1 Operation instruction for explosion protected control panels
Application and standards
This instruction manual applies to explosion protected control panels of type of protection types
below. This apparatus is only to be used as defined and meets requirements of EN 60 079 particularly EN60 079-14 "electrical apparatus for potentiality explosive atmospheres". It can be used
in hazardous locations which are hazardous due to gases and vapours according to the explosion
group and temperature class as stipulated on the type label. When installing and operating the
explosion protected distribution and control panels the respective nationally valid regulations and
requirements are to be observed.
General Instructions
The control panel has to have a back-up fuse as stipulated. The mains connection must have a
sufficient short circuit current to ensure safe breaking of the fuse. To achieve an impeccable and
safety device operation, please take care for adept transportation, storage and mounting, as well
as accurate service and maintenance. Operation of this device should only be implemented by
authorised persons and in strict accordance with local safety standards. The electrical data on the
type label and if applicable, the "special conditions" of the test certificate PTB 98 ATEX 1488 are
to be observed.
For outdoor installation it is recommended to protect the explosion protected distribution and control panel against direct climatic influence, e.g. with a protective roof. The maximum ambient temperature is 40°C, if not stipulated otherwise.
Intrinsically Safe Circuits
Erection instructions in the testing certificates of intrinsically safe apparatus are to be observed.
The electrical safety values stipulated on the type label must not be exceeded in the intrinsically
safe circuit. When interconnecting intrinsically safe circuits it is to be tested, whether a voltage
and/or current addition occurs. The intrinsic safety of interconnected circuits is to be ensured. (EN
60079-14, section 12)
,
Safety Measures: to read and to comply
Work on electrical installations and apparatus in operation is generally forbidden in hazardous locations, with the exception of intrinsically safe circuits. In special cases work can be done on nonintrinsically safe circuits, on the condition that during the duration of such work no explosive atmosphere exists.
Only explosion protected certified measuring instruments may be used to ensure that the apparatus is voltage-free. Grounding and short circuiting may only be carried out, if there is no explosion
hazard at the grounding or short circuit connection.

2 Message display TA125
2.1 Short Description
The field text display TA125 indicates arbitrary messages, warnings or hints in the hazardous area zone 1. It’s large
(58 x 244 mm2), reflective display with a figure height of 15 mm can easily be read up to a distance of five meters.
The display is organised into 4 rows with 40 characters per row.
The TA125 receives the messages for instance from a PC or DCS located in safe area. The interface TI125 serves
as intrinsically safe barrier and power supply. It can be equipped with several bus modules (RS232, RS485, RS422,
Profibus DP, Interbus and Modbus). The distance to the TA125 could be up to 300 meters with a data rate of 38,4
kbit/s. Use wire with a bigger diameter for longer distances.
It is possible to connect many text display to one bus (theoretical up to 255). Each one with a different text content.
Additionally the TA125 has an intrinsically safe passive alarm output. With this it is possible to connect a further
alarming device. With the three digital inputs you can acknowledge a message or an alarm or you can request further information on the spot in hazardous area.
The TA125 stores up to 32 kByte of messages in an internal EEprom. You can program the stored messages with
the bundled windows software “TEXT LINK”. There are two ways to display the stored texts: the serial interface or
applying a defined bit pattern to binary address inputs of the TI125 (option).

n is the number of the digits of the device address. If n=0
the address input is disabled.
If you use more than one Textdisplay on the same bus,
you must identify the display device by its device address
The watchdog timer determinates a broken data wire. If
the TA125 gets no data in watchdog time, the TA125 will
show “ No connection to host !”. After receiving data
again the message disappears.
If “Yes” is entered all settings will be confirmed and the
configuration menu will be left. Otherwise the menu starts
from the beginning.
4.5.1 Data format
The default data format of the serial interface is 8 bit. That can be changed to 7 data bits.
The user may change the parity, stop bit and serial speed settings too.
4.5.2 Protocol
The serial interface can manage several receive protocols, see the table below:

The data contains text data and format characters for instance Text page recall, show variable etc. The header contains the display device address.
4.5.3 Device address
It is possible to connect several display devices to one bus. In that case every device get its
individual device address (0* ... 255) in menu tag (10). This address must be sent in the
head of each data transmission to select the right device.
The display devices TA125 understand the address “0” as Broadcast. That means that
every display device on the bus receives and displays the message.
Enter the address length at menu tag (9). If you use the transmission protocol (1), (3) or (5)
choose “0” as address length.
4.5.4 Twelve binary inputs
The TA125 has three binary inputs, to acknowledge an alarm for instance. If a signal on input x occurs the TA125 sends immediately the ASCII character x to the host. If the user releases the button the TA125 sends the ASCII “0” 30(hex).
With serial RS232 / RS485- interface it is not possible to use this inputs, if more than one
unit is connected to the network.

