Application macros
Hand-Auto macro
This macro provides an I/O configuration that is typically used in HVAC applications.
To enable, set the value of parameter 9902 to 5 (
HAND/AUTO).
Note: Parameter 2108 START INHIBIT must remain in the default setting, 0 (OFF).
Connection example:
Input signals Output signals Jumper setting
• Two analog references (AI1, 2)
• Start/stop – hand/auto (DI1, 6)
• Direction – hand/auto (DI2, 5)
• Control location selection (DI3)
• Run enable (DI4)
• Analog output AO1: Speed
• Analog output AO2: Current
• Relay output 1: Ready
• Relay output 2: Running
• Relay output 3: Fault (-1)
