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-M4V
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 instrument DAG-M4V is a 5-digit device for direct current / direct
voltage signals and a visual threshold value monitoring via the display. The
configuration happens via four keys at the front. The integrated programming
interlock prevents unrequested changes of parameters and can be unlocked
again with an individual code. Optional the following functions are available: a
supply for the sensor, a digital input for triggering of Hold (Tara), two analog
outputs and interfaces for further evaluating in the unit. With help of the galvanic
insulated setpoints (optional), free adjustable limit values can be controlled and
reported to a superior master display. The electrical connection is done via plug-in
terminals on the back side. Selectable functions like e.g. the recall of the min/max-
value, an averaging of the measuring signals, a nominal presetting or setpoint
presetting, a direct threshold value regulation during operation mode and further
measuring setpoints for linearization, complete the modern device concept.

6. Assembly
Please read the Safety advice on page 35 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! The torque should not exceed 0.1 Nm!
The dimension symbols can be exchanged before installation via a channel
on the side!

Connection examples
Below please find some connection examples that show practical applications.
For devices with current inputs / voltage inputs without sensor supply.
DAG-M4V devices
With current respectively voltage input in combination with a 24 VDC sensor supply.

8. Description of function and operation
Operation
The operation is divided into three different levels.
Menu level (delivery status)
This level is for the standard settings of the device. Only menu items which are
sufficient 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 here be parameterized. 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. By pressing the [0]-key it leads to a break-off of the value input and to
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, you can 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.
