Commissioning and installation
You must be familiar with the commissioning procedures and the functions of the programmable controller system being used. For detailed
information, please refer to the manuals of the PLC system.
Commissioning of the LCA 300/320/325
1. Switch off the equipment or machine
2. Connect the operating voltage to the LCA 300/320/325. The operating
voltage connections 1 (0V) and 2 (+24V) are 2-pole terminals accepting
wires up to 2 mm2. The current consumption and the operating voltage
limits are indicated in the section Specifications.
3. Load the project created by means of the configuration software
LCAPRO (supplied by Systeme Lauer) into the LCA 300/320/325
4. Switch on the equipment or machine

Attention!
The protective conductor and 0V of the operating voltage are separated
in the device. The protective conductor is connected to the enclosure of
the interface connectors. The enclosure must be grounded to avoid noise
in the best way. The grounding wire (4 mm2) must be as short as possible.
Additionally, 0V must be neutralized near the power supply (according
to VDE regulations).

Tip!
Creation of a project requires use of the LCAPRO software. Other software
packages are not admissible and may cause malfunctions in the LCA
and the PLC.
Use only the drivers specified for the PLC. Other drivers may cause
malfunctions in the LCA and the PLC.
Malfunctioning of the LCA and the PLC may occur, if the LCA and the
PLC are not configured correctly. Check the correct function/reaction of
the LCA.

1.3 General measures for inter
ference suppression
interference
Secure functioning can only be guaranteed up to a certain noise level,
even if the best electronic design and components are used. To avoid
unnecessary failure of devices, the following notes should already be
observed when planning the application:
1. If possible, run power supply and signal lines of LCA devices in separate cable conduits
2. Allow a safety clearance to interference sources of 250 mm or more
3. Inductors installed in the same control cabinet (contactor and relay
coils) must be wired to corresponding recovery diodes or RC surge
absorbing components
4. Do not use fluorescent lamps to illuminate the control cabinet
5. Determine a central grounding point with a large cross section to
connect the protective earth conductor (PE)
6. If high magnetic field intensities are present (generated for example
by large transformers), we recommend installation of a separating
sheet metal
7. Suppress interference in frequency converters and other devices by
shielded filter circuits
8. Shielded signal lines provide the best means to eliminate highfrequency noise. The shield should be grounded at both ends.
However, an equipotential bonding conductor 10 mm2 must be
installed (see VDE 0100, Teil 547).
9. If high noise levels are present, install factory-assembled filter circuits
in front of the power supply to suppress noise in an efficient way.

1-6

Commissioning and installation

1.4 Installation notes
A fault-free operation of the text display requires a distance of 250 mm
or more between all sources generating radiated noise and the LCA
300/320/325. This applies also to the data lines and power supply lines
of the LCA 300/320/325.
If the cable length exceeds 5 m, we recommend shielded cables (grounded at both ends). Please note that this may require an equipotential
bonding conductor with a cross section of at least 10 times that of the
cable shield (due to equalizing currents).
Cables to the LCA 300/320/325 should be separated from high voltage
cables and high-frequency cables.

1.5 Power Supply V
oltage
Voltage
A fault-free operation of the text display LCA 300/320/325 requires observance of the following notes:
Operate the LCA 300/320/325 only within the indicated operating
voltage range
Short-term supply voltage dropouts of up to 20 ms are admissible
LCA devices may only be operated with the safety extra-low voltage
according to VDE 100 (functional extra-low voltage with protective
separation). The control-power transformer must meet VDE 0551
regulations. In this case, a single-pole grounding of the operating
voltage according to VDE is admissible. This grounding method is
recommended for the operation of our devices.
Without single-pole grounding of the operating voltage, you have
to install your own control-power transformer in order to operate
the LCA 300/320/325
If contactors or relays are actuated by the operating/signal voltage,
these devices must be connected to recovery diodes and/or protective
circuits for interference suppression

