any any R Failed Ringer. Replace Ringer.
Note 1: While in hiccup mode:
• Rectifiers will attempt to restart every 10 seconds for a maximum of 3 times.
• Ringers will attempt to restart every 2 minutes.
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.
Note 3: LED may be RED where shown here as AMBER. Controller LED indicates the severity of the most severe active
alarm. If any active alarm is Major, the LED will be RED. If only Minor alarms are active (no Major alarms), the
LED will be AMBER. If no alarms are active, the LED will be GREEN.
Note 4: o = OFF
R, G, or A = ON (Red, Green, or Amber)
–R–, –G–, or –A– = Blinking (Red, Green, or Amber)
Grayed out cells = any LED state may be displayed. This LED does not indicate this problem.
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 A. 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, 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.
