Configurator
Program blocks are stored in the library without I/Os. Use the auto-create and auto-connect functions to create I/Os and/or to connect them to the interface blocks, e.g., R_A, CMD_B. Alternatively, take the I/Os from the folder containing the predefined I/Os in the library and/or from the plant and connect them to the interface blocks.
Controls a 1-speed pump.
This program block has the following optional functions:
Option: Fault (1xBI)
Reads the fault signal from the pump control unit and generates an alarm.
Option: Feedback (1xBI)
Reads the feedback signal, e.g., from a pump control unit, and generates an alarm if feedback is missing when the pump must run.
Option: Flow detector (1xBI)
Reads the signal from a flow detector and generates an alarm if flow is missing when the pump must run.
Option: Kick function
Prevents standstill damage by generating a pulse that starts the pump at a configured time with a defined pulse length after a minimum off time has elapsed.
This is configured in the program.
Option: Maintenance switch (1xBI)
Reads the signal from the maintenance switch and generates an alarm. If active, then the outputs of the pump are stopped with very high priority (priority 2).
