The unit type ES2070CA is universal applicable for automatic monitoring and control of demineralisation plants. Universally implementable for a wide range of control valves, pilot valves but also for solenoid valves. Adaptable to user specific requirements by built-in programmable options. The programmed configuration will be stored into non volatile memory and therefore not be affected by power loss.

  • User operated programming using double row of illuminated LCD display.
  • Display text in English, French, German, Italian or Dutch.
  • Simple control utilising easy to follow symbols.
  • Adaption to user specific requirements by means of options programmable on site.
  • Simple operation by means of a few clear operating symbols.
  • Can be used for various sizes of plant.
  • Capacity values programmable from 1 to 65535 m3
  • Regeneration/rinsing activation by conductivity, time interval, flow, external switching, real time clock or manual control.
  • Time delayed regeneration/rinsing.
  • Control of quantity dependent flushing.
  • Extensive status report facility using information button. Flush control, regeneration/rinsing time, extra program, filter capacity, total quantity of treated water, current input and outputs status, software version, start time interval, time delayed regeneration/rinsing, service telephone number, input and output programming.
  • Large green LED-display showing conductivity, remaining capacity or remaining interval time until next regeneration/rinse.
  • Input of service telephone number.
  • 6 inputs: water meter, level switch for chemical tank cation, level switch for chemical tank anion, level switch for storage tank, regeneration wait and external regeneration start.
  • Integrated conductivity meter with automatic range switching.
  • Conductivity range according to the instrument probe cell constants from 0,1 to 100.000 µS/cm.
  • The instrument probe cell constants programmable from 0,01 to 10,00 cm-1.
  • Manual or automatic temperature compensation.
  • 9 powered relay outputs and 6 relay output with dry contact for control valves, home switches, service valves, circulation pump, suction valves, fill valve cation, fill valve anion, extra programs, regeneration/rinsing procedure, take-off impulse, signalling and flushing.
  • 6 relay outputs (dry contact): extra programs, regeneration/rinsing procedure, take-off impulse, signalling and flushing.
  • Secure from power failure as all data is stored long-term without battery.
  • Real time clock with “lifetime” battery.
  • Efficient micro controller with watchdog, illegal operation code and cycle monitoring.
  • Safeguarded from EMC by galvanic separation between microcontroller and in- and output circuits and also by additional interference suppression filter.
  • Available for wall-mounting.
  • Available (input /output) : 24/24VAC, 115/115VAC, 230/230VAC, 115/24VAC, 230/24VAC, 240/24VAC
