391 - 391EENGLISHGuide for the installerPage 74.2 INSTALLATION DIMENSIONSProcedure for finding the securing position of the operator, usingFig. 5 to help you:measure dimension “A” of the gate and trace a horizontal lineon the graph on the measured value, this line to cross the wholegraph.you will obtain the maximum permissible angular opening accor-ding to dimension “A” of the graph.select the opening range you requireselect dimension “B” so that it intersects the horizontal line (di-mension “A”) inside the required opening range.If dimension “A” permits opening values greater than the ope-ning value selected, the value of dimension “B” can changeup to the maximum permissible opening value.Make sure that the minimum dimension of 450mm in Fig. 5 isobserved.When the operator has been installed, check if dimension “X”in Fig. 5 is minimum 500 mm. If dimension “X” is less than500 mm, run an impact test on the point indicated in Fig. 5,as described in UNI EN12445 standard, and make sure thatthe measured values conform to the specifications of UNIEN 12453 standard.If the thrust values are not within the values specified in UNIEN12453 standard, the zone indicated in figure 5 MUST beprotected with a protective device conforming to the UNIEN12978 standard.The operator was studied and made to be secured vertically(Fig. 6). The operator cannot be installed in other positions.4.3. INSTALLING THE OPERATORWhen you have established dimensions “A” and “B”, you can installthe operator as follows:Loosen by about 1/2 turn the four securing screws of the up-per housing (Fig. 7 ref. /) and withdraw the housing. Set theoperator for manual operation, see paragraph 6.Establish the height of the operator, bearing in mind that:the securing bracket of the curved arm must be in a zonewhere it can be secured to the gate leaf (Fig. 8)the minimum off ground height of the operator must permitsecuring the curved arm and positioning the lower housing (atleast 85 mm, see fig. 8).the lower edge of the rear bracket must be aligned with res-pect to the upper edge of the front bracket (Fig. 9).Secure the rear bracket in the position you had established,using four M8 screws. As you secure the bracket, respect thelay-out in Fig. 10 and check, using a level, if the bracket ishorizontal.To improve water tightness, the external housing covers thesecuring bracket - this prevents the bracket from beingdirectly welded on the pilaster.The rear bracket must be secured on an as smooth as possiblesurface. For masonry pilasters, a counter-plate for walling isavailable as an accessory.Position the operator on the bracket you have just secured,using two M8x100 screws and the relevant nuts - supplied(Fig. 11).Set the operator for manual operation, see paragraph 6.Install the straight arm (Fig. 12) with the supplied screw.Assemble the rest of the arm as illustrated in Fig. 13.For correct operation, tighten the two securing screws (Fig.13 ref. /) and then loosen them by about 1/2 turn to enablerotation without any friction on the arms.Align the arms you have just assembled, pushing in the centralzone until they stop, see Fig. 14 ref. /.There are two stops on the curved arm to facilitate the ali-gning operation.Rest the front bracket on the leaf, Fig. 14 ref. 0.Move back the front bracket by about 20 mm and mark thesecuring holes, Fig. 14 ref. 1.Secure the bracket in the established position using two M8screws.We advise you to secure the bracket with the screws, and••••1.2.•••3.4.5.6.7.8.9.10.11.not weld it to the leaf, in order not to rule out future adjust-ments.Move the bracket by hand and - with the leaf in closing position- make sure that the two arms do not impact each other, asshown in Fig. 14 ref. 0.Take the operator back to the work position - see paragraph6.4.4. WIRING THE OPERATORWhen you have finished securing the operator, you can wire it.There are three holes in the lower part of the operator. They shouldbe used for positioning the cable grippers, for routing the powercables, for connecting accessories and, if necessary, for connectingthe second motor.Install all the three supplied cable grippers with the securingnuts (Fig. 15).Always use the largest cable gripper (Fig. 15 ref. /)If the other two cable grippers are not used, they must beclosed, using the supplied plugs (Fig. 15 ref. 0). Fit the plasticplug in the cable routing hole and close the cable gripperuntil it is tight.Connect the power cable, as shown in Fig. 16. The earthingwire must also be connected. Make sure that the power cablewires are correctly fitted in the ‘comb’ which restrains themFig. 16.If the protective fuse has to be replaced, use a fuse with thefollowing characteristics: 5x20 2A 450V.Wire all the accessories and safety devices, observing therelevant instructions.4.5. POSITIONING THE MECHANICAL STOPSThe 391 operator is supplied standard with opening and closingmechanical stops. This is to facilitate the installation operationsbecause there is no need to construct the mechanical stop ele-ments. The mechanical stops should be fitted in the lower part ofthe operator, coupled to a toothed sector. Installation procedurefor the stops:OPENING MECHANICAL STOPSet the operator for manual operation, see paragraph 6.Manually move the leaf to its opening position.Take the mechanical stop as close as possible to the straightarm and fasten the two securing screws.Make sure that the toothed sector is coupled correctly.CLOSING MECHANICAL STOPUse the closing mechanical stop only in the absence of amechanical stop on the closing leaf.The closing mechanical stop does not guarantee locking theleaf in case of burglary.Set the operator for manual operation, see paragraph 6.Manually move the leaf to its closed position.Take the mechanical stop as close as possible to the straightarm and fasten the two securing screws.Make sure that the toothed sector is coupled correctly.5. AUTOMATED SYSTEM TESTWhen you have made all the necessary electrical connections,power up the system and program the control unit according toyour requirements.Run the test for the automation and for all the connected acces-sories, taking great care when checking the safety devices.Re-locate the upper covering housing, tighten the securing screwsand position the four covering plugs fig. 18 ref. /.Position the lower housing as shown in fig. 18 ref. 0.Hand the “User’s Guide” booklet to the customer and describeits correct operation and use.Point out, to the end user, any residual risks present in theinstallation.12.13.1.2.3.1.2.3.1.2.3.•••••
