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 (info.de@kobold.com) 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

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.

7. Operation and Menu Structure

7.1 General

Only the menu items of which the lines are marked in the selection matrix (in the

right position) in grey colour, are available in the respective instrument version.

Italic written values in the menu structure are blinking in the display, if

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.

7.2 Function of the control keys

Operating mode >Measure< :

- Press briefly: a) Display total quantity, then

Display corresponding scale unit or

b) Reset status reports.

- Press for 3 sec: Switch to operating mode >Parameterise<.

- Press briefly: Display min. flow value (MIN value memory).

- Press for 3 sec: Enter switching point for Relay S1 s1SPoint

(only if parameter SPdirect is set to “yes”).

- Press briefly: Display max. flow value (MAX value memory).

- Press for 3 sec: Enter switching point for Relay S2 s2SPoint

(only when parameter SPdirect is switched to “yes”).

Press for 3 sec: Sets min. and max. value memory to flow value

(only when parameter fMMReDir is switched to “yes”).

Operating mode >Parameterize<:

- Press briefly: a) Open parameter group or

b) Change parameter (go lower in menu level) or

c) Adopt value input.

- Press for 3 sec: Abort input and go back one

menu level.

- Press briefly: a) Select parameter group or parameter or

b) Reduce selected number by 1 or

c) Select list value (e.g.... L/m, L/h, m3/m, ...).

- Press briefly: a) Select parameter group or parameter or

b) Increase selected number by 1 or

c) Select list value (e.g.... m3/m, L/h, L/m, ...).

Note: If no button is pressed for 20 seconds during parameterising, the

instrument automatically switches back into >measuring< mode.

GENERAL SETTINGS

Menu Item Parameter / Function Explanation / Values / Other

Language Select menu language

German or English

fUnitFS * Measuring unit for flow

measurement

mL/s, mL/m, L/s, L/m, L/h, m3/m, m3/h,

GPM, GPH, UU/s, UU/m, UU/h

fValueFS * Maximum measuring range value

for flow measurement

Range = 0,00...99,9..._100...9999

fMinVal * Minimum measuring range value

for flow measurement

Basis is fValueFS and fUnitFS

If the level drops below this, the flow indicator goes to 0.

fPls/rev* Impulse per sensor wheel

revolution

Number of impulses per revolution of the sensor wheel or the like

Necessary for long-term period averaging if the readings per revolution vary.

The function is switched off when the input value is 1.

fJumpVD* Flow switch value for attenuation

cut-off

Value in %, basis is fValueFS and fUnitFS.

Attenuation does not function if the switch value is 0%.

fOverflV * Flow overflow value (overflow)

Value in %, basis is fValueFS and fUnitFS.

If exceeded, an M100 report is generated and faded in, alternating

with the flow indicator.

The report is saved and can be reset by briefly pressing the

PGM key.

fFactor Select pulse ration

Selection of works calibration or user calibration.

(only for devices Model DF-...ZLxxx and Model-...ExxR)

UserUnit. Special volume unit

Customer-specific special unit UU.

The value entered corresponds to the number of litres of the special unit, e.g.

in the case of the unit Barrel the factor would for example be 115.6271.

SPdirect Activation of direct input switching

point

yes: Direct input of switching points s1SPoint and

s2SPoint is possible using the keys (default).

no: The switching points can only be set in the menu .

*) Only for ZED devices: Device-specific parameter, is only visible after activation in the SecCode menu item in the SERVICE

menu group, and can be changed.
