ACS550 User's Manual

Application macro: Hand-Auto

This macro provides an I/O configuration that is typically used in HVAC applications.
To enable, set the value of parameter 9902 to 5 (
Note! Parameter 2108
Connection example:
• Two analog references (AI1, 2)
• Start/stop – hand/auto (DI1, 6)
• Direction – hand/auto (DI2, 5)
• Control location selection (DI3)
• Run enable (DI4)
