Question

What happens when multiple Sensors are used and they interfere with each other? What can be done to resolve the problem?

Answer



Mutual interference:

An error occurs in the analog value to the Analog Input Unit of the Digital Panel Indicators or Programmable Controllers.

(For example when the input is 10 mA, an input of 4 mA is indicated.)

When this happens, the error indicator (red LED) will begin to flash.

Countermeasure:

Place the Sensors apart from one another so that they do not interfere with each other.
