TEXT DISPLAY

LCA 042

The attractively designed LCA 042, incor-

porates many interesting features. One

of the successful LCA series of text dis-

plays.

Text displays are not exotic addons, but tools, with

which you can considerably improve the service

quality of machines and systems. Text displays

■avoid malfunctions,

■indicate how faults can be eliminated,

■provide operator guidance,

■give important set-up information,

■show what the machine is currently doing,

■support maintenance and servicing,

■issue instructions for carrying out adjustments,

■combine variable values with fixed texts

LCA text displays save time and money. Neither

designers nor production personnel can do without

textdisplays.Thereforetheyarepartofthestandard

equipment of every machine.

With the LCA 042 text display you can invoke up to

200messages.Itcanbedrivenbyanyprogrammable

con-troller or by individual contacts or proximity

switches.

1.1 CONNECTION OF THE PROG. CONT.

The parallel interface is the most important connection

be-tween the machine (controller) and the text display

LCA 042. All significant functions of the LCA 042 are

performed via this interface. These functions are:

- invoking the message texts (max. 200)

- invoking the message variants (functions)

- entering external variables

All inputs are high-active (Ri = 2.6kΩ)

BIN 0... 199

BCD 0... 199 = coded message number

CLOCK = 1. invoke additional messages

2.display external variables on text display

3. invoke further messages

(at first message)

TEXT/VARIABLE = switch between message text and

external variable

DIRECT/SEQUENTIAL = switch between direct message and first

message (sequential display)

The connection to the programmable controller is made

via industrial adapter LCA 020 or round cable LCA 038.

Text display LCA 042 distinguishes between PROGRAM-

MINGand OPERATION.During programmingoperation of

the LCA 042 is not possible.

Before the LCA 042 is put into operation the following

preparations must be made:

1. initialize

2. store message texts

3. determine positions of variables by means of place

holders

-PROG. CONT. CONNECTION VIA INDUSTRIAL ADAPTER

1.1.1 INDUSTRIAL ADAPTER LCA 020

When using control cabinet techniques, connections are

normally made by means of screw terminals. To enable

theuseofthistypeofinstallationwiththetextdisplayLCA

042 we supply the industrial adapter LCA 020.

Theelectricalconnectionsbetweentheprogrammable

controller and the LCA 020 are made using the well-tried

wiring method via terminals and the connections

between the LCA 020 and the text display LCA 042 are by

means of ready-made flat cables (LCA 030 or LCA 031).

ready-made round cables.

We supply round cable LCA 038 in 4 standard lengths

(from 200 to 800 cm) and a suitable plug for the text

display.

Further details can be found in the description of the

round cable.

two units are connected together, no messages can be

invoked.
