Chapter 1 Safety precautions
Important information Read these operating instructions before starting the unit. They provide you with
important information on the use, safety and maintenance of the units. This helps
you to protect yourself and prevent damage to the unit.
Information intended to help you to avoid death, bodily harm or considerable
damage to property are highlighted by the warning triangle shown here; it is
imperative that this information be properly heeded.
The operating instructions are intended for trained professional electricians familiar
with the safety standards of electrical technology and industrial electronics.
Store these operating instructions in an appropriate place.
The manufacturer is not liable if the information in these operating instructions are
not complied with.
Safety Components inside the units are energized with electricity during operation.
For this reason, mounting and maintenance work may only be performed by
professionally-trained personnel while observing the corresponding safety
regulations.
The repair and replacement of components and modules may only be carried out
by the manufacturer for safety reasons and due to the required compliance with the
documented unit properties.
The units do not have a power switch. They are operative as soon as the operating
voltage is applied.
Intended use
The units are intended for use in industrial environments. They may only be
operated within the limit values stipulated by the technical data.
When configuring, installing, maintaining and testing the units, the safety and
accident-prevention regulations relevant to use in each individual case must be
complied with.
Trouble-free, safe operation of the units requires proper transport, storage,
installation, mounting and careful operation and maintenance of the units.
Mounting and installation The attachment options for the units were conceived in such a way as to ensure
safe, reliable mounting.
The user must ensure that the attachment hardware, the unit carrier and the
anchoring at the unit carrier are sufficient to securely support the unit under
the given surrounding conditions.
The units are to be mounted in such a way that they can be opened up while
mounted. Sufficient space for the cables must be available in the unit near the
cable infeed.
Sufficient space is to be kept clear around the units to ensure air circulation and to
prevent the build-up of heat resulting from use. The relevant information must be
heeded in the case of units ventilated by other means.
When the housing fasteners are opened, the front frame of the housing
hinges out upward or downward (depending on the unit version)
automatically.

6 BAL SX502 PAR EN 3.21
Battery replacement The units have a lithium battery used for data security of the real-time clock. The
battery can explode if replaced improperly.
Grounding All devices are equipped with a metal housing. They comply with safety class I and
require a protective earth connection. The connecting cable for the operating
voltage must contain a protective earth wire of a sufficient cross section (DIN VDE
0106 part 1, DIN VDE 0411 part 1).
EMV-Massnahmen The devices comply with the EU Directive 89/336/EEC (EMC Directive) and provide
the required interference immunity. Observe the following when connecting the
operating voltage and data cables:
Use shielded data cables.
The data and operating voltage cables must be laid separately. They may not
be laid together with heavy-current cables or other interference-producing
cables.
The cable thickness must be properly assessed (DIN VDE 0100 Part 540).
The cable lengths inside the units are to be kept as short as possible to prevent
interference. This applies especially to unshielded operating voltage cables.
Shielded cables are also to be kept short due to any interference which might
be emitted by the shielding.
Neither excessively long cables nor cable loops may be placed inside the units.
The connection of the cable shielding to the functional ground (PE) must be as
short and low-impedance as possible. It should be made directly to the
mounting plate over a large area with a conductive clip:
control
conductive clamp
mouting plate
data line terminals
bare
metal surface
The cable shielding is to be connected at both cable ends. If equipotential
bonding currents are expected due to the cable arrangement, electrical
isolation is to be performed on one side. In this case, capacitive connection
(approx. 0.1μF/600 V AC) of the shielding on the isolated side must occur.
Disposal Units or unit parts which are no longer needed are to be disposed of in accordance
with the regulations in effect in your country.

Chapter 3 Character display
LED-matrix The characters are displayed on an LED matrix. A matrix module is 16 LED dots
(pixels) high and, depending on the unit version, the following number of pixels
wide:
Unit versions SX502-x20/xx/xx-xxx/xx-xx: 120 pixels
Unit versions SX502-x40/xx/xx-xxx/xx-xx: 240 pixels
Character display The units feature several different character sets, which will be elaborated on later.
The following explanation is based on the Acala 7 character set.
With this character set, the character width is five pixels and the space between
characters is one pixel. Units with a 120 pixel-wide matrix can therefore display 20
characters on a line and units with a 240 pixel-wide matrix can display 40
characters on a line.
The character height is seven pixels. Thus two lines of seven pixel-high characters
with a space between lines of two pixels can be displayed on a 16 pixel-high matrix
module.
This means that two lines of 20 characters each can be displayed on a 120 x 16
pixel matrix and two lines of 40 characters each can be displayed on a 240 x 16
pixel matrix.
If the entire height of the matrix is used, characters with twice the character height,
i.e. 14 pixels, can be displayed. The Acala 14 condensed character set, for
example, is available for this. It uses a height of 14 pixels out of the 16 pixels
available in the matrix.
With this character set, the character width is eight pixels and the space between
characters are two pixels. Ten pixels are thus required for the width of each
character. According to this, units with a 120 pixel-wide matrix can therefore display
one line with 12 characters and units with a 240 pixel-wide matrix can display one
line with 24 characters.
Character sets The following pictured character sets are available. They differ in character height
(seven, 14 or 16 pixels) and in character width (normal, extended or condensed).
The number of characters (number of lines x number of characters per line) which
can be displayed on a 120 x 16 and 240 x 16 pixel matrix for each character set is
noted in the table.

