Greystone Energy Systems WD-100 Series User manual

Introduction
This water detector is a microchip-based device that uses conductivity
cable to detect the presence of water or conductive liquids at any point
along the cable. It is powered by an AC or DC source, 14 - 30 volts. It
features Normally Open and Normally Closed (Form C) relay contacts
rated at 4A @ 250 VAC/30 VDC for connection to a monitoring system, or
direct control of another device. The water detector is designed to signal
an alarm if one or more of three conditions are met: water is detected,
power is lost to the unit, or if there is an internal failure.
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 ammable gases, as a safety or emergency stop
device or in any other application where failure of the product could
result in personal injury. Take electrostatic discharge precautions
during installation and do not exceed the device ratings.
Mounting
The water detector enclosure can be mounted directly to the oor of the area
requiring monitoring or on a nearby wall. Select a suitable installation area that
will enable enough room around the enclosure to allow for opening of cover
and mounting of an EMT or cable gland connector. Once a suitable spot is
selected, use the enclosure as a template and mark the 4 mounting hole
locations.
Select suitable mounting hardware that is compatible with the surface that the
water detector will be mounted to. As an example, if mounting on a wall with
wallboard, the use of wall anchors is recommended to create a secure installa-
tion. The mounting holes will accommodate #10 size screws, as shown in
Figure 1.
Once the enclosure is secured in place unroll conductivity cable and lay in
place. The cable may be laid in a straight line or in a serpentine conguration.
Be careful not to kink cable. Once laid in place, secure using the self-adhesive
cable clips provided. For best results adhere clips at each end of the cable rst.
Clips are provided to secure cable approximately every 1.5 m (5’). See Figure 3.
The enclosure has a hinged cover with latch. Open the cover by pulling
slightly on the latch on the right side of the enclosure and at the same time
pulling on the cover, as shown in Figure 4.
A 21 mm (0.8125”) hole is provided for connection of either a 1/2” conduit or
cable gland style connector. Insert the conduit or cable gland connector
through the hole and securely fasten using a locknut as shown in Figure 5.
Two security screws are provided which can be installed to help secure the
cover once wiring connections are complete.

Testing:
If eld testing is required, simply pour a small amount of water
at any point along the conductivity cable and relay will
activate. Once water evaporates, the relay will de-activate.

Relay Output Wiring
Wiring
• The conductivity cable is factory wired to the control board.
• Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent electrical shock or
equipment damage.
• Use 14-22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit with
wiring used to supply inductive loads such as motors. Make all connections in accordance with national and local
codes.
• Pull at least six inches of control wire into the enclosure, then complete the wiring connection according to the
wire diagram for the applicable power supply as shown in Figure 6.
• Connect the DC positive or the AC voltage hot side to the PWR terminal. The supply common is connected to the
COM terminal. See Figure 6.
•The relay has both Normally Open (NO) and Normally Closed (NC) contacts available. The relay output is available
on the NO/COM/NC terminal. Make connections before applying power as shown in Figure 7.
• Once all connections settings are veried, power can be applied.
