LED displays
LED CAN Bus
Status of inputs and outputs
Outputs:
- 0..100% green, the luminosity of the LED changes depending on the output signal,
100% = full luminosity
- In manual mode, the output LEDs additionally flash yellow
Inputs:
- Sensor value valid: LED lights up green:
- Sensor value outside the measuring range: LED lights up red
- No sensor (sensor type) configured: LED off
- Negative voltage at the input falsifies the measuring signal: all input LEDs light up red.
The affected input flashes red.
- The +10 V DC auxiliary voltage breaks down. Caused by incorrect wiring:
LEDs of the 0/2..10 V DC inputs lights up red.