The character sets marked with * in the table are permanently installed in the units.
The remaining character sets are delivered on data carriers.
The data carrier also contains the PC tool 'DisplayManager' for installing the
character sets. In addition to that, the tool is used for creating user-defined
character sets, for saving character sets on data carriers and for restoring the
installed character sets.
Multi-line units To display texts containing more characters than can be displayed with a 120 x 16
or 240 x 16 pixel matrix, we offer unit versions with a suitable number of matrix
modules arranged vertically.
The following figure shows unit version SX502-420/05/xx-xxx/xx-xx with two
vertically arranged 120 x 16 pixel matrix modules as an example. Character set
Acala 7 allows 4 x 20 characters to be displayed, and 2 x 12 characters can be
displayed with the character set Acala 14 condensed.

12 BAL SX502 PAR EN 3.21
The physical distance between the matrix modules corresponds to a height of two
pixels. Thus the distance between the first and second lines is the same as
between the second and third lines.
The SX502 series also includes units with three or four vertically arranged matrix
modules. They can display six or eight lines with the Acala 7 character set and
three or four lines with the Acala 14 condensed character set.
Character height The actual character height depends on the height of a character in pixels and the
size of the pixel diameter and spacing.
The SX502-xxx/03/xx-xxx/xx-xx unit versions have a pixel diameter of approx. 3
mm and a pixel spacing of approx. 4.7 mm.
The SX502-xxx/05/xx-xxx/xx-xx unit versions have a pixel diameter of approx. 5
mm and a pixel spacing of approx. 7.6 mm.
This results in the following actual character heights for the character sets,
depending on the unit version:

Proportional lettering The previously described character sets display the characters in non-proportional
lettering. The same number of pixels is available for the width of each character.
The character sets Acala 7 P and Acala 14 P, which are included in delivery on
data carrier, display the characters in proportional lettering. Each character uses
the width it requires visually.
LED color The device models SX502-xxx/xx/xR-xxx/xx-xx have a display with red fluorescent
color. The fluorescent color cannot be changed.
The display of the device models SX502-xxx/xx/xM-xxx/xx-xx have a fluorescent
color which can be switched between red, green and orange.

In menu item 51 the setting  has to be chosen.
Dynamic text call A text appears in the display if its text number is present at the data inputs of the
parallel interface and a rising pulse edge [4 ... 6] arrives at input K15. Text number
and impulse must be at a minimum of 10 ms simultaneously and stably at the data
inputs.
In menu item 51 the setting  has to be chosen.
Function inputs F2 and F1 must have an L signal.
Coding of text numbers The text numbers can be binary, BCD or 1-out-n coded. The coding must be set in
menu item 50.
With binary coding [1, 4] the text numbers 0 ... 9999 are possible.
With BCD coding [2, 5] the text numbers 0 ... 9999 (static text call) or 0 ... 7999
(dynamic text call) are possible. Invalid text numbers (not BCD coded) lead to an
undefined display.
With 1-out-of-n coding [3, 6] the following text numbers are possible:
Static text call 0 ... 15 (data inputs K15 ... K0)
Dynamic text call 0 ... 14 (data inputs K14 ... K0)
The lowest data input with H signal has priority. With an L signal at the data inputs
K15 (K14) ... K0, the display is cleared and an LED dot flashes in the upper left
corner. If, instead, a start text should appear in the display (e.g. 'System trouble-
free'), this must be stored in the text memory with the text number 0 and the display
of the start text must be set in menu item 20.
Insert variables In menu item 51 the setting  has to be chosen.

