Installation
SAFETY NOTE:
Prior to Installation ensure that all power sources are disconnected and locked-out and remain locked out during
Installation and set-up, as severe injury or death can result from Electric Shock due to contact with High Voltage
Conductors. Ensure all installations are in complance wth applicable electrical codes and that the installation is carried
out by qualified installers familiar with the relevant standards and proper safety procedures for high voltage
installations. Never rely on status indication on any device to determine if power is present .
Sensitivity:
Power the WLD-DTA and adjust the sensitivity potentiometer on the WLD-DTA by turning anti-clockwise until the LED
comes on, and then back clockwise until the LED goes off. Less sensitivity may be needed when long runs of cable are
used. Where short cables are used the LED may not come on even when set to maximum sensitivity.
Testing:
To test the installation put a wet cloth over the probes to simulate a water leak, the buzzer will come on. Remove the cloth
and remove power from unit to turn the buzzer off.
Audible Alarm Output:
Tthe jumper can be temporarily placed in the LO position to attenuate the alarm during commissioning.

Installation
1. Fix the AX-WPS in the location where leak detection is required.
2. The AX-WPS is fitted with a 2 meter leader cable that can be connected to a AX-WLD-DTA alarm
module. (A maximum of 200 meters is allowed for each AX-WLD-DTA).
3. Connect the 2-core leader cable to the AX-WLD-DTA alarm module sensor input (polarity independent).
4. Power the AX-WLD-DTA, and adjust the pot on the PCB anti-clockwise until the LED comes on, and
then back clockwise until the LED goes off
5. Test the sensor by placing a damp cloth over the stainless steel probes to simulate a water leak, the
buzzer will come on. Remove the cloth and power from the unit to turn the buzzer off.
6. More than one AX-WPS can be connected to a AX-WLD-DTA alarm module, as long as the total cable
run does not exceed 200 meters.
