1.3 Warranty claims – Exclusion of liability
All versions of this documentation must be observed, otherwise the warranty shall cease to apply. The same applies
to liability claims against Helios. The use of accessory parts, which are not recommended or offered by Helios, is not
permitted. Any possible damages are not covered by the warranty. Changes and modifications to the unit are not per-
mitted and lead to a loss of conformity, and any warranty and liability shall be excluded in this case.
1.4

Certificates - Guidelines

If the product is installed correctly and used to its intended purpose, it conforms to all applicable provisions and CE
guidelines at its date of manufacture.
1.5

Shipping

The fan is packed ex works in such a way that it is protected against normal transport strain. Carry out the shipping
carefully. It is recommended to leave the fan in the original packaging.
The unit may not be exposed to any strong impacts during shipping and storage.
In the same way, the unit should be closed properly (cover and fittings), so that moisture cannot penetrate.
1.6

Receipt

The shipment must be checked for damage and correctness immediately upon delivery. If there is any damage,
promptly report the damage with the assistance of the transport company. If complaints are not made within the agreed
period, any claims could be lost.
1.7

Storage

When storing for a prolonged time, the following steps are to be taken to avoid damaging influences: Unit protection
by dry, airtight and dust-proof packaging (plastic bag with desiccant and humidity indicators). Vibration-free, water-tight
and constant-temperature storage at a temperature in the range -30 °C to +70 °C.
In case of reshipment (above all, over longer distances; e.g. by sea), it must be checked whether the packaging is suit-
able for the form and route of transport. Damages due to improper transportation, storage or putting into operation are
not liable for warranty.
1.8

Personnel qualification

In the context of this documentation and the information on this product, the qualified personnel means the persons
who are familiar with the installation, assembly, start-up and operation of the unit and the associated risks and have the
appropriate professional qualifications for their roles.

General description

The Helios Bearing Condition Diagnostic System is a system for the continuous or occasional bearing monitoring of the
motors of Helios fans operated directly on the mains supply, consisting of an evaluation unit LZD Basic or LZD Com-
fort and sensors to record the vibration acceleration and bearing temperatures. In this respect, the Bearing Condition
Diagnostic System works independently of the nominal speed of the drive motor and it is therefore suitable for both 1-
stage and 2-stage drive motors (no monitoring in case of frequency inverter operation).

1.10 Functions

The following systems are available for monitoring:
LZD Basic: Recording, monitoring, visualising and forwarding the bearing condition.
Recording the vibration acceleration.
LZD Comfort: Recording, monitoring, visualising and forwarding the bearing condition.
Recording the vibration acceleration and bearing temperatures.
The Helios Bearing Condition Diagnostic System is designed for attachment to/in the fan and may only be used for this
application.
The evaluation and visualisation of bearing conditions takes place with a simple visual status display green-yellow-red
(see below) on the evaluation unit, but it can also be connected via the ModbusRTU to the existing network on site or
the building management system for monitoring multiple fans.
Connection to a PC by means of USB is possible with the corresponding accessories.

1.11 Scope of delivery/Components

The Helios Bearing Condition Diagnostic System is already mounted to the fan to be monitored at the factory prior to
delivery. With regard to fan types B AVD/B VAR/B AMD, the Bearing Condition Diagnostic System is mounted to a hol-
der and must be mounted on the flange depending on the installation location of the fan.
Ensure that the condensation drain in the evaluation unit (Fig.1) is directed downwards (deepest point) and that
the condensate is able to flow out freely.
