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:
 Digital Indicating Unit for Panel Mounting model: DAG-A14
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 instrument DAG-A14 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
Type DAG-A143000R
supply of 24 VDC
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.

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 [▲] & [▼] buttons during standard parameterization for one
second, the display switches to the extended parameterization mode. Operation is
the same as in standard parameterization.

10. Reset to default values
To return the unit to a defined basic state, a reset can be carried out to the default
values. The following procedure should be used:
Switch off the power supply
Press button [P]
Switch on voltage supply and press [P]-button until „ - - - -“ is shown in the display.
With reset, the default values of the program table are loaded and used for
subsequent operation. This puts the unit back to the state in which it was supplied.
Caution! All application-related data are lost.

14. Safety advice
Please read the following safety advice and the assembly chapter 6 before
installation and keep it for future reference.
Proper use
The DAG-device is designed for the evaluation and display of Pt100 signals.
Danger! Careless use or improper operation can result in
personal injury and/or damage to the equipment.
Control of the device
The panel meters are checked before dispatch and sent out in perfect condition.
Should there be any visible damage, we recommend close examination of the
packaging. Please inform the supplier immediately of any damage.
Installation
The DAG-device must be installed by a suitably qualified specialist (e.g. with a
qualification in industrial electronics).
Notes on installation
• There must be no magnetic or electric fields in the vicinity of the device,
e.g. due to transformers, mobile phones or electrostatic discharge.
• The fuse rating of the supply voltage should not exceed a value of 0.5 A N.B.
fuse.
• Do not install inductive consumers (relays, solenoid valves etc.) near the
device and suppress any interference with the aid of RC spark
extinguishing combinations or free- wheeling diodes.
• Keep input, output and supply lines separate from each other and do not lay
them parallel with each other. Position “go” and “return lines” next to one
another. Where possible use twisted pair. So, the best measuring results can
be received.
• Screen off and twist sensor lines. Do not lay current-carrying lines in the
vicinity. Connect the
screening on one side on a suitable potential equaliser (normally signal
ground).
• The device is not suitable for installation in areas where there is a risk of
explosion.
• Any electrical connection deviating from the connection diagram can
endanger human life
• and/or can destroy the equipment.

DAG-A14
DAG-A14 K05/0622 page 17
• The terminal area of the devices is part of the service. Here electrostatic
discharge needs to be avoided. Attention! High voltages can cause dangerous
body currents.
• Galvanic isolated potentials within one complex need to be placed on an
appropriate point (normally earth or machines ground). So, a lower disturbance
sensibility against impacted energy can be reached and dangerous potentials,
that can occur on long lines or due to faulty wiring, can be avoided.

15. Error elimination
Error description Measures
1. The unit permanently indicates
overflow.
• The input has a
very high
measurement,
2. The unit permanently shows
underflow.
• The input has a very low measurement, check
the measuring circuit .
• The input is open.
3. The word "HELP " lights up in the
7-segment display.
• The unit has found an error in the
configuration memory. Perform a reset on the
default values and re-configure the unit
according to your application.
4. Program numbers for parameterising
of the input are not accessible.
• Programming lock is activated
• Enter correct code
5. "Err1" lights up in the 7-segment
display
• Please contact the manufacturer if errors of
this kind occur.
6. The device does not react as
expected.
• If you are not sure if the device has been
parameterised before, then follow the steps as
written in chapter 10 and set it back to its
delivery status.
7. The temperature value is unstable. • Please check the possibility to set aside the
galvanic insulation for a discharging of failures
as described under chapter 7 „Electrical
connection“. Before make sure that the
possible metal sensor is separated from the
sensor element.
