Dalamatic Insertable Dust Collectors – Series DLM V
Installation, Operation and Maintenance Manual
COMMISSIONING
It is a requirement of the Supply of Machinery (Safety) Regulations 1992
to provide adequate isolation and emergency stop facilities. Due to the
varied nature of site installations this cannot be provided by Donaldson
but instead is the responsibility of the customer.
When making your preliminary checks, or during the start-up sequence,
particularly note that on collectors fitted with an explosion panel the
cleaning system should not be operated on its own for longer than
necessary as the positive pressure produced could weaken the Membrex
membrane.
Commissioning check list
Ensure the Dalamatic dust collector body is securely bolted over the
aperture.
Ensure that all ducting is complete and all detachable panels are in
position.
Ensure header cover seal is intact on the collector, then secure the cover.
Ensure collectors fitted with antistatic filter elements and/or explosion relief
are suitably earthed.
Where fitted, ensure explosion relief panels are venting to a safe area.
Ensure controller is connected to the correct voltage and that the pulse
interval and duration settings are correct. For 24V DC ensure polarity is
correct. It is essential that the controller is earthed for both AC and DC
connections.
Ensure electric power is available.
Ensure the compressed air manifold has sufficient protection for over-
pressure.
Start the compressor and check that the air supply is maintained at the
recommended pressure.
Switch on the controller and check that all valves operate in sequence by
‘feeling’ pulses in rubber hoses (look and listen for exhaust pulses). As each
valve operates, the air pressure reading should drop to approximately 50%
of the initial setting and then return to the initial value.
Check fan motor for correct rotation and that the full load current is not
exceeded. (Refer to the fan rotation label located above the fan inlet eye in
the exit header section of the dust collector).
If applicable, start up the main fan and equipment being served.
Verify operation of the interlocks and audible warning system if fitted.
If any of the above check boxes are not ticked, then the reasons why should be
investigated. (Refer to fault location table in ‘Maintenance’ section).
