Emergency Stop switch

The Emergency Stop switch is integrated in the charging station's safety loop. If the following
is present and set up, then a message is sent to the following locations when the emergency
shutdown switch is activated:
• To the SCB. See section "SICHARGE Configuration Backend (Page 58)"
• To the OCPP backend of the operator. See section "OCPP backend (Page 60)"
During the emergency stop, the following is switched off:
• Rotating parts such as the main fan and cooling unit fan are switched off
• The power lines for charging are switched off
• The quick shutdown of the converters is started
• The circuit breaker of the converters is switched off
• The DC outlet contactors to the vehicle are opened
• The interlocks of the charging plugs on the charging station are released.
• Optional AC charging socket and charging outlets to the dispenser are switched off
The auxiliary circuit with controller and touch screen remains active during the emergency
stop. The following functions therefore continue to be active:
• Touch screen
• Communication to the backend
• Auxiliary fans in the automation area to protect against overtemperature
The LED strips of the charging station light up red. You cannot charge in emergency stop
state. The message "Emergency stop triggered" appears on the touch screen of the charging
station.
The charging station returns to its normal operating state after the emergency switch has
been unlocked. See section "Safety loop and emergency stop (Page 25)"
