9.11 Checking for Hot Bearing
To generate a test train to check for hot bearings:
STC recommends that you use the calibrated heat source (2100-810NG) only when
the outside (ambient) temperature is above 0°F (-18°C) and below 90°F (32°C).
If you
must use it at other times, do so only when the needle is centered on the front of the
temperature meter. If the needle isn't stabilized within

2 degrees of set point, the heat
source isn't operating properly.
1 Ready the calibrated heat source.
After powering it up, let the heat source sit in the shade and out of the wind for at least
8 minutes to stabilize. The heat source has reached operating temperature and
stabilized when the temperature meter needle remains centered.
2 Stroke both gating transducers four times with a metal wrench, starting with TO1.
3 Stroke TO1 one more time with a metal wrench.
4 With the power cord to the front of the scanner, place the calibrated heat source on the
bearing scanner that is on the rail with the gating transducers.
5 Stroke TO2 with a metal wrench.
You should hear the real-time defect message from the radio.
6 Wait for the system to time out, which normally takes about 10 seconds.
You should hear an end-of-train message with one Hotbox alarm.
7 Listen to be sure that the Hotbox alarm was announced on the correct side and on axle
five.
If you don't hear anything, no alarm-level heat was recorded. No measurable heat
from a bearing scanner may be due to loose connections, a scanner not being
connected on the Scanner Interface board, a defective shutter motor in the scanner, or
a damaged scanner.
8 If you don't hear a Hotbox alarm being announced, fix this problem before proceeding.
