Description
3.3 Display elements and operator controls
Emergency stop switch
The emergency stop switch is integrated in the charging station's emergency stop loop.
Pressing the switch sends a message to the Siemens Configuration backend (charging station
management system for configuration purposes and detailed error analyses, see also
section 3.9) and to the OCPP backend of the operator (management system with small
functional scope, see also section 3.10), if it is present and the functionality is integrated.
In addition to the rotating parts (fans), the power lines for charging are also set to the safe
emergency stop state. The charging station controller initiates emergency shutdown of the
AC/DC converters, releases their power supply via the circuit breaker, and opens the DC outlet
contactors to the vehicle. The release of the circuit breaker also ends charging via the AC
charging socket and dispenser (remote and non-autonomous charging points). Existing
interlocks of the charging plug are released by the charging station. The LED strips of the
charging station light up red. Charging is not possible in the emergency stop state. The "Out
of service" message remains on the display of the charging station.
The auxiliary power circuit with control system and touch screen remains active in emergency
stop state. This means that communication to the backend is maintained. The touch screen
displays information on the current state of the charging station. The charging station can
return to the normal operating state once the switch is unlocked.
AC meter (charging outlet)
Below the viewing window of the DC meter on the right is the window with the display of the
AC meter for the electricity dispensed at the AC charging socket. Please refer to the operating
instructions on the use of the device for more information on the contents displayed. Take
the exact device type from the parts list of your charging station.
