Vwind-Si
Wind Speed Sensor for Si-RS485TC-2T-v
Short Description
Our wind speed sensor Vwind-Imp comes equipped with a high-quality fibre-reinforced plastic cup star and
with a weatherproof cable. Thanks to the use of top quality components the sensors achieve high accuracy and
are ideal for use in field environments (PV plants).

Safety Instructions
The installation and assembly of electrical equipment must be carried out by electrically qualified persons.
The sensor may not be used with equipment whose direct or indirect purpose is to prevent human death or
injury, or whose operation poses a risk to humans, animals or property.
Electrical Connection
This sensor is designed for connecting to the Si- sensor type Si-RS485TC-2T-v. For connecting, remove the
protection cab of the 2-pole socket of the Si-RS485TC-2T-v and connect the Vwind-Si. To lock the cable
connector, the threaded ring is tightened until it is ‘finger-tight’ (approx. 50 Ncm).
Installation Instructions
Storing, mounting and operation under weather conditions is only allowed in vertical position, as otherwise
water can get into the sensor. So an installation with roof inclination is not allowed.
No installation in wind protected areas or in wind shadow of any construction.
On flat roofs a installation in the middle of the roof is preferable.
The wind sensor must be integrated into the lightning protection system.
The sensor cable must be fixed at the mounting construction.
The screws for fastening the sensor at the mounting angle are tightened with a maximum of 1.5 Nm.
Maintenance
Heavy air pollution can clog up the slit between the rotating and the stationary part of the wind sensor. This slit
must be kept clean.
After longer use abrasion might occure at the bearings and the reed relais. This can cause a higher starting
torque or missing output impuls. Therefore were commend a yearly maintenance and checking of the rotating
ability of the cup star.
User information
The sensor is designed for the measurement of natural wind speed. The warranty is for 1 year from the date of
the invoice for the intended use. M&T does not accept any liability for possible losses or damage due to the
incorrect usage of the sensor. Liability for consequential damages is excluded.
