FEATURES

  • Two water meter inputs, 4-electrode conductivity sensor input, flow switch input, four relay outputs, and Power On/Off switch in a NEMA 4X enclosure are all standard features.
  • Removable power cord and receptacles for simple conduit installations.
  • Includes four relays for bleed, chemical feed, and alarms; expandable up to 12 relay outputs.
  • Includes three security levels to prevent unauthorized programming access.
  • Includes two languages; English/Spanish are standard.
  • Heavy-duty stainless steel domed numeric keypad and large illuminated graphical display allow for quick and easy programming.  Steel domed switches improve the tactile sensing and life expectancy of the keypad.

 


 

BENEFITS

  • Easy to program with the Lakewood plain English, intuitive, and user friendly menu interface.
  • Expandable in the field with the use of the Nodes for additional inputs, such as additional sensor inputs or additional outputs such as relays, 4-20 mA, LonWorks, and remote communications.
  • Able to feed chemicals by multiple feed schemes including by feed schedule, setpoint control, percent of blowdown, percent of time, and by water meter.
  • Able to bleed based on setpoint or by water meter.
  • Includes sensor fouling compensation and alarm.
