The sensor must be used together with
The VT594 Water Leak Sensor is designed for integration with Building Management Systems (BMS) to provide continuous monitoring for water leaks. It works in conjunction with the WLC / Water leak cable (ordered separately) to detect the presence of moisture when water comes into contact with the cable. By placing the detection cable near or along potential flood sources, such as pipes, HVAC units, or server rooms, entire areas can be effectively monitored for leaks.

Used for
The VT594 Water Leak Sensor is used for:
Leak or Flood Detection: Monitoring areas prone to water leaks, such as pipes, HVAC units, and server rooms, to detect moisture before damage occurs.
Building Management Systems (BMS) Integration: Seamlessly integrates with BMS to provide real-time alerts and continuous monitoring of potential flood sources.
Critical Infrastructure Protection: Ideal for protecting IT equipment, server rooms, and sensitive areas from water damage by ensuring early leak detection.
Comprehensive Area Monitoring: By placing the WLC Water Leak Cable around vulnerable spots, large areas can be monitored for moisture, enabling proactive maintenance.

Connect the "VT594 / Water leak sensor" to any BMS unit dry contact and 12-24V input, Gnd.
Connect the "Terminal cable" to the VT594 sensor.
Connect "WLC / Water detection cable" to "Terminal cable".
Connect any additional "WLC / Water detection cables" to each other as shown in the picture above to make a chain connection.
Wire the WLC rope around or under potentially leaking objects around the perimeter or under the raised floors.
Put a protective cap on the connector of the last WLC cable in a chain.
The sensor is ready to use.
How to test the sensor & sensor cable
Connect the WLC cable to VT594 by terminal cable. Connect VT594 to dry contact, voltage and ground points of the BMS system. Make sure that the WLC cable is straight or not contacting itself, or any conducting material. The sensor should appear in the BMS system as “Normal” (if the behavior is set to “Normal”), which means that there’s no presence of liquid (the two yellow wires along the WLC cable are not cables shorted).
Take a rag and wet it a little. Touch the rag to both yellow wires on the WLC cable. This should shorten the contact. The VT594 sensor should change the state to “Alarm”.
Dry the cable carefully with a dry cloth.

Schematics / Sensitivity adjustment
You can change the a resistor using the following schemes.
For example, if your room has very high humidity and the cable is in an alarm state without the spilled liquid being present, you can change R10 to 270k. This should lower the sensitivity level.

Troubleshooting
The following table describes potential problems and their possible causes. It also describes checks you can perform or possible solutions for each. After referring to this table, if you cannot resolve the problem, contact your local Vutlan sales representative for assistance.
Potential Problem | Possible Cause | Possible Solution |
|---|---|---|
The data being displayed is inaccurate or not what you expect. | Incorrect setup values. | Check that You use the correct f(x) formula |
Incorrect voltage inputs. | Check power meter voltage input terminals to verify that adequate voltage is present | |
The power meter is wired improperly. | Check that all wires are connected correctly and that they are energized. See “Wiring Diagrams” of the device. | |
The sensor does not appear in the Vutlan monitoring interface | Communication lines are improperly connected. | Check the 6P4C RJ11 communication cable. |
The communication cable is inserted into the wrong port. | 6P4C RJ11 communication cable must be inserted into the analog port of the Vutlan monitoring system. | |
The sensor is always in alarm state. | The cable touches itself. | The cable can not touch itself. It needs to be straightened. Please check if the cable is bent anywhere. |
The cable is twisted or pressed down too much. | Do not twist or press down the cable too much. This may lead to deformation. The cable has two sensing wires, these wires can not touch each other. | |
The cable is located on a conductive surface. | Do not put the cable on a conductive surface. | |
The cable is damaged | Check the continuity of the cables with a multimeter. Let’s call each wire A and B: If the cable is not damaged, you should get the following results
If the cable is damaged, you will get:
