Wiring the Pyxis CR-300 to the Walchem w600 Controller
Step 1: Connect the Wires to Terminal Block 2
Step 1: Connect the Wires to Terminal Block 2
Properly terminate the 4-20 mA signals from the CR-300 to the w600. Connect the wires to Terminal Block 2 as follows:
Red wire (24V power) to Input Slot 1
Brown wire (Power Ground) to Input Slot 2
Gray wire (4-20 mA Return) to Input Slot 3
White wire (General Corrosion Input) to Input Slot 4
Pink wire (Pitting Corrosion Input) to Input Slot 10
Green wire (Earth Ground) to the ground
Step 2: Set Up and Connect the Pyxis CR-300
Step 2: Set Up and Connect the Pyxis CR-300
Unscrew the attachment cap, place the gaskets under the threaded electrode prongs, and attach the LPR corrosion electrodes. Finally, terminate the 8-pin wire connection to the top of the probe.
Configuring the CR-300 Probe and w600 Controller
Step 3: Set Up the CR-300 Probe Using the uPyxis App
Step 3: Set Up the CR-300 Probe Using the uPyxis App
The CR-300 probe requires setup using the uPyxis application on a smartphone or desktop. Connect the CR-300 to either a Pyxis wireless or USB adapter (provided with the unit). The CR-300 can be configured for five electrode metallurgies: mild steel, copper, brass, 304 stainless, and aluminum. Set interval readings to more than three minutes for pitting corrosion to register on your controller.
Step 4: Configure the Walchem w600 Controller
Step 4: Configure the Walchem w600 Controller
After the probe has been set up via the uPyxis app and properly wired, proceed to configure your Walchem w600 Controller as per the normal process.
✅ Your Pyxis CR-300 LPR Corrosion Sensor is now wired and set up with the Walchem w600 Controller.
