 30m (note 1)[B] FLASH light output 2x0,5mm2cable 20m[C] Radio aerial RG58 type shielded cable 20m (recommended less than 5m)[D] ECSBus input/output 2x0,5mm2cable 20m (note 2)[E] STOP input 2x0,5mm2cable 20m (note 2)[F] OPEN input 2x0,5mm2cable 20m (note 2)[G] M1 and M2 motors output 3x1mm2cable 10mWARNING: the cables used must be suitable for the type of installation; for example, an H03VV-F type cable is recommended for indoorapplications, while H07RN-F is suitable for outdoor applications.Note 1 A power supply cable longer than 30 m may be used provided it has a larger gauge, e.g. 3x2.5mm2, and that a safety grounding systemis provided near the automation unit.Note 2 For the ESCbus, STOP and OPEN cables, there are no special contraindications to the use of a single cable that groups together multipleconnections; for example, the STOP and OPEN inputs can be connected to the KS1 selector switch using a single 4x0,5mm2cable.Figure 13B C DA EDDGGFFigure 14](https://usermanual.wiki/MHOUSE-SRL/433TX4.User-Manual/User-Guide-606889-Page-8.png)
![1 Choose the mounting position in accordance with the specifications inparagraph 3.1 "Preliminary Checks".2 Check that the mounting surface is perfectly smooth, vertical andsufficiently compact. WG10 does not come with a mounting system,consequently one will have to be chosen according to the surfacematerial.3 Lay the conduit for the power cable.4 To obtain the rear supports, assemble two brackets and the rear plateas shown in Figure 16.5 To obtain different "C" values (see Figure 12) assemble the brackets andplate as shown in Figure 17.6 To obtain the front support, assemble two brackets and the front plateas shown in Figure 18.7 Remove the back cover of the gearmotors by sliding it in the directionof the arrows.8 Move the leaves to the "gate closed" position.9 Referring to the "B" distance calculated from Table 6, place the rearsupport in the correct position on the mounting surface, Check that thereis a suitable surface at the values in Figure 22, i.e. where the frontsupport is mounted.10 Mark the drill points for the rear support using the support itself as areference point. Drill holes in the mounting surface for 4 anchors [A] witha diameter of at least 8 mm (not included in supply). Fix the plate withsuitable screws [C] and washers [B].WG20 Instructions 9With the exception of the power line that supplies the control unit, therest of the system uses extra-low voltage (approx. 24V); the wiring cantherefore be done by personnel that is not properly qualified, providedthat all the instructions in this manual are carefully observed.After selecting the position of the various devices (refer to figure 1) youcan start preparing the conduits for the electrical cables connecting thedevices to the control unit. The conduits are designed to protect the electrical cables and preventaccidental breakage, which may be caused by the passage of vehicles,for instance.3.2 Preparing the Electrical SystemAlthough the connection of WG20 to the electrical mains is beyond thescope of this manual, we wish to remind you that:• The power supply line must be laid and connected by a qualifiedprofessional electrician.• Alternatively, have a suitably protected 16A "shuko" outletinstalled, where you can plug in WG20.• The electric line must be grounded and protected against shortcircuits; a bipolar disconnection device must also be present withcontact separation of at least 3 mm, which allows the power sup-ply to be disconnected during the installation and maintenance ofthe WG20.3.2.1 Connection to the Electrical Mains3.3 Installation of the Various Devices3.3.1 WG10 gearmotor mountingFigure 15Figure 16Figure 18Figure 19Figure 17 Figure 20ABC](https://usermanual.wiki/MHOUSE-SRL/433TX4.User-Manual/User-Guide-606889-Page-9.png)

