Fig. 1: Safety Information
2.4 Safety features
Safety features must be checked with the system depressurized:
➤before initial commissioning,
➤always before starting work,
➤after completion of setup work,
➤after cleaning, maintenance and repair work!
Check list:
5Main switch and stop button on control cabinet moveable?
5Lead seal on the safety valve still intact?
5Safety valves externally free of damage?
5Function of compressed air shut-off valve correct?
5Correct functioning of safety levers on spray gun?
WARNING
If one of the safety features is missing or not fully functional, the operating
safety of the system cannot be guaranteed!
➤If you discover any faults on the safety features or other deciencies on
the system, stop operation of the system immediately.
➤Only resume operation of the system after the fault has been completely
rectied.
2.4.1 Main switch and stop button on control cabinet
The electric system of the device can be switched on and off with the main switch
on the control cabinet (see chapter 3.3.1 on page 22) .
The stop button allows you to interrupt the compressed air supply for the me-
tering pump and thus shut it down.

Safety
2.4.2 Safety valves
The DUOMIX 333 PFP is equipped with safety valves:
➤in the air intake of the air maintenance unit to
the metering pump (see Fig. 2),
➤in the air motors of the feed pumps and the
ushing pump,
➤in the pressure vessels for both components.
The safety valves ensure that the max. permissible
air inlet pressure is not exceeded. If the air inlet
pressure exceeds the xed limiting value at one
of the points mentioned above, the corresponding
safety valve will blow off.
Fig. 2: Safety valve
WARNING
If the maximum permissible air inlet pressure is exceeded, components may
burst. This may result in damage to persons and property.
➤Never allow the system to run without or with defective safety valves!
➤If a safety valve needs to be replaced, you can nd the corresponding
order number on the machine card.
➤When using new safety valves make sure that the valves have been
set to the max. permissible air inlet pressure of the DUOMIX 333 PFP as
required for the mixing ratio (see type plate or machine card) and sealed
with a lead seal.
Changing the mixing ratio may cause a change in pressure ratio and thus re-
quire the adaptation of the max. permissible air inlet pressure of the metering
pump. In this case you would have to replace the safety valve of the meter-
ing pump and the type plate – you should absolutely contact WIWA.
2.4.3 Compressed air shut-off valves
The compressed air shut-off valve on the air maintenance unit interrupts the air
supply for the entire system.
Open
Closed
Fig. 3: Compressed air shut-off valve opened Fig. 4: Compressed air shut-off valve closed
Furthermore, the system is equipped with further compressed air shut-off
valves for interrupting the air supply to individual system components, like e.g.
to feed pumps or pressure vessels.

Translation of the original operation manual DUOMIX 333 PFP 15
PFP_Version 2_BAoDB_en_1410 · rs
Safety
The functional principle of all pressure and material shut-off valves is identical:
➤Set in ow direction to open,
➤Set across the ow direction to close.
Once the air supply is cut off, the system is still under pressure.
Before starting work on the system you must therefore relieve the pressure
completely.
2.4.4 Safety rupture discs
The safety rupture discs make sure that the
permissible operating pressure is not consider-
ably exceeded. They are located in the screw
tting behind the intermediate piece.
If a safety rupture disc is damaged material will
escape from the hose of the safety rupture disc
safety device.. In this case the safety rupture
disc must be replaced immediately. Fig. 5: Safety rupture disc seat
You nd the corresponding ordering data on the machine card A new safety
rupture disc must be installed with the coloured side facing towards the pres-
sure.
2.4.5 Ground cable
The ground cable is used to prevent elec-
trostatic charging of the unit. The ground
cable is already connected to the cart of
the unit when it is delivered. In order to
ground the unit, connect the clamp of the
ground cable to an electrically conducti-
ve object outside explosive atmosphere
areas. Fig. 6: Ground cable
Replace the ground cable immediately if lost or damaged!
2.4.6 Spray gun lock
The spray gun must always be secured against
unintended operation, even for the shortest of
work breaks.
Set the safety lever horizontally to secure the
spray gun.
Fig. 7: Spray gun lock
2.4.7 Thermistor-motor protection-trigger
This relay serves to monitor temperature in the agitators’ motors When over-
heating occurs, the agitator will shut down and a fault will be signalised at the
control cabinet.