Communication between the LCA and the PLC

2.1 Communication principle
The electrical connection between a PLC of any type and the LCA 300/
320/325 is effected by a special adapter cable (order number LCA 7xx).
Communication is based on a principle which can easily be understood.
The transmission scheme is described below:
If a new call on operation text, byte 0 is written into the PLC
Byte 1 is written into the PLC
If any key has been pressed, byte 3 is written into the PLC
If any preset value has been edited, the corresponding byte(s) is (are)
written into the PLC
The next coherent block is read from the PLC
Repetition, beginning with step 1
Bytes B 00...B 09 are permanently assigned in the LCA 300/320/325
(see the section Data area structure). Bytes B 10...B 255 are available
for any operating projects.

Communication between the LCA and the PLC
Tip!
Creation of a data record requires use of the LCAPRO configuration
software. Other software packages are not admissible and may cause
malfunctions in the LCA and the PLC.
The functionality of the LCA 300/320/325 depends on the configuration
software LCAPRO. This software enables creation of a data record which
contains texts, variable definitions and other elements. This data record
is transferred via a serial interface (RS 232) into the LCA 300/320/325
using the specific firmware for the PLC interfacing. The data are then
stored in a non-volatile memory of the LCA 300/320/325.
Use only the firmware specified for the PLC. Another firmware may cause
malfunctions in the LCA and the PLC.

2-2

Communication between the LCA and the PLC

2.2 System area
Due to its functionality, the LCA 300/320/325 enables a maximum of:
1024 message texts (information and failure messages)
256 idle texts
256 operating texts
Help text for each message text, idle text and operating text
Each idle text, message text and help text may contain up to 32 lines,
with 40 characters each. Operating texts are assigned a length of 2 lines
x 40 characters. Each text group is assigned a certain priority. Operation
texts have the highest and the idle text has the lowest priority.
Each message text is assigned a message bit in the PLC. The 1024 messages (message 0...1023) are stored in the area from byte B 10.0 to byte
B 137.7.
If the message bit is set to logical 1, the message text is displayed. If it is
set to logical 0, the message text is cleared. If several message bits are
simultaneously set to logical 1, this status is registered in the message
buffer of the LCA 300/320/325. A maximum of 128 information and
128 failure messages can be stored in the message buffer which is,
however, volatile. If the message buffer is full and if messages are
selectively deleted or new messages activated, a correct timing cannot
be guaranteed. According to the selected message format, messages
are displayed as first or last message or cyclically.
An idle text is only displayed on the LCA 300/320/325, if no message or
operating text is activated.
Conversion formula:
Even byte address a
Address a.b -> Message text
Example: Address 34.2 -> Message 202
Odd byte address a
Address a.b -> Message text
Example: Address 35.2 -> Message 194

The LCA 300/320/325 displays the highest (enabled) priority.
The help priority for each base priority can be activated by the internal
function of the 7th key (HELP), as long as this key is pressed.
The failure priority can be displayed, if a message bit is set to which a
message text of the failure priority has been assigned. Failures are
only displayed after reset of bit 7.7. To suppress failure displays, bit 7.7
must be set to logical 1.
The information priority can be displayed, if a message bit is set to which
a message text of the information priority has been assigned. Information are only displayed after reset of bit 7.6. To suppress information
displays, bit 7.6 must be set to logical 1.
The operating priority can be selected, if bit 7.3 is set to logical 0. To
suppress operating priority selections, bit 7.3 must be set to logical 1.
The idle priority is displayed, if no information texts, failures texts, operating texts or help texts are active.

