C.3 Gate Test
Selection of the Gate Test option opens the scanner shutters and simulates a passing train.
While in this mode, you can simulate alarms by placing a heat source on a scanner or by
opening an auxiliary alarm detector's contacts.
You can stop the gate test by pressing [Esc] . If you don't press [Esc] , the test continues until
486 axles are simulated. The firmware pauses between railcars and scans for a pressed
[Esc] . Consequently, the gate test may not terminate immediately after [Esc] is pressed. It
may need to finish the current car's axles. Pressing keys before pressing [Esc] results in the
generation of additional cars of axles before aborting. There will be one additional car of axles
for each key pressed before pressing
[Esc] .
After pressing [Y] to begin the gate test, the "Running Gate Test..." message appears followed
by a four-second pause.
C.4 1KHz Test Tone
Selection of the 1KHz Test Tone option generates a continuous one-kilohertz tone for
15 seconds. This tone is broadcast through the speaker and through the radio. Using this
option lets you verify that the speaker and radio are working properly.
C.5 Auto-Calibration
Selection of the Auto-Calibration option places the system in autocalibration mode.
The SmartScanIS self-calibrates its pyrometer interface circuitry. You need only put a
preheated calibrated heat source on a scanner and place the system in autocalibration mode.
The system then scans all pyrometer inputs until the signal from the calibrated heat source is
located. The necessary adjustments to the related interface circuitry are automatically made
while the system monitors its own progress by analyzing changes in the heat signals. Once
the procedure has been completed, autocalibration mode is disengaged and the calibration
results are displayed on your computer. For more details, see
Appendix E - Calibration of
Scanners .
