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 machinery directive.
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:
 Digital Indicating Unit model: DAG-M4F
4. Regulation Use
Any use of the device, 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. Brief description
The panel meter DAG-M4F evaluates pulses in many different ways and shows
the result in the 5-digit LED-display. Available options are: frequency coverage
with optional filters, summate of pulses or display values via time, detection of
a rotational speed or collection of a position via an incremental encoder. The
results can be monitored via alarm conditions and can be displayed onto the
optional switching point. Furthermore, the results can be freely scaled on an
optional analog output and relayed to a control system. The device can be
operated directly by Namur sensors, 3-wire sensors, switching/slider contacts,
incremental encoders (HTL-/TTL-output) or TTL-signals. Via the 4 navigation
keys on the front, the device can be adjusted onto different kind of applications
and later on different functions of the device can be controlled. Numerous
applications can be realized with this device, like e.g. tachometer, revolution
counter, flowmeter, dosing equipment, filling capacity meter, baking time meter
of a baking oven, flying knife, position evaluation, position surveillance, flow
rate surveillance, acoustic discharge measurements and so on. By use of the
integrated, configurable functions like permanent min/max-recording,
averaging, frequency filter, setpoint setting, threshold value recording via alarm
system, 30-points-linearisation, mathematic charging and many more, you
receive a universal applicable modern system for your demands in measuring and
control technique.

6. Assembly
Please read the following Safety advices on page 25 before installation and keep
this user manual for future reference.
1. After removing the fixing elements, insert the device.
2. Check the seal to make sure it fits securely.
3. Click the fixing elements back into place and tighten the clamping screws by
hand. Then use a screwdriver to tighten them another half a turn.
CAUTION! Tor torque should not exceed 0.1 Nm!
The dimension symbols can be exchanged before installation via a channel
on the side!

7. Electrical connection
Type DAG-M4F8 supply 100-240 VAC, DC ± 10%
Type DAG-M4F7 supply 10-40 VDC, galv. Isolated, 18-30 VAC
Advice
If Namur sensors with a nominal voltage of approx. 8 V are used, then a sensor supply of 12
VDC is needed. For devices with a sensor supply terminals 4 and 18, as well as terminals 3
and 19 need to be galvanically connected in the device.
Connection examples
Below you find some connection examples with practical applications:

8. Function and operation description
Operation
The operation is divided into three different levels.
Menu level (delivery status)
This level was designed for the standard settings of the device. Only menu items
which are sufficent to set the device into operation are displayed. To get into the
professional level, run through the menu level and parameterize prof under menu
item RUN.
Menu group level (complete function volume)
Suited for complex applications as e.g. linkage of alarms, setpoint treatment,
totalizer function etc. In this level function groups which allow an extended
parameterization of the standard settings are available. To leave the menu group
level, run through this level and parameterize uloc under menu item RUN.
Parameterization level
Parameter deposited in the menu item can be parameterized here. Functions,
that can be changed or adjusted, are always signalized by a flashing of the
display. Settings that are made in the parameterization level are confirmed with
[P] and thus saved. Pressing the [O]-key („zero-key“) leads to a break-off of the
value input and to a change into the menu level. All adjustments are saved
automatically by the device and changes into operating mode, if no further key
operation is done within the next 10 seconds.

9. Setting up the device
9.1 Switching-on
Once the installation is complete, start the device by applying the voltage supply.
Before, check once again that all electrical connections are correct.
Starting sequence
For 1 second during the switching-on process, the segment test (8 8 8 8 8) is
displayed, followed by an indication of the software type and, after that, also for 1
second, the software version. After the starting sequence, the device switches to
operation/display mode.

9.2 Standard parameterization (Flat operation level)
To parameterize the display, press the [P]-key in operating mode for 1 second. The
display then changes to the menu level with the first menu item TYPE.
