GREYSTONE WLDC Series Conductivity Cable Water Detector

Product Information

Specifications:

Available with one or two relay outputs
Designed to detect water or conductive liquids
Signals alarms for water detection, power loss, or internal failure
IP65 rated enclosure
Various lengths of cable are available
Optional leader cable available
Height adjustable mounting legs with 5 preset heights
LED provides visual status indication

Product Usage Instructions

Before Installation:

Secure the sensor by applying a silicone adhesive to the mounting feet or using screws provided.
If the device was ordered with a leader cable, disconnect the conductivity cable for installation by twisting the connector counter-clockwise and pulling it apart.
To adjust leg height, remove the screws and pull/push the legs to the desired height. Re-insert screws and tighten.
Open the cover by pulling slightly on the latch on the enclosure and at the same time pulling up on the cover.
Secure the cable in place using the self-adhesive cable clips provided. Start by adhering clips at each end of the cable first. Secure the cable approximately every 1.5 m (5′).
Lay the cable in a straight line or in a serpentine configuration, being careful not to kink the cable.
Connections:
Make all connections in accordance with national and local codes.
Use 14-22 AWG shielded wire and do not locate the device wires in the same conduit with wiring used to supply inductive loads such as motors.
Connect 24 Vac/Vdc to PWR & COM terminals. Ensure all connections are made before applying power to prevent electrical shock or equipment damage.
Do not exceed the device contact ratings. The relays are Form C type with both a normally open (NO) and a normally closed (NC) contact.
Each relay output is independent and isolated from the other. The relays COMs are not connected to the device COM.
Operation:
For models with two relays, set the operation jumper.
- M0 position: Relay 1 & 2 activate on water detection and trouble.
- M1 position: Relay 1 activates on water detection and Relay 2 activates on trouble.

FAQ:

Q: What is the IP rating of the enclosure?
A: The enclosure has an IP65 rating, indicating it is protected against dust and low-pressure water jets from any direction.
Q: Can I use the sensor to detect liquids other than water?
A: Yes, the sensor is designed to detect conductive liquids, so it can be used to detect liquids other than water as long as they are conductive.
Q: Can I adjust the height of the mounting legs?
A: Yes, the mounting legs have five preset heights that can be adjusted by removing the screws and pulling/pushing the legs to the desired height.

INTRODUCTION

The conductivity cable water detector is used to detect the presence of water or conductive liquids. It is available with either one or two relay outputs and is designed to signal alarms if one or more of three conditions are met: water is detected, power is lost to the unit, or there is an internal failure.

The conductivity cable water detector is housed in an IP65-rated enclosure with various lengths of cable available. An optional leader cable is also available in various lengths. It features height-adjustable mounting legs that include 5 preset mounting heights. An LED provides a visual status indication.

BEFORE INSTALLATION

Read these instructions carefully before installing and commissioning the water detector. Failure to follow these instructions may result in product damage.
Do not use in an explosive or hazardous environment, with combustible or flammable gases, as a safety or emergency stop device, or in any other application where the failure of the product could result in personal injury.
Take electrostatic discharge precautions during installation and do not exceed the device ratings.

INSTALLATION

Secure by applying a silicone adhesive to the mounting feet and placing the sensor in the area to be protected. For more permanent installations, fasten the sensor using the holes provided in the mounting feet.
NOTE: If the device was ordered with a leader cable, the conductivity cable can be disconnected to assist in installation. To remove, twist the connector counter-clockwise and pull it apart.
The legs have five pre-set heights set by the holes in the leg. To adjust leg height, remove the screws. Pull/push the legs to the height desired, and re-insert screws and tighten.
Open the cover by pulling slightly on the latch on the enclosure and at the same time pulling up on the cover.
Once laid in place, secure using the self-adhesive cable clips provided. For best results adhere clips at each end of the cable first. Clips are provided to secure cable approximately every 1.5 m (5’). $GREYSTONE-WLDC-Series-Conductivity-Cable-Water-Detector-fig- $4$$
The cable may be laid in a straight line or in a serpentine configuration. Be careful not to kink the cable.
Make all connections in accordance with national and local codes. Use 14-22 AWG shielded wire and do not locate the device wires in the same conduit with wiring used to supply inductive loads such as motors. The device is reverse voltage protected and will not operate if connected backward.
To prevent electrical shock or equipment damage make all connections before applying power. Connect 24 Vac/Vdc to PWR & COM terminals.
NOTE: Use caution when wiring multiple devices or when grounding the secondary of a transformer to ensure that the circuit ground point is the same on all devices and the controller.
Do not exceed the device contact ratings. The relays are Form C type with both a normally open (NO) and a normally closed (NC) contact. Relay terminals are designated NO, CM*, and NC.
NOTE: Each relay output is independent and isolated from the other and the relay’s COMs are not connected to the device COM.
Only for models with 2 relays, set the operation jumper. M0 position = Relay 1 & 2 Activate on water detection and trouble M1 position = Relay 1 activates on water detection and Relay 2 on trouble See Operation section for full details.
NOTE: All additional jumpers are factory set. Do not change position. Changing the jumper position will cause the device to be in a constant alarm state.
Use the provided security screws to secure the cover.

OPERATION

When the detector is powered on, it will monitor for the liquid detection channels. If a conductive liquid comes in contact with the conductive cable the detector will trigger the relay(s) to indicate liquid is present.
The conductive cable sensor includes a trouble check feature that can be used to verify the cable is not damaged or connected improperly. On the 2-relay model, the relays can be set so that both relays activate on both water detection and trouble or that relay 1 activates on water detection and relay 2 activates as trouble notification.

The relays are fail-safe, meaning when power is applied to the device the relay is powered. If power is lost to the device the relay will de-energize signaling a fault to the system.
