6.2 Storage

Damage to the safety valve due to incorrect storage!
Unfavorable storage conditions can result in corrosion and material deteriora-
tion. The maximum storage period is two years.
1. Only store the safety valve in dry, cool, and corrosion-proof environments.
Avoid direct sunlight.
2. Keep the safety valve in the original or delivery packaging if you do not in-
stall it immediately.
3. Never use a safety valve that has been stored for longer than two years.

7 Assembly

Danger of injury due to installation of the product while the system is run-
ning!
Installation of the product into a system while it is running can cause major in-
juries from moving parts.
Bring the system into a state in which working movements are no longer
u
possible. Wait until all moving machine parts are standing still, and protect
the system from being switched on.
Danger of injury due to suspended useful loads!
Useful loads that are kept suspended by compressed air pose a danger if they
are not secured before the pressure is switched off in the system.
1. Guide the payloads into a safe position or remove them from the system.
2. You may only then switch off the pressure in the relevant section of the sys-
tem.
The following must be noted during installation:
• The safety valve is packaged to protect it from contamination.
Do not remove the packaging until just before assembling the safety valve.
u
• All compressed air connections and control elements must remain freely ac-
cessible after installation.
• The safety valve must be attached in such a way that it cannot be loosened by
jolts, vibrations, or the like.
Make sure that the safety valve is only used as described in the "Intended use"
u
chapter.

7.1 Preparing for assembly

Prepare for assembly as follows:
1. Stop system operation and protect it from being switched on.
2. Return all suspended loads to a statically secure position or remove them
from the system.
3. If required, exhaust stored compressed air from system parts in the immedi-
ate work area.
4. Make sure the relevant section of the system is without pressure or voltage
and protect it from being switched on.
5. Secure self-turning or other movable system parts before starting assembly
and installation.
6. Let the AS3-SV safety valve acclimatize itself for several hours before installa-
tion, otherwise water may condense in the housing.

7.2 Mount the valve

To mount a single valve:
See Fig. 4.
u
To mount the valve as part of a maintenance unit:
See Fig. 5.
u
The valve must be mounted on both sides with one mounting element each
on the mounting surface.

7.3 Mount the pressure sensor or pressure gauge (optional)

A pressure gauge or electronic pressure sensor can be connected to the thread
connection (8), see Fig. 2, once the blanking plug has been removed.
Observe the mounting instructions enclosed with the components.

7.4 Connect pneumatic connections

Requirement:
The supply pressure must always be between 2 bar and 10 bar.
The correct function of the AS3-SV safety valve is not guaranteed if the
supply pressure is lower than 2 bar.
1. Connect the pressure line for the supply pressure to connection 1 (1, IN).
2. Connect the operating line to connection 2 (2, OUT).

7.5 Connect electrical connections

Connect the supply voltage to plug XPS, the signal output, and, if applicable,
u
start signal X2. The assignment of the XPS plug is the same for all versions.
The contacts on the XPS plug, M12 male have the following pin assignment:
XPS Pin Function
1 24 V DC supply voltage for the device
24 V DC
1
2 Signal contact 42, potential-free
42
2
0V GND
3 0 V
3
X2
4
4 Input for start X2
41
5
5 Signal contact 41, potential-free
Connect the safety signals to control the device to plug X2D. Observe the dif-
u
ferent assignment of plugs for different devices. The type of device can be
taken from the name plate.

7.5.1 Connecting the supply voltage

Danger of injury!
Electric shock due to incorrect power pack!
1. Use a 24 V DC SELV or PELV circuit in accordance with DIN EN 60204-1 to
connect the power supply for the valve.
2. The PELV power source must be a safety isolation transformer in accor-
dance with IEC 61558-1 or IEC 61558-2-6, or a power source offering the
same degree of safety as a safety isolation transformer.
3. Make sure that the power source for the SELV power pack adheres to
DIN EN 60950.
We recommend using a type Z circuit breaker (max. 2 A) or a micro-
fuse (max. 1 A, inactive) to maintain the operating voltage.

7.5.2 Connect the signal contact

The device has a potential-free signal contact (relays 41, 42).
The contact is closed when
• power supply (pin 1+24V / pin 3 0V) is present,
• the self-test (duration approx. 1.5 s) was completed without errors,
• the internal valves are in the positions required by the inputs (start X2 / safety
inputs 1 and 2),
• the green RUN LED is illuminated,
• the red ERR LED is not illuminated.
The pressure at the input is not monitored.
This signal contact can be used, for example, to achieve a loop covering all safety
modules, i.e. an active signal indicates that all safety modules in the chain do not
report an error. The maximum voltage for the signal output is 24 V DC, and the
maximum current is 0.2 A.
