Operation of the SENTRON circuit protection devices

The circuit protection devices with metering and communication function have different
operating options in addition to the communication function.
5SL6 COM / 5SV6 COM
Only the 3NA COM fuse has neither LEDs for status display nor operating options on the
device itself. The operation for this only works via the communication interface and a
corresponding software, such as the SENTRON powerconfig app.
The following options are provided:
Description
Activating the Bluetooth mode (COM LED flashes with
2 Hz) or disconnecting an active Bluetooth connec-
tion
Confirming a tripping operation
Executing a test button trigger/self-test
Resetting the radio or Bluetooth communication
information
(LED flashes after the first 3 s with 2 Hz for an addi-
tional 7 seconds. Then fast at 10 Hz for 2 s, which
signals the end of resetting)
Switching the device on/off
The activation of the Bluetooth mode or disconnecting an active Bluetooth connection is
described in the Chapter Bluetooth interface (Page 33).
If a 5SL6 COM circuit breaker or a 5SV6 COM arc fault detection device has tripped (overload,
short-circuit or arcing fault), the device is switched off and the lever is in the off position;
communication is not possible in this state. In order to switch on the device again, the lever
needs to be pulled up to the On position. Communication is then possible and the LEDs
indicate that the device has tripped via its protection function by flashing red. In order to
acknowledge this flashing, the tripping operation has to be confirmed with a short button
press.
