Leak Minder ™ LDA-1B Leak Detection System Instructions
PLEASE READ ALL INSTRUCTIONS BEFORE INSTALLATION
Checklist of Materials:
a) Leak detection system in NEMA 4X PVC enclosure with alarm horn, alarm
indication light, and a test/silence switch.
b) Leak detection probe with 20 feet of cable
Operation:
The leak detection system will sound a loud speaker/horn and illuminate a bright red light
when a switch signal is detected from the leak detection probe.
The leak detection system controller enclosure is designed to be mounted on a flat surface
either directly on the tank or another location in close proximity.
1) FIRST. Calibrate the leak sensor. Leave the sensor outside of the interstitial monitoring
section of the tank while performing the calibration. Have a glass of water for sensor
calibration. Now, connect the wires from the probe to terminals marked “probe”, one wire is
white and the other black. Wire the white wire to the bottom “probe” terminal and black to the
top “probe” terminal. Now, connect the AC power input to unit marked “L” (line), “N”
(neutral), and “GND” (ground). Dip the sensor into the water to activate the alarm. Turn the
sensitivity screw counterclockwise for less sensitive and counterclockwise for more sensitive.
Adjust sensitivity to desired level. When complete put a small dab of silicone over the
sensitivity screw to prevent debris from fouling the adjustment screw. Be sure to de-
energize the AC power to the leak detection controller before going to step 2.
2) SECOND. If utilizing the auxiliary relay feature wire in to the terminal marked “NC/C/NO”.
You have a choice of a normally open (NO) or normally closed (NC) contact. Relay is rated
at 230 VAC/5A. You will have to make a hole in the enclosure housing to run the alarm relay
wires to an external device such as a PLC or control system.
4) THIRD. If AC power has already been permanently wired in you can now energize the circuit,
if not, wire in the AC power to the terminals labeled “120VAC”. Unit requires 110 VAC primary
power. Terminals are clearly marked “L” (line), “N” (neutral) and “GND” (ground).
5) Testing- Prior to dropping the leak sensor into the interstitial section of the tank, test the
operation again by dipping the probe in water to simulate proper activation. The alarm horn
and light will activate. To deactivate remove the leak detection probe from the water. You
may silence the alarm horn by pushing UP on the switch (marked “silence) on the upper right
side of the enclosure. The alarm light will continue to illumunate if liquid is present. Unit
automatically resets when liquid is no longer present. The controller may be tested for proper
operation anytime by pressing DOWN on the switch to test the leak controller.**
**the TEST feature does not test the probe, only the controller. If you suspect there is
a problem or failure with the probe, repeat STEP 5. Always remove and inspect and
clean probe with soapy water or Simple Green after a leak has been detected!
6) Install leak sensor in the interstitial void of the tank. Installation and setup are now complete.
