4.3.7 Zero voltage releases 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.
