Working safety instructions in maintenance Instructions for Rosenberg fans.
Before any work whatsoever on the fan, the following must be in compliance:
+ Tasks must be carried out only by qualified specialist personnel in compliance with these instructions
and the applicable regulations.
+ Use an isolator to disconnect the drive motor from the mains!
If there is no isolator, disconnect all the drive motor's terminals from the mains.
+ Ensure that it is not possible for the fan to be started unexpectedly during maintenance or repair work
(e.g. use a lockable isolator switch).
+ Wait until the rotor has come completely to a standstill!
+ Check the surface temperature for the danger of burns.
+ Before maintenance work, use suitable media to remove harmful or dangerous materials which may
have entered the fan in combination with the conveyed material.
+ Carry out re-commissioning only after execution of the necessary safety tests.
Excluded from the above are tasks which can be carried out only in the operational state while complying with the applicable safety and accident prevention regulations, e.g. measurement of oscillation or shock pulses, the use of lubrication equipment to re-lubricate bearings during operation.
Failure to comply with these items may result in risk to life and limb for the maintenance personnel. If the state of the fan means that suitable repair measures are no longer possible, then the fan must immediately be taken out of use, and possibly replaced.
Maintenance intervals in maintenance Instructions for Rosenberg fans.
To maintain operation and safety, we recommend that at regular intervals fans are inspected for their functioning and condition by qualified expert personnel or by a specialist company, and that this is documented.
For this, the directives and safety regulations applicable to the specialist application must be complied
with. Failure to comply may result in risk to life and limb for the maintenance personnel.
The operator must specify and carry out regular inspections and cleaning, depending on the local conditions, especially if:
+ The conveyed material can cause imbalance in the rotor, e.g. through corrosion, abrasion, or material build-up.
+ Used for out-door application, subjected to hot, dry and raining weather conditions, this can help to prevent motor bearing failure.
+ Wear or contamination of the housing (corrosion, abrasion, material build-up) occurs
+ There are particular environmental conditions, e.g. environmental temperatures >40oC or <-
20oC, temperature variations > 20K, sea air, or temperatures/humidity's at which the creation of condensation may be expected.
+ Frequent changes in loads arise (! design of the motors for permanent operation SI)
+ Operation is not in a fixed location, e.g. temporary fans.
