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
5.4. Check the circuit breaker is in INVDPOS if auxiliary contacts read same value or CB is
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
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
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
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
9.1. Test the actual set value defined by SpChAlmTime.
9.2. Enable SPRCHRST input. Also activate SPRCHRD after a time greater than set time
9.3. At this condition, SPCHALM is activated.
10. Test of CB gas pressure indication
10.1. Test the actual set value defined bytDGasPresAlm and tDGasPresLO.
10.2. The output GPRESALM is activated after a time greater than set time of tDGasPresAlm
10.3. The output GPRESLO is activated after a set time of tDGasPresLO value if the input
11.13.3.2

Completing the test

1. Continue to test another function or end the test by changing the Test mode setting to Off.
2. Restore connections and settings to their original values if they were changed for testing
purposes.
