The functional output TRIP should be active at each fault. The output
CLLKOUT must not be set.
3.
Activate the automatic lockout function, set
AutoLock
=
On
and repeat
Beside the TRIP outputs, CLLKOUT should be set.
4.
Reset the lockout signal by shortly thereafter activating the reset lockout
(RSTLKOUT) signal.
5.
Activate the TRIP signal lockout function, set
TripLockout
=
On
and repeat.
The output TRIP must be active and stay active after each fault, CLLKOUT
must be set.
6.
Repeat. Reset the lockout.
All functional outputs should reset.
7.
Deactivate the TRIP signal lockout function, set
TripLockout
=
Off
and the
automatic lockout function, set
AutoLock
=
Off
if not needed.
6.8.1.3
Completing the test
Continue to test another function or end the testing by setting the parameter
TestMode
to
Off
under
Main menu/Tests/IED test mode/1:TESTMODE
. If
another function is tested, then set the parameter
Blocked
to
No
under
Main menu/
Tests/Function test modes/Logic/SMPPTRC(94,1->0)/X:SMPPTRC
for the
function, or for each individual function in a chain, to be tested next. Remember to
set the parameter
Blocked
to
Yes
, for each individual function that has been tested.

Testing monitoring functions
6.9.1
Event counter CNTGGIO
The event counter function CNTGGIO can be tested by connecting a binary input
to the counter under test and from outside apply pulses to the counter. The speed of
pulses must not exceed 10 per second. Normally the counter will be tested in
connection with tests on the function that the counter is connected to, such as trip
logic. When configured, test it together with the function that operates it. Trig the
function and check that the counter result is the same the number of operations.

Testing metering functions
6.10.1
Pulse counter PCGGIO
The test of the Pulse counter function PCGGIO requires the Parameter Setting tool
in PCM600 or an appropriate connection to the local HMI with the necessary
functionality. A known number of pulses with different frequencies are connected
to the pulse counter input. The test should be performed with settings
Operation
=
On
or
Operation
=
Off
and the function blocked or unblocked. The pulse counter
value is then checked in PCM600 or on the local HMI.
