5.3.2.22 Parameter: Choose on of the following process values.

DIS

Sample Flow
5.3.2.32 Settings
:
Choose the respective actuator:

Time proportional

Frequency

Motor valve
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 5.2.1.43, p. 76
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 5.2.1.43, p. 76
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 5.2.1.43, p. 76
5.3.2.32.1 Actuator = Time proportional
5.3.2.32.1 Actuator = Frequency
5.3.2.32.1 Actuator = Motor valve
