Function of the switch
The function of the switch is described in detail in section 3.3 "Display elements and operator
controls" (Page 29).
Revoking the Emergency Stop
Note
Eliminate the hazardous situation
First eliminate the hazardous situation when you want to revoke the Emergency Stop.
If the Emergency Stop was triggered by the switch at the charging station, it can be revoked
again with this switch. The switch is equipped with a rotate-to-unlatch mechanism. An arrow
on the top of the button indicates the direction of rotation for unlatching. Instructions are
also shown on the display.
The charging station automatically starts to restore charging readiness after it is unlocked.
This may take a few minutes. The LED strips signal this process and light up in white. After a
successful self-check, the LEDs light up green. The start menu is shown on the display. The
charging station is back in normal operating mode.
Misuse of the switch during operation
To prevent the repeated (misused) actuation of the switch and thus the failure of the
charging station without a safety-related reason, a waiting time is initiated when the switch
is actuated during operation. This starts after the switch is unlocked. Once the waiting time
has elapsed, the charging station starts to restore its readiness. This waiting time can be
individually set in the SICHARGE Configuration Backend (SCB) (see section 3.13 "SICHARGE
Configuration Backend" (Page 53)).
Integration into an existing safety loop
With this option the charging station has additional terminals in its input area which act as an
interface for integration of an existing system safety loop (designed as Normally Closed, NC).
Interrupting the external safety loop triggers the Emergency Stop of the charging station. For
more information, see next section (Page 45).
Integration of an external load management system
In the event of a fault, the load management system must be able to switch the charging
station to emergency shutdown in order off to protect the network against overload. An
interface to the internal safety loop of the charging station is also required for this purpose.
For more information, see next section (Page 45).
