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.
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:
•Counter Electronic model: ZED-Z or flowmeter incl. Counter Electronic
4. Regulation Use
Any use of the Counter Electronic, model: ZED-Z, 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.

5. Operating Principle
The evaluation unit changes the frequency signal of the pickup into a 3(4)-digit
flow reading with selectable measurement unit (top display line), and into a
scalable analogue signal. The flow quantity is added up in a part quantity meter
and a total quantity meter and then displayed in the bottom line of the screen.
The quantity meter’s units of measurement are selectable.
The two relays with floating output changeover contacts continuously monitor if
the freely adjustable limits are exceeded or fallen short of. Here, it is possible to
choose between threshold value and window monitoring.
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.
Alternatively, it is also possible to monitor the quantity meter to see if it is
exceeded. A red LED indicates with 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 Parameter names can be shown in the
menu in 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. When using analogue output 0 – 10 V the customer must put a
jumper between the terminals 7 and 8.
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. If the maximum set flow (exceeded range) is exceeded, it will be shown
on the display.
The set parameters can be protected against unauthorized alteration by using a
password function.
Range of functions
Quantity meter and flow meter with digital display, switch and analogue output:
•Measurement and display total, part and flow quantities
•Free scaling using input of frequency and measured value
•Control input for part quantity reset
•2 switching outputs, freely programmable as flow monitor or for monitoring
the part and total quantity
•Analogue output 0(4)-20 mA oder 0-10 V
•MIN/MAX memory

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 USER-ABGLEICH 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.
