One or both of the
QS871A shunt inputs is
open-circuit.
1. Verify that the
respective shunt has its green
and yellow wire connections
attached used for the current
measurements.
2. Verify the shunt connection to
the QS871A is good by verifying
the green and yellow wire
connections from the shunt
follows through to the 10-pin
connector at the respective
QS871A.
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
will 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.
