Page 5: Basic Safety Measures
2.2.1 Basic Safety Measures • Do not put your hand into the openings of the metal separator. Mechanical forces which may cause heavy injuries occur on switching of the pneumatic gate. • Prior to any maintenance works, disconnect the equipment from compressed air and power. -
Page 6: Application And Qualification
Application and Qualification Use for Intended Purpose The MESEP® VA digital removes metallic contaminations from bulk materials. These materials, for example, can be plastic granules, dry powder, rice or similar products from different industries. Free-fall metal separation: The unit is integrated in the existing conveying system. To guarantee reliable separation, the material must not be dropped into the device from a height of more than 600 mm. -
Page 7: Examples Of Application
semi-finished and finished products industries etc. The 8217 type metal separators are used amongst others at places where long equipment running times are required. The high sensitivity of the separators guarantees shortest possible machine downtimes and metal-free final products according to nominal sensitivity. Especially there where the final products cost effectiveness comes from the quantity, the unit pays for itself within short time. -

• modifying the metal separator without permission by Pulsotronic SKS GmbH & Co. KG to for the use for other purposes. Consider that after a modification you may be regarded as manufacturer of the metal separator - with all guaranty consequences. - Page 9 the MESEP digital works without problems. • Red LED „VALVE FAULT“ After the last metal detection the separating drum did not reach the end position. The MESEP digital can not separate the detected material. As soon as the separating drum switches perfect again after a further metal detection, the error report goes out automatically.

During normal operation, a change of the DIP switch positions is not required. Funktion DIP 1 Working frequency of 295 kHz 290 kHz... -
Page 12: Sensitivity Table
3.6 Sensitivity Table The currently selected sensitivity is indicated by means of the four horizontally arranged yellow LEDs at the front plate. Example: After pressing of F1+ or F2- buttons the diodes 3 and 4 light for approximately 5 seconds. The actual values of response sensitivity is 2.5 mm. This corresponds to stage 6, i.e. -

For non-magnetic high-grade steel applies: The FE St37 value from the table, multiplied by 1.5, is the approximate response sensitivity of a high-grade steel bullet. Notes for the values of sensitivity Notice: The sensitivity values apply to the centre of the detection ring, because, for technical reasons, there is the lowest sensitivity. -

Page 15: Operation Instructions
Operation Instructions • The metal separator should be permanently on. This will provide maximum lifetime of the electronic circuits. Failure Protection of the Metal Separator The metal separators mains inlet is protected against disturbing influences. Increased operation safety and additional protection against failures is reached applying the following measures: •... -

Page 17: Technical Description
* Connection monitoring Units with this function have an additional solenoid valve and a return spring in the pneumatic cylinder. In case of compressed-air failure, the return spring brings the sorting gate into the NOT OK position. The second, additional solenoid valve acts only if main voltage is available. -
Page 18: Selection Of Operation Variants
Selection of Operation Variants The printed circuit board behind the front plate includes a potentiometer. It is used to adjust the separation time after metal detection. At supply, the device is adjusted for an average separation time of approx. 1 sec . The separation time should be adjusted according to quality and flow speed of the material to be handled. -
Page 19: Notes For The Values Of Sensitivity
Notes for the values of sensitivity Notice: The sensitivity values apply to the centre of the detection ring, because, for technical reasons, there is the lowest sensitivity. The measuring method analyses not only height and width, but also the depth of the metallic particle. This leads to a fact which applies to all conventional, analog metal-separating systems: Not the weight, but the size of the particle is decisive for the detection accuracy. -
Page 20: Product Effects - Disturbing Product Properties
• coil for generation of a high frequency magnetic field • a following evaluation electronics If metal or other conductive material move through the ring coil, the magnetic field is influenced. This influence changes the level of the electric current. This process is called electromagnetic induction. - Page 21 The electrical resistance of distilled water is unlimited, provided that it is pure, distilled water. Distilled water contains neither salts nor minerals. Dissolved salt changes the electric resistance so much that the solution gets electrically conductive. Similarly, conductive properties can be observed in some plastics due to additives. Raw materials are more or less conducting.
