Functional description
The large sensor area reacts to rain or snow. The switch polarity and
sensitivity are adjustable. The optionally switched heater prevents
freezing or dew formation and accelerates drying. In the maximum
sensitivity setting, the device is also suitable for recognizing fog.
Application
up to 30 V DC/AC which can be used to operate any switching device
e.g. a marking control device. Sensitivity can be adjusted within a wide
range. The device is provided with a heater for faster drying and snow
recognition.
Mounting
Installation of the rain sensor unit should be carried out by only
authorised personnel. The applicable safety regulations should be
followed ! The Rain Sensor can be installed on a wall/mast mounting
bracket. If such accessories are not used, care should be taken that
the mounting angle is approximately 30 ° from horizontal. The points
of sensor area must be on the down side. Mounting of the Rain Sensor
should be done at a place which is freely accessible for rain. Dripping
water can adversely delay switching back or can lead to a permanent
ON/OFF of the contacts.
