Checking the power supply
M11725-2 v4.1.1
Insert only the corresponding male connector to the female connector.
Inserting anything else (such as a measurement probe) may violate 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 powering the IED.

Energizing the IED
4.4.1
Checking the IED operation
M11726-2 v6
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. This could be done in a number of ways,
from energizing a whole cubicle to energizing a single IED. Set the IED time if no time
synchronization source is configured. Check the self-supervision function in Main menu/
Diagnostics/Internal events or Main menu/Diagnostics/IED status/General menu in local
HMI to verify that the IED is functioning properly.
4.4.2
IED start-up sequence
M11727-3 v9
The following sequence is expected when the IED is energized.
•
The green Ready LED starts flashing instantly and the ABB logo is shown on the LCD.
•
After approximately 30 seconds, "Starting" is shown on the LCD.
•
Within 90 seconds, the main menu is shown on the LCD and the green Ready LED shows a
steady light, which indicates a successful startup.
The startup time depends on the size of the application configuration.
Application configurations with less functionality have shorter startup times.
If the green Ready LED continues to flash after startup, the IED has detected an internal error.
Navigate via Main menu/Diagnostics/IED status/General to investigate the error description.
