Application Macro: PFC

This macro provides parameter settings for pump and fan control (PFC) applications.
To enable, set the value of parameter 9902 to 7 (
Note! Parameter 2108
Connection example:
• Analog ref. and actual (AI1, 2)
• Start/stop – manual/PFC (DI1, 6)
• Run enable (DI2)
• EXT1/EXT2 selection (DI3)
• Interlock (DI4, 5)
