9.1 Error on commissioning 
  Circuit protection devices with communication and metering function 
84  System Manual, 06/2021, L1V30827018B-01 
7KN Powercenter 1000 no longer provides any 
data after commissioning 
•  Check whether the mobile device is also connected to the same net-
work as the 7KN Powercenter 1000 
•  Check whether the 7KN Powercenter 1000 has received another IP 
address, by carrying out the WLAN search again 
•  Check the power supply. Are the LEDs illuminated? 
•  Unplug and plug the Ethernet cable on the 7KN Powercenter 1000 
•  Restart the devices (Disconnect power supply or switch off devices 
using the operating lever) 
The devices no longer deliver any data 
•  Check the functioning communication to the 7KN Powercenter 1000. Is 
the data transceiver providing values? 
•  Check the power supply and the LEDs 
•  Restart the devices (disconnect power supply or switch off devices) 
•  Disconnect the terminal device from the 7KN Powercenter 1000 via a 
long button press on the terminal device or carry out the Decouple 
function with the app and pair the terminal device again 
WLAN search is not finding any devices with 
the existing VPN connection 
For safety reasons, the IP address of the 7KN Powercenter 1000 can only 
be entered manually via a VPN connection 
Time line of the trends and time stamp of the 
messages do not match 
Check the system time of the 7KN Powercenter 1000 and re-synchronize 
the time with the mobile terminal device or check the SNTP server 
Devices flash yellow permanently (device 
error)  
•  Switch power supply or device on and off 
•  Remove possible radio interference to rectify a communication error 
•  Resetting via a long button press ≥ 10 s to exclude communication 
error 
 
Replace devices if device error persists 
Device flashes red continuously (tripping op-
eration active) 
Confirm the tripping operation with a short button press 
Device flashes green/yellow (warning limit 
value) or yellow/red (warning end of service 
life) 
•  Check the active alarm messages 
•  Check the alarm parameters that are switched on and their threshold 
values (increase threshold value if necessary) 
•  Check the condition of the final circuit (an overload tripping operation
