Description

The FB_Phasenwaechter function block monitors three phases and detects the failure of individual conductors. The status is reported back via realistically simulated contacts (NC contacts 13–14 / NO contacts 21–22): As long as all three phases are present, the NC contact is activated; if at least one phase fails, the NO contact switches. Inputs serve as enable signals, so that the output is only generated when the input is set. The block supports reset and deactivation.

Note: This logic is intended as a template. Before productive use, it must be integrated, tested, and approved by qualified personnel. Incorrect integration may result in incorrect display or undesirable switching behavior.

How it works
Reset

With #Reset the internal failure indicator #fail is reset so that the module again assumes a full three-phase state.

Disabled

If #Enable is not set, both contacts are deactivated. The block does not report an error; the status indicates a neutral state.

Phase failure test

The block checks whether all three phases ( #PhaseA , #PhaseB , #PhaseC ) are present. If one or more are missing, #fail is set.

Contact logic

The outputs only react if the corresponding inputs are enabled:

  • #NO_13_14 (normally closed) is active if #Input_13 is set and no phase is missing.
  • #NC_21_22 (normally open) is active if #Input_21 is set and at least one phase has failed.
Technical details
  • Inputs: #Enable , #Reset , #PhaseA , #PhaseB , #PhaseC , #Input_13 , #Input_21
  • Internal state: #fail – TRUE if at least one phase is missing
  • Outputs: #NO_13_14 (normally closed when complete), #NC_21_22 (normally closed when failure occurs)
  • Status & Diagnosis: #Error , #Status , #DiagnosticCode
  • Logic: Real-time phase failure detection with conditional contact release
  • Modes: Reset, Disabled, Normal Operation
Possible applications
  • Monitoring three-phase systems for phase failure
  • Protection of motors, generators and transformers through early detection of missing phases
  • Integration into control and safety logic with feedback via opener/closer
  • Simulation and testing through input releases without real load

Note: A complete technical inspection and approval by qualified personnel is required before productive use.
