How to Connect the OilWear (OW) Sensor: A Step-by-Step Guide for Seamless Setup

Connecting your OW Sensor correctly is essential for accurate particle analysis and real-time oil monitoring. Follow these steps to ensure your system is powered, communicating, and ready for operation.

Sensor Connection Overview

The OW system features versatile electrical/electronic interfaces that facilitate data acquisition and operation. It includes:

Power Supply Input

Modbus RTU Interface (RS485 Communication)
Modbus TCP/IP Interface (Ethernet Communication)

Connector Details

The OW uses a 5-pin M12 male connector to streamline connections for power and Modbus RTU communication:

Pin	Function	Wire Color
2	VDC IN (Power)	White
3	GND IN (Ground)	Blue
5	D– (RS485 Data -)	Gray
4	D+ (RS485 Data +)	Black

Step-by-Step Connection

1. Power Supply
  1. Connect the 24VDC Power Supply to the sensor using the OW2-Wire_A patch cord.
  2. Ensure the correct pins (VDC IN and GND) are matched.
2. Modbus RTU (RS485 Communication)
  1. Use pins 4 (D+) and 5 (D–) for RS485 communication.
  2. Connect the OW to your control system or acquisition device.
3. TCP/IP Communication (Optional)
  1. If using Modbus TCP/IP, connect the OW2-ETH patch cord to an Ethernet port.
  2. Use the internal TCP/IP server for data acquisition.

LED Indicators for Quick Diagnostics

The OW features LED indicators to inform you of its status:

Red (Stable): Power is ON.
Orange (Stable): TCP/IP communication established.
Orange (Blinking): TCP/IP data transmission in progress.

Quick Notes:

The OW starts working automatically with default settings.
Calibration is unnecessary for oil type (except for OilHealth degradation monitoring).
Ensure all connections are sealed to IP65 standards for environmental protection.

For more advanced communication setups, refer to our Modbus Integration Guide.
With these steps, your OW sensor will deliver reliable oil cleanliness data, fault detection, and particle analysis seamlessly.
