2.Note
Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
The instruction manuals on our website www.kobold.com are always for
currently manufactured version of our products. Due to technical changes, the
instruction manuals available online may not always correspond to the product
version you have purchased. If you need an instruction manual that corresponds
to the purchased product version, you can request it from us free of charge by
email ([e-mail]) in PDF format, specifying the relevant invoice
number and serial number. If you wish, the operating instructions can also be
sent to you by post in paper form against an applicable postage fee.
Operating instructions, data sheet, approvals and further information via the QR
code on the device or via www.kobold.com
The devices are only to be used, maintained and serviced by persons familiar
with these operating instructions and in accordance with local regulations
applying to Health & Safety and prevention of accidents.
When used in machines, the measuring unit should be used only when the
machines fulfil the EC-machine guidelines.
3.Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:
The standard delivery includes:
•Electronics for measuring and monitoring model: ZED-K and DF-…KLxxx
4.Regulation Use
Any use of the Evaluation Electronics, model: ZED-K and DF-..KLxxx, which
exceeds the manufacturer’s specification, may invalidate its warranty. Therefore,
any resulting damage is not the responsibility of the manufacturer. The user
assumes all risk for such usage.

ZED-K
page 4 ZED-K K11/0523
5.Operating Principle
The evaluation unit changes the frequency signal of the pickup into a flow
reading and into a scalable analogue signal.
The top display line of the double-spaced display shows the flow value with
measuring unit and the bottom line a bargraph indicator proportional to the
measuring value.
The two relays with floating output changeover contacts continuously monitor
the flow values. Switching point, hysteresis, a window point, and switch on or off
delay can be set separately for each relay. The switching points can also be set
directly by using the control keys without having to change over into the menu. A
red LED indicates the switching status.
The analogue output is optionally available as current output with 0(4)...20 mA
or as voltage output with 0...10 V. The menu languages can be switched
between 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.
A MIN/MAX reading memory determines the extreme readings of the flow. The
display of the readings and the resetting are achieved by using the keys without
having to change into the menu. Resetting by using the keys can also be
blocked.
The set parameters can be protected against unauthorized alteration by using a
password function.

they have been chosen for any input.
The parameter can only be changed, if the security code has been
entered correctly! The message „locked“ will appear if the input has
not been activated.

USER CALIBRATION
Menu Item
Function / Description
CAL Freq* Calibrate by entering frequency and flow.
In the menu item CAL Freq the bottom line always shows the current pulse value of the
User calibration.
Calibration process:
a) FlowVal Enter nominal flow value of the sensor. > (e) press >
b) FlowUnit Enter unit for flow value. > (e) press >
c) Freq.Val. Enter nominal frequency > finish with (e).
The new pulse value of the User calibration is calculated from these three values and saved
as user calibration for the flow measurement, e.g. 20.2757 pls./litre.
CAL Vol. Calibration process using impulse counting and volume input (cc procedure).
In the menu item CAL Vol. the bottom line always shows the current pulse value of the
User calibration.
Calibration process:
a) PulseCnt measures number of impulses
(e) press > start counter (impulses are counted) > (e) press > stops counter.
b) Vol.Val Enter measured volume value > (e) press.
c) Vol.Unit Enter unit for volume value > finish with (e).
The pulse value of the User calibration is calculated from these three values and is saved as
the user calibration for the flow measurement, e.g. 3900,5 pls./L.
*) CAL Freq – Only possible with ZED devices.
Note: With ZED devices it is necessary to enable the device-specific
parameter input in the menu Item SecCode in the menu SERVICE in order
to activate the CAL-USER function.
Note: If the new pulse ratio will be used for measurement, than the menu
item fFaktor in the menu group General Settings must be setted to USER
calibration.
