Dosing
By using the dosing function via the user display manually dosing is configurable. The volume
„Dosing Batch“ and the „Dosing Time“ are freely adjustable. When the „Dosing Time“ is set to zero the
timer control is inactive. A dosage can be started and stopped with the menu function keys „Start“ and
„Stop“ or can be started by the digital input.
Setting range “Dosing Batch”: 0 – 3500 Liters
Setting range “Dosing Time” 0 –30000 Seconds
Default setting “Dosing Batch”: 0 Liters
Default setting “Dosing Time”: 3 Seconds
Pulse value
This determines for what flow volumes an output pulse will be emitted.
Choose configuration such as to neither exceed the maximum ouptput frequency of the FFU (10 kHz)
nor the maximum input frequency of the control.
Example: 2.0 ml/pulse
This means: a pulse is emitted every 2.0 ml.
Setting range: 0.1 ... 3000.0 ml/pulse, in 0.1 ml/pulse steps
Default setting: 1.0 ml/pulse
Digital output Q1
Digital output Q1 may be used as pulse output, empty pipe detection, limit control or negative flow
(flow direction). By using display it is possible to switch between npn and pnp logic.
Setting area: off, pulse output, empty pipe, lower limit, upper limit, negative flow
Digital output Q2
Digital outputs Q2 may be used as pulse output, empty pipe detection, for switching dosing valve,
limit control or flow direction control. The npn or pnp logic can be chosen.
Example 2: FFU pnp-out connected to a counter
Connecting output 2 to external counter
Setting area: off, pulse output, empty pipe, lower limit, upper limit, negative flow
Media
The Flowcont Un dispose of a medium matrix with up to 8 interpolation values. Different medias can
be managed in the sub menu “Media”. Matrix values can be saved and if needed be loaded for different
medias.
