Dust Collectors - Series CPC
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.
Installation check list
Ensure the dust collector is securely bolted to the support structure.
Ensure the support structure is securely bolted to the floor.
Ensure all ducting is complete and all detachable panels are in position.
Ensure collectors fitted with an earthing post are suitably earthed.
Where fitted, ensure explosion relief panels are venting to a safe area.
Open the access door(s) and ensure the seal is intact, then close and secure
the door(s).
Ensure controller is connected to the correct voltage and 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 the air supply is maintained at the recommended
pressure.
If applicable, start up the discharge equipment (e.g. screw conveyor, rotary valve,
belt feeders etc.).
Switch on the controller and check that all valves operate in sequence (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.
If fitted, start up the main fan and check for correct rotation and the full load
current is not exceeded (refer to fan rotation label located on rear panel of fan
section).
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).
Start-up sequence
Having completed all the necessary checks, the equipment may be put into operation.
A typical installation, as shown in figure 7, 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.
