   MANUAL MODEL 140         SPEC SHEET MODEL 140         CUTSHEET MODEL 140 

Quick Install Model 140


 

 

FEATURES

  • Use this Controller for cooling towers.
  • Removable power cord and receptacles for simple conduit installations.
  • Scheduled feed, which can use two relays for biocides or other chemicals.
  • One (1) water meter input, conductivity input, flow switch input, and 4-20 mA output are all standard features.
  • Designed with a single circuit board for better reliability and lower cost.
  • Large open shallow enclosure for easy wiring.
  • The enclosure is rated NEMA 4X.
  • Power selector switch for 115 or 230 vac operation.
  • Heavy-duty stainless steel domed numeric keypad and illuminated graphical display allow for quick and easy programming.  Steel domed switches improve the tactile sensing and life expectancy of the keypad.
  • LED indicators for power, alarm and relay status.

 


 

BENEFITS

  • Easy to program with the Lakewood plain English, intuitive, and user friendly menu interface.
  • Single circuit board design improves reliability.
  • No add-on options.  4-20 mA output and biocide features are standard.
  • Multiple methods of chemical feed for application flexibility.
