the adjusting of the air-gap is carried out by working on the fixing nuts and locknuts of the electro magnet references 9 and 11 shown above the adjusting of the air-gap must always be carried out by working contemporarily on these elements to obtain a precise and fine adjusting 1 lean the magnet against the armature plate surface bring the nuts 9 and 11 against the magnet unscrew the nuts 9 and 11 up to moving the magnet towards the outside enough to be able to insert the thickness metal sheet position the thickness metal sheet near the fixing stud bolts between magnet and armature plate as in the side picture leaving it inserted for all the adjusting adjust the thickness of the air-gap according to the values in chart 3 screwing/unscrewing the nuts 9 and 11 with the appropriate fixed hexagonal key with a criss-crossed sequence up to feeling a slight resistance on the thickness gauge lock the nuts 11 contrasting with the proper nut 9 so not to move the magnet applying the locking values written in chart 2 second line with a dynamometrical key check the correct value of the air-gap with the thickness gauge blade bigger of 0,1mm than thickness used in the previous step and make sure it doesn t enter in the air-gap positioning of the thickness gauge for a correct measuring of the air-gap position the thickness metal sheet corresponding to the magnet surface and not on the external rim of the container or on the resin tapping limit of resetting of the air-gap it is compulsory to reset the air-gap when it reaches the maximum value of chart 3 paragraph 3.1.1 2 3 4 5 3.3

connection research the coils through a tester verify electrical continuity by setting measurement on the tester star connection triangle connection 3.5 servicing a frequent inspection of the brake to check all its parts is necessary as the wear depends on a series of factors and mainly on the inertia of the load the speed of the motor and the frequency of intervention verify the main parts of the brake group and if necessary replace them with original temporiti spare parts servicing may be roughly determined according to what is pointed out on the site www.temporiti.it 3.5.1 replacement of the disk the disk must be replaced after a consumption of 1,5 mm of the fiction material per ring that is when the minimum values of the total thickness are reached metal thickness ring thickness written in chart 5 proceed replacing the disk following the opposite of the steps reported in paragraph 3.1.3 strictly providing after the operation to the adjusting of the air gap as explained in paragraph
