Quick Wi-Fi setup

Connect the sensor to your local network

Power the sensor

Apply 5–32 VDC. A 24 VDC industrial power supply is recommended. During startup, the sensor broadcasts a temporary Wi-Fi access point.

Connect to the access point

Use a phone, tablet, or computer to connect to the sensor Wi-Fi network.

SSID example:
LACC001/000010

Password:
lumos1111

Open the setup page

After connecting to the sensor access point, open a web browser and visit:

http://192.168.1.100

Enter the facility Wi-Fi credentials, save the settings, and restart the sensor.

Factory access-point information

Installation Requirement

Proper mounting is essential for reliable vibration measurement and long-term sensor protection.

⚠ Electrical Isolation Required

An electrical insulation plate or insulating paper must be installed between the vibration sensor and the machine surface.

This insulation prevents electrical conduction between the machine frame and the sensor enclosure, helping protect the electronics while ensuring stable and reliable vibration measurements.

Installation Instructions

Clean the machine mounting surface.
Place an insulating plate or insulating paper on the mounting location.
Position the Lumos vibration sensor on top of the insulating material.
Secure the sensor using the recommended mounting screws.
Verify that the sensor body does not make direct electrical contact with the machine surface.
Confirm that the sensor is firmly mounted without excessive movement.

Important

Direct metal-to-metal contact between the sensor housing and the machine may create an unwanted electrical path that can affect sensor reliability. Always install an electrical insulation plate or insulating paper between the sensor and the machine surface.
