3 Prerequisites for Use of the Product
f Make these operating instructions available to the engineer and assembly
technician of the machine/system in which the product will be used.
f Keep these operating instructions during the entire product life cycle.

3. 1 Personnel qualifications

Assembly, installation, commissioning, maintenance, and decommissioning
may only be carried out by qualified personnel that have the required knowledge
of and experience in dealing with electrical and pneumatic control technology.
4 Delivery Contents
The delivery contents include:
• DM valve
• Operating instructions
• 2x blanking plugs for second connection 1+2 (see section „Connecting the
pneumatics and the electrics")
5 Service, Repair and Maintenance
f In case of technical problems or a required repair, please contact your local ROSS
service. If used properly, the DM valves will not require maintenance. Unless
otherwise required, ROSS recommends performing a functional test at least
annually (see 8. 1 „Conducting a function test").
6 Notes on Safety
The product has been manufactured according to the accepted rules of current
technology. Even so, there is a risk of injury or damage if the following safety
instructions and the warnings given in this instruction manual are not observed.

6. 1 Intended use

The type DM2D/DM2F electropneumatic double valves (DM valves) are
safety components in accordance with Machinery Directive 2006/42/EC and
bear the CE marking. Their intended use is to control ventilation and exhaust
in compressed air systems or similar applications, such as the control of
pneumatically actuated clutch-brake combinations of mechanical presses, as well as
to avoid unexpected switch-on and release of energy in pneumatic tubing systems
and end devices in the industry.
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.
6. 1 . 1 Safety function according to ISO 13849 and EN 692
DM valves are self-testing, redundant systems in accordance with the requirements
listed in ISO 13849-1 and -2. Their pneumatic "fail-safe exhaust" safety function
is ensured even in case of a valve failure (e.g. caused by wear, contamination,
or similar).
For the safety function, DM valves feature control technology properties to
category 4/Performance Level e in accordance with ISO 13849-1 and -2, if
integrated correctly into the control system.
All DM valves are equipped with a "Dynamic Monitoring" function (self-contained), a
Memory function (fault memory) and a Reset function.
The product has been engineered and manufactured according to the fundamental
and proven safety principles of ISO 13849-1 and -2 and EN 692.
6. 1 .2 Common Cause Failure – CCF
Common cause failures result in a loss of the safety function as both channels fail
simultaneously in this case.
Apply the following measures to prevent common cause failures:
• Observe the permissible values for vibration and impact loading
• Observe the temperature range
• Observe the compressed air quality as specified in the technical data
• Observe the permissible operating pressure
