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 exhaust 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.
Parallel unit / mounting kit MP-P
Two fans connected in parallel (Fig.15) provide
large air volumes with the corresponding pressure
rate and they meet the requirements for garage
ventilation and smoke extraction in particular.
Two identical fans arranged side by side work in
the same duct system.
Scope of delivery:
- Extension ducts (2 pcs.),
- Backdraught shutters (2 pcs.),
