Led Signaling Of The Sentron Circuit Protection Devices - Siemens Sentron 7KN POWERCENTER 1000 Manual

LED signaling of the SENTRON circuit protection devices

The circuit protection devices with metering and communication function can display
different statuses with the LEDs. The 3NA COM fuse is an exception here as well; it has no
LEDs. The status of the fuse can only be read out using the communication function.
In the following table the 7KN Powercenter 1000 distinguishes between the two LEDs ACT
and COM. A ✓ would mean that both LEDs have this function. Similarly, the 5SV6 COM arc
fault detection device also has two LEDs, a left one for the arc fault detection device part and
a right one for the miniature circuit breaker part of the device. The ✓ shows that both have
this function.
Description
Device without power supply
applied, function not provided
Device in working condition,
function possible without re-
strictions
No radio connection to the
7KN Powercenter 1000 or no
connection to terminal devices
Internal process running, e.g.
setting up a connection, firm-
ware update, reset has started
(change to flashing at 10 Hz
after 10 s)
Device location mode has been
activated
Warning of an upper limit viola-
tion (e.g. temperature, current
or voltage)
Warning end of service life (e.g.
operating hours, switching
cycles, tripping operations)
Manual switching off of the
main unit
Communication error or device
error, e.g. self-test unsuccessful
Circuit protection device itself
or attached circuit protection
device has tripped
For example, a 2 Hz flashing frequency corresponds to a flashing of 2-times per second. In comparison, a 5 Hz flash (5
1)
times per second) is faster
Resetting is displayed on the COM LED, the rest on the ACT LED
2)
A communication error is displayed on the COM LED, the rest on the ACT LED
3)
Device identification can be activated using the software. In the powerconfig app for
example, tapping the device image in the identification view puts the device into device
localization mode for 10 seconds with 5 Hz flashing.
