6. 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.
6.1. 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 EC
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® (soft-start) module.
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 ow
controls are placed into the cylinder control lines in the “meter out” mode. Flow controls
mounted in this fashion do not operate sufciently when the system is initially being
relled with compressed air after the system has been de-pressurized. This causes
uncontrolled cylinder speed on the rst actuation of the cylinder. The EEZ-ON® (softstart) feature can remedy this situation by gradually relling the system. Thus, allowing
cylinders to ease into place instead of slamming. When using the EEZ-ON® (soft-start)
feature, the time it takes for the outlet pressure to reach approximately 50% of inlet
pressure can be changed by adjusting the ow control in the EEZ-ON® (soft-start)
module. Turning the ow control clockwise will increase the time it takes the outlet
pressure to reach 50% of inlet pressure. Turning the ow control counter-clockwise
will reduce this time. This time interval is directly affected by the volume of the system
being lled. 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® (soft-start)
feature only works when switching the M35 Series valve on. The EEZ-ON® (soft-start)
feature does not affect the exhaust (safety) function of the valve.
6.1.1. Safety Function According to ISO 13849 and EN 692
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
situations and to shut off and prevent further electrical energization of the solenoids.
The control outputs of the safety system must be designed and constructed to meet the
Category and/or Performance Level requirements of the safety system, as determined
by the risk assessment of the machine. Normally, the outputs to the solenoids is a
dual-channel output from a safety relay or safety PLC.
These products are designed and manufactured in accordance with the safety
principles of ISO 13849-1 and EN 692.
6.1.2. Common Cause Failure – CCF
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.
4 www.rosscontrols.com
Page 5
M35 Series Operating Instructions
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.
• Maintain compressed air quality, e.g., ltration, pressure regulation, lubrication.
• Avoid compressor oils that can cause valve seals to swell, soften, or otherwise
deteriorate.
• Operate within prescribed temperature limits.
• Install the valve such that the normal stroke travel of the valve elements are
perpendicular to the main direction of machine vibration and/or mechanical shock.
• Do not use a test pulse longer than allowed by the Technical Specications.
• Avoid external magnetic elds.
• Do not plug the valve exhaust port.
• Use only high-ow, non-clogging silencers, available from ROSS®.
6.1.3. Diagnostic Coverage
A diagnostic coverage of 99% is achievable through appropriate integration of the M35
Series valve into the safety control system. The monitoring system must check for the
proper change of state of each valve pressure sensor (S1 & S2) with each change
of state of the safety control system outputs to the valve solenoids (Sol 1 & Sol 2).
Detection of a fault by the safety control system must trigger a shut-off of the safety
controller’s outputs to the valve solenoids (Sol 1 & Sol 2), see section 8.
6.1.4. Fault Modes
Note that normal operation requires that Sol 1 & Sol 2 be energized simultaneously
for switching the M35 Series valve on, and de-energizing both Sol 1 and Sol 2
simultaneously for switching the M35 Series valve off. Faults that could occur during
normal operation:
Sol 1 & Sol 2 energized simultaneously
S1 ON, S2 OFF
S1 OFF, S2 ON
S1 OFF, S2 OFF
Sol 1 & Sol 2 de-energized simultaneously
S1 ON, S2 OFF
S1 OFF, S2 ON
S1 ON, S2 ON
6.1.5. Foreseeable Misuse
WARNING
Risk of Injury!
Misuse may result in injury or damage.
f The product must be used exclusively as intended.
Foreseeable misuse includes:
• Use outdoors
• Bypassing the safety function or diagnostics
• Failing to utilize the onboard pressure sensors to verify valve operation on every
cycle – energizing and de-energizing
• Allowing continued operation of the valve when one or both valve shifted signals
(from pressure sensors) are not conrmed.
• Use in reverse operation (reversal of supply and exhaust air)
• Operation in low-demand mode per IEC 61508
• Operating at pressures below minimum operating pressure or above maximum
operating pressure.
6.2. Responsibilities of the System Owner
• Observe the information on assembly and operating conditions listed in the

• Switch the valve at least once a month to ensure its proper operation.
• Make sure that the fundamental and proven safety principles in accordance with
ISO 13849 for implementation and operation of the component are complied with.
• Make sure that the permissible switch-on and switch-off pulses for feedback-free
operation of the pneumatic devices are observed.
• If you operate the M35 Series valve together with an electric two-hand control, it
must comply with the EN 574 standard. Selection and installation of this two-hand
control must take place in accordance with the manufacturer’s specications.

M35 Series Operating Instructions
Failure of the valve to shift synchronously leads to a fault in the M35 Series valve.
This could happen for a variety of reasons, such as:
• Defective piston seals,
• Main valve elements experiencing a switching delay due to dirt or resinous oil,
• Insufcient electrical signals to valve solenoids; suitable voltage not available,
• Receipt of signals at solenoids not synchronous,
• Pilot valves experiencing a switching delay due to damaged components, dirt, or
resinous oil,
• Excessive water build-up in the valve.
9. Disconnecting and Removal
CAUTIONS
Risk of injury due to installation while pressurized or with live parts!
Installation while pressurized or with electrical power switched on can result in
injuries due to sudden pressure build-up or electric shock.
f De-energize and de-pressurize the relevant system parts before installing the valves.
f Secure the system to prevent it being switched back on again.
Risk of injury due to disconnecting pressurized or live parts.
• Disconnecting a pneumatic component while the system is pressurized or while
electrical power is supplied can result in injury or death due to sudden pressure
release, unexpected movement, or electric shock.
• Isolate and lock out the electrical and pneumatic systems before disconnecting the valves.
