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.

Local acceleration logic ZCLCPLAL

Prepare the IED for verification of settings as outlined in
verify settings".
Values of the logical signals for ZCLCPLAL are available on the local HMI under
Main menu/Tests/Function status/Scheme communication/ZCLCPLAL/
1:ZCLCPLAL. The Signal Monitoring in PCM600 shows the same signals that are
available on the local HMI.
The logic is checked during the secondary injection test of the impedance measuring
zones.

Verifying the settings

1. Provide the IED with conditions equivalent to normal load for at least two seconds.
2. Deactivate the conditions for accelerated function.
3. Apply a phase-to-ground fault at 100% of line impedance.
4. Check that the fault is tripped with the second zone time delay.
5. Provide the IED with conditions equivalent to normal load for at least two seconds.
6. Activate the condition for accelerated function either by the autorecloser or by the
loss-of-load.
7. Apply a phase-to-ground fault at 100% of line impedance.
8. Check that the fault is tripped instantaneously.

Completing the test

Continue to test another function or end the testing by setting the parameter TestMode
to Disabled 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/Scheme communication/ZCLCPLAL/1:ZCLCPLAL 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.
