Hubbell Industrial Controls, Inc. 4292 Lifting Magnet Controllers Type 4292 Compact Controller for Scrap Yards Specification/Price Sheet • August 2008 • Replaces Jan 2008 Description Automatic Discharge Type Controllers The Type 4292 Yardmaster Controllers incorporated heavy-duty time proven components arranged provide Automatic Discharge Type optimum control of your Lifting Magnet Controller lifting magnets. provides a fast and clean A mechanically rugged release of mag-net loads high to The Type 4292 Yardmaster thermal by applying full voltage capacity discharge varistor assembly is permanently connected in charge a parallel safe dis- for the path stored magnetic energy. With Yardmaster magnet controllers, induced voltage cannot return to the line, permitting rectified power supplies to be used without or bypass circuits. Application The Type 4292 Yardmaster Controllers are suited for many uses from light scrap handling to the handling of heavy billets or plates. It may be used with all types and makes of DC lifting magnets. to the magnet. The full voltage permits the operator to promptly return for another lift. Features • • • • • the added expense of special protective loads current re-verse current feature with the magnet and provides reverse • • • • • • Automatic Discharge Rated 250 VDC @ 5-100 amps Front-Wired Front-Removable components Mechanically interlocked “Lift” and “Drop” NEMA rated mill duty contactors Permanently connected 700V discharge path completely independent from the line that protects magnet and generator High-Thermal capacity varistor discharge path Peak magnet induced voltage limited to under 700 Volts Long electrical contact life Minimum Maintenance Dribble control - Standard Ventilated indoor/outdoor NEMA 3R enclosure The drop contactor is under the control of the operator’s Master Switch and the dis-charge sensor module (DSM). the When operator’s Master Switch signals the magnet controller to drop the load, the “Lift” contactors (L) open. The stored magnet energy is dissipated in the dis-charge varistor. When the discharge voltage declines to approximately 300V, the DSM energizes the drop relay (DR) which in turn enables the drop contactor (D) to close applying full voltage reverse cur-rent to the magnet and begin the adjust-able time reverse current cycle. After the completion of the timed reverse cycle the drop relay and drop contactor are deenergized. Model Numbers & Prices Part Number Control Circuit Voltage List Price (Sch.
