Symptoms

Standard Product ATO (Automatic Throw Over) Control Tool does not sensitize the "Disable and Set ATO to Alternate Feeder".

We have configured a pair of ATOs, Primary and Alternate, and are using the standard product Control Tool for these.

The primary and secondary ATO devices are identified and linked together.  The control function is defaulted to 2dev - which means it will have manual return instead of auto return.  Three other parameters can be configured which specify the delay in operation of the primary ATO, the secondary ATO, and between primary and secondary ATOs.  These parameters have default values (0 = no delay).

The primary ATO device has an "Operations | ATO Device Actions" option on the Control Tool.  ATO Device Actions has a sub-menu with the option: Disable and Set ATO to Alternate Feeder.  That option is de-sensitized and cannot be selected.  The alternate ATO device does not have the ATO Device Actions option.

A snippet from the Control Tool config says:

 
This looks like it will not be enabled when the primary ATO is closed and the secondary ATO is open, i.e. the normal state.  It is expected that if the alternate (secondary) ATO, the secondary, that the "Disable and Set…" action would be sensitized, but it is not.  The expectation is that the "Disable and Set ATO to Alternate Feeder" option be sensitized in particular scenarios.
