Avoiding Non‑Operational Conditions

Non Operational, Both Systems Disabled and Non‑Operational, System A is Menu Selected, but Faulted show that it is best to leave the Switching Menu > Auto Switch enabled at all times.

To place a system in maintenance mode, it is recommended that the hardware switch be used.

If absolutely necessary, you can use the Switching Menu to disable a system temporarily until someone can go to the radar site and set the hardware A/B switch.

The only other reason for selecting A or B in the Switching Menu is to force the systems to switch to “even‑out” or test the usage of each system. After the switch is forced, you should immediately re-enable the Auto Switch .
