Not that I am sure they are correct in the first place*, but the current logic in Rungs 001 and 002 can be replaced by a single rung. Is there a second pressure switch with a lower setpoint? (whoops, never mind, yes cf. How is it determined that 2 compressors need to be on? both compressors off when there is adequate pressure (I:1/2 is 0), and 1 or 2 compressors on when there is inadequate pressure (I:1/2 is 1)? Logix 5000? (whoops, never mind, LogixPro in your title).
I am not sure we know enough about the processĬan you provide a schematic and a summary of inputs (pressure switches, momentary push buttons, switches, etc., and outputs)?
