start-up sequence
Having completed all the necessary checks, the equipment may be put into
operation. A typical installation, as shown in Figure 9, should be started up as
follows:
1 Start up compressed air supply.
2 Set the equipment being served, if applicable, in motion.
3 Switch on discharge equipment (if applicable).
4 Switch on controller.
5 Start main fan.
shut-down sequence
At the end of any period of operation it is most important that all residual
deposits are cleared from the filter elements, casing, discharge hopper
and equipment being served. To achieve this, equipment should be
shut down in the following order:
1 Stop main fan only, leaving controller and compressed air supply switched
on to allow filter to be cleaned ‘off-line’.
To enable off-line cleaning, refer to controller manual.
This procedure is not recommended where explosion panels are
fitted, as damage could result to the Membrex membrane. In such
cases consult with Donaldson.
2 After 10-15 minutes, switch off controller and compressor but leave discharge
equipment running to ensure that it is emptied.
3 After a further 5 minutes, switch off the discharge equipment if applicable.
Where the dust being handled has self-heating properties, it is important
to remove any deposits in the dust container to reduce the risk of an
explosion.
Adherence to the above procedure will ensure that a DCE 2000 Series collector
installation is maintained at optimum efficiency.
On installations where the inlet duct is relatively short, this procedure
may result in a dust emission occurring at the inlet and therefore may
not be an appropriate procedure if the dust being handled is dangerous.
Therefore a Risk Assessment must be carried out to ensure the final
procedure is safe.
