How it Works
Optical sensor on inside surface of windshield using beams of infrared light.
Activation switch sets to unit default sensitivity. Unit automatically controls wipers from full off, through intermittent, slow, and high speed operation.
Max windshield thickness: 12 mm -- Almost all cars and light trucks, many motor homes are compatible with the Rain Tracker RT-50A
The sensitivity of the Rain Tracker RT-50A can be adjusted using the trimmer potentiometer located on the sensor. For more sensitivity adjust the potentiometer clockwise. For less sensitivity, adjust the potentiometer counter-clockwise.
Nominal 12V operation. 15A current capacity on interface relays.
Nominal current drain of RT-50 itself with sensor on standard solar-control glass is 20 mA.
The module (with sensor) requires a DC supply voltage between 10 and 16 volts, measured at the supply input.
System will withstand 25V for one minute.
RT-50A System protected against reverse polarity to –25V.
Drawings for hot and ground side switching wiper systems included. Drawings for many other wiper systems available on www.raintracker.com.
Sensor: 1.75" X 1.75" X .75" / 1 oz.
Interface module: 4.45" X 2.45" X 1.15" / 4 oz.
System (with sensor) operates in ambient air temperatures between –40 C and +85 C. Sensing of rain not required below –15 C.
Nominal system power up time: 2.5 seconds.
System does not wipe on vehicle power up.
System gives single wiper on activation.
Activation switch input:
Connect to supply for operation at default sensitivity. (A diode from drop is permissible.)
Open circuit to activation switch input
for system deactivation.
