Operation - Siemens SINAMICS DCM Betriebsanleitung

Operation

The following operator controls are built into the cabinet door:
AOP30 Advanced Operator Panel
Detailed information on operation (incl. fundamentals and control via the AOP30 advanced
operator panel) can be found in the SINAMICS DCM DC Converter Operating Instructions
under the Chapter "Operation".
Control voltage switch
Switching on the control voltage switch activates the auxiliary supply in the cabinet. All
components in the cabinet and all outgoing feeders, e.g. for the motor fan, are then supplied
with voltage.
If the control voltage switch is in "I" position , the cabinet door can no longer be opened.
Disconnecting the control voltage switch ensures that no voltages are fed downstream of the
control voltage switch or the main contactor (circuit breaker).
Note
Disconnecting the control voltage switch in operation can cause contactors to drop out and
fuse components to be disconnected.
E-STOP button
The button is locked when pressed and is unlocked when it is pulled out.
Response when the pushbutton is pressed:
● Pressing the button causes immediate, hardware-determined disconnection of the main
contactor or circuit breaker. Disconnection occurs independently of semiconductor
devices and independently of any faulty functionality in the control electronics or in the
power module of the SINAMICS DCM DC Converter.
● The display of operating state on the AOP30 advanced operator panel changes to
"OFF2".
If an E-STOP occurs in operation status, the display changes operating state to
"Switching On Inhibited".
● The display of operating state on the SINAMICS DCM DC Converter changes to 10.3.
If an E-STOP occurs in operation status, the display changes operating mode to 8.0.
