Sensor Voltage Too Low

What does E3-16175 mean?

The sensor voltage detected on the I/O bus module is below the acceptable threshold. This indicates a potential issue with the power supply to the connected sensors or a fault within the sensors themselves, leading to inaccurate readings or complete sensor malfunction and unreliable process control.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Inspect the sensors for damage or proper operation; replace any faulty sensors.

2. 4

   Measure the voltage directly at the sensor input terminals on the I/O module.
