4. Test of CB contact travel time
4.1. Test the set timing defined by OpenTimeCorr, CloseTimeCorr, tTrOpenAlm and tTrCloseAlm.
4.2. Change the status of the auxiliary contacts such that travel time to open TTRVOP and travel
4.3. Check that TRVTOPAL and TRVTCLAL are activated.
5. Test of CB status
5.1. Test the set current level defined by AccStopCurr.
5.2. Check the CLOSEPOS output by changing the POSOPEN to 0 and POSCLOSE to 1.
5.3. Check the OPENPOS output by changing the POSOPEN to 1 and POSCLOSE to 0 and also
5.4. Check the circuit breaker is in INVDPOS if auxiliary contacts read same value or CB is open
6. Test of remaining life of CB
6.1. Test the set timing defined byRatedOperCurr, RatedFltCurr, OperNoRated, OperNoFault,
6.2. Vary the phase current in the selected phase from below rated operated current,
6.3. The remaining life of CB output CBLIFEPH is estimated when the CB is changed from closed
6.4. CBLIFEAL is activated as soon as CBLIFEPH is below the set CBLifeAlmLevel value.
7. Test of accumulated energy
7.1. Test the actual set values defined by AccSelCal to Aux Contact, ContTrCorr and
7.2. Inject phase current in the selected phase such that its value is greater than set AccStopCurr
7.3. When the breaker goes to open position, accumulated energy IPOWPH is calculated. The
7.4. Alarm signal IPOWALPH appears when IPOWPH is greater than set AlmAccCurrPwr value.
7.5. Lockout signal IPOWLOPH appears if IPOWPH exceeds further to the threshold value
7.6. Calculation of accumulated energy IPOWPH is stopped when injected current is lower than
8. Test of CB operation cycles
8.1. Test the actual set values defined by OperAlmLevel and OperLOLevel.
8.2. The operation counter, NOOPER is updated for every close-open sequence of the breaker by
8.3. OPERALM is activated when NOOPER value exceeds the set OperAlmLevel value. The
8.4. OPERLO is activated when NOOPER value exceeds the set OperLOLevel value.
9. Test of CB spring charge monitoring

measured travel time for opening and closing is shown on TTRVOP and TTRVCL respectively.
inject the current in the selected phase slightly lower and higher than AccStopCurr set value.
Only for a current lower than set AccStopCurr should activate the output POSOPEN.
