1. Problem: Sensor / LOI mapping. The user is unsure about which sensors are mapped to which
locations. This can happen if several wire tags fall off during the installation of the fibers.
a. Identify the unknown fibers at their respective LOIs.
b. Apply an indirect heat source to the vicinity of the LOI. Heat guns are recommended for the
task but should never be directly applied to the fiber or the sensing tip. Heat the adjacent
area.
c. Return the BriteSpot® Plus conversion module and identify which unknown sensor has shown
an increase in temperature due to the application of heat.
d. Alternatively, apply a heat source sequentially to each fixture and look for a change in
measured temperature.
e. Repeat the process above until all fibers have been properly identified and marked.
2. Problem: BriteSpot indicator LEDs remain red (optical signal too low)
a. Determine if the problem is related to the fiber-optic probe or the optical connection port by
moving the probe in question to another port that has been determined to work. If the probe
functions in the test port, then the original optical connection port is likely the problem.
b. Optical port related problem. Attempt to blow any contaminants off the surface of the LED
inside the port with clean compressed air.
Do not use unfiltered, non-instrumentation
type compressed air. Re-insert the fiber into the connector and allow 30 seconds to stabilize.
Proceed to next step if BriteSpot indicator LED remains red.
c. Probe Related Problems
i. Trim ~3mm (¼”) from the end of the fiber. Re-insert the fiber into the connector and allow
30 seconds to stabilize. Proceed to next step if BriteSpot indicator LED remains red.
ii. Replace the probe.
