3. LITERATURE Workshop Manual The workshop manual covers all workshop maintenance for the DC 6000. Some very simple and ob- vious repair work has been omitted. The manual is divided into numbered chapters as well as chapter headings that are specified in bold at the top of each page �...
General • No one may repair the DC 6000 unless they have read and understood the contents of this workshop manual. • This workshop manual is written for personnel with general knowledge about the repair and service of DC 6000.
Machine Stop Button The DC 6000 is equipped with an machine stop button which will quickly shut down power to the DC 6000. Note that the electrical cabinet will still be energized even when the machine stop button is pushed.

FUNCTION TEST 8. FUNCTION TEST Function Test • Connect the Vacuum to a power outlet� • Push the green button. A white lamp is lit up, and the compressor will start to build up pressure. It can take around 30 seconds until the compressor has reached the correct pressure. (Note: if the correct pressure is main tained the compressor won’t engage) •...
FUNCTION TEST Electrical Functions The electrical functions of the DC6000 are divided in a 400/480 V 3-Phase system and a 1-phase 230 V system. The 400/480 V 3-Phase system is used to power the Blower Motor and to power the Auxiliary power outlet used to power the connected grinder.
FUNCTION TEST Blower Motor The blower motor is powered by the 400/480 V 3-phase system and is controlled by the PLC. The PLC sends a 230 V signal to the overload protection Q1 and it engages one of the 2 power contactors K1 and K2. The phase sequence re- lay K3 determines which one the contactors that engages according to how the phases in are connected.
FUNCTION TEST Auxiliary Power Outlet The auxiliary outlet is connected directly to the main power cable and is energized as soon as the main cable is con- nected to a power source.
FUNCTION TEST The PLC is powered by the 230 V transformer and is used to control the on/off function for the blower. And the manual/automatic purge function. Its input is controlled by the settings on the control panel. And its output is a 230 V control signal for the purge solenoid and to the blower.
FUNCTION TEST Transformer 230V The 230V Transformer transforms 400/480V 3-phase power to 230V 1-phase power. The 230V is used to power the PLC, the Air Compressor and its pressure switch. All of the in/out signals from the PLC are also a part of the 230V electrical system��...
FUNCTION TEST Purge Function The Purge function is the automatic filter cleaning system. It cleans the airfilter by releasing compressed air through the filter which allows the dust to fall down in the longopac bag. The Purge function can be in Automatic or Manual mode.
FUNCTION TEST Hour Meter The Hour meter is used show the running time for the blower motor. Its mounted in the electrical cabinet and reads the signal between the Overload Protection (Q1) and the Phase sequence relay (K3).
TROUBLESHOOTING TROUBLESHOOTING Troubleshooting WARNING! Most accidents involving machines occur during trouble shooting, service and maintenance as staff have to locate themselves within the machine’s risk area. Prevent accidents by being alert and by planning and preparing the work� The engine should be switched off during operations described in this chapter unless otherwise stated. All checks involving electric components should only be performed by a licensed electrician.
Clean the machine exterior� Check the filter and shake out the dust when needed. If necessary, wash the filter with water according to Husqvarna's recommendations. Never clean the filter using air pressure. See Cleaning / replace filters in OM Check the dust level inside the filter housing.
SERVICE AND MAINTENANCE Filter The filter is made of a polyester material and can be washed with water as necessary. Change filter after 500 hours or after 6 months� •In order to avoid destruction of the finish or ePTFE membrane clean the filter elements with a gentle soft jet of water.
