1. Selter CE ELECTROMAGNET USER S MANUAL This user s manual is the document that goes with the lifting magnet since its construction until its dismantling and it is an integral part of it It is essential reading this manual carefully before using the lifting magnet This manual is an integral part of the lifting magnet and should be accessible to the staff responsible for the use and maintenance The operator and maintenance manager must know the contents of this manual Maintaining the essential characteristics of the type of equipment described SELTER reserves the right to make any changes in the components details and accessories which considers appropriated to improve the product or for any constructive or business requirements at any time and without compromise to update this publication ATTENTION ALL RIGHTS ARE RESERVED It is prohibited to reproduce any part of this manual in any form without written permission from SELTER S A APPLICATION This equipment can have different application depending on the needs The most common application is the lifting of pieces and materials The risk associated with the lifting magnet is mainly a sudden release caused by Incorrect magnetization of the piece described in paragraph 3 Power outage In case this electromagnet is used to lift pieces or materials it will be considered as a lifting accessory according Directive 2006 42 EC Selter security applies a coefficient 3 Th

3. is means that the maximum load is the third part of the effective load shedding as the static test describes in the certificate of inspection IMPORTANT While disconnecting the electromagnet is possible that the piece has a magnetic remanence That is the piece can retain some residual magnetism and it does not releases easily from the electromagnet Depending on needs it can make a demagnetized cycle which removes any remaining magnetism in the piece See Technical Service Selter ATTENTION Make sure the piece is separated from the electromagnet before lifting the electromagnet in a vacuum There is the risk that the piece has remanence remains attached to the electromagnet and falls unexpectedly CAUTION This equipment generates magnetic fields Careless handling can cause accidents and injuries Read the following recommendations before handling e Avoid the presence of iron elements near the magnetic zone ie beams cranes doors etc e Be especially careful when unpacking the load with iron objects ex knives scissors screwdrivers pliers etc e When manipulating two or more devices place them separately at a safe distance between them so they do not attract each other e To release clamped magnets slide one over the other to prevent pinching fingers e Electronic equipment eg pacemakers hearing aids computers monitors watches measuring instruments and control etc and containers of information eg f
4. loppy disks credit cards magnetic tapes etc can be distorted or damaged by a magnetic field Keep these items at a suitable distance from the magnetic systems CAUTION The electromagnet works by passing a current through the internal coils When the current is interrupted the electromagnet stops the magnetization The electromagnet needs a supplies DC appropriate voltages for the magnetization and demagnetization process if necessary In case of mounting the electromagnet in a machine with incorporated unit control ensure that it supplies the correct voltage DC to the electromagnet and it has enough power see electrical characteristics in electromagnet When the electromagnet runs out of power power failure cable breakage the magnetization stops and the piece is fixed only by the residual magnetism If the electromagnet is connected to a SELTER electronic control this has a relay for safety functions alarms activation stop machine INSTALLATION All SELTER electromagnets are sent with grinded top plate and perfectly flat and are ready to use To install the electromagnet follow the instructions below Carefully clean the top plate of the electromagnet and check for any damage received during transport Put the electromagnet in the work area Remember to place the magnet so as not to impede the output of the power cable Depending on the model the electromagnet can incorporate a feed inlet with wired hose a
