CWP_VP overcurrent or overpower protection
Possible Cause
1. The PHV voltage load causes the abnormal voltage output.
2. The power circuit of the PHV board fails.
Resolve Path
Cross-test the probe and the probe groove. If the probe and the probe board are normal, apply to
replace the main unit assembly.
Solution
1. Restart the machine, and check whether the fault is rectified.
2. Check whether the fault exists on a specific probe groove. If yes, clean the probe groove. If the
fault persists after cleaning, replace the probe board assembly. For details, refer to 7.9.2
Disassembly and Assembly.
3. Check whether the fault exists on a specific probe. If yes, replace the probe.
4. If the fault appears on all probes, cross-test or replace the main board. For details, refer to
7.13.2
Disassembly and Assembly.
