Function and purpose
The sensor detects water by increasing capacitance on two metal poles. The detector is encapsulated in plastic housing. Due to the low applied voltages and the applied leakage detection principle, it does not rust over time.

Installation
Installing the sensor case | Steps |
---|---|
Cut off the ledge at the bottom of the case. The ledge at the bottom of the case is used for installation inside IT racks. | |
The sensor can be installed using a screw or a sticker | |
Installing the detector | Steps |
---|---|
A: For non-conductive surfaces. B: For conductive surfaces. C: For liquid level detection. D: For installing on to vertical surfaces for level detection. | |
The detector can be installed onto a surface using a screw or a sticker. The detector has a hole in the middle for a screw to fit it. | |
Connecting the sensor
The end poles of the sensor should not touch a conductive surface.
Connect the "VT593 / Spot leak sensor" to the monitoring unit into any available analog port. The connection is plug-an-play. Use RJ11/12 6p4c to RJ11/12 6p4c cable.
Connect the "SLD / Spot leak detector" to the "VT593 / Spot leak sensor".

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:

Cable pinouts
The sensor uses a standard Vutlan analog sensor cable (RJ11/RJ12 6P4C to RJ11/RJ12 6P4C) for connecting to the monitoring unit. You can find further instructions in the Analog sensors connection article
The detector uses two wires. It has black and red wire. Plus or minus is irrelevant.
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 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. |
Frequently asked questions
Question | Answer |
---|---|
Can I connect “SLD / Spot leak detector” to a 3rd party alarm system without “VT593 / Water spot sensor? | Yes, you can. But it depends on the alarm inputs charachteruistics of a 3rd party device. |
Can I connect “WSD / water spot detector” to an dry contact inputs of Vutlan monitoring systems? | No, you can not. The resistance is high and this results in highly unreliable operation. |
