There are sizes: Short and Long. Use a 9/32” twist drill bit to drill a hole between the rails. We recommend you remove at least one of the ties so that you are drilling through the underlayment or roadbed and not through the plastic rails. October 2023...
INSTALLATION SUMMARY Plug the Sensor cable into the Nano Controller on the right side FIRST. This cable is a 5-Pin connector. This plug will NOT fit on the left side 4-pin socket. In this way you cannot make a mistake. The plug will fit only one way – smooth side up. Plug the sensor into the 5-wire connector BEFORE turning the power on –...

On the board is a blue indicator LED. This will flash four times when power is first turned on and thereafter will light when the detector is triggered. (INVERT mode will have the light ON when not triggered and OFF when triggered) NOTE: If the Blue LED doesn’t not Flash four times rapidly at power on, no amount of pressing the select button will help.

The wire length is about 9”. This is the MAX length where the sensor will work properly. The signal in the wire is relatively low power (weak) so it can be upset by electrical noise from nearby wires. Try to keep the sensor wires away from other wires and do not cross over wires is possible.

The detector can be also set to detect an adjustable Long Range from 5mm up to 150mm. In this case, the sensor does not have to be mounted under the track. You can use it anywhere. Anything within the range you set beginning at 5mm - will trigger the detector.

To use the LONG RANGE you will use the Auto-Calibrate mode that you may be familiar with in our other Precision Detectors. AUTO-CALIBRATE for LONG RANGE 1. Press and hold the select button on the sensor. The blue light will turn on momentarily and then go off. KEEP holding until the light comes back on.

NOTE: It is BEST to set the timeout adjustment to zero so that the LED will go out immediately after you move the rail car. This makes confirming the correct operations much easier. If you are using the PRECISION DETECTOR™ with our MTT Signal Controller or MTT Relays you will most likely want to leave the setting to 5 seconds and let the Signal Controller manage the signal light timing.
INSTALLATION and TESTING Connect the RED power wires to your 12VDC power source. There is no polarity required. With power ON you can place your hand in front of the sensor and the blue LED should light and go off when you move away. The Yellow Signal (SIGNAL) wire can now be connected to the controller device of your choice.

An INVERTED SIGNAL simply means that the NANO PRECISION DETECTOR™ will send an ON signal when the sensor is OFF, and visa versa. You can tell this is the case if the blue LED is always on but turns OFF when you place your hand in front of the sensor.

ELECTRONICS AND STATIC ELECTRICITY The MTT PRECISION DETECTOR™ - Trackside circuit board and components are exposed when the cover is off. Static electricity can cause component failure. Scuffing along a carpet and then touching one of the component connectors can cause a static spark.
