Component Troubleshooting
Rectifying Rectifier Faults
A rectifier is damaged if either of the following conditions is not met:
l When the rectifier does not communicate with the SMU, the Run indicator on the rectifier is steady on, the Fault indicator is off, and the AC input voltage is around 220 V. The rectifier output is normal.
l The SMU can perform equalized charging, float charging, and current limiting control for the rectifier when the communication cable to the rectifier is correctly connected and communication is established between the rectifier and the SMU.
Rectifying SMU Faults
The common SMU faults are as follows:
l The SMU is faulty, for example, when one of the following occurs: SMU breakdown, startup failure, LCD failure, and keyboard operation failure.
l The SMU does not generate an alarm when a fault occurs.
l The SMU generates an alarm (false alarm) when the system runs properly.
l Communication is interrupted when the SMU monitors the subordinate equipment.
l The SMU fails to control or monitor all the modules when these modules run properly and communications cables are connected properly.
l The SMU fails to monitor and control AC distribution and DC distribution when AC and DC power is distributed normally and communications cables are connected properly.
l Parameters cannot be set or operating information cannot be viewed on the SMU.
