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 M35 Series of double valves are safety components designed and manufactured
in accordance with Machinery Directive 2006/42/EC and bear the CE mark. The
M35 Series double valves are redundant 3/2 valves that are designed to meet the
needs and requirements of safe air supply/exhaust applications for machinery with
pneumatic controls. Typically, these valves are implemented to meet the Category 4
and/or Performance Level e requirements of a machine's (or system's) safety circuit
as determined by a risk assessment of the hazards and tasks required of employees
that interact with the machine/system.
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 CE directives.
The M35 Series valve is designed to supply air to a zone or entire machine/system
until signaled to shut off and exhaust residual downstream pneumatic energy from the
machine. Thus, reducing the hazards associated with the presence of residual energy
during employee access and/or minor servicing. The safety function of the M35 Series
valve is to shut off supply of pneumatic energy and to exhaust any pneumatic energy
from downstream of the valve.
Note: The M35 Series valve cannot exhaust pneumatic energy from downstream of
obstructions such as check valves and closed center function valves.
The M35 Series valves are designed for external monitoring for safe, redundant
operation. The M35 Series valves are constructed of redundant, 3/2 poppet type
valves, and have an overall function of a single solenoid pilot-operated, spring return
valve. Each valve element in the M35 Series is equipped with a solid state pressure
sensor. Monitoring both of these sensors on each actuation and de-actuation of the
M35 Series valve provides a diagnostic coverage up to 99%. Monitoring of these
sensors is to be done by an external monitoring system.
The M35 Series valves can also be purchased with an EEZ-ON
The function of the EEZ-ON
®
(soft-start) module is to, on energization, allow outlet
pressure to increase at a slower than normal rate until it reaches approximately
50% of inlet pressure, at which point the valve will then open fully to finish filling the
system at full flow rate. This feature can be used to lessen the shock of sudden,
rapid pressurization of cylinders. This feature is especially useful where inline flow
controls are placed into the cylinder control lines in the "meter out" mode. Flow controls
mounted in this fashion do not operate sufficiently when the system is initially being
refilled with compressed air after the system has been de-pressurized. This causes
uncontrolled cylinder speed on the first actuation of the cylinder. The EEZ-ON
start) feature can remedy this situation by gradually refilling the system. Thus, allowing
cylinders to ease into place instead of slamming. When using the EEZ-ON
feature, the time it takes for the outlet pressure to reach approximately 50% of inlet
pressure can be changed by adjusting the flow control in the EEZ-ON
module. Turning the flow control clockwise will increase the time it takes the outlet
pressure to reach 50% of inlet pressure. Turning the flow control counter-clockwise
will reduce this time. This time interval is directly affected by the volume of the system
being filled. In larger volume systems the time to reach 50% will be longer than in
systems with smaller volumes. It is important to note that the EEZ-ON
feature only works when switching the M35 Series valve on. The EEZ-ON
feature does not affect the exhaust (safety) function of the valve.
2.1.1. Safety Function According to ISO 13849
M35 Series valves are designed in accordance with the requirements listed in ISO
13849-1 and -2. Their "fail-to-safe" safety function is ensured even in case of a fault
within the valve (e.g., caused by wear, contamination, or similar situations).
The safety function of the 3/2 M35 Series valve is to only supply compressed air
(pneumatic energy) to the machine/system when the two valve elements are actuated
simultaneously, but to shut-off the supply and to exhaust any downstream compressed
air when both valves are shut off or if only one of the two valves is actuated. A fault in
the system where only one valve actuates when switching on or only one de-actuates
when switching off prevents air from being supplied downstream and simultaneously
exhausts any air that is already downstream. Monitoring of the two pressure sensors
by the user's external safety monitoring system makes it possible to detect these fault