![14 WG20 Instructions8 Refer to figure 49 for the electrical extra low voltage connection of thevarious devices to the CL20 control unit terminals.• The terminals have the same colour coding as the correspondingdevices; for example, the grey terminal (OPEN) of the KS1 selectorswitch must be connected to the grey terminal (OPEN) of the controlunit.• For most connections you do not need to observe any polarity; onlyfor the shielded cable of the aerial it is necessary to connect the centralcore and the shield as shown in detail [B]. The cable for the motors mustbe connected as shown in detail [A].• Keep in mind that, to prevent the jamming of the two leaves, thecontrol unit commands the M2 motor to open first, followed by M1 (vice-versa for the closing manoeuvre). Therefore make sure that the motorthat drives the leaf that strikes the mechanical stop is connected toterminal M1 (outer one), while the motor that drives the other leaf mustbe connected to terminal M2.• If only one motor is used (single-leaf gate) it must be connected toterminal M2 while terminal M1 remains free.FL1PH1 PH1 KS1WG10M2WG10M1To facilitate the installation operations, the terminals [B] can be removedas shown in figure 49; make the connections and then re-insert them.When you have completed the connections, use clamps to secure thecables to the appropriate fasteners [C].9 To close the control unit you need to rest the cover on the bottomapproximately 3 cm above the final position, then press it down until itsnaps into place.CBFigure 50Figure 51Figure 49brownyellow/green bluebrownyellow/green blueAB](https://usermanual.wiki/MHOUSE-SRL/433TX4.User-Manual/User-Guide-606889-Page-14.png)
![WG20 Instructions 153.4 Power Supply Connection3.5 Initial checksThe connection of the CL20 control unit to the mains must bemade by a qualified electrician.To carry out tests, insert the plug for CL20 in a power outlet; if neces-sary, use an extension cord.The CL20 control unit must be permanently connected to the mainspower supply for the testing and commissioning operations. This operation must be performed as follows by a qualified electrician:1 Make sure that the plug of the CL20 control unit is not plugged into thepower socket2 Disconnect the power cable from the CL20 control unit power supplyterminal 3 Slacken the collar close to the terminal and remove the cable4 Insert the final power supply cable of the control unit through the collar5 Connect the cable to the terminal of the control unit6 Tighten the collar Figure 52As soon as the CL20 control unit is energized, you should check thefollowing:1 Make sure that the "ECSBus" LED [A] flashes regularly, with about oneflash per second.2 Make sure that the SAFE LED [B] on the photocells flashes (both on TXand RX); the type of flashing is not important as it depends on other factors;what is important is that the LED should not be steadily on or steadily off.3 Make sure that the night light [C] on the KS1 key-operated selectorswitch is on.4 If the above conditions are not satisfied, you should immediately switchoff the power supply to the CL20 control unit and check the cableconnections more carefully. For more useful information see alsochapters 5.5 "Troubleshooting" and 5.6 "Diagnostics and Signals".Figure 55Figure 54BC3.5.1 Recognition of Connected DevicesWhen you have completed the initial checks, the control unit mustrecognize the devices connected to it on the "ECSBus" and "STOP"terminals.1 On the control unit, press the P2 button [C] and hold it down for atleast three seconds, then release the button.2 Wait a few seconds for the control unit to finish recognizing thedevices.3 When the learning procedure is completed, the STOP LED [A] mustremain on, while the P2 LED [B] must go off. If the P2 LED flashes itmeans that an error has occurred: see paragraph 5.5 "Troubleshooting".The connected devices recognition stage can be repeated again at anytime, even after the installation (for example, if an additional photocell isinstalled); just repeat the procedure starting from step 1.

