4292P

Lifting Magnet Controllers

Type 4292P Compact Controller for Scrap Yards

Specification/Price Sheet • August 2008

YARDMASTER PUP

Description

The Type 4292P Yardmaster Pup Controllers incorporate heavy-dutytime proven components arranged to provide optimum control of your lifting magnets.

A mechanically rugged high thermal capacity discharge varistor assembly is permanently connected in parallel with the magnet and provides a safe discharge path for the stored magnetic energy.

With Yardmaster Pup magnetic controllers induced voltage cannot return to the line, permitting rectified power supplies to be used without the added expense of special protective loads or bypass circuits.

Features

Automatic Discharge.

Rated 5-50amps DC.

Front-Wired,Front-Removablecomponents.

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-Thermalcapacity varistor discharge path.

Peak magnet induced voltage limited to under 700 volts.

Long electrical contact life.

Minimum maintenance.

Dribble control standard on 115V & 230V controllers.

Ventilated Indoor/Outdoor NEMA 3R Enclosure.

Application

The Type 4292P Yardmaster Pup Controllers are suited for many uses from light to medium scrap handling applications. They may be used with all types and makes of DC lifting magnets.

Automatic Discharge Type Controllers

The Type 4292P Yardmaster Pup Automatic Discharge Type Lifting Magnet Controllers provide a fast and clean release of magnet loads by applying full voltage reverse current to the magnet. The full voltage reverse current feature permits the operator to promptly return for another lift.

The drop contactor is under the control of the operator’s Master Switch and the Discharge Sensor Module (DSM). When the 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 discharge 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 current to the magnet and begins the adjustable time reverse current cycle. After completion of the timed reverse current cycle the drop relay and the drop contactor are de-energized.
