2.1 Intended use
Misuse
2.2 General dangers
This section provides an overview of all major safety as-
pects for the protection of people and for safe, fault-free
operation. Further task-related safety notices appear in
the sections on transportation, installation, checks before
initial operation, and maintenance.
SCSQ10 safety valves are used to control hazardous
movements in pneumatic safety systems with category
4 control requirements per ISO 13849-1 with performance
level “e”. The safety valves are free of residual pressure and
are dynamically self-monitored.
Silencers shall not impair the operation of the soft start /
quick exhaust valve.
WARNING!
Dangerous if misused!
• Incorrect use of safety values can create
dangerous situations.
• Do not use in explosive areas.
• Provide noise reduction measures.
• Never dismantle safety valves, or remove or
replace individual parts.
The following section lists residual risks which
may be present even if the safety valves are used
correctly.

Hazardous movements
Hot surfaces
DANGER!
Danger of death caused by hazardous
movements!
When the power is switched off or if there is a
power cut the loads supported by the safety
valves can drop and the system can lose pres-
sure. This can cause serious injuries.
• Provide additional mechanical safety de-
vices that prevent hazardous movements
after the power is switched off.
WARNING!
Danger of injury caused by hot surfaces!
The safety valves can become very hot during
operation. Skin contact with hot surfaces
causes severe burns.
• When working near hot surfaces, always
wear heat-resistant protective clothes and
protective gloves.
• Before you start any work, make sure that
all surfaces have cooled to ambient tem-
perature.

WARNING!
Danger of injury caused by noise!
The noise level that occurs can seriously damage
your hearing.
• Always wear ear protection when working.
• Fit noise reduction measures, e.g. silencers,
during installation
WARNING!
Danger of injury caused by compressed air!
Compressed air can cause injuries if not handled
correctly.
• Ensure systems are depressurised before
work begins.
• Have all work carried out by pneumatics
specialists.

WARNING!
Danger of injury caused by lack of training!
People who lack proper training cannot assess
the risks when handling the safety valves and
they place others at risk of serious injury or death.
• Have all work on the pneumatic system car-
ried out by pneumatics specialists.
• Have all electrical installation work carried out
by qualiied electricians.
Pneumatics specialists are trained for the specialist area
they work in, and they know the relevant standards and
regulations.
Because of their special training and experience, pneumat-
ics specialists can carry out work on pneumatic, electro-
pneumatic and mechatronic systems and identify and
avoid risks by themselves.
Because of their specialist training, knowledge and ex-
perience, and their knowledge of the relevant standards
and regulations, qualiied electricians are able to carry
out work on electrical installations and identify and avoid
possible risks by themselves.
Qualiied electricians are specially trained for the area
they work in, and they know the relevant standards and
regulations.

2.4 Personal protective
equipment
For all work, always wear:
For special activities,
wear:
2.5 Log book
While carrying out work of various kinds on and with the
safety valves, personnel must wear personal protective
equipment which is referred to in the individual sections in
these instructions.
Protective clothing
Protective clothes are heat-resistant and close-it-
ting clothes with low tear strength, close-itting
sleeves and without any parts sticking out.
Safety shoes
Safety shoes protect the feet from crushing,
falling parts and slipping on slippery surfaces.
Protective gloves
Protective gloves protect the hands and fore-
arms against contact heat if they touch hot
surfaces.
Safety goggles
Safety goggles protect the eyes from lying ob-
jects and splashing liquids.
Ear protection
Ear protection protects your hearing from dam-
age caused by exposure to noise.
To comply with legal requirements, a log book must be
kept of all activities involving the safety valves.

Home position
The working connection
2 (A) is vented via connec-
tion 3 (R). Pressure connec-
tion 1 (P) is closed
Schaltstellung
Switched position
The solenoids in the safety
valve are actuated simul-
taneously.
Working connection 2 (A) is
connected to the pressure
connection 1 (P).
The valve systems monitor
themselves for correct op-
eration with every switch-
ing procedure (dynamic
monitoring).
Faulty switching
The solenoids are actuated
with a time difference
> 0.5s.
The dynamic monitor-
ing system detects the
delayed actuation and
prevents pressure build-up
at the working connection
2 (A).
4 Design and function
4.1 Electropneumatic
actuated
The safety valve with starting function is characterised by
a pressure build-up of the outlet pressure in two phases.
In phase 1, there is initially a slower pressure build-up,
which increases steadily depending on the throttle valve
position and the volume to be illed.
In phase 2, upon reaching a certain pressure, the sequence
valve irst opens and then interconnects the full operating
pressure at the valve outlet of the safety valve. The so-
called gating pressure in this valve design depends on the
operating pressure and is determined by the sequence
valve with the piston area ratio of about 2:1

5 Transport and
storage
Transport
Packaging and storage
Individual packed items are packed according to the ex-
pected transportation conditions.
Packaging is intended to protect the individual compo-
nents against transportation damage, corrosion and other
damage until they are installed. So don’t destroy the pack-
aging and only remove it just before installation.
Check package on delivery to make sure it is com-
plete and has not been damaged in transit.
During transportation:
• Do not drop packaged units.
• Do not throw packaged units.
The safety valves are packed for immediate installation
upon delivery.
If they are going to be stored for extended periods, please:
• Leave the packed units in the box they wereshipped in.
• Do not store them outdoors.
• Store them in a dry, dust-free place.
• Don’t expose them to aggressive media, such as salty air.
• Protect them from direct sunlight.
• Storage temperature: 15 to 35 °C.
• Relative humidity: 90% max.

6 Installation
Before installation,
please note
6.1 Pneumatic connection
Improper
pneumatic connection
• Create a safety zone around the hazardous area in
accordance with the risk assessment for the machine
or equipment.
• For new systems, ensure that connections and lines are
deburred.
• Do not remove blanking covers from the safety valves
until just before installation.
DANGER!
Danger of injury caused by improper
connection!
Faulty pneumatic connections can impair the
safe operation of the safety valves and may
cause severe injuries during operation.
• Use additional safety equipment if
necessary.
• Pipe cross-section corresponding to thr
required design low rate.
• Make sure that any noise reduction
measures that are itted do not impair the
functioning of the safety valve.
• Basically the EN ISO 4414 to be considered.

WARNING!
Danger of injury caused by compressed air!
Compressed air can cause injuries if not handled
correctly.
• Make sure the machine is depressurised
before work begins.
• Have all work carried out by pneumatics
specialists.
Personnel:
• Pneumatics specialist
Protective equipment:
• Safety goggles
• Protective gloves
CAUTION!
Avoid damaging the thread when removing
the blanking covers.
1. Carefully remove the blanking covers from the safety
valve.
2. Fit any additional safety equipment such as failure indi-
cator units in accordance with the separate instructions.
3. Connect air supply equipment for drying, iltering and
lubricating air before pressure connection P.
For requirements for operating media and consumables,
see section 3.7.
Lubrication is not necessary if the connected
load is suitable for oil-free operation.

4. Use only the original silencer (3). Only with
the safety-silencer a residual pressure-free
ventilation is ensured.
5. Connect supply line to the pressure con-
nection 1 (P) in accordance with section 3
Speciications.
6. Connect safety valve to the load. The dis-
tance between the valve and load should be
kept as small as possible.
7. Securely bolt the safety valves to the frame
or machine base via the mounting holes.
8. Fit and seal pipes and hose connections to
the valve and from the valve to the load,
following national standards and regulations
as applicable.
An airtight compressed air system helps
to save energy, which protects the environ-
ment.
