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 is highlighted by the warning triangle shown here;...
EMC measures The devices comply with the current EU Directive (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.
Unit description Model designation This manual applies to units with the following model designation (x = the 'x's in the model designation indicate the size and design of the units: SX502-xxx/xx/xx-xxx/xx-S0 Unit construction The following figure shows model type SX502-220/05/xx-xxx/xx-xx as example for the other model types.

Function inputs The function inputs are located on the screw-type terminal strip of the control computer. They allow reduction in brightness and flashing of the display, independently of commands via the serial interface (see Chapter xxx). The function inputs are designed for the following signal voltages: Signal voltage: L = -3.5...+5 V (open input = L) H = +18...30 V (active H), M = reference potential...
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 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.
Interface Control The units are controlled via the serial interface. It has the formats RS485 and RS232. The interface format is set in menu item 01. Preferably, the interface RS485 is to be used for activation. It is galvanically isolated from all other electric circuits and provides the best preconditions for a reliable and safe operation of the devices due to its physical characteristics.

The shielding is connected on both line ends For the signal ground (GND) use a wire pair short-circuited on both ends in the data cable. The shielding may not be used as the signal ground. A twisted pair of conductors is used each for Tx+ and Tx- and for Rx+ and Rx-. Non-observance of this instruction causes the protective function of the twisted-pair cable to be lost.
Control Text types The devices can display dynamic and static texts. Dynamic texts can be changed while the unit is running. They are generated from within the process and sent to the display as data telegram. Static texts cannot be changed while the unit is running. They are compiled using the PC tool 'Text Manager' included on data carrier and loaded in the text memory via the serial interface.

In principle, updating could occur with dynamic texts containing both the fixed and the variable text components. However, the data transfer required here is considerable. The SX502 series offers the advantageous alternative of a one-time transmission of the fixed text components to the display and subsequent insertion of just the appropriate characters (variables) to update the variable text components.
Flashing of the entire display can also be activated with an H-signal at function input F2 (priority over commands). Marquee text Marquee text display is activated from the current position in the text with the $Y command [9]. It remains active up to the end of the text or a forced line break ($C). If a seven pixel-high font is currently selected, e.g.
Brightness The brightness of the display can be reduced with the $B1 command [36] and reset to normal brightness with the command $B0 [35]. The brightness of the display can also be reduced with an H-signal on function input F1 (priority over commands).
Individual line selection Application The activation of the devices as described in chapter "Control" is optimized for applications in which individual texts are shown in the display. Longer texts are written in several lines of the display due to the automatic line break. When the text contains more characters than can be displayed, it will be automatically displayed in paging mode.
For the other device functions, the commands described in Chapter 7 shall apply. Display dynamic text To display a dynamic text, its characters (cc…) are transmitted to the selected line as a data telegram [42]. Any text in the display is deleted when a new text is called up. Display static text A static text in the selected line can be loaded using the $Lxx$Tn...

Parameterization Menu The parameterization of the devices is carried out in a menu in the menu display. In normal operation, status messages appear in the menu display. Menu operation To start the menu, press both menu buttons simultaneously (approx. 1 sec.) until the first menu item appears in the menu display.
