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
The rain guard is fitted 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 30
° from horizontal. The points of the sensor area must be on the downside.
Mounting of the Rain Sensor should be done at a place that is freely
accessible for rain. Dripping water can adversely delay switching 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.
The supply voltage is to be connected to the terminals VCC and GND.
Terminals NC, COM, NO are the potential free changeover contacts for
switching.
Precautions:
- The device is suitable only for low voltages and should not be operated on mains supply!
- The relay contact is only suitable for low-value signals and should not come in contact with the mains supply!
- The protection type is valid only with an intact, complete casing, cover screws, and cable gland properly tightened, and the cover gasket should always be available on the sensor cover!
- The suitability for certain applications is to be checked by the user
Settings
Signal generator output (optional)
At the connection terminals (Pin BUZ and GND) a passive Piezo signal generator
can be connected. The condition of signal (acoustic
signal for dry or wet) can be selected with the plug links S1-S2 or S2-S3. In
the default position S2-S3, the signal generator is inactive for rain.
Switching mode
The switching mode of the relay (pickup or dropout with rain) can be selected
with the plug links T1-T2 or T2-T3. In the factory settings, link T1-T2 is
connected and the relay closes if the sensor surface gets wet.
Heating
The sensor surface is heated if the link of HZ1-HZ2 is connected. To ensure
faster drying and for operation below freezing point, the heater should be
switched on. For sensing fog, the heater can be switched off.
Sensitivity setting
The sensitivity for detecting rain can be adjusted with the potentiometer.
Rotating the potentiometer clockwise results in a higher sensitivity.
For detecting rain mostly the middle position of the potentiometer is
suitable. Please note that no function takes place in the end position!
Indicators
There is a green LED on the device to indicate the operation status and a
red LED to indicate the switch position (means relay contact closed).
Maintenance
The Rain Sensor unit is almost maintenance-free. The sensor surface must be
occasionally cleaned with a moist cloth ( e.g. once annually, depending on the
place of installation). In case of the persistent condition, even if it does
not rain, it triggers due to strong
