1.8 General risk matrix Operation The safety regulations prevailing at the operator’s location are mandatory and must be observed at all times. Before making an intervention, the process must be stopped, i.e. all mechanical movement must be stopped and it must be ensured that no automatic motion can occur. Missing safety devices If the fan is equipped with safety devices, they may neither be modified nor removed.
Dangerous media Depending on the mode of operation, fan parts may come in contact with dangerous media. Work on the fan or carrying out maintenance work is not allowed during operation. Before carrying out any work, any dangerous media must be removed from the system and, when required, must be neutralized and secured in such a way that an inflow of dangerous media is prevented. 1.9 EC conformity of the COLASIT fan The fan was designed, built and tested to Directive 2006/42 EC.
2 Explosion protection COLASIT plastic fans are suitable for the conveyance of gases in Zone 1 or 2 (Equipment Category 1 or 2) depending on the model. COLASIT plastic fans are not suitable for the conveyance of gases in Zone 0 (Equipment Category 1). The zone classification of the conveyed medium and the site of installation must be made known by the fan operator so that COLASIT can take the necessary measures to prevent the risk of ignition.
2.1 Fan Ex marking The Ex marking is located on the rating plate of each ATEX fan. On a fan of Equipment Category 2 (Zone 1), it looks like this II 2/3G c T3 CE-marking Marking denoting prevention of explosions II Equipment Category II, for all Ex applications which do not fall in Class I (mines and surface workings).
Store the fan in a dry, weather-protected place and cover with a tarpaulin to protect it from dust and soiling. If stored for over one year, test whether the fan bearings rotate freely before putting into operation. 4 Installation, configuration Before installation, check whether all the locking screws (including the motor screws) are tightened properly. Check the electrical connections if wired at the factory.
5.2 Drive The fan is driven by an electric motor which is connected to the impeller shaft either directly or via a V-belt. The motor electrical specifications are indicated on the motor’s rating plate or in the motor manufacturer’s data sheet. When speed is controlled by means of a frequency converter, the maximum speed is limited by COLASIT to the value indicated on the manufacturer’s rating plate.
7 Maintenance, repair, cleaning 7.1 Preparation Before any work is carried out on the fan, the fan must be set to its "safety position". The „safety position“ is defined as follows: - The drive must be currentless and the main switch secured against switching on, The fan impeller can be manually rotated, Fan must be flushed with fresh air and be condensate-free, Fan must be at room temperature, Personal protective equipment must be available and it must be worn.
After replacing a V-belt, check the tension after 1 to 4 hours of operation and retension as necessary. The fan bearings are maintenance-free. The bearing temperature of 70ºC may not be exceeded. In cases of high stress (environment) the grease quantity loses its lubricity over time due to mechanical stresses, ageing and increasing contamination. This issue can reduce the service life of the bearings.
Logbook For your own safety and as an aid to personal responsibility, we recommend the keeping of a logbook for the entire period during which the fan is in service. All events should be recorded in the logbook. In case of damage and also in case of an accident, this document is the first source of information. For example, enter the date and your signature: Start and end of a work cycle Special events, even if they do not concern the fan itself (e.g.
Fault Fan fails to reach its rated speed Possible causes Intake or pressure duct blocked Remedy Remove blockage Electrical switching mechanisms incorrectly adjusted Check motor protection setting and reset if necessary Motor winding defective Drive motor drive not correctly designed Please consult the manufacturer Please consult manufacturer to verify starting torque Grinding noises when fan is running or starting Intake duct fitted under tension Remove intake duct an realign Rise in temperature o
