Residual magnetism varies largelydepending on workpieces (material, shape, mass, etc.). It is therefore necessary to set the demagnetizing time (few seconds to over ten seconds)suitable for particular workpieces. The most effective demagnetizing patterns for each set time have been programmed in the computer to startautomatic demagnetization by button operation. After studying whether the output required for magnetization may be constant or must be variable,select a model suitable for the rating of the electromagnetic chuck.■Selecting a rectifier①Select a suitable rectifier for installation in combination with a separatedemagnetizer. (Connection diagram 2) Be sure to observe the followingconditions: Voltage of electromagnetic chuck≧output voltage of rectifierCurrent of electromagnetic chuck < output current of rectifier Electromagnetic chuck 90 VDC, 0.8 AOutput of rectifier 90 VDC, 1 A②When selecting a Chuck Master or rectifier dedicated todemagnetization having an output voltage exceeding the rated voltage(90 V) of the electromagnetic chuck, special attention must be paid tothe selection of the current capacity.〈Example〉Electromagnetic chuck 90 VDC, 4.5 ARectifier output 0 to 120 VWith the above combination, the maximum current of the rectifier is:120V4.5A×=6A, thus a rectifier having output capacity 5A cannot be used.90V③Other considerations should include fluctuation of the voltage in theoperation area. Select an output capacity with sufficient allowance.■Connection diagram■Selection based on electric capacity Name Model Power SourceElectroChuck MasterChuck Masterdedicated todemagnetizationSelector switchRectifierEH-V305AEH-VE305ASingle-phase100 VAC?220 VAC50/60 Hz■Selecting a demagnetizerThe use of a demagnetizer requires a rectifier. Select a rectifier, referringto“Selecting a rectifier.”The demagnetizer cannot be used together with the Electro ChuckMaster.The manual demagnetization types, Model S-2A and ESR-5A, cannot beconnected to equipment other than a rectifier.DC Output Demag.Chuck RatingRectifier DemagnetizerVoltage Current ControlVoltage Max.
