- if everything mentioned above fails, try to update the sensor's FW
- if the update fails too, take a multimeter and measure the sensor's power
consumption and the voltage readings on the orange and white wires of
the sensor, make a short video of that check and send it to us;
To check the power consumption of the sensor, select the A
your multimeter/multitester. One of the probes of the multimeter must be
connected to the COM socket and the other – to the mA socket.
Then the sensor's black wire must be connected to the GND of the power
supply. One probe of the multimeter has to be connected to the red wire of the
sensor and the other one to the PWR wire of the power supply.
Compare the reading you get with the normal values indicated in the table
below. Take a photo or record a short video of the check.
To check if the line A and line B of the sensor are intact, connect one of the
multimeter's probe (the one plugged into the multimeter's COM socket)
between the black wire of the sensor and the GNR of the power supply. The
other probe (the one plugged into the multimeter's V
