Meridian Companion Installation and Maintenance Guide
– The distance between the RPI and the Base Station is in
accordance with the values in Table 4 in the chapter “Installing the
hardware.” If not, power the Base Station with a plug-top power
supply, move the RPI closer to the Base Station, or use two RPI
power pairs if you were using only one.
– There is a faulty Base Station or RPI.
3. Verify that the RPI is connected to a working power source and that all
connections to the RPI (power cord, jumper lead, input and output, etc.)
are correct and secured.
4. Check that the UPS fuse is live.
a. Remove the RPI cover.
b. Unplug the RPI from the AC outlet.
c. Remove the fuse cover.
d. Visually inspect the fuse to see if it needs replacement.
e. Replace the fuse if necessary.
5. Make sure the TCM device wiring has been correctly installed.
6. If none of the Base Stations connected to the RPI (or to one of its power
supply units) are functioning correctly, replace the RPI (or power supply
unit).
Note: The left power supply unit provides power through output
connectors OBIX1 to OBIX8, and the right power supply unit
provides power through OBIX9 to OBIX16.
7. If only one or a few of the Base Stations seem faulty, try putting the Base
Station on another RPI power pair connector. If you continue to have
difficulty, see “Troubleshooting a Base Station” on page 169.
