Settings: Choose the respective actuator:
 Time proportional
 Frequency
 Motor valve
Actuator = Time proportional
Examples of metering devices that are driven time proportional are
solenoid valves, peristaltic pumps.
Dosing is controlled by the operating time.
Cycle time: duration of one control cycle (on/off change).
Range: 0–600 sec.
Response time: Minimal time the metering device needs to react.
Range: 0–240 sec.
Control Parameters:
Range for each Parameter same as
Actuator = Frequency
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.
Pulse frequency: Max. pulses per minute the device is able to re-
spond to. Range: 20–300/min.
Control Parameters:
Range for each Parameter same as
Actuator = Motor valve
Dosing is controlled by the position of a motor driven mixing valve.
Run time: Time needed to open a completely closed valve
Range: 5–300 Sec.
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%
Control Parameters:
Range for each Parameter same as
Function = Timer:
The relay will be activated repetitively depending on the pro-
grammed time scheme.
Mode: Operating mode (interval, daily, weekly)
