Apply input signals as needed according to the actual hardware and the
application configuration.
1. Inject a symmetrical three-phase voltage and current at rated value.
2. Compare the injected value with the measured values.
The voltage and current phasor menu in the local HMI is located under Main menu/
Measurements/Analog primary values and Main menu/Measurements/Analog
secondary values.
3. Compare the frequency reading with the set frequency and the direction of the
power.
The frequency and active power are located under Main menu/Measurements/
Monitoring/ServiceValues(MMXN)/CVMMXN:x. Then navigate to the bottom
of the list to find the frequency.
4. Inject an unsymmetrical three-phase voltage and current, to verify that phases are
correctly connected.
If some setting deviates, check the analog input settings under
Main menu/Configuration/Analog modules
If the IEC/UCA 61850-9-2LE communication is interrupted during
current injection, the report tool in PCM600 will display the current that
was injected before the interruption.
