Sensitivity Setting
The module is supplied with the sensitivity pre-set to suit most installations and
should not need adjustment.
In locations such as tunnels, or when the module is not being used under the track
bed, then it may be desirable to adjust the detection threshold.
The sensitivity is factory set to 5, and can be adjusted from 1 to 10 (with 1 being the
most sensitive and 10 being the least sensitive).
To change the sensitivity, switch off the power to the module and hold down the
Push Button. Apply the power and continue holding the Push Button until
9 flashes
of the led are seen. At this point, release the button. You will see a long flash of five
seconds.
The led will begin flashing again. When you have reached the desired number of
flashes to set the new sensitivity, press the button. You will see a long flash of five
seconds and then 10 rapid flashes. The programming is then complete and the
module will restart. If you make a mistake programming, simply repeat the process.
Performing a factory reset will reset the sensitivity setting back to 5.
