Important information
▪Read instructions carefully before installation. Keep the instructions for future reference.
▪Sensor WLA 330 should be installed in accordance with current national legislation.
▪Disconnect from mains supply before installation or removal of the sensor and before carrying out any maintenance or service work
and ensure that it cannot be reconnected unintentionally during this time.
▪If the sensor gets activated, the window operator automatically closes the window. For personal safety, never have your hand or body
out of the window without disconnecting from mains supply.
▪Do not paint or lacquer the rain sensor.
▪Dirt on the sensor may cause operating problems. Therefore, it is recommended to clean the rain sensor with a soft wet cloth once or
twice a year or when required.
▪Electrical products must be disposed of in conformity with national regulations for electronic waste and not with usual household
waste.
▪The packaging can be disposed of with usual household waste.
▪WLA 330 is a low-voltage product that complies with the requirements of the EMC directive concerning use in household, trade and
light industry.
▪This product has been designed for use with genuine WindowMaster products. Connection to other products may cause damage or
malfunction.
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.

Note
Factory setting = operation, meaning switch 1, 2, 3 and 6 = on and switch 4 and 5 = off.
Should there during installation be the need to disconnect the wind/rain drop out delay, set switch 1+2+3 = off (= Test).
Important! Once installation and star-up are completed, proceed with the wind speed setting required on site, meaning one or more of
the switches 1,2 or 3 MUST be on!
Remark: In the test setting, the activation and drop out delay is deactivated!

Information regarding switch 6:
Only the supply voltage (terminals 1+2) for the sensor is monitored.
The system will trip automatically in the event of a supply voltage failure.
Display: Red steady light in the sensor LED = Sensor tripped by wind or rain.
