1. APPLICATION
Large-size digital displays of DL type are destined to display measured values o set values through the
communication interface. Taking in consideration the application of 7-segment LED displays they are
destined to be installed inside buildings.
The 100 mm digit height ensures a good readout from the distance of 40 m.
They find application in office accommodations , production workshops, in production management
rooms as information about production parameters, state of machines or devices.
The displayed value is transmitted from external devices working in MODBUS standard. The display
is working as the network „master”. The basic display version includes three digits and the unit, in two
rows or three rows.
It is possible to make the display in the configuration required by the customer.
2. DISPLAY SET
The display set is composed of:
- DL11, DL12 or DL13 display 1 pc
- Suspension holder 2 pcs
- Diskette with software 1 pc
- User’s manual 1 pc
- Guarantee card 1 pc
When unpacking the display, please check whether the type and execution code on the data plate
correspond to the order.
3. BASIC REQUIREMENTS, OPERATIONAL SAFETY
Symbols located in this service manual mean:
WARNING!
Warning of potential, hazardous situations.
Especially important. One must acquaint with this before connecting the digital display.
The non-observance of notices marked by these symbols can occasion severe injuries of
the personnel and the damage of the device.
CAUTION!
Designates a general useful note. If you observe it, handling of the device is made easier.
One must take note of this, when the device is working inconsistently to the expectations.
Possible consequences if disregarded!
In the security scope the digital display meets the requirements of the EEC
Low-Voltage Directive (EN 61010 -1 issued by CENELEC ).
Remarks concerning the operator safety:
1. General
nThe DL large displays are destined to be mounted in accordance with customer’s requirements.
nNon-authorized removal of the required housing, inappropriate use, incorrect installation or
operation creates the risk of injury to personnel or damage to equipment. For more detailed
information please study the User’s Manual.
nAll operations concerning transport, installation, and commissioning as well as maintenance must
be carried out by qualified, skilled personnel and national regulations for the prevention of
accidents must be observed.
nAccording to this basic safety information, qualified, skilled personnel are persons who are
familiar with the installation, assembly, commissioning, and operation of the product and who
have qualifications necessary for their occupation.

2. TransporT, sToraGe
nPlease observe the notes on transport, storage and appropriate handling.
nObserve the climatic conditions given in Technical Data.
3. InsTallaTIon
nThe DL digital display must be installed according to the regulation and instructions given in this
User’s Manual.
nEnsure proper handling and avoid mechanical stress.
nDo not bend any components and do not change any insulation distances.
nDo not touch any electronic components and contacts.
nDevices may contain electrostatically sensitive components, which can easily be damaged by
inappropriate handling.
Do not damage or destroy any electrical components since this might endanger your health!
4. elecTrIcal connecTIon
nBefore switching the device on, one must check the correctness of connection to the network.
nIn case of the protection terminal connection with a separate lead one must remember to connect
it before the connection of the device to the mains.
nWhen working on live devices, the applicable national regulations for the prevention of accidents
must be observed.
nThe electrical installation must be carried out according to the appropriate regulations (cable
cross-sections, fuses, PE connection). Additional information can be obtained from the user’s
guide.
nThe documentation contains information about installation in compliance with EMC (shielding,
grounding, filters and cables). These notes must be observed for all CE-marked products.
nThe manufacturer of the digital display or installed devices is responsible for the compliance with
the required limit values demanded by the EMC legislation.
nDo not connect the digital display to the mains through an autotransformer.
nThe RS-485 socket serves only to connect devices working with the MODBUS protocol.
5. operaTIon
nMeasuring systems including DL digital displays, must be equipped with protection devices
according to the corresponding standard and regulations for prevention of accidents.
nAfter the display has been disconnected from the supply voltage, live components and power
connections must not be touched immediately because capacitors can be charged.
nThe housing must be closed during operation.
nThe protection degree ensured by the housing is defined as IP40 and IP10 from the connection
side.
6. MaInTenance and servIcInG
nPlease observe the manufacturer’s documentation.
nRead all product-specific safety and application notes in this User’s Manual.
nBefore taking the device housing out, one must turn the supply off.
nThe removal of the device housing during the guarantee contract period may cause its
cancellation.
4. DESIGN DESCRIPTION AND INSTALLATION
The display housing is made of profiles and aluminium sheets, painted in black colour.
The frontal surface is made of polycarbonate as an anti-reflexive glass.
The protection degree ensured by the housing is defined as IP40.
The view and overall dimensions of DL11, DL12 and DL13 displays are presented on fig. 1, 2 and 3.
The design enables to fix the display on a wall.

5. ELECTRICAL CONNECTIONS
Caution: the installation and display connections should be carried out by a qualified
personnel.
The connection of supplying wires and interface should be carried out only in accordance with the
user’s manual. In case of inconsistent connections with the assigned connectors the display can be
damaged. For the connection of control signals one must apply a wire coil in a shield.
In case of an environment with a low level of noise it is admissible to apply a wire coil non-shielded.
Caution: in case of a sudden change of the ambient temperature, dew may occur and it is forbidden
to connect the display to the supply. It is recommended before mounting the display which changes
suddenly its temperature, to wait at least 60 minutes before the first start.

Before carrying out changes of the given parameter, it
s recommended to carry out the read-out of the current
configuration and modify the chosen parameter.
Transmission default parameters of the DL1 display:
- address in the network: 1
- transmission mode: RTU8n2
- baud rate: 9600 bit/sec.
Transmission parameters can be freely changed by
the user. It is recommended to write new and previous
transmission parameters.
The view of the main window of the DL1 program is
presented on the window design.
6.1. Connection configuration
In order to configure connections, one must choose
the option „Connection configuration” from the main
program window. Then, the dialog window presented
on the design will start.
After choosing connection parameters, one can check
the transmission correctness, choosing the option
„Check” or close the window in order to a further work
with the program.
Moreover, the user can also choose the option „Change
parameters” serving to change parameters - see
section 6.2. „Change of transmission parameters..
6.2. Changing transmission parameters”
In order to change connection parameters, one must
choose „Connection configuration” and next, choose
the option Change Parameters in the dialog window
Connection Configuration.
Caution: The change of transmission parameters
can be only made when the connection is correctly
configured..
In the dialog window Connection Change, the user
must give required connection parameters and choose
Change in order to change connection parameters or
Cancel, to resign of introducing changes.
6. CONFIGURATION OF THE DL DISPLAY
The DL11 display is default configured to the display of values being in the register 7500.
The change of display parameters is carried out through the suitable modification of values in
configuring registers. To change parameters, one can use any program destined to read-out and
write registers in MODBUS RTU networks.
Together with the display, a program for the display configuration is delivered, allowing the
modification of all accessible parameters.
