5. Assembly
Please read the Safety instructions on page 13 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.

7. 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.

8. Setting up the device
8.1 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.
8.2 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.

8.3 Programming interlock RUN
8.4 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.

9. 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

10. Functional principle of the switching points
Limit value exceedance
“
High ”
The setpoint S1-S2 is “off”
below the threshold and “on”
on reaching the threshold.
Limit value undercut
“low”
The setpoint S1-S2 is
“on” below the
threshold and switched
“off” on reaching the
threshold.
Alarms / optical switching point display
An activated switching point can be optically indicated by flashing of the 7-segment
display.

13. Safety advice
Please read the following safety advice and the assembly chapter 2 before
installation and keep it for future reference.
Proper use
The DAG-A3V-device is designed for the evaluation and display of sensor 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-A3V-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 6A 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.

DAG-A3V
page 16 DAG-A3V K06/1222
• Any electrical connection deviating from the connection diagram can endanger
human life and/or can destroy the equipment.
• 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 insulated potentials within one complex need to be placed on a
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

14. Error elimination
Error description Measures
1. The unit permanently indicates overflow. • The input has a very high measurement, check the
measuring circuit.
• With a selected input with a low voltage signal, it is only
connected on one side or the input is open.
• Not all of the activated switching points are
parameterised. Check if the relevant parameters are
adjusted correctly.
2. The unit permanently shows underflow. • The input has a very low measurement, check the
measuring circuit .
• With a selected input with a low voltage signal, it is only
connected on one side or the input is open.
• Not all of the activated switching points are
parameterised. Check if the relevant parameters are
adjusted correctly.
3. The word "HELP " lights up in the
7-segment display.
• The unit has found an error in the configuration memory.
Perform a reset to 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 6 and
set it back to its delivery status.

15. Disposal
Note!
 Avoid environmental damage caused by media-contaminated parts
 Dispose of the device and packaging in an environmentally friendly manner
 Comply with applicable national and international disposal regulations and
environmental regulations.
Batteries
Batteries containing pollutants are marked with a sign consisting of a crossed-out
garbage can and the chemical symbol (Cd, Hg, Li or Pb) of the heavy metal that
is decisive for the classification as containing pollutants:
Cd1 Hg2 Pb3 Li4
1. „Cd" stands for cadmium
2. „Hg" stands for mercury
3. „Pb" stands for lead
4. „Li" stands for lithium
