Description

AS3020 Cooling Tower ControllerThe unit type AS3020 is universal applicable for automatic monitoring and control of cooling tower plants. The controller is equipped with an conductivity meter without temperature meter. There are three possible stages : “Service”, “Flush” and “”Flush wait”. This unit can monitor conductivity and several inputs e.g. level switches, low pressure switch, exceeded pressure and stop. 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.

Features

  • User operated programming using double row of illuminated LCD display
  • Display text in English, French, German or Dutch.
  • Adaption to user specific requirements by means of options programmable on site
  • Extensive status report facility using information button.
  • 2 inputs : tank full and tank empty
  • 2 powered realy outputs: Inlet valve (fused 8A), Flush valve (fused 8A).
  • 1 relay output (dry contact) : Alarm.
  • Secure from power failure as all data is stored long-term without 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) : 12VDC/12VDC, 24VDC/24VDC, 24VAC/24VAC, 115VAC/115VAC, 230VAC/230VAC
