How can I use PID controls on an E-Flex or M-Flex that has an HOA switch?

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.
