This video contains detailed instructions on the wiring of the Pyxis CR 300 LPR corrosion sensor to a wall cam w 600 controller when you receive your CR 300 LPR corrosion sensor you will observe that two calibration caps are provided one for mild steel and one for copper you will also receive a set of seven to eight pin conversion adapters which can be utilized for connection to the wireless or USB adapter that enables you to use the U Pyxis app the CR 300 corrosion sensor offers both general and localized corrosion output as a standard 420 milliamp signal as well as an rs-485 Modbus prior to any wiring please be sure to power down your W 600 controller unit for wiring to the W 600 you'll be using two of the 420 milliamp or analog output signals available from the CR 300 to properly terminate the 420 milliamp signals from the CR 300 to the W 600 you will be landing your input signals to terminal block to the red wire is 24 volt power and should be terminated to the input slot 1 the brown wire is power ground and should be terminated to input slot to the gray wire is 420 milliamp per turn and should be terminated to slot 3 the white wire is the general corrosion input analog signal and should be terminated to input slot for the pink wire is the pitting corrosion input analog signal and should be terminated to input slot 10 finally the green wire should be terminated as earth ground again that's red - one brown - - gray - three white - for pink 210 and green - ground after wiring to terminal block - you'll need to set up and connect the Pyxis CR 300 unscrew the attachment cap place the gaskets under the threaded electrode prongs then attach the LPR corrosion electrodes then terminate the 8-pin wire connection to the top of the probe in order to simulate a set corrosion rate after configuration you may place either the steel or copper calibration check caps that are provided with a CR 300 after fully connecting to the W 600 you may power up the unit and prepare the probe for configuration the CR 300 probe will require setup using the you Pyxis application for other smartphone or desktop either the Pyxis wireless or USB adapters can be used and one will be provided with the CR 300 unit the CR 300 can be configured for five electrode metallurgies including mild steel copper brass 304 stainless and aluminum CR 300 electrode metallurgy selection and the you Pyxis app will preset the 420 milliamp span for both pitting and general corrosion detection limits in Mills per year interval readings should be set for greater than three minutes in you Pyxis in order for pitting corrosion to register on your controller once the probe has been set up via you Pyxis and properly wired you may proceed to configuring your w 600 unit as normal.
