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

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-A34
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. Short Description
The panel instrument DAG-A34 is a 4-digit device for Pt100 sensors and a visual
limit value monitoring via the display. The configuration happens via three front
keys. An integrated programming interlock prevents unrequested changes of the
parameter and can be unlocked again via an individual code.
The electrical connection happens on the rear side via plug-in terminals.
Selectable functions like e.g. the recall of the min/max-value, an impedance
matching up to 20°C and a direct change of the limit value in operating mode
complete the modern device concept.

6. Assembly
Please read the Safety advice on page 12 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!

7. Electrical Connection
DAG-A340 with supply of 230 VAC DAG-A343 with supply of 24 VDC
DAG-A344 with supply of 115 VAC
DAG-A342 with supply of 24 VAC
Advice:
The galvanic isolation in devices with temperature sensors, that do not have a
galvanic connection to an extrinsic potential, can be cancelled by a bridge from
terminal 3 to 4 and thus stabilise the device against external failures.
Devices with a supply of 230 VAC need to connect terminal 3 to signal ground
230 VA

or
115 VAC or
24 VAC

8. Function, Description and Operation
Operation
The operation is divided into two different levels.
Menu Level
Here it is possible to navigate between the individual menu items.
Parameterization level:
The parameters stored in the menu item can be parameterized here.
Functions that can be adjusted or changed are always indicated with a flashing of
the display. Adjustments made at the parameterization level should be always
confirmed by pressing the [P] key to save them.
However, the display automatically saves all adjustments and then switches to
operation mode if no further keys are pressed within 10 seconds.

9. Setting up the device
9.1 Switching on
Once the installation is complete, you can start the device by applying the current
loop. Check beforehand once again that all the 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 start-up sequence, the device switches
to operation/display mode.
9.2 Standard parameterization:
To be able 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.

9.3 Programming interlock RUN
9.4 Extended parameterization
By pressing the [▲] & [▼] keys during standard parameterization for one second,
the display switches to the extended parameterization mode. Operation is the same
as in standard parameterization.
