TYPE 4010 REVERSING-PLUGGING CONTROL
FOR BRIDGE OR TROLLEY SERVICE
Simple, easy-to-understand system has
smooth, timed or frequency responsive
acceleration and plugging control of wound rotor
motor used for reversing drives on travel
motions for all types of cranes. The motor is
started with all the rotor resistance in the circuit.
Contactors in the controller short out the
external rotor resistance in timed or frequency
responsive steps under control of a master
switch, to provide smooth and rapid
acceleration. During reversing, a frequency
sensitive plugging relay prevents all of the
secondary resistor contactors from closing until
the motor is practically at rest. This keeps all of
the external rotor resistance in the circuit during
reversal to provide safe, controlled stopping. Type 4010 reversing-plugging control panels
are suitable for use with AC Wound Rotor
Motors on crane bridge or trolley travel drives.
These panels can also be used on any
reversing drive that is non-overhauling.
Panels are arranged for use with separate AC
or rectifier operated DC brakes.
Suitable for all NEMA and CMAA service
classes.
Recommended for: NEMA service Class I,
CMAA service Class A1, C, D, E, F.
