• Building instrumentation
• Weather stations
Functional description
The large sensor area reacts to rain or snow. The switch polarity and sensiti-
vity are adjustable. The optionally switched heater prevents freezing or dew
formation and accelerates drying. In the maximum sensitivity setting, the de-
vice is also suitable for recognizing fog. The mast or wall mounting bracket,
which is available as an accessory, enables easy installation.
Typical applications are in nurseries, in agriculture, in building services, but
also in home and garden.
Application
The rain guard is fi tted with a relay contact for switching low voltages 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
45 ° from horizontal. Mounting of the Rain Sensor should be done at a place
which is freely accessible for rain. Dripping water can adversely delay swit-
ching back or can lead to a permanent ON/OFF of the contacts.
Connection
After removing the sensor cover, the control cable is to be inserted in the
cable gland M16.Supply voltage is to be connected to the terminals VCC and
GND. Terminals NC, COM, NO are the potential free changeover contacts for
switching.