![Istructions WG20 171 Make sure that the provisions contained in chapter 1"WARNINGS" have been carefully observed.2 Using the selector switch or the radio transmitter, test the opening andclosing of the gate and make sure that the leaves move in the intendeddirection.The test should be carried out a number of times to make sure that thegate moves smoothly, that there are no points of excessive friction andthat there are no defects in the assembly or adjustments.3 Check the proper operation of all the safety devices, one by one(photocells, sensitive edges, etc.). In particular, each time a device isactivated the "ECSBus" LED on the control unit flashes for a longer time,confirming that the control unit recognizes the event.4 To check the photocells and make sure that there is no interferencewith other devices, pass a 5 cm diameter, 30 cm long cylinder on theoptical axis, first near TX, then near RX and finally at the mid-pointbetween them and make sure that in all these cases the device istriggered, switching from the active to the alarm status and vice-versa;finally, that it causes the intended action in the control unit, for examplethat it causes the reversal of the movement during the closingmanoeuvre.5 Measure the impact force according to EN 12445 standard. If "motorforce" control is used to assist the system for the reduction of the impactforce, try to find the adjustment that gives the best results.3.6.2 Selecting the Type of Operating CycleThe opening and closing of the gate can take place according to differentoperating cycles:• Single cycle (semiautomatic): the gate opens with a command andstays open until the next command is given, causing it to close.• Complete cycle (automatic closing): the gate opens with a commandand then closes automatically after a short time (for the time, seeparagraph 5.1.1 "Adjusting the Parameters with the Radio Transmitter").To switch from one operating cycle to the other, press the P3 button [B]momentarily; the corresponding LED [A] will light up or go off; if the LEDis off the cycle is "single", if the LED is on the cycle is "complete".Figure 60BA3.7 Testing and commissioningThese are the most important operations, designed to guarantee themaximum safety and reliability of the automation system.The testing procedure can also be used as a periodic check of thedevices that make up the automation.The testing and commissioning operations must be performed byqualified and experienced personnel who must establish whattests should be conducted based on the risks involved, and verifythe compliance of the system with applicable regulations,legislation and standards, in particular with all the provisions ofEN 12445 standard which establishes the test methods for gateautomation systems.3.7.1 Testing3.7.2 CommissioningFigure 61The commissioning operations can be performed only after allthe tests have been successfully carried out. Partialcommissioning or implementation of "temporary" conditions arenot permitted.1 Prepare the technical documentation for the automation, which mustinclude at least: assembly drawing (e.g. figure 1), wiring diagram (e.g.figure 14), analysis of hazards and solutions adopted, manufacturer'sdeclaration of conformity of all the devices installed. For WG20 useAnnexe 1 "EC Declaration of Conformity of the WG20 components".2 Post a label on the gate providing at least the following data: type ofautomation, name and address of manufacturer (person responsible forthe "commissioning"), serial number, year of manufacture and "CE"marking.3 Fill out the declaration of conformity and deliver it to the owner of theautomation system; for this purpose you can use Annexe 2 "ECDeclaration of Conformity".4 Prepare the operating guide and deliver it to the owner of theautomation system; Annexe 3 "OPERATING GUIDE" can be used as anexample.5 Prepare the maintenance schedule and deliver it to the owner of theautomation system; it must provide directions regarding themaintenance of all the automation devices.6 Before commissioning the automation system inform the ownerregarding dangers and hazards that are still existing.](https://usermanual.wiki/MHOUSE-SRL/433TX4.User-Manual/User-Guide-606889-Page-17.png)
