Why does ATS48 not operate when wired like the recommended diagram on page 74 of the June 2002 manual?
The user's manual recommended diagram on page 74 is incorrect for proper operation.
On line 2 of the ladder diagram after fault relay R1A to R1C connection the coil that is labeled TR for trip relay should be a FR coil for fault relay.
Then should add a line after this that has a NC (normally closed ) FR ( fault relay ) contact in series with a TR ( trip relay ) coil.
This configuration would then allow proper operation of unit.