Communication between the LCA and the PLC

2.3 Variable formats
Character and numeric variables with different formats are used in the
LCA 300/320/325.
When using character variables, a string is assigned to the logical states
of individual (BIT variable) or several (STRING variable) bits.
When using numeric variables, the system differentiates between BINARY
and BCD coded values transferred by the PLC. The LCA 300/320/325
converts the numeric variable and displays it in a decimal format.
Variables can be allocated to all addresses (0...255). The user has to take
care that variable and function/message bit areas do not overlap.
All variables can be used as actual and preset variables. If the operating
priority is enabled, the editor function enables a preset variable to be
changed and to be transferred into the PLC.
The message bit area is automatically limited to the range from byte 10
to the most significant byte used by an allocated message text.

Tip!
If for example M186 (byte 32.2) is used as maximum message text, the
addresses beginning with byte 34 can be used for variables.

2.5 The Printer

The LCA 325 features a printer interface and supports one printer
protocol. Printer parameters are selected via the LCAPRO configuration
software (version 4.0 and higher).
Printer parameters

In the LCAPRO configuration software, define printer parameters under
the PROJECT PRINTER PARAMETER menu item.
The following parameters can be set:
Handshake selection: NONE, XON/XOFF, RTS-CTS. With NONE
handshake, printer characters are send without any verification. The
printer always signals operational readiness. With XON/XOFF
handshake, printing is interrupted only if XOFF is received. With RTSCTS, data is send only if RTS is set to logical 1.
Printer output direction UP or DOWN. Corresponding to the physical
design of the printer it is possible to select whether the first or last
line is transmitted first to the printer. For the LCA printer it is favorable
to transmit the last line first. Therefore, select UP.
The printer baud rate is selectable between 1200 and 9600 baud
The number of printer data bits is selectable between 7 or 8 data bits
The number of printer stop bits is selectable between 1 or 2 data bits
For printer parity, NONE, EVEN or ODD parity can be selected
In addition, the following function can be set via the LCAPRO
configuration software:
Printer initialization. After powering-up, 0 up to 8 characters are send
to the printer. The default setting is OD 0A - carriage return linefeed.
Replacement characters for freely definable display characters. For
LCA display up to eight characters can be defined. These characters
can not be printed. Thus eight replacement characters have to be
defined.

2-20

Communication between the LCA and the PLC

Printer status

In the PLC, the status of the printer is reported in byte 2, bit 2. The
operational readiness is only. The operational readiness is only
unambiguous with RTS-CTS handshaking. The printer always signals its
readiness if NONE handshake has been selected.
The communication loss to the PLC aborts the printing process.

Hard copy

A hard copy of the current display contents can be initiated from the
PLC. For this, a 0 -> 1 transition of bit 0 of byte 8 is evaluated. The
contents of the display is output for printing line-by-line if this transition
is detected. Bit 0 of byte 2 is set if printing has ended. This bit remains
set until the request bit 0 of byte 2 is reset to 0. The hard copy print-out
is aborted if a time-out condition is detected.
If a hardcopy request is received during message printing then this request
is only processed after finishing the message printout.

Message printout

A printout of all defined message can be initiated by the PLC. If bit 1 of
byte 8 is set to 1 then the message area is checked for 0 -> 1 transitions.
The respective message is inserted into a print queue if one or several
transitions are detected. Active printing is signaled via a set bit 1 of byte
2. All queued messages are cleared from the queue if bit 1 of byte 8 is
set 0. All message lines are printed. Printing and retrieving the variables
from the PLC is performed line-orientated, i. e. variables are entered
into the line if the corresponding line is printed.

Selection of the next operating text

"CURSOR

ê"

Selection of the previous operating text

"EDIT"

Exit the operating text selection

Select the desired operating text by pressing the ENTER key.
The flashing display cursor is now positioned on the left digit of the
first variable which can be edited (preset variable).
Select the variable to be edited by pressing one of the following keys
"CURSOR ç è"
Increment or decrement the variable by pressing one of the following
keys "CURSOR é ê"
Transmit the modified variable into the PLC by pressing the ENTER
key. After the transfer has been success-fully completed, the cursor is
positioned on the next variable which can be edited (preset variable).
Press ENTER on the last variable to exit the editing mode
If you do not want to change a variable nor transfer the modified
value into the PLC, select another variable using "CURSOR ç è" or
exit the menu by pressing the EDIT key.
Return to the operating text selection by pressing the EDIT key
Select another operating page or exit the operating priority using
the EDIT key

Tip!
LCAPRO enables specification of a period after which the operating
priority is automatically deactivated, if no key has been pressed.

cloth.
This is especially important when using the LCA 300/320/325 in an Ex
area.

