Issue:
Trying to setup PID control on an ATV61/71 with a HOA switch.
Product Line:
ATV61/71, E-Flex, M-Flex
Environment:
All of the ATV61/71, E-Flex, M-Flex
Cause:
None
Resolution:
To allow PID control in Auto mode and manual reference control in HAND, the logic input for PID AUTO/MAN or reference 2 switch must be setup so that the contact is closed in HAND mode and open in AUTO mode. The logic input causes the manual control to override the PID.
