WLC / Water leak cable

(recommended)

(ordered separately)

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

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 the Analog sensors connection

...

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.

Schematics / Sensitivity adjustment

You can change the R10 resistor using the following schemes.

...

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

  1. A-A: there’s a continuity. (I thinks it’s good)

  2. A-B: there’s a continuity. (I think there shouldn’t be any)

  3. B-B: there’s a continuity

If the cable is damaged, you will get:

  1. A-B: there’s a continuity. There should not be a continuity. The wires cross each other somewhere.

or

  1. B-B or A-A: no continuity (the wire is damaged).
