Cause : Input pressure supervision comes when the supervision signal of the input pressure (P3.13.9.2) is lower than the alarm limit (P3.13.9.7) or the supervision signal of the input pressure (P3.13.9.2) is lower than the fault limit (P3.13.9.8).

  • Do a check of the process.
  • Do a check of the parameters in menu M3.13.9.
  • Do a check of the input pressure sensor and connections.
