Section 7 Energizing the IED
About this chapter
This chapter describes the start-up sequence and what to check once the IED has
been energized.
7.1
Check the IED operation
Check all connections to external circuitry to ensure that the installation was made
correctly, before energizing the IED and carrying out the commissioning procedures.
The user could also check the software version, the IED's serial number and the
installed modules and their ordering number to ensure that the IED is according to
delivery and ordering specifications.
Energize the power supply of the IED to start it up. This could be done in number
of ways, from energizing a whole cubicle to energizing a single IED. The user
should re-configure the IED to activate the hardware modules in order to enable the
self supervision function to detect possible hardware errors. The IED time must be
set. The self-supervision function in the Main menu/Diagnostics/Monitoring
menu in local HMI should also be checked to verify that the IED operates properly.
7.2 Energizing the IED
When the IED is energized, the green LED instantly starts flashing. 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.