Attenion!
The LCD display contains poisonous substances. Do not touch the display,
if it is damaged.

Attenion!
The designated product is only intended for being installed in other
machines. Commissioning is prohibited, until conformity of the final
product with the regulation 89/392/EWG has been ascertained.

3.2 Using the LCA in an Ex area

Attenion!
Static charge of the front panel is possible. Clean only with a moist
cloth.

The LCA 300/320/325 can be pre-setup for use in an Ex area. This must
be known when ordering the device. A subsequent release or certified
declaration by the manufacturer is not possible. The devices can be presetup for use in Ex area 1 or 2.
An overpressure encapsulation with a low-pressure system is available.
This means that a difference in atmospheric pressure of 2-4mbar exists
between the interior space and the outside of the front. With higher
pressures, unwanted cambers may occur above the keys.
The devices are only pre-setup for use in Ex area 1 or 2. This means that
the devices must be installed according to VDE 0165 or VDE 170/171,
depending on the application. For installation of the devices in
encapsulated enclosures with pressure protection - including test
certifications which may be required - Systeme Lauer informs the user
about the cooperating companies on request.
For use of the devices in Ex area 2, please refer to the specifications of
the manufacturer and an explanatory memorandum published by Systeme Lauer. The specifications of the manufacturer may be used as
basic documentation for the certification of the device in Ex area 2.

Specifications of the manufacturer concerning Ex area 2
Safety class of the text displays, operator consoles
and visual display devices

We design, develop, manufacture and test our devices according to the following VDE-EN regulations:
a)
b)
c)
d)
e)

DIN VDE 0160/12.90 considering the following sections:
EN 60204 T.1/DIN VDE 0113 T.1/02.86
DIN VDE 0110 Part 1/2/01.89
EN 60950/DIN VDE 0805/05-90
DIN IEC 68 Part 2-3/Part 2-6

According to our knowledge, based on the information given by the German physical technical federal institution and the
German VDE test agency, the majority of our devices can be used in the Ex area 2. According to circumstances, the specific
characteristics of each individual device must, however, be looked up in the declaration given by the manufacturer. The Ex
area 2 mentioned above refers to areas in which one has to expect that a dangerous, explosive atmosphere occurs only
rarely and, if it occurs, only for a short time.
An explosive atmosphere is defined as a mixture of inflammable gases, vapour, mist or dust in which a reaction propagates
itself after ignition. Equipment which does not generate sparks, arcs, or inadmissible temperatures during normal operation,
is admissible in theses areas. Normal operation is defined as the undisturbed operation of equipment within the specified
limits, for example the temperature limits. Each equipment must feature a good technical industrial quality which we can
guarantee.
According to the requirements specified by the German physical technical federal institution and the German VDE test
agency, prototype test certifications for an equipment to be used in area 2 are not required. For installation, the VDE 0165
regulations must be observed.
Apart from the manufacturers specifications referring to a specific device, special requirements exist whichmust be observed
for all devices manufactured by our company:
1.

The supply cables for the operating voltage may only be connected or disconnected to the PCS operator
console after switching off the power.

Interface connectors may only be connected or disconnected after switching off the power.

EPROM cassettes may only be installed or removed after switching off power to the devices.

Before using devices in Ex area 1, an inspection and acceptance of the system by the physical technical federal institution
in Brunswick or Berlin is required in any case, according to the German regulation.