4.6.2 Display modes
From the software version 2.0 the TA125 has two different display modes. The general
mode the TA125 works according to ISO/IEC 6429. With this general mode all text functions of the TA125 can be used.
Additionally works the TA125 in compact mode. In the mode the TA125 gets in a short form
the page number to recall out in the internal memory and the actual valve of all eight variables usable on one page.
The data exchange format is equal in each mode.
4.6.3 Data format
The TA125 works in combination with the TI125 as Profibus- Slave. It posses 34 Byte
Data_Out and 4 Byte Data_In.

Next write data into Byte 1 up to 33 into Data_out. If you have less than 33 then fill up the
Data_out with zeros.
Next invert the trans_hs.new to indicate that the TA125 can read the data. If the slave has
received the data, it will indicate that by inverting the rec_hs.ack.
Receive
A new message has arrived, if rec_hs.new is unequal to trans_hs.ack. After reading the
data out of Data_in the master has to invert the trans_hs.ack to indicate that it is ready to
receive.
4.6.5 Compact mode
The software-Version 2.0.0 of the TA125/TI125 contains a new indicator mode as well as
the introduction of binary variable to the announcement in the TA125.
With this compact mode (PV- mode) it is possible to recall most efficient pages from the internal memory and set the variables of 1-8 to new values.
In this new indicator mode the profibus DP memory is divided as follows:
Output data
The output-area of the profibus DP covers 34 bytes. These are used for the selection of the
page which can be indicated and for filling variables with values. The variables are coded

4.7 Parameter input and configuration with MODBUS- interface
You can enter basic configuration of the TA125 by the internal configuration keys.
To enter the basic settings use the two keys on the rear side of the display PCB. We define
the key closer to the terminals as the left and the other as the right key.
Start the configuration menu by pressing both keys. Generally the left key will modify the
tag and the right key will confirm the setting and show the next tag.
The display shows:

Language =
Here you can select the user’s language. The text display is configured ex works and can
start immediately. The default parameters has an * in the table below:

The watchdog timer determinates a broken data wire. If
the TA125 gets no data in watchdog time, the TA125 will
show “ No connection to host !”. After receiving data
again the message disappears.
If “Yes” is entered all settings will be confirmed and the
configuration menu will be left. Otherwise the menu starts
from the beginning.
4.7.1 Display modes
From the software version 2.0 the TA125 has two different display modes. The general
mode the TA125 works according to ISO/IEC 6429. With this general mode all text functions of the TA125 can be used.
Additionally works the TA125 in compact mode. In the mode the TA125 gets in a short form
the page number to recall out in the internal memory and the actual valve of all eight variables usable on one page.
4.7.2 Data format
The TA125 in combination with TI125 works as MODBUS slave only. It has 100 HOLDING
Registers output range

4.7.4 Compact mode (PV- mode)
The software-Version 2.0.0 of the TA125/TI125 contains a new indicator mode as well as
the introduction of binary variable to the announcement in the TA125.
With this compact mode (PV- mode) it is possible to recall most efficient pages from the internal memory and set the variables of 1-8 to new values.
In this new indicator mode the modbus registers is divided as follows:
Registers in compact mode
The output-area covers 18 registers. These are used for the selection of the page which
can be indicated and for filling variables with values. The variables are coded according to
DIN 19245 part 2.

4.8.1 Format text (Function 8)
The function „SET GR. RENDITION“ sets format for the actual page respectively the following characters. Normally the text has 4 rows with 40 columns. After the Sequence „ESC [ 1
m“ the display has only one line with a figure height of 65 mm. The sequence „ESC [ 2 2 m“
toggles back to normal display.
It is possible to let flash some words to increase their recognition. The sequence „ESC [ 5
m“ enables flashing with 1 Hz; the sequence „ESC [ 6 m“ with 2 Hz. The sequence „ESC [
2 5 m“ stops flashing mode and shows the following characters normally.
4.8.2 Working with variables (function 11, 12)
The TA125 offers the ability to define fields in the text area as variables. Later the variables
can to be replaced by different contents, without uploading the whole page. The master has
to send only the variable number and content and the TA125 replaces the variable on the
defined place. This can be useful for process indications for instance.
The TA125 can manage 127 variables with a length of up to 10 characters. The sequence
„ESC [ 7 ; 9 V“ defines for instance a variable No. 7 with a length of 9 characters on the actual cursor position. This place will be reserved on the display immediately.
Later the variable get its contents with the sequence „ESC [ 7 v STX CONTENTS ETX“ as
often as the master will send this sequence.
4.8.3 Storing text pages (Function 13,14)
The TA125 stores up to 255 pages (max 32kByte) in its internal EPROM. The sequence
„ESC [ Pn t STX CONTENT ETX“ stores CONTENT in the page Pn.
This page can be recalled by the sequence „ESC [ Pn T“.
The pages are kept in memory even after power down. To erase the pages overwrite it with
a new content or use the hardware reset of the TA125, in this case all pages will be erased
4.8.4 Binary output (function 15)
The TA125 has a Open-Collector transistor out. This can be used for an acoustical actor for
instance. The sequence „ESC [ 1 X“ closes the transistor and the sequence „ESC [ 0 X“
opens it.
