product or its surroundings if you fail to avoid it.
2. Notes on Safety
The product has been manufactured according to the accepted rules of current
technology.
There is risk of injury or damage if the following safety instructions and warnings given
in this instruction manual are not observed.
2.1. Intended Use
The MCSE Series double valves are safety components designed and manufactured
in accordance with Machinery Directive 2006/42/EC. Its intended use is to control
ventilation and exhaust in compressed air systems or similar applications, as well as
to avoid unexpected switch-on and release of energy in pneumatic tubing systems and
end devices in the industry.
The
MCSE Series double valves are designed for safe, redundant operation and have
internal monitoring. The valves consist of redundant 3/2 valves and have the overall
function of an externally piloted valve with spring return.
f See section 10 “Technical Data” for the standards and test values complied with
and adhered to by the product. See the declaration of conformity for product-
relevant directives.
Intended use includes having read and understood this documentation, especially the
chapter 2 “Notes on safety”
Soft Start
The MCSE Series double valves have a soft start function (soft start). The function of
the soft start module is that the output pressure increases slower than normal during
pressurization, until it reaches approx. 50% of the inlet pressure. The valve then opens
fully at this point and fills the system with the full flow rate. This feature can be used to
reduce the surge of a sudden, quick pressure application of cylinders. This function is
particularly useful when inline flow controllers are placed in the cylinder control lines.
By fully opening the soft start, the soft start function could be disabled if not needed.
2.1.1. Safety Function According to ISO 13849
The MCSE Series safety valve is a redundant system according to the requirements
of ISO 13849-1 and -2, in which the pneumatic safety functions “safe exhaust” and
“prevention of unexpected start-ups” are ensured, including in case of a safety valve
fault (e.g., due to wear).
The safety function of the 3/2 valve from the MCSE Series is that the machine/system
is only supplied with pneumatic energy (compressed air) when the redundant electrical
control and therefore both valve elements are actuated simultaneously. The supply
with compressed air is switched off and the system is exhausted if the redundant
electrical control is not available.
The MCSE safety valve is designed in such a way so that the safe state (filling switch-
off and exhausting the operating line) is always ensured, even in case of a fault within
the valve (e.g., due to wear, contamination or similar situations). The control outputs of
the electrical safety system must be designed and constructed in such a way that they
fulfill the requirements of the category and the performance level (PL) of the safety
system, which result from the machine’s risk assessment. With correct integration in
the control system in accordance with ISO 13849-1 and -2, these products can be
used in up to Category 3 and 4 and a performance level up to e can be achieved.
The product has been engineered and manufactured according to the fundamental
and proven safety principles of ISO 13849-2.
2.1.2. Common Cause Failure – CCF
The product has been engineered and manufactured according to the fundamental
and proven safety principles of ISO 13849-1 and -2 (e.g., measures for the software,
diagnosis, against further CCF, against systematic failures etc.) and then evaluating
whether the necessary performance level has been achieved.
Common Cause Failures (CCF) are failures of different components, resulting from
a single event. CCF are not to be confused with cascading faults or common mode
faults. Common cause failures can cause loss of the safety function, especially in dual
channel circuits where both channels could fail simultaneously due to a single event.
