Program List and Explanations
Examples of metering devices that are driven time proportional are
solenoid valves, peristaltic pumps.
Dosing is controlled by the operating time.
5.3.2.32.20 Cycle time: duration of one control cycle (on/off change).
Range: 0–600 sec.
5.3.2.32.30 Response time: Minimal time the metering device needs to react.
Range: 0–240 sec.
5.3.2.32.4 Control Parameters
Range for each Parameter same as 5.2.1.40, p. 60
Examples of metering devices that are pulse frequency driven are
the classic membrane pumps with a potential free triggering input.
Dosing is controlled by the repetition speed of dosing shots.
5.3.2.32.21 Pulse frequency: Max. pulses per minute the device is able to re-
spond to. Range: 20–300/min.
5.3.2.32.31 Control Parameters
Range for each Parameter same as 5.2.1.40, p. 60
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.
Range: 1–20 %
5.3.2.32.4 Control Parameters
Range for each Parameter same as 5.2.1.40, p. 60
5.3.2.32.1 Actuator = Time proportional
5.3.2.32.1 Actuator = Frequency
5.3.2.32.1 Actuator = Motor valve
