Why do Emerson numatics g3 outputs remain on when communication is lost?
Outputs may remain on due to incorrectly set Communication Fault parameters. Verify that the communication fault/idle mode parameter setting is not set to 'Hold Last Output State'.
What to do if there is no output power on the Emerson numatics g3 Auxiliary Power connector?
Check for 24VDC on the +24 VDC (Valves and Outputs) pin of the MINI Auxiliary Power connector of the Comm. module.
