Specifications

System Specifications:

• Three front panels mounted at 15, 60, and 90 degrees
• Rear panel is recessed to protect fault switches
• Size: 20″ wide, 191/4″ deep, and 143/4″ high
• Training Center Weight: 40 pounds
• Accessory Package Weight: 8 pounds
• Protective cover for the unit is included

Circuit Protection and Safety:

• Main breaker protects the 115-volt primary circuit of the control transformer and 115-volt drive motor
• 24-volt circuit breaker with zero delay protects all wiring
• Fast acting, zero delay control circuit breaker “trips” to interrupt the circuit if an an accidental electrical overload occurs

Circuit Connections:

• Identical to circuits actually used in industrial plants
• Interconnect panel consists of:
  • 82 heavy-duty tip jacks
  • 32 stacking type patch cords

Fault Switches:

• 40 three-position toggle switches mounted on the rear panel
• Switches used to set “short circuit” or “open circuit” faults into panel circuits

Other Components:

• Six industrial type, 24 VDC pilot lights
  • Connected across relay, timer, and motor starter coils to indicate when coils are energized
• Eight industrial type pushbuttons on the front panel
• Two selector switches: One three-position and one two-position
• Two control circuit relays mounted behind panel
• One adjustable time delay relay mounted behind panel
• Two Motor Starter Relays mounted behind the panel
• Test Timer mounted on back panel for timing proficiency development exercises
• Panel mounted 200k potentiometer
• One 24 VDC reversing motor
• Patterned disc, visible through a front window, rotates at varying speeds to duplicate the operation of a conventional motor connected to the control circuit
