Description
The compact and powerful MGC2000 generator
control system features a unique, simple-to-install
and setup design and enhanced operation.
The control method for the MGC2000 may be
specified for using either the AS3000 Autostart
automatic controller or the 518APH electrically
tripped annunciator method.
The system is available in two basic configurations:
MGC2000 features mechanical gages:
- MGC2000-A Automatic Control: with
Murphy’s AS3000 Generator Controller.
- MGC2000-M Manual Control: with
518APH annunciator control.
Both configurations include standard AC
voltmeter, AC ammeter, and frequency meter.
Available for single-phase, standard three-phase,
and three-phase, re-configurable generators.
MGC2000E features electric gages:
- MGC2000E-A Automatic Control: with
Murphy’s AS3000 Generator Controller.
- MGC2000E-M Manual Control: with
518APH annunciator control.
Both configurations include standard AC volt-
meter, AC ammeter, and frequency meter.
Available for single-phase, standard three-phase,
and three-phase, re-configurable generators.
Features
• Dynamic design allows for easy installation
and full operation flexibility.
• 1/4 inch quick disconnect terminations
• Shock mount assemblies to minimize damage
• AC voltmeter and ammeter
• Phase selector switch
• Frequency meter: 45-65hz
• Optional hourmeter; DC Voltmeter;
DC ammeter
• First-out fault shutdown and indication
(AutoStart models only) of low oil pressure,
high temperature and auxiliary inputs
• Inputs can be from engine-mounted fault
switches or panel-mounted SWICHGAGE ®
instruments.
• Magnetic pickup or generator AC speed
sensing (AutoStart models only). For automat-
ic crank release and overspeed fault shutdown.
Speed calibration is automatic–adjustment free.
Additional switch inputs allow optional remote
control of crank disconnect and overspeed fault.
• Generator AC Hz meter output: 0-1 mA.
• User-friendly: Well-thought-out routine for
faster and easier set up.
• Interfaces with existing equipment: functions
seamlessly with many other Murphy instru-
ments and controls (AutoStart models only).
