warnings given in this instruction manual are not observed.

2.1. Intended Use

The RSe Series of double valves are safety components designed and manufactured
in accordance with Machinery Directive 2006/42/EC and bear the CE mark. The RSe
Series line of double valves are redundant 3/2 or 5/2 valves that are designed to meet the
needs and requirements of safe air supply/exhaust (3/2 valves) and safe cylinder return
(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.
f See section 10 "Technical Data" for the standards and test values complied with
and adhered to by the product. See the declaration of comformity for product-
relevant EC directives.
The 3/2 RSe 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 3/2 RSe
Series valve is to shut off supply of pneumatic energy and to exhaust any pneumatic
energy from downstream of the valve. Note: The RSe Series valve cannot exhaust
pneumatic energy from downstream of obstructions such as check valves and closed
center function valves.
The 5/2 RSe Series valve is designed to control the direction of air flow 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
RSe Series does this with the same level of control expected of the machine's/system's
safety circuit. The safety function of the RSe Series valve is to return the cylinder/
actuator to its home "safe" position whenever a fault occurs within the valve. Such a
monitoring system must be capable of inhibiting the operation of the valve.
The RSe Series valves are designed for external monitoring for safe, redundant operation
of the valves. The RSe Series valves are constructed of redundant, 3/2 or 5/2 spool type
valves, and have an overall function of a single solenoid pilot-operated, spring return
valve. Each single valve in the RSe Series is equipped with a PNP proximity sensor.
Monitoring both of these sensors on each actuation and de-actuation of the RSe Series
valve provides a diagnostic coverage up to 99%. Monitoring of these sensors is to be
done by an external monitoring system.
2.1.1. Safety Function According to ISO 13849 and EN 692
RSe 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 RSe 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 proximity 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 safety function of the 5/2 RSe 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 RSe 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. Monitoring
of the two proximity 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.
