Installation Guide
Preparation Steps
Installing the TR T4U3820 49-155-003 LP38A is simple with proper preparation. First, gather the necessary tools: a screwdriver, wrench, and cable cutter. Before installation, inspect the transducer and the included T4U3820 magnet for any damage during transportation.
Check that the model and specifications match your application requirements, especially the measuring length and output type. Prepare the mounting surface and ensure it is flat and stable. This prevents vibration during operation, which could affect measurement accuracy.
Also, confirm the power supply meets the 24 VDC ±10% requirement. Prepare the signal cable according to the output type, ensuring it is long enough for the installation distance.
Mounting the Transducer
The TR T4U3820 49-155-003 LP38A features a profile housing for easy mounting. Use the appropriate screws to fix the transducer to the mounting surface. Ensure the mounting is firm and free of looseness to avoid vibration.
There are no strict restrictions on the mounting position. You can install it horizontally or vertically based on your application needs. Ensure the measuring body aligns with the moving component to be measured, maintaining a consistent distance for accurate detection.
Next, attach the T4U3820 open ring magnet to the moving part of the application. Ensure the magnet is positioned correctly relative to the transducer’s measuring system. The recommended distance between the magnet and the measuring system is specified in the installation manual.
Wiring and Calibration
After mounting, connect the power supply and signal cables. Follow the voltage requirements when connecting the power cable. Never reverse the positive and negative poles—this can damage the transducer’s internal components.
Connect the signal cable to the corresponding interface of the receiving device (PLC, counter, or display). Ensure the cable is secured tightly to prevent poor contact. For analog outputs, check the load resistance to ensure compatibility with the receiving device.
Once wiring is complete, power on the transducer and receiving device. Use the set-inputs to adjust and calibrate the transducer. Follow the installation manual to set the measuring range and output parameters. Perform a test by moving the magnet along the measuring length to verify accurate signal output.
