VT591 / Water leak rope sensor (Legacy with WDC)

Function and purpose

Notice on 6th June 2019: The product has been altered. RJ9 4P2C connected is now used instead of 2P Power Terminal.

The sensor must be used together with

(ordered separately)

When water is in contact with the detection cable sensor indicates the emergence of moisture. "WDC / Water detection rope" and "WLC / Water leakage cable" are ordered separately! The whole area can be effectively monitored by placing the cable near or along with possible flood sources.

Connecting WDC / Water detection rope

Connect the WDC rope sensor to the VT591 leak sensor.
Wire the WDC rope around or under potentially leaking objects around the perimeter or under raised floors.
Connect the sensor to the monitoring unit. The connection is plug-an-play.
The sensor is ready to use.

Connecting WLC / Water leak cable

The cable can not touch itself. It needs to be straightened.

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.

Do not put the cable on a conductive surface.

You can cut the cable, but you need to isolate the ends so that they do not touch each other. And do not loop the cable.

Connect the "VT591 / Water leak sensor" to the monitoring unit. The connection is plug-an-play.
Connect "VTC / Terminal cable" to the VT591 sensor.
Connect "WLC / Water detection cable" to "VTC / 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 raised floors.
Put a protective cap on the connector of the last WLC cable in a chain.
The sensor is ready to use.

Analog sensor connection

Connecting analog sensors

Connect the analog sensor by a supplied RJ-11 (6P4C) cable to any analog port "A1 .. A8" or "Sensor" port. The determination of the sensor type and connection will occur automatically.

If strong electromagnetic interference is present, we recommend using a 3-pair cable CAN FTP for sensor connection!

Extending the number of analog sensors

Using CAN extension "VT408 / Sensor extension unit" it is possible to increase the number of analog sensors connected to the monitoring unit up to 80 sensors.

Chain connection of analog sensors

This procedure applies to the following sensors, which are supported by the appliance and are connected to the analog ports:

Analog sensors	Daisy chain
VT500 / Temperature sensor	□
VT501 / Outdoor temperature sensor	□
VT510 / Humidity sensor	□
VT520 / AC Voltage detector	□
VT520DIN / AC Voltmeter	□
VT530 / Access sensor	■
VT540 / Vibration sensor	□
VT550/ Wind speed meter	□
VT560 / Smoke sensor	■
VT570 / PIR sensor	□
VT572 / Radar motion sensor	□
VT591 / Cable leak sensor	□
VT593 / Spot leak sensor	□

VT530 and VT560 are the only analog sensors that allow non-addressable chain connection. All the sensors in one chain are seen by the system as one sensor. One chain can have up to 10 sensors. Example of such connection:

Installation examples

Please find installation examples in our article "Water leakage detection using cable sensor and spot sensor".

Cable pinouts

The sensor uses a standard Vutlan analog sensor cable(RJ11/RJ12 to RJ11/RJ12) for connecting to the monitoring unit. You can find further instructions at: Analog sensors connection

Technical support

The device does not contain any user-serviceable parts. If the power meter requires service, contact your local sales representative. Do not open the device. Opening the device voids the warranty.

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 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.
