4.2 Rectifier High Voltage Shutdown and Lockout Restart
Procedure
1. Turn AC power to the V200 Retrofit OFF or remove the rectifier from the V200 Mounting Frame, wait 30 seconds or more;
then turn AC power to the V200 Retrofit ON or re-insert the rectifier. Refer to “Replacing a Rectifier” on page 24 for a
rectifier removal procedure.
5 Troubleshooting and Repair
5.1 Troubleshooting
5.1.1 Rectifier Current Sharing Imbalance
When multiple Rectifiers are operating in parallel and the current sharing imbalance among them is greater than 3%, check to verify
the Rectifier is properly seated in the Mounting Frame. (Refer to “Replacing a Rectifier” on page 24 for procedure to remove and
reinstall a Rectifier.)
If the current sharing imbalance still persists following the verification suggested above, replace the rectifier exhibiting the current
imbalance.
5.1.2 Rectifier Fault Symptoms and Troubleshooting
The Power System controller (MCA) provides the same fault indications for the Retrofit as for the original V200E50 PCUs. Refer to
your Power System documentation for details.
NOTE! The system MCA identifies each V200 Retrofit as one PCU. If a PCU fault condition is indicated, observe the local
indicators on the Rectifiers in that Retrofit to localize the fault to one Rectifier.
