Sensor
1. TECHNICAL SPECIFICATIONS (@ 20°C)
- Power supply:
9-15 Vdc
- Contact capacity: 100 mA @ 12 Vdc
- Consumption:
6mA with open contact, 10mA with close contact
2. ELECTRICAL CONNECTIONS
- The module has to be installed from technical qualify staff to respect all the rules and laws in forces on the territory.
- Work with caution on the module, use suitable tools.
- Verify that the line of supply doesn't result from circuit for th lighting.
- The line of supply has to be protected from a suitable magnetothermic or differential device..
- In case of many radio installations in the same system, the distance between them doesn't have to be less than 1,5m.
- Do not modify or replace parts without autorization of the manufacturer.
2.1 Power supply
To power the module, use PS12 power supplies (with clean contact output) or AT12 (radio rain signal). The power supply has to be
apply to terminals 3 and 4.
2.2 Rain contact
If the sensor relives the presence of rain, the contact betwenn terminals 1 and 2 close.
3. RAIN SENSOR: WORKING LOGIC
If the sensor relieves rain, the rain contact closes (terminals 1 and 2). The contact opens when the plate of the rain sensor is dry enough. It is possible sets up
the sensor so that the rain contact stay close at least 2 minutes (see point 3.1). When contact is close the LED is ON. When contact is open the LED is OFF.
3.1 Rain contact working logic
The microswitch J1 allows to select the logic of working of the output contact:
J1 OFF
With rain, the contact is closed for at least 1 second; the contact is re-opened when the plate becomes dry enough.
This is the default setting from the factory.
J1 ON
With rain, the contact is closed for at least 2 minutes; the contact is re-opened when the plate becomes dry enough.
3.2 Little drops sensibility
Some atmospheric phenomenon (e.g. dew, fog, etc..) tends to deposit some little drops on the plate of the sensor that could be interpret as a presence of rain.
Through the microswitch J2 it is possible choose between two levels of sensibility to the little drops:
J2 OFF
This setting makes the sensor more sensitive to the fine rain, consisting of very small droplets; however, could
happen closing of the contact in case of dew, fog, etc. This is the default setting from the factory.
J2 ON
This choice makes the sensor less sensitive to fine rain and small drops that characterize atmospheric phenomena
like dew, fog etc.
4. FAQ
? The rain sensor doesn't close the contact in presence of rain.
- Just powered, the sensor briefly switch ON the LED. If it doesn't happen check the presence of power supply in terminals 3 and 4.
? The contact of the sensor is not stable, that's close and open without apparent reason.
- Bring the microswitch J1 to ON position.
