5. Operating Principle
The evaluation unit changes the frequency signal of the pickup into a 3(4)-digit
flow reading with adjustable scale (topline of display), and a scalable analogue
signal. The dosage is displayed in the bottom line of the display. The unit of
measurement can be selected.
Included are two relays with floated output changeover contacts for various
functions. The relay (S1) can be used to execute the flow monitoring, total volume
monitoring, fine dosage or the pump control.
When the flow is being continuously monitored, it checks if the freely adjustable
limits are exceeded or fallen short of. A choice can be made between threshold
value and window monitoring. Switching point, hysteresis, window point, and
switch-on or switch-off delay can be set as desired. If monitoring of the total
volume is selected, a check is made to see if the adjustable quantity limit is
exceeded.
The dosage relay (S2) switches on when the dosage process starts, and then
switches off again, once the dosage has flowed through. The dosage process can
be interrupted by using the Start/Stop switch. By taking a correction quantity into
account, it is possible to take any special features or conditions of the system into
account. By entering a fine dosage, the bypass valve can be controlled with the
relay (S1). A red LED indicates the relay’s switching status.
The Analogue output is available as a current output with 0(4)...20 mA or a
voltage output with 0...10 V. The parameter names in the menu can be displayed
in either German or English. If used where the flow readings change rapidly, the
display can be pacified and the analogue reading averaged by switching on some
software. If the maximum set flow (exceeded range) is exceeded, it will be shown
on the display. The set parameters can be protected against unauthorised
alteration using a password function.
Range of functions
Dosage and flow meter with digital display, switch and analogue output:
•Measurement and display of dosage, total and flow Quantities
•Free scaling using Teach-In or input of frequency and measured value
•Interval counter (number of dosing processes)
•2 control inputs
•1 dosage output
•1 switching output, freely programmable as flow monitor
or for monitoring the total quantity
•Analogue output 0(4)-20 mA or 0-10 V

The following parameterizations must be made:
Settings on the UMF2B / UMF3 / UMC4 transmitter (see corresponding
operating instructions):
−Enter customer password 0002 (UMF2B, UMF3: Chapter 13.2.1, UMC4:
7.2.2.1).
−In the function class "Pulse output" / "Pulse or frequency output" set the
pulse output to frequency output (UMF2B, UMF3: Chapter 13.6.1; UMC4:
7.2.8.1). Select the unit l/min (UMC4: kg/min) in the function class "Flow" /
"Flow unit". Any other unit can be selected. When calculating K0 later in the
ZOK, however, it must first be converted to l/min. - Read out the end value
in l/min (kg/min) in the function class "Flow" / "Flow end value". If the flow
rate is the same as the final value, the converter outputs 1000 Hz.
−With short filling times, the smallest possible time constant should be set
(UMF2B: Chapter 13.4.1; UMF3: Chapter 13.4.2; UMC4: 7.2.4.1).
−The filter is switched off (UMC4: "weak") (UMF2B: Chapter 13.4.5; UMF3:
Chapter 13.4.1; UMC4: 7.2.4.5). In this way, the measured value can follow
a change in flow rate as quickly as possible. This makes the flow rate
indication in the display more restless, but this is not relevant for the
accuracy of the dosing.
−The low flow rate should be set to a small value, e.g. 1%, so that no pulses
are counted when the medium is standing still (UMF2B: Chapter 13.4.2;
UMF3: Chapter 13.4.3; UMC4: 7.2.4.2).
Settings on the ZED-D:
See chapter 7.8
FlowVal = End value of the UMFx in l/min (or kg/min)
FlowUnit = l/min
Freq.Val = 1000 Hz

ZED-D
ZED-D K11/0522 page 9
Function check:
Activate the simulation for the frequency output on the UMF2B, UMF3 or UMC4
converter:
- Select function class "Simulation" / "Simulation specification Q / direct" =>
"Direct".
- Set the frequency to 1000 Hz under "Simulation direct pulse output".
- Switch on the simulation under "Simulation off / on"
The ZED-D must now display a flow rate that is equal to the final value of the
UMF2B (UMF3, UMC4)
Please note:
If the end value is exceeded, there is a risk that at a frequency above 1100 Hz,
the frequency transmission between the converter and ZED-D will no longer
function properly and pulses will be lost. Please also observe the display of the
UMF2 (UMF3, UMC4) during a sample filling, whether an error "Pulse output
overdriven" or "Current overdriven" is reported. In this case, the final value in
UMF2 (UMF3, UMC4) must be adapted and the FlowVal parameter recalculated
in the ZED-D. The measuring range of the UMF2B (UMF3, UMC4) should be
adapted to the maximum expected flow rate in order to make good use of the
frequency range of 1000Hz. If, for example, the maximum flow rate is 30 l / min,
the end value should be set to e.g. 33 l/min (10% reserve) to allow the end value
to be exceeded slightly.
