be fed via the DM-valve.
For the conversion and/or retrofitting, the 1K mixing tube (order no. 2372283) is to be
replaced with the 2K mixing tube (order no. 2393711) with integrated static mixer.
As a wearing part, the static mixer can also be ordered separately and/or exchanged.
A continuous dosing of A and B is to be ensured. Also, the mixing ratio is to be ensured via
the dosing pump (via hardware) or via different rotation speeds by a controller. Flushing
must take place via the flushing valve before the respective dosing pump.
7.3.3 PRESSURE RELIEF/WORK INTERRUPTION
The pressure must always be relieved:
– when the spraying tasks are finished,
– before carrying out maintenance work on the spraying system,
– before carrying out cleaning tasks on the spraying system,
– before moving the spraying system to another location,
– if something must be checked on the spraying system,
– if the bell is removed from the high-speed rotary atomizer
The components for pressure relief on a CE-compliant spray system include:
– Air cock with pressure relief hole mounted between compressed air source and pneumatic pump.
– Product pressure relief valve mounted between pump and high-speed rotary atomizer.
Pressure Relief Procedure:
1. Switch off high voltage.
2. Deactivate valves in valve block via the controller.
3. Deactivate main needle valve.
4. Switch off steering airs SA1 and SA2.
5. Use stop air (STA) to set speed to "0".
A value between 50–100 rpm is shown in the controller display.
Notice
Always follow the procedure described above if pressure relief is specified in the instructions.
