Does anyone know when a sensor is using a Dual voltage Supply (+/- 15VDC) for it's source power, do both +15V and -15V supply to the sensor require fusing or, can a single Fuse be placed in series with the common line?
What about the signal line itself? OK to just fuse the signal line and not the source Line(s)?
What is the recommended practice. I typically come across some installations with out fusing on either of the lines going to a sensor. Most, have worked for years, but that is not to say I condone the practice.
Thx.
