Question
Why does my 3422 conductivity sensor not read correctly when connected through a gateway but does when connected to a module for my sc200 controller?
Summary
Model 3422 conductivity sensor wiring details.
Answer
There was a time when the sticker that labels the wiring terminals was placed backwards on the gateway terminal strip. Only a small amount of the gateways are affected but the mistake in production can cause confusion when wiring the sensor to the gateway. The attached document shows the correct layout.
