If Line 1 (= the normal line) comes back, after the set time delay (TBS) the ATS022 sends an opening command to the protection device on the emergency line and the closing command to the protection device on the normal line is executed after a set time delay (TCN). - Page 14 Protection devices do not respond Opening Command During the switching sequence, the ATS022 sends the opening command to the protection device on the normal line. If this is not effectively opened in fi ve seconds, the “Open 1 Failure” alarm is activated and the Alarm LED will be switched ON.
