Title: First Stage is Active All the Time H2-DM1E V2.10.4
Post by: Saturn_Europa1 on April 29, 2026, 10:40:09 AM

I am using a SGSET instruction to Enable S1 of a program.  When a pump turns on it actives NO bit that turns SGSET Enable Stage 1 to true.  Even when the pump is off an NO stays open, S1 will be on the entire time.  Any ideas?

Once you turn on the stage using SGSET it will stay on even if your NO switch turns back off. You need to use the SGRST instruction to turn off S1 once the pump turns off.
