Claber Rain Sensor

Product Information

Product Code: 90915

Installation and Operation

The Claber Rain Sensor is designed to prevent unnecessary water wastage by suspending sprinkler start-up in the event of rain. It should be installed in a location exposed to rainfall and away from sprinkler jets.

Page 1: Introduction and Installation Location

The Rain Sensor avoids wasting water by suspending sprinkler start-up in the event of rain. Install the Rain Sensor in a position exposed to rainfall and out of sprinkler jets.

Diagram 1: Shows the Rain Sensor being installed, with an indication of 'OK!' for proper placement and 'NO!' for incorrect placement, suggesting it should be exposed to rain and not directly under a sprinkler.

Diagram 2: Illustrates the sensor's function, showing rain falling on the sensor ('OK!') and the sprinkler system being suspended ('NO!').

Page 2: Component Description

Description of Components:

• 1) Top cover
• 2) Internal floater
• 3) Container
• 4) Fastening bracket
• 5) Bracket fastening screws

Page 3: How it Works

For correct operation, position the floater inside the container with the special fins facing upwards and the orange base facing downwards. The top cover must remain closed to prevent foliage or impurities from entering the sensor.

When the Rain Sensor container is full (at least 5 mm of rainfall), it sends a stop signal to the timer. Depending on the model, the timer stops the current irrigation cycle or the next cycles as programmed.

Diagram 1: Shows the internal components of the Rain Sensor, including the floater and container, with an 'OK!' and 'NO!' indication, likely related to correct assembly or function.

Diagram 2: Depicts the sensor in operation, showing a sprinkler system being activated and then suspended due to rain detected by the sensor.

Page 4: Installation - Tap Timers

Remove the bridge connector and connect the Rain Sensor to the timer by inserting the connector into the housing. If the Rain Sensor cable is not connected to the timer, leave the bridge connector inserted. If it is not inserted, the timer will only work in manual mode, not in automatic.

Diagram 1: Shows the connection of the Rain Sensor to a tap timer, highlighting the removal of a bridge connector and insertion into the timer's housing.

Diagram 2: Illustrates the connection process, showing the Rain Sensor wires being connected to the timer.

Page 5: Installation - Wall-mounted Timers for Underground Irrigation

For timers equipped with special housings (e.g., Multipla type timers), remove the bridge connector from the timer and connect the Rain Sensor by inserting the wires into the terminal board.

If the timer is not equipped with special housings (e.g., Aqua-Home and Cometa type timers), connect the Rain Sensor to the timer by disconnecting the common wire.

Diagram: Shows a wall-mounted timer and the connection of the Rain Sensor to a terminal board, with labels for different timer functions.

Page 6: Installation - Wall-mounted Timers for Underground Irrigation (Alternative)

For timers not equipped with special housings (Aqua-Home and Cometa type timers), connect the Rain Sensor to the timer by disconnecting the common wire.

Diagram: Illustrates the connection of the Rain Sensor to a timer by interrupting the common wire, showing a wiring diagram with labeled terminals.

Page 7: Installation - Control Unit

Connect the yellow and grey wires to the Rain Sensor wires inside the control unit. If the Rain Sensor is removed from the system, reconnect the yellow and grey wires.
