Troubleshooting (Continued)
Note 1: While in hiccup mode, the rectifier will attempt to restart every 10 seconds for a maximum of 3
times.
Note 2: Refer to Section 5, LVD board Removal for removal details. Note that the power system will
continue to power the load while the LVD board is out of the system; however, there will be no
possibility of battery backup until the LVD board is replaced.
Checking for Defective VT-Probes
1. Disconnect the first probe from its RJ-45 terminal block.
2. Run the CLE function. If the system controller illuminates its LED in green color, the probe is defective. Alternatively,
the number of registered probes may be known from the terminal interface (TI) by running the Number of
Temperatures present command, see Appendix B. If the registered number of probes is equal to the total number
of probes connected, remember you've removed a probe, so the total number should be one less than that during
installation, and then the first probe is defective. Replace the probe with a different probe and follow the above
procedure to ensure it is operational.
3. If the system controller LED remains green or the number of registered probes is still incorrect, replace the first
probe and remove the second probe and repeat Step 2. Continue this procedure until the defective probe has been
found.
