Signal Pin 3 Blue Power 5 12V Yellow n c The waterspeed sensor can be used to measure boat speed through the water The sensor can measure the effective speed of offshore boats which may be out of the water up to 50 percent of the time 53 The sensor should be mounted on the boat s transom where the flow of water is least turbulent The left port side of the transom is preferable if it is impractical to mount it there the right side can be used Don t mount the sensor behind strakes or ribs as these disturb the water flow to the speed sensor Also make certain that the sensor will remain in the water even when the boat is on plane The sensor is generally mounted about one foot from the boat s centre line boat hull cross section poor location good locations Positioning the Sensor on the hull When setting tyre size and triggers on the dash try using 650mm and 20 pulses rev A hand held Global Positioning System can be used to check the calibration If you experience any problems contact your Pi representative 54 C dash User Guide Wheelspeed selector box mounting box peg pin lettering c scheme o i S o o o A B n o o o o o o ho 17 o o o T s Wheelspeed selector box connector pinout Wheelspeed selector box Mounting Industrial Velcro Supply voltage 6 18V Supply current 4mA Connector KPT 2E 12 10P Cannon or equivalent Connections Pin A Wheelspeed 1 sensor sig
