intervention<br />
Check insulation between<br />
windings and from windings to<br />
earth (ground)<br />
˜ ˜ Fan motor faulty Check and replace if necessary<br />
˜ ˜ Faulty fan alarm relay Check and replace relay<br />
˜ ˜ Drop in power feeding<br />
voltage<br />

protections<br />
Check voltage stability and fit<br />
appropriate protection if<br />
necessary<br />
