　　Effort 2 - 4 h

　　Replacement means exchange of components as part of the maintenance schedule or as a consequence of performed visual inspection or performance checks.

　　The procedures to replace components are described in chapter 7, Checking control components, page 81 or in chapter 10, Replacing power and cooling components, page 133. The corresponding sections are depicted in the following table.

　　For replacement tasks without a description of the replacement procedure in this service manual, always shut-down the PCS6000 according to “PCS6000 Lockout/tagout procedure”, 3BHS600000 E22 Switch off the corresponding MCB (see electrical diagram) before replacing the component. Restart the PCS6000 according to section 5.4, Start-up after maintenance or troubleshooting, page 70.

　　DC-link performance check

　　Effort 0 - 2 h

　　The DC-link charging for performance check is performed via the test module of the converter HMI.

　　IMPORTANT! The measurement results are compared to the nominal values in the “PCS6000 Preventive maintenance report”, 3BHS600000 E84.

　　The deviation of the measured values from the nominal values is grouped in 3 categories:

　　– OK: The measurement result is in the expected range.

　　– Monitor: The measurement result is near the limit.

　　The respective component is still OK, but it makes sense to compare previous and future measurements to monitor a trend, as well as to compare similar measurements taken with the same instrument.

　　– Action: The respective component might be faulty and should be replaced.

　　Procedure:

　　1. Shut down the PCS6000 according to the “PCS6000 Lockout/tagout procedure”, 3BHS600000 E22.

　　2. Close all doors.

　　3. Open DC-link grounding switch.

　　4. Charge the DC link up to +/-500V.

　　5. Record the discharging time from +/-500 to +/-200V.

　　6. Record the discharge time in the Preventive Maintenance Report.

　　7. If the converter is a 2CL system, repeat the test with the second conversation line.

　　8. After completing all work, restart the PCS6000 according to section 5.4, Start-up after maintenance or troubleshooting, page 70.

　　DC-link component check

　　Effort 4 - 8 h

　　The DC-link component check has to be done as described below, if the procedure in section 4.4.5, DC-link performance check, page 56 shows a deviation from the nominal value more than 10%.

　　IMPORTANT! A standard multimeter with capacitance measuring function (up to 10 mF) is required to perform these measurements.

　　The measurement results are compared to the nominal values in the Preventive Maintenance Report. The deviation of the measured values from the nominal values is grouped in 3 categories:

　　– OK: The measurement result is in the expected range.

　　– Monitor: The measurement result is near the limit.

　　The respective component is still OK, but it makes sense to compare previous and future measurements to monitor a trend, as well as to compare similar measurements taken with the same instrument.

　　– Action: The respective component might be faulty and should be replaced.

　　Procedure:

　　1. Shut down the PCS6000 according to the “PCS6000 Lockout/tagout procedure”, 3BHS600000 E22.

　　2. Double check that the DC-link is grounded (ground switch).

　　3. Remove reinforcement plates and the ASM10 (Auxiliary Supply Module).

　　4. Disconnect the three sets of measurement the wires (1, 2 and 3) which connect the DClink capacitors (C701…C703) to the converter.

　　5. Record the serial number of each capacitor in the Preventive Maintenance Report.

　　6. Measure the capacitance of Grid side Power Module Capacitors (see electrical circuit diagram POMxx).

　　7. Measure the capacitance of Generator side Power Module Capacitors (see electrical circuit diagram POMxx).

　　8. Reconnect the wires/busbars from the converter with the marked tightening torque (see separate sticker on the capacitor) to the capacitors

　　NOTE – If the tightening torque is not specified on the capacitor, use tightening torque defined under section 10.4.1, Correct tightening torques of bolted connections, page 135.

　　9. After completing all work, restart the PCS6000 according to section 5.4, Start-up after maintenance or troubleshooting, page 70.

　　Filter components performance check

　　IMPORTANT! A standard multimeter with capacitance measuring function (up to 10 mF) is required to perform these measurements.

　　The measurement results are compared to the nominal values in the Preventive Maintenance Report. The deviation of the measured values from the nominal values is grouped in 3 categories:

　　– OK: The measurement result is in the expected range.

　　– Monitor: The measurement result is near the limit.

　　The respective component is still OK, but it makes sense to compare previous and future measurements to monitor a trend, as well as to compare similar measurements taken with the same instrument.

　　– Action: The respective component might be faulty and should be replaced.

　　The filter components performance check comprises the following 3 parts:

　　– Grid side filter components performance check (see section 4.4.7.1, Grid side filter components performance check, page 59)

　　– Neutral point performance check (see section 4.4.7.2, Neutral point performance check, page 61)

　　2. Double check that the DC-link is grounded (ground switch) and the grid side is grounded (grounding kit).

　　3. Disconnect the PE wire to -R544:2 in cabinet +A12. (see electrical circuit diagram HFMxx).
