Checking the power supply
M11725-2 v6
Do not insert anything else to the female connector but the corresponding
male connector. Inserting anything else (such as a measurement probe) may
damage the female connector and prevent a proper electrical contact between
the printed circuit board and the external wiring connected to the screw
terminal block.
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
M11726-2 v7
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.
4.4.2
IED start-up sequence
M11727-3 v11
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.