BAL SX502 PAR EN 3.21 15
Texts into which variables are to be inserted are given placeholders for the
variables (up to 256). After the text call [1 ... 6] the placeholders are dark.
The variables appear in the display when they are encoded in binary form at the
data inputs K7 ... K0 of the parallel interface and an increasing pulse edge arrives
at input K15 (H signal at function input F2, L signal at function input F1) [7]. The
insertion position is then automatically increased by 1. Variables and impulse must
be at a minimum of min. 10 ms simultaneously and stably at the data inputs.
The variables are inserted from left to right and start at the first placeholder. It takes
place from another placeholder if its position is binary coded at the data inputs K7
... K0 of the parallel interface and at the input K15 an increasing pulse edge arrives
(L-signal at the function input F2, H-signal at the function input F1) [8]. Insert
position and impulse must be at a minimum of 10 ms simultaneously and stably at
the data inputs.
The variables are deleted and the current insertion position is reset if an H signal is
applied to function inputs F2 and F1 and a rising pulse edge arrives at input K15 [9].
Brightness reduction The brightness can also be reduced with a H signal level on function input F1.
Flashing Flashing of the display can also be activated with a high signal level at function
input F2.
Initial text Once the operating voltage has been applied, an LED dot in the upper left-hand
corner of the display illuminates to indicate that the unit is ready for operation. If an
initial text is to appear in the display instead (e.g. 'System operational'), this text is
to be saved in the text memory with text number 0, and displaying of the initial text
is to be set in menu item 20.
Paging If a text contains more characters than can be shown in the display, it is
automatically displayed in paging mode. The page change interval can be set
between 3 and 30 seconds in menu item 21.

Chapter 5 Parameterization
Menu display The parameterization of the devices is carried out in a menu of the menu display. In
normal operation, the status messages appear in the menu display.
Menu operation To start the menu, press both menu buttons simultaneously (approx. 1 sec.) until
the first signal appears in the menu display. Now, you can navigate in the menu as
follows:
Next menu item: Shortly press key []
Page menu items forward: Press key [] long
Previous menu item: Double click on key []
Page menu items backward: Double click on [] and keep it pressed
Next setting Shortly press key []
Page settings forward: Press key [] long
Previous setting Double click on key []
Page setting backward: Double click on [] and keep it pressed
The menu ends in menu item 99 with the button []. The settings made are either
saved (set), not saved (escape) or the factory settings, except for menu item 01,
are reset, depending on the setting selected in menu item 99.
Cancelling the menu without saving the settings made is possible by pressing both
menu buttons longer (approx. 1 sec.) or will occur automatically if 60 seconds pass
without a menu button being pressed.
Once the menu is closed, the unit behaves in the same manner as when the
operating voltage was applied.
An LED dot illuminates in the upper left-hand corner of the display in menu mode.
Control of the display is not possible in menu mode.
Menu table The menu items are displayed in the following menu table. The factory settings are
marked with an *. Individual menu items or settings can be suppressed in another
menu item, depending on the unit version or setting.

Initial text Once the operating voltage has been applied, an LED dot in the upper left-hand
corner of the display illuminates to indicate that the unit is ready for operation. If an
initial text is to appear in the display instead (e.g. 'System operational'), this text is
to be stored in the text memory with text number 0, and displaying of the initial text
is to be set in menu item 20.
If a display test is preselected in menu item 24, it appears in the display before the
initial text.
Paging interval If a text contains more characters than can be shown in the display, it is
automatically displayed in paging mode. The page change interval can be set
between 3 and 30 seconds in menu item 21.
Character set In menu item 22, you can set the default character set used to display the texts.
Character sets Acala 7, Acala 7 extended, Acala 14 condensed and Acala 14
extended are permanently installed in the units.
A user-defined character set with a character height of seven pixels can be called
up with the  setting. The Acala 7 P character set is preinstalled here. It can be
replaced by a user-defined character set with up to 7 pixels character height.
A user-defined character set with a character height of 14 pixels can be called up
with the  setting. It can be replaced by a user-defined character set or an
optional character set (Acala 14 P, Acala 16 condensed, Acala 16 or Acala 16
extended).
The optional character sets and the PC tool 'DisplayManager' a tool for generating
user-defined character sets are included in delivery on a data carrier. The tool is
also used to install character sets, to save character sets on data carriers and to
read back installed character sets.
Language In menu item 23, you can set the language in which the weekday is displayed
(abbreviated to two letters).
Display test In menu item 24, you can set whether a display test is to be performed after the
operating voltage is applied.
Coding of the text numbers The text numbers can be coded binary, BCD or 1-out-of-n. The coding is set in
menu item 50.
Text call In menu item 51 you can set whether the text is called up static or dynamic.
Time/date The year, month, and day of the real-time clock are set in menu items
90 –92. The time at which the clock is to be started is set in menu items 94 –95.
Then select menu item 99 and select the setting  there. When the set time is
reached, briefly press the left menu button [↕], now the clock is now set to the
current time.
If the settings in menu items 90 –92 (date) and 94 –95 (time) are not changed
when the menu is run through, the current settings are retained when the menu is
exited. Therefore, the clock only needs to be set when running through the menu if
this is intended.
Time and date can be set independently.
Attention: Setting unrealistic date values, e.g. 31/02/09 can lead to unpredictable
date displays and is therefore impermissible.
