Any function is blocked if the corresponding setting in the local HMI
under
Main menu/Test/Function test modes
menu remains
Enabled
,
that is, the parameter
Blocked
is set to
Yes
and the parameter
TestMode
under
Main menu/Test/IED test mode
remains active. All functions that
were blocked or released in a previous test mode session, that is, the
parameter
Test mode
is set to
Enabled
, are reset when a new test mode
session is started.
Procedure
1.
Click the
Function test modes
menu.
The Function test modes menu is located in the local HMI under
Main menu/Test/
Function test modes
.
2.
Browse to the function instance that needs to be released.
3.
Set parameter
Blocked
for the selected function to
No
.

Verifying analog primary and secondary measurement
Verify that the connections are correct and that measuring and scaling is done correctly.
This is done by injecting current and voltage to the IED.
Besides verifying analog input values from the merging unit via the IEC 61850-9-2-LE
process bus, analog values from the transformer input module can be verified as follows.
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.
