The Rain sensor is supplied with a 10-metre shielded cable. It is recommended that you do

not shorten this cable when mounting the unit. Coil the remaining length of cable or leave

a loop; This ensures that the cable will not be too short in the event of eventual extensions

with supports and mast components.

Connecting

See

Connecting sensors to the Weather interface WI2 (page 58)

After the connection and commissioning of the Rain sensor, the electronic systems require some

time before the rain detection functions properly. This time can be as long as 60 minutes when the

grid is dry. You can reduce this time to 1 minute as follows:

Place a clean wet sponge with tap water on the cartridge. Do not use demineralised water,

because it is not conductive.

The Rain sensor should detect rain after 1 minute.

Remove the sponge.

A short time after this, the Rain sensor should no longer detect rain.

Clean the rain sensor at least once a year, or earlier if the Rain sensor develops measurement

deviations (for instance, due to leaves or bird droppings). Clean the unit with a damp cloth and a

little mild detergent if required. Also check for corrosion or any other damage to the surface of the

sensor. Replace the sensor if the surface has been damaged.

Do not use aggressive cleaning and/or abrasives. This damages the gilded contact surface

of the Rain sensor.

Make sure that no moisture, dirt or dust enters the housing when opening the Rain sensor.

This can negatively impact the measurement.
