The LED matrix of these large size displays is realized in cluster technology. It has a character height of 350 or 700 mm and allows reading distances up to 140 or 280 m. The large size displays consist of single modules that can be strung together horizontally or vertically.
With character heights of 350 or 700 mm the housings are correspondingly large. However, to guarantee safe handling during installation and commissioning, the large size displays of the SX702 series consist of individual display modules. The modules can be lined vertically or horizontally so that the line length and number of lines can be defined individually.
The display modules are designed for wall mounting or they are mounted on carrier systems. The designing of the systems takes place in cooperation with the customer.
The large size displays are off ered either with a one- or a double-sided display. The versions with a double-sided display have a LED matrix on the front and on the rear side and show the same information on both sides.
After opening the housing the menu display is visible inside the device. Operation modes, parameters and device functions are defi ned without the need of the main display to be visible – an operational convenience especially with large volume devices or at exposed installation sites.
The devices are equipped with PLC-compatible function inputs. They allow the activation of device functions such as fl ashing, blanking and reduction of the LED brightness (day/night mode) independent from the signals over the data interface.
The large size displays support the interfaces for the industrial communication: field buses, network topologies, serial control, etc.
Fixed texts are defi ned with an address in the internal text memory. Upon receipt of an address the corresponding text appears in the display. This operating mode is advantageous if recurring texts are displayed. Variable information such as current measured values, quantities or time and date can be displayed in the texts. A fixed text can also be used as initial text at power-on, e.g. ”System trouble-free“.
In terms of control and device functions the SX702 series corresponds to the SX602 series.
