Display Illumination - Gira 5142 00 Product Documentation

4.2.4.5.6 Display illumination

The display of the device has white backlighting. The function of the backlighting is specified in
the "Function of the LCD illumination" parameter in the "Display" parameter node in the ETS.
- For orientation, the LCD illumination can be switched permanently on or off.
- The LCD illumination can be switched using a separates 1-bit communication object (the
telegram polarity can be configured). It is also possible here to control flashing with a
frequency of approx. 2 Hz via the object.
- The background illumination can be switched on by pressing any desired button and
switched off again automatically after a delay time has elapsed. Here the parameter "Time
for automatic switch-off" in the parameter node "Display" defines the length of the delay
until switch-off after the last button-press. Each button-press re-initiates the delay time.
- The backlighting can flash together with all status LEDs with a frequency of about 2 Hz,
when the communication object for the alarm message display is active.
i The display of an alarm has a higher priority than the parameterisation of the LCD
illumination in the ETS.
i The brightness of the LCD illumination and all status-LEDs can be defined in the ETS on
the "General" parameter page. Optionally the brightness can be changed during operation
of the push button sensor, controlled by a 1-bit communication object.
