Relay: Operational mode:
Each relay (A and B) can be assigned to be driven by
sensor A's or sensor's B selected measurement (conductivity, resistivity or TDS) or temperature
Relay functions:
Control: settings for high/low phasing, setpoint, deadband, overfeed timer, off delay, and on delay
Status: not configurable; relay only activates when a "fail" diagnostic condition exists
Temperature compensation:
-20 - 200 °C automatic or manual with selection for temperature compensator (Pt1000 RTD or Pt100 RTD); Linear % per °C slope, built-in ammonia temperature properties table, built-in natural water temperature properties table, or no compensation
to automatic or manual with selection for temperature compensator (Pt1000 RTD or Pt100 RTD); Linear % per °C slope, built-in ammonia temperature properties table, built-in natural water temperature properties table, or no compensation
Авариен сигнал:
Alarm: settings for low alarm point, low alarm point deadband, high alarm point, high alarm point deadband, off delay, and on delay
Бр. канали:
2 sensor A or B’s measured values or temperatures can be separately displayed, or all four measurements can be displayed together on
one screen. Both outputs are displayed together on a screen. Also, a calculated sensor A and B measurement can be displayed
