Discovery mode, which SMA calls TS4 detection, is the commissioning step in which the SMA inverter uses the Gateway Interface Board and the rooftop Gateways to search for the TS4-R devices installed on the array. You start it by clicking Find and Save in the inverter's Installation Assistant. Run the gateway test first. If the Gateways are not detected within 10-15 minutes, go ahead with TS4 detection anyway. On average, detection takes 10 to 60 minutes. The time depends on how many TS4-R devices are installed and how strong the signal is between the Gateways and each device. While detection is running, the inverter shows Commissioning Status Active, and the green and amber LEDs on the Gateway Interface Board flash alternately. This is normal and needs no action. When detection is finished, Commissioning Status changes to OK and green checkmarks appear. You can then confirm that every TS4-R device is listed and reporting under Instantaneous Values, in the Modular Technology section. The first time devices are detected, they may drop offline for a short time while they update their firmware. This takes about 5-15 minutes and is expected. Once the devices are detected and communicating, check that Rapid Shutdown Mode is set to TS4 Shutdown. That mode does not cover TS4-R-F devices, which need SunSpec Shutdown instead. If devices still do not communicate after detection, check the registered serial numbers against the rooftop map. Make sure every device has a clear line of sight to a Gateway within 25 to 30 ft and that cable connections are secure. Then run detection again.
<!-- review notes
- sentence 1: support check: partial - TS4 detection via Find and Save in the Installation Assistant is stated, but the 'discovery mode' naming equivalence is not in the passage.
- sentence 4: support check: partial - Active status and alternating green/amber GIB LEDs are stated, but that this is normal and needs no action is not explicitly stated.
- sentence 1: review: partial - The passage supports TS4 detection run from Find and Save in the Installation Assistant using the GIB and rooftop Gateways to find TS4-R devices, but it never says this is also called 'discovery mode'.
- sentence 4: review: partial - Commissioning Status Active and the alternating green and amber GIB LEDs during detection are stated, but the passage never says this is normal and needs no action.

Tigo TS4 platform proposed
TS4 detection is the commissioning step that finds TS4-R devices through the SMA Gateway Interface Board and the rooftop Gateways.
review note: support check: partial - Passage describes TS4 detection finding TS4-R devices via the GIB and Gateways, but nothing about 'discovery mode' or it being part of the Tigo TS4 platform (prod:tigo-ts4).; review: partial - The note is supported (TS4 detection via 'Find and Save' finds TS4-R devices through the GIB and Gateways), but the passage presents it as a step in the SMA inverter Installation Assistant and never calls it a 'discovery mode' or…
