5.2 Function
The product is a safe, redundant mechatronic system in accordance with the requirements of EN ISO
13849-1+2. The safe venting pneumatic safety function is guaranteed even in the event of an error in
the valve (e.g. due to wear or contamination). Through its electrical connection (NECA multi-pin plug
socket Sub-D, 9-pin), the product receives secure enable signals (EN1/EN2) from commercially-avail-
able electronic or electromechanical safety relay units, which monitor the machine’s protective
devices (e.g. emergency stop, light curtain, electric door switch on the protective housing, etc.).
The impulse generated by the start button must be within a time-frame of 0.1 s and 2 s.
If the start button is held down for too long or is locked down, the system identifies a cross circuit and
the product is placed in fault mode.
The start signal for S34 must not be generated until 1 s after the enable signals EN1/EN2 are gener-
ated.
If the start signal is generated before or simultaneously with the enable signals, it will not be recog-
nised and must be generated again.

The clock outputs of different controller manufacturers are not standardised. The usability must be
checked in every case. If the clock pulse is outside the described limits, this is recognised by the
product as an error and a safe switch-off is carried out.
The multi-pin plug socket NECA-S1G9-P9-MP3 is intended for conventional circuitry with electromech-
anical safety relays. If problems arise in use with bipolar semiconductor outputs, use the multi-pin
plug socket NECA-S1G9-P9-MP5.
The time delay t2 between EN1 and EN2 must be automatically defined. The duration of the delay is
not evaluated. The multi-pin plug socket NECA-MP5 does not enable the product to detect shorts
across contacts.
Signal contact
The signal contact is a potential-free N/O contact of a semiconductor relay. The contact can be picked
up in the feedback circuit of a safety control system through terminals 3 and 4 of the NECA multi-pin
plug socket as required.
NOTICE!
If the signal contact is operated outside the permitted technical data, this will cause irreparable fail-
ure. Compliance with the specification must be ensured through an appropriate protective circuit.
NOTICE!
Assignment of these contacts is not required to achieve the safety category.

multi-pin plug socket NECA-S1G9-P9-MP3/MP5 è Fig.23.
Example:
At an operating pressure of p1 = 4 bar with reference to the approved tolerance of ± 20% a switch-
through pressure of 1.2 to 2.8 bar is permissible.

NOTICE!
The electro-pneumatic soft-start/quick exhaust valve has control technology features which enable
performance level e to be reached for the safety functions. This product has been designed and manu-
factured in accordance with the fundamental and reliable safety principles of EN ISO 13849-2.
The following requirements apply to the manager:
– Specifications on mounting and operating conditions in these operating instructions must be
observed.
– For use in higher categories (2 to 4), the requirements of EN ISO 13849, e.g. CCF, must be con-
sidered.
– The basic and proven safety principles of EN ISO 13849-2 relating to implementation and opera-
tion of the component must be satisfied.
– When using this product in machines or systems subject to specific C standards, it must be in
compliance with the requirements specified in the standards.
– Before using the product, a risk assessment in accordance with EN ISO 12100 as specified in the
EC Machinery Directive 2006/42/EG, appendix I, paragraph 1 and 1.1.2 is required.
– The user is responsible for coordinating all applicable safety regulations and rules with the com-
petent authority and for compliance with regulations and rules.
Failures due to a common cause (Common Cause Failure – CCF)
The following measures ensure that common cause failures are avoided:
– Compliance with the permissible values for vibration and shock stress
– Compliance with the temperature range
– Compliance with compressed air quality as specified in the technical data, in particular avoiding
flash rust particles (such as caused by servicing work) as well as compliance with the residual oil
content of max. 0.1 mg/m3 when using ester-containing oils (which may, for example, be con-
tained in the compressor oil)
– Compliance with the maximum operating pressure, if necessary with a pressure-relief valve
– Clogging of the silencer must be avoided .
PFHd value
The PFHd value depends on the model of the product and the annual actuation rate (nop).
6 Assembly
6.1 Requirement
– Take appropriate measures to remove any particles in the supply lines.
6.2 Preparation
NOTICE!
In order to ensure electromagnetic compatibility in accordance with the EMC Directive, note the follow-
ing:
• Ensure a wall clearance of 32 mm, e.g. with the MS6-WPB mounting bracket.
• Do not lay cables between the wall and the product.
NOTICE!
Fig. 13 Installation
– Observe the flow direction 1 to 2. The numerals 1 on the product housing serve as orientation.
Fig. 15 Assembly
1. Slide the cover cap MS6-END 1 upwards and remove it.
2. Insert a seal 2 between the individual devices (module connector MS6-MV in scope of delivery).
3. Place module connector 2 in the slots of the individual devices.
4. Fasten the module connector with two screws (product scope of delivery). Tightening torque: max-
imum1.2 Nm.
7 Installation
7.1 Pneumatic Installation
Port 1 and 2
If using screw connectors:
– Note the screw-in depth of the connector thread: 10 mm.
– Make sure that the compressed air lines are connected correctly.
– Screw the connectors into the pneumatic connections using a suitable sealing material.
Connection 3
NOTICE!
The product may only be used with the approved NECA multi-pin plug sockets NECA-... .
Information on terminal connections can be found in the assembly instructions enclosed with the
multi-pin plug socket.
When mounting the multi-pin plug sockets NECA-... with enclosed seal, note the correct position of the
plug with reference to the valve. The display window of the multi-pin plug socket NECA-... must point
forward.
8 Commissioning
For easier commissioning, we recommend planning a reset button (normally closed) in the power sup-
ply circuit. This simplifies a reset in case of error.
The valve is tested pneumatically in a self-test once an hour for as long as the product
remains in this status. Operating pressure p1 must be applied; otherwise, the valve switches
to malfunction.
3. Apply Enable signals EN1/EN2. In monitored start mode of operation a start signal is also required
at S34 .
– Power LED (green) lights.
– The outlet pressure p2 is built up slowly.
Duration t of the pressure build-up is adjusted with the flow control screw attached to the cover.
The output pressure rises depending on the throttle setting . When the switch-through pressure is
reached (approx. 50% of operating pressure p1), the valve’s main seat opens è Fig.11. The
product now pressurises the system at full flow.
9 Operation
The pause period after exhausting is 2 s. This period must always be complied with. Only then can
pressurisation be repeated.

NOTICE!
• Pulses at inputs EN1 and EN2 from 0 to 24 V, of £ 3 ms duration do not send an error message to
the product.
• Pulses at inputs EN1 and EN2 from 24 to 0 V, of £ 12 ms duration do not send an error message to
the product.
The following diagrams shows the exact switching characteristics of the Enable signals EN1 and EN2
with time offset. The maximum reaction time can be derived from the delay between the two signals.
Runtime performance
t1 > 5 ms: Level of EN2/EN1 must be HIGH for min. 5 ms (debounce time/input filter/stabil-
isation time).
t2 < = 75 ms: maximum permissible delay time between EN1 and EN2. If exceeded, the product
is not pressurised and an error message is output.
t3 > = 15 ms: Level of EN2/EN1 must be LOW for min. 15 ms (debounce time/input filter/sta-
bilisation time).
t4 = 2 ms: maximum internal time delay caused by the program sequence.

tp2 } 3: Exhausting > 1 s
Tab. 14 Runtime performance
Maximum reaction time from exhausting to pressurisation: t2 + t1 + t4 = 75ms + 5ms + 2ms = 82ms
