RK Series™ Three Phase Duplex 4-20mA Control Panel

Three Phase, Duplex 4-20mA Continuous Level Control System for Pump Control and System Monitoring

rk series three phase duplex 4-20mA diagram

The RK Series™ Three Phase Duplex 4-20 mA continuous level sensing panel is designed to control two 208/230/460 VAC three phase pumps in water and sewage installations. The protective inner door features panel operating status indicators, LCD display, control buttons and provides access to the pump motor protection switches. The controller provides for alternation of the pumps for even usage. Panel is designed for 4-20mA input and 2-float backup control.

COMPONENTS

  1. NEMA 4X enclosure rated for indoor or outdoor use
  2. Lockable latches for added safety
  3. Motor protective switches provide the adjustable overload, branch circuit protection, and pump disconnect
  4. IEC motor contactors control the pump motor load by switching the electrical lines
  5. Multitap transformer (208/230/460 VAC primary) provides 115 VAC control/alarm voltage
  6. Primary transformer voltage fuses provides transformer short circuit protection
  7. Terminal Strip field wiring of incoming power, backup floats, submersible level transmitter, and pumps
  8. Ground lugs
  9. Molded inner door provides access to circuit breakers, and mounting location for indicators, display, and control buttons
    1. Digital 32-character backlit LCD display
    2. Green LEDs indicate control and alarm circuit power
    3. Red LEDs indicate when either control or alarm fuse is blown
    4. Backup Float Status LED indicator (green=low level redundant off, red=high level)
    5. Amber LED indicates backup float control mode activated
    6. Green Pump Run LEDs indicate when pump is called to rung. Pump Hand/Run buttons operate the pump manually
    7. Alarm Test/Silence reset button
    8. Red LED indicate high water alarm
  10. 360° red alarm beacon for visual alert
  11. Piezo audible alarm (not shown)
  12. Alarm silence touch pad (not shown)
