Energizing The Ied; Checking The Ied Operation; Ied Start-Up Sequence - ABB Relion 670 Series Commissioning Manual

Section 4
Starting up
Check that the auxiliary supply voltage remains within the permissible input voltage range under all
operating conditions. Check that the polarity is correct before energizing the IED.

Energizing the IED

4.4.1

Checking the IED operation

Check all connections to external circuitry to ensure correct installation, before energizing the IED
and carrying out the commissioning procedures.
Energize the power supply of the IED to start it up. Keep the DC power supply on until the Root
menu or the selected default screen is shown on the HMI before interrupting the DC power supply
again. The energization could be done in a number of ways, from energizing a whole cubicle with
many IEDs to energizing each single IED one by one.
If HW (i.e. I/O and/or communication boards etc.) have been changed (i.e. removed, replaced, or
added), the user should re-configure the IED by navigating in the local HMI menu to: Main menu/
Configuration /Reconfigure HW modules to activate the changed hardware modules in order to
enable the self-supervision function to detect possible hardware errors.
Check also the self-supervision function in Main menu/Diagnostics/IED status/General menu in
local HMI to verify that the IED operates properly.
Set the IED time if no time synchronization source is configured.
To ensure that the IED is according to the delivery and ordering specifications documents delivered
together with each IED, the user should also after start-up use the built in HMI to check the IED's:
• Software version, Main menu /Diagnostics/IED status /Product identifiers.
• Serial number, Main menu /Diagnostics/IED status /Product identifiers.
• Installed modules and their ordering number, Main menu/Diagnostics /IED status/Installed
HW .

IED start-up sequence

When the IED is energized, the green LED starts flashing instantly. After approximately 55 seconds
the window lights up and the window displays 'IED Startup'. The main menu is displayed and the
upper row should indicate 'Ready' after about 90 seconds. A steady green light indicates a
successful startup.

1 IED energized. Green LED instantly starts flashing
2 LCD lights up and "IED startup" is displayed
3 The main menu is displayed. A steady green light indicates a successful startup.
If the upper row in the window indicates 'Fail' instead of 'Ready' and the green LED flashes, an
internal failure in the IED has been detected.
