Question
Are there any points to look out for when changing over from 61F-APN Alternate Operation Relays to 61F-APN2?
Answer
61F-APN and 61F-APN2 differ in outer dimensions, so the compatible Sockets and the mounting method will be different. This means that the Sockets must also be replaced, and the terminal arrangement will be reversed, so the wiring will have to be changed as well.
 Why do the specifications for the High-sensitivity 61F Floatless Level Controller say, "possible to use with 15 kOHM or less, however, this may cause reset failure"?
