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