No ECHO and TRWEI should appear.
14. Switch the current off and check that the ECHO, CS and TRWEI appear on
the corresponding binary output during 200ms after resetting the directional
element.
15. Switch the polarizing voltage off and reset the CRL binary input.
10.10.4.3 Completing the test
M13936-90 v5
continue to test another function or end the test by changing the TESTMODE
setting to Off. Restore connections and settings to their original values, if they were
changed for testing purposes.

10.11.1 Tripping logic
GUID-C358A2CF-5F7C-4381-B082-AB54965FC453 v2
Prepare the IED for verification of settings outlined in Section
"Preparing the IED
to verify settings".
This function is functionally tested together with other protection functions (line
differential protection,earth-fault overcurrent protection, and so on) within the IED.
It is recommended that the function is tested together with the autorecloser
function, when built into the IED or when a separate external unit is used for
reclosing purposes. The instances of SMPPTRC are identical.
10.11.1.1 Test for trip
GUID-6F9F9CE1-366F-40B6-8EF1-A096D89C11B8 v2
1. Check that AutoLock and TripLockout are both set to Off.
2. Initiate faults one at a time.
An adequate time interval between the faults should be considered, to
overcome a reclaim time caused by the possible activation of the auto recloser
function SMBRREC. The function must issue a trip in all cases, when trip is
initiated by any protection or some other built-in or external function.
10.11.1.2 Circuit breaker lockout
GUID-5405250B-C172-40E1-8275-06BF8A984D67 v2
The following tests should be carried out when the built-in lockout function is used
in addition to possible other tests, which depends on the complete configuration of
an IED.
