I've just read the manual for your ATS. It functions independently of the Ems. The logic to determine the source is in the Iota device.
The device is designed to connect the shore power. If it senses generator power, it will switch to the generator input after a time delay. The generator has preference if it is running.
That everything works when connected to the generator tells us that everything from the ATS output is good.
Test without the generator running. The two likely problems are;
1 there is no voltage from the pedestal. The correct place to measure are the terminals, hot 1 and hot 2 power cord in the ATS itself. Get some help if you are not comfortable doing this.
2 if you are sure there is voltage at the input to the ATS, the one of the transfer relays is stuck, or the contacts welded. It will need replacement.
According to the manual, the switch you mentioned is the timer bypass switch and should be in position 1 for normal use. The timer makes sure the generator is up to speed before transferring. If the timer circuit fails, the switch allow transfer as soon as generator voltage is sensed.
I'm may be possible to hear the relays click when you shut off generator power as they drop back to the de-energized position. One relay transfers the neutral, and the other transfers the hot wires.
