Np Sensor Tester Wiring Diagram
Lead of the tester diagram viewed from fitting side of 2 water proof connector turn the ignition switch on.
Np sensor tester wiring diagram. Referring to the npn wiring diagram above note that the sensor supply voltage and the high side of the load are connected to the same point and are therefore at the same voltage. Looking for what wire is what on the speed sensor plug. You will notice that the load appears between the v brown and switching wire black. In hazardous or explosive atmospheres special care must be exercised to determine the classification of the hazard and to employ components with an approved.
When connecting to the plc the plc input acts as the load. The v brown will be attached to the common input and the switching wire black will be attached to the input number. Ig on engine off turn on the main switch. This is a three wiring sensor one wire is used for sensor power the other two go directly into the computer for sensing purposes.
Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor. Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically. The following is a wiring diagram of an open collector npn sensor. Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor.
Normal conditions s terminal voltage. 7 6 1v connect the lead of the tester. Any help would be much appreciated. It was cut off so i don t know what one is 5 sense and ground and i need to splice it into my swap harness so no wire colors will match up.
Oh it came off a 2000 2 5l tj if that helps. Check voltage of the s terminal shown in fig.
