After installation of rope style leak detection sensor in its desired location, it is very important to test the sensor to verify correct
installation. This applies to all rope-style leak detection sensors (E-LD/ E-LD-LC / E-CD, etc.).
To test the rope style leak detection sensor;
1. Configure the sensor (page 48). (Normal Status set to “Open”, Sampling Period set to 5 seconds.)
2. Place approximately one table spoon of tap water across the sense cable so that the 2 thin sensing wires are connected
by mutual contact with the water. Do NOT use distilled water as water must be conductive.
3. Monitor the sensor (page 31) to see the sensor “Value” change from “Open” (dry) to “Closed” (wet). (How quickly the
change occurs is based on the amount of impurities in the water, so allow up to 30 seconds).
4. Dry the exposed area of the sensor and the sensor “Value” should change back to “Open” within 30 seconds.
If the sensor fails to behave in this manner, contact NTI for support.
This completes the testing of the sensor.
