Context
●
Prepare a location-type water sensor or water detection cable of the same
model.
●
The location-type water sensor consists of a water leakage locator, tieline,
and water leakage location cable. The water detection cable is laid out on the
floor. The liquid level sensor is deployed around the collector. The water
detection cable and the liquid level sensor are connected using the lead wire.
●
Recommended tool and material: crimping tool
Procedure
Step 1 Replace the water sensor.
1. Pull out the water detection cable from the lead wire port on the water
leakage locator.
2. Remove the water leakage locator from the DIN guide rail.
3. Install the new water leakage locator on the DIN guide rail with the latch
facing upwards.
NO TE
– Touch grounded devices or pipes to eliminate ESD before taking the water sensor
module.
– Place it gently. Prevent it against mechanical impact and collision. Keep it dry.
– Prevent it against metal filings, grease, pipe paint, and other contaminants.
4. Connect one end of the black quick-connect terminal of the lead wire from
the liquid level sensor to the location-type water detection cable, and connect
the other end of the quick-connect terminal to the sensor.
Step 2 Replace a water detection cable.
1. Remove the faulty water detection cable from the port.
2. Install a new water detection cable.

Follow-up Procedure
Check whether the new location-type water sensor works properly. Connect the
network cable between the water sensor and the ECC800-Pro, immerse the water
detection cable in water, and check whether an alarm is raised. If an alarm is
raised, the replacement is complete.
