Frequently Asked Questions about KV-16EYR

What are the wiring precautions that should be taken for these Keyence expansion units?
Some wiring precautions that should be taken to stay safe, is to make sure that the power is turned off completely before starting any wiring to the units. Also make sure that the temperature and humidity is suitable for these units and that there will not be any drastic changes in temperature or humidity. To keep the internal circuits from over heating and becoming damaged, do not over load the service power supplies. The current consumption for all the units for never exceed the out put capacity for the service power supplied. Disconnect from the connection units if the units start to over load or over heat.
How should the wiring be assembled for a basic AC type unit?
There is a diagram in the manual 96M0364 in Chapter 2 System Installation 1-67 page 91. The manual can help figure out how to hook up the wiring for a basic AC unit, but some notes from the manual explain that it should be connected by an insulated transformer and have a noise filter. Also twisted cables should be used to reduce effects of induction. There is also a diagram of how wiring for a basic DC type unit, if needed.
