Description
The wind/rain sensor comprises a wind wheel and a rain sensor surface.
This sensor is used for the automatic control of Smoke Control Units and ventilation central units.
The wind/rain sensor is equipped with a potential free change-over contact
having a contact rating of 60V/2A.
In the event of wind and/or rain, the change-over contact switches over from the N/C contact
to the N/O contact.
The settings for the wind trigger threshold, the actuation delay, the drop out delay
and the trip in the event of a mains failure are made by a 6 pole DIP switch in the sensor.
Operation / Function
Triggering by wind
The potential free contact switches when the (settable) wind sensor trips.
The red LED in the sensor is lit.
Remark:
The trip is reset 10 or 20 min. (settable) after the last sensor actuation.
