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 CM26 Series of double valves are safety components designed and manufactured
in accordance with Machinery Directive 2006/42/EC and bear the CE and UKCA mark.
The CM26 Series line of double valves are redundant 5/2 valves that are designed to
meet the needs and requirements of Safe Return
Cylinder/Actuator (5/2 valves) 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.
fSee section 3 “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. The 5/2 CM26 Series valves are designed to control the direction of
airowintoandoutofadouble-actingcylinderorotherpneumaticactuatorin
order to drive the cylinder forward or backward to suit the requirements of the
machine operation. However, the CM26 Series does this with the same level of
control expected of the machine’s system’s safety circuit. The safety function
of the CM26 Series valve is to return the cylinder/actuator to its home “safe”
position whenever a fault occurs within the valve.
NOTE: Maintenance tasks require following full lock-out/tag-out procedures to
relieve hazardous energy and prevent unexpected startup.
2.1.1. Safety Function According to ISO 13849
The CM26 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 5/2 CM26 Series valve is to drive a double-acting cylinder
or other pneumatic actuator forward when the two valve elements are actuated
simultaneously, but to drive the cylinder or other actuator back to its home “safe”
position when both valve elements 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 shutting off causes the CM26 Series valve to supply air
to port 2 of the valve and to simultaneously open port 4 to exhaust (port 5). This, in
turn, causes the cylinder or other actuator to return to its home “safe” position.
In the event of loss of air pressure at the inlet port a check valve (may be removed
oncustomerrequest)isinstalledtotrapthedownstreamair,asmallbleedorice
slowly relieves the trapped air
Attention: There may be some movement because of gravity or pressure balance,
whiletheairwillbeventedviathebleedorice
The CM26 Series valves feature additional Memory (fault memory) and reset
functions.
The CM26 valves are self-testing, redundant systems in accordance with the
requirements listed in ISO 13849-1 and -2.
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 are dual-channel outputs from a safety relay or safety PLC.
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.
Critical failure modes and causes:
• Failure of the safety function - caused by simultaneous incomplete return of both
solenoid valves (A and B).
• 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.
• Maintaincompressedairquality,i.e.,ltration,pressureregulation,.
• Avoid oils that can cause valve seals to swell, soften, or otherwise deteriorate.
• Operating outside of 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Specications.
• Avoidexternalmagneticelds.
• Do not plug the valve exhaust port.
• Useonlyhigh-ow,non-cloggingsilencers,with similarorhigher specications
as ROSS®silencers.
2.1.3. Diagnostic Coverage
A diagnostic coverage of 99% is achievable through appropriate integration of the
CM26 Series valve into the safety control system.
WARNING: In the event of loss of pressure during a fault could cause unexpected
movement of a cylinder that is being controlled by the valve.
2.1.4. Foreseeable Misuse
WARNING
Risk of Injury!
Misuse may result in injury or damage.
fThe product must be used exclusively as intended.

Foreseeable misuse includes:
• Use outdoors
• Bypassing the safety function or diagnostics
• Operation in low-demand mode per IEC 61508
• Operating at pressures below minimum operating pressure or above maximum
operating pressure.
ROSS CONTROLS is not liable for any damages resulting from improper use.
The user alone bears the risks of improper use of the product.
2.2. Responsibilities of the System Owner
• Observe the information on assembly and operating conditions listed in the
operating instructions, or the data sheet.
• Comply with the further requirements of ISO 13849 (e. g., CCF, DC, PLr, software)
if you intend to use the product in higher categories (2 to 4).
• Make sure that the maximum number of switching cycles (B10D) within the service
life TM is not exceeded. If the expected number of switching cycles for a component
exceeds the B10D value during its period of use, suitable replacement intervals have
tobespecied.
• 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 CM26 Series valve together with an electric two-hand control, it
must comply with the ISO 13851 standard. Selection and installation of this two-
handcontrolmusttakeplaceinaccordancewiththemanufacturer’sspecications.
2.3. Safety Instructions
• When implementing surge suppression measures, be sure to check whether or
not this extends the valve shut off response time which could extend the machine
stopping time.
• In case of high levels of machine vibration, use appropriate vibration-reducing
elements when installing the valve.
• Supply the proper voltage - under-/ overvoltage situations can result in solenoid
burnout or failure.
• Make sure that the silencer’s ow capacity is not restricted as this could affect
system performance.
• Ifrequired,replacethesilencerwithamodelequivalentorhigherinspecications
as ROSS®silencers.

due to sudden pressure build-up or electric shock.
fDe-energize and de-pressurize the relevant system parts before installing the valves.
fSecure the system to prevent it being switched back on again.
ATTENTION
Destruction of components!
Chemical substances can damage the surface, the markings and the seals of the device.
fInstall the valve such that it is protected against the effects of chemicals.
Damage to the device through storage at incorrect temperatures!
The ambient temperature represents the permissible storage temperature and depends on
the type of valve in question.
fObserve the temperature information in chapter 3 “Technical Specications.”
5.1. Mechanical Installation
Secure the valve using the through holes in the valve base. Refer to pattern for the
required dimensions, see dimensional drawings on page 4 through 8.
5.2. Pneumatic Installation
5.2.1. Electrically-actuated
CM26 Series Valve for Safe Return Cylinder/Actuator – Connect the compressed
air supply to port 1, connect ports 2 & 4 to the pneumatic actuator, port 3 and
5 are the exhaust ports.
5.2.2. Pneumatically-actuated
CM26 Series Valve for Safe Return Cylinder/Actuator – Connect the pneumatic
pilot signals to the signal ports, the compressed air supply to port 1, connect
ports 2 & 4 to the pneumatic actuator, port 3 and 5 are the exhaust ports. Signal
ports 1 & 2 needs to be connected to the outputs of the two-hand control or
the outputs of other valves used to control the CM26. The control valves shall
be 3/2 NC valves.
Reset Port (RESET)
If your valve is not equipped with a reset solenoid on the valve, then the RESET
port should be supplied, externally, from a 3/2 normally closed valve. Reset
signals must be momentary.
5.3. Electrical Connections
Valve Basic Size 0: Electrical connections to the solenoids are made with EN
175301-803 Form C receptacles on the valve.
Valve Basic Size 2: Electrical connections to the solenoids are made with EN
175301-803 Form A receptacles on the valve.
The cables and cable connections as well as the electrical control for the double
valves must comply with the applicable safety regulations.

6.1. Test Procedure
For pneumatically actuated version: Solenoid = Signal Port
6.1.2. CM26 Valves for Safe Return Cylinder/Actuator Application
1. Solenoid A energized – Valve is faulted, port 2 is pressurized, port 4 is exhausted
through the built-in silencer. Status-indicator feedback has to change
2. Reset valve by de-energizing both solenoids and energizing the reset solenoid –
Valve is off, port 2 is pressurized, port 4 is exhausted Status-indicator feedback
has to change
3. Solenoid B energized – Valve is faulted, port 2 is pressurized, port 4 is exhausted
through the built-in silencer. Status-indicator feedback has to change
4. Reset valve by de-energizing both solenoids and energizing the reset solenoid
– Valve is off, port 2 is pressurized, port 4 is exhausted . Status-indicator
feedback has to change
5. Solenoids A & B energized – Valve is on, port 4 is pressurized, port 2 is
exhausted through port 3. Status-indicator feedback is not changing
6. Solenoids A & B de-energized – Valve is off, port 2 is pressurized, port 4 is
exhausted. Status-indicator feedback is not changing
Failure of the valve to shift not synchronously leads to a fault in the CM26 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,
• Insufcient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.