![WG20 Instructions 21Normally the recognition of the devices connected to the ECSBus andthe STOP input takes place during the installation stage. However, if newdevices are added or old ones removed, the learning process can begone through again by proceeding as follows:1 On the control unit, press the P2 [B] button and hold it down for at leastthree seconds, then release it.2 Wait a few seconds for the control unit to finish recognizing thedevices.3 When the recognition stage is completed the P2 LED [A] should go off.If the P2 LED flashes it means that something is wrong; see paragraph5.5 "Troubleshooting". 4 After you have added or removed any devices, the automation systemmust be tested again according to the directions contained in paragraph3.7.1 "Testing". 5.3.3 Recognition of Other DevicesBAFigure 635.3.4 Addition of Optional PhotocellsAdditional photocells can be installed at any time on top of thosesupplied with WG20. In an automation system for 2-leaf gates these canbe arranged as shown in Figure 64. To ensure the correct recognition of the photocells by the control unit, theformer must be assigned addresses by means of jumpers. The addressallocation procedure must be performed on TX as well as RX (arranging thejumpers in the same manner), but you must make sure that there are no otherpairs of photocells having the same address.The photocells need to be assigned addresses to make sure that they arecorrectly recognized among the other ECSBus devices, and in order toassign the performed function. 1 Open the shell of the photocell.2 Identify the position where they are installed based on figure 64 andconnect with jumper according to Table 11.The unused jumpers must be stored in their proper compartment forfuture use (Figure 65).3 Perform the recognition stage as explained in paragraph 5.3.3"Recognition of other devices".Figure 64Table 11Photocell h=50cm;activated when gateclosesAPhotocell h=100cm;activated when gate closesBCPhotocell h=50cm;activated when gate opensor closesPhotocell h=100cm; activatedwhen gate opens or closesDPhotocell to the rightactivated when gate opensPhotocell to the leftactivated when gate opensFPhotocell Jumpers Jumpers PhotocellEFigure 65](https://usermanual.wiki/MHOUSE-SRL/433TX4.User-Manual/User-Guide-606889-Page-21.png)
![22 WG20 InstructionsThe CL20 control unit contains a radio receiver for TX4 transmitters;those included in the package are pre-memorized and operative.If you wish to memorize a new radio transmitter you have two choices:• Mode 1: in this "mode" the radio transmitter is used to its fullest extent,i.e. all the buttons execute a pre-established command (the transmitterssupplied with WG20 are memorized in Mode 1). It is obvious that inMode 1 a radio transmitter can be used to command a singleautomation, i.e.:• Mode 2: one of the four commands available can be associated toeach button. This mode, used properly, allows you to command 2 ormore different automations; for example:Each transmitter is, of course, a separate unit, and while some arememorized in mode 1 others can be memorized in mode 2 on thecontrol unit.The overall memory capacity is 150 units; memorization in mode 1 takes upone unit for each transmitter while mode 2 takes up one unit for each button. Warning: since the memorization procedures are timed (10s), youmust read the instructions in the following paragraph before youproceed with their execution.T1 button "OPEN" commandT2 button "Pedestrian gate" commandT3 button "Open only" commandT4 button "Close only" command5.4 Memorization of Radio Transmitters5.4.1 Memorization Mode 11 Press button P1 [B] for at least 3 s.. When the P1 LED [A] goes off,release the button.2 Within 10s, press any button on the radio transmitter to be memorizedand hold it down for at least 3s.If the memorization procedure is successful, the "P1" LED will flash 3times. 3 If there are other transmitters to be memorized, repeat step 2 withinthe next 10s, otherwise the memorization stage will terminateautomatically.Figure 665.4.2 Memorization Mode 2With the memorization in mode 2 of the radio transmitter, any one of thefour commands ("OPEN", "Open partially", "Open only" and "Close only")can be associated to each button.In Mode 2 each button requires a separate memorization stage.1 Delete the remote control system by following procedure "5.4.4Deleting a radio transmitter."2 Press button P1 (figure 66) on the control unit as many times as thenumber corresponding to the desired command, according to thefollowing table: (e.g. 3 times for the "Open only" command).3 Make sure that the P1 LED makes as many quick flashes as thenumber corresponding to the selected command.4 Within 10 s, press the desired button on the radio transmitter to bememorized, and hold it down for at least 2 s.If the memorization procedure is successful, the "P1" LED will flash 3times slowly.5 If there are other transmitters to be memorized for the same type ofcommand, repeat step 3 within the next 10s, otherwise thememorization stage will terminate automatically.1 time "OPEN" command2 times "Pedestrian gate" command3 times "Open only" command4 times "Close only" commandBAT1 button "Open only" commandTasto T2 "Close only" commandTasto T3 "OPEN" commandTasto T4 "OPEN" commandA new radio transmitter can be memorized in the control unit withoutdirectly operating the buttons on it. You need to have an "OLD" pre-memorized operational radio transmitter. The "NEW" radio transmitter tobe memorized will inherit the characteristics of the OLD one, i.e. if theOLD radio transmitter was memorized in Mode 1, the NEW one will alsobe memorized in Mode 1. In this case, during the memorization stageyou can press any key on the two transmitters. If, on the other hand, theOLD transmitter was memorized in Mode 2 you must press the buttonon the OLD transmitter which corresponds to the desired command,and the button on the NEW transmitter to which you wish to associatethat command.Holding the two transmitters, position yourself within the operating rangeof the automation and perform the following operations:1 Press the button on the NEW radio transmitter and hold it down for atleast 5s, then release it.2 Press the button on the OLD radio transmitter 3 times slowly.3 Press the button on the NEW radio transmitter once slowly.At this point the NEW radio transmitter will be recognized by the controlunit and will assume the characteristics of the OLD one.If there are other transmitters to be memorized, repeat all the stepsabove for each new transmitter.5.4.3 "Remote" Memorization](https://usermanual.wiki/MHOUSE-SRL/433TX4.User-Manual/User-Guide-606889-Page-22.png)
![WG20 Instructions 235.4.5 Deleting all the Radio TransmittersWith this operation all the memorized transmitters are deleted. 1 Press the P1 button [B] on the control unit and hold it down.2 Wait until the P1 LED [A] lights up, then wait until it goes off, than waituntil it has flashed 3 times.3 Release the P1 button precisely upon the third flash.4 Wait approximately 4s for the deletion process to be completed; duringthis time the LED will flash very quickly.If the procedure is successful, after a few moments the "P1" LED willflash slowly 5 times. Figure 67BA5.5 TroubleshootingThe following table contains instructions to help you solve malfunctions or errors that may occur during the installation stage or in case of failure.Table 12Symptoms Probable cause and possible solutionThe radio transmitter does not emit anysignal (the LED [A] does not light up) • Check to see if the batteries are exhausted, if necessary replace them (page 34)The manoeuvre does not start and the"ECSBbus" LED [B] does not flash • Make sure that the power cord is properly plugged into the mains outlet • Check to see if the fuses [E] or [F] are blown; if necessary, identify the reason for the failure and then replacethe fuses with others having the same current rating and characteristics..The manoeuvre does not start and theflashing light is off• Make sure that the command is actually received. If the command reaches the OPEN input, thecorresponding "OPEN" LED [D] must light up; if you are using the radio transmitter, the "ECSBus" LED mustmake two long flashes.The manoeuvre does not start and theflashing light flashes a few times• Make sure that the STOP input is active, i.e. that the "STOP" LED [C] comes on. If this does not happen,check the devices connected to the STOP input.·• The photocell test which is performed at the starting of each manoeuvre is not successful; check thephotocells, also according to Table 13 on page 24.The manoeuvre starts but it is immediatelyfollowed by a reverse run• The selected force is too low to move the leaves. Check to see whether there are any obstacles; ifnecessary increase the force as described on page 19.The manoeuvre is carried out but theflashing light does not work• Make sure that there is voltage on the flashing light's FLASH terminal during the manoeuvre (beingintermittent, the voltage value is not important: approximately 10-30Vac); if there is voltage, the problem isdue to the lamp; in this case replace the lamp with one having the same characteristics.EACB DFFigure 685.4.4 Deleting a Radio Transmitter If a radio transmitter is available, this operation allows you to delete it.If the transmitter is memorized in Mode 1, a single deletion stage issufficient: just press any button at point 3. If the transmitter is memorizedin Mode 2, one deletion stage is needed for each memorized button.1 Press and hold down button P1 [B] (Figure 67) on the control unit.2 Wait until the P1 LED [A] lights up, then, within three seconds:3 Press and hold down for at least three seconds the button of the radiotransmitter to be deleted.If the radio transmitter has been deleted, the P1LED will flash quickly five times. If the LED flashes slowly just once, itmeans that the deletion has not taken place because the transmitter isnot memorized4 If there are more transmitters to be deleted, repeat step 3 within tenseconds while pressing button P1, otherwise the deletion stage willterminate automatically.](https://usermanual.wiki/MHOUSE-SRL/433TX4.User-Manual/User-Guide-606889-Page-23.png)
