  • Page 103 AMI Soditrace Program List and Explanations As control Signal outputs can be used for driving control units. We distinguish different kinds of controls: output  P-controller: The controller action is proportional to the devia- tion from the setpoint. The controller is characterized by the P-Band.

  • Page 108 AMI Soditrace Program List and Explanations 5.3.2.1 Function = Control upwards or control downwards The relays may be used to drive control units such as solenoid valves, membrane dosing pumps or motor valves. When driving a motor valve both relays are needed, relay 1 to open and relay 2 to close the valve.
  • Page 109 AMI Soditrace Program List and Explanations 5.3.2.32.1 Actuator = Motor valve Dosing is controlled by the position of a motor driven mixing valve. 5.3.2.32.22 Run time: Time needed to open a completely closed valve. Range: 5–300 Sec. 5.3.2.32.32 Neutral zone: Minimal response time in % of the runtime. If the re- quested dosing output is smaller than the response time, no change will take place.
