Solutions
• 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)
• 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
For safety reasons, the IP address of the 7KN Powercenter 1000 can only
be entered manually via a VPN connection
Check the system time of the 7KN Powercenter 1000 and re-synchronize
the time with the mobile terminal device or check the SNTP server
• 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
Confirm the tripping operation with a short button press
• 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
may occur soon)
