3.7 Bearing condition diagnostics
Type: LZD-Basic and LZD-Comfort
The Helios bearing condition diagnostics system serves to securely monitor the functionality of motor bearings in
the drive motor of the smoke extraction fan. The system optionally allows the early detection of imminent bearing
damage by constantly or occasionally monitoring the bearing conditions. The bearings are not replaced periodically,
but depending on the actual wear. In this respect, the test and maintenance plan in these Installation and Operating
Instructions must be observed. Before operation and the use of bearing condition diagnostics, the separate Installation
and Operating Instructions for the monitoring system must be observed.
Information on other smoke extraction accessories can be found on the internet (www.heliosselect.de), main catalogue
or the Helios sales documentation.
