The closing STOP signal is provided for resetting K2 on the SU-control circuit. It effects with priority in switching<br />
OFF (by ST or UVR) before switching ON. Once switching ON and OFF signals are simultaneous, switching OFF<br />
command will stay longer than switching ON. It means, that OFF command is master command.<br />
-S2 (-X2 :6/:7) is NO contact, utilized for indirect releasing of the UVR by relay -K2<br />
-S2 (-X2 :8/:9) is NC contact utilized for direct releasing of the UVR. If it’s not used, please short this connection<br />
permanently.<br />
