2.2 Intended use
A valve with IO-Link interface
is a valve with electrical control for use in one and
two-channel safety applications of up to cat. 3, PL d according to EN 13849-1 as
switch-off element for one channel.
Depending on the application and the requirements of work equipment-related
standards according to EN 13849-1, the user must provide appropriate
monitoring/plausibility checks which comply with the required diagnostic
coverage DC
avg
using a higher-level control.
The valve is exclusively intended for integration into a machine or system or to be
assembled with other components to form a machine or system. The product may be
commissioned only if it is integrated in the machine/system for which it is designed.
The technical data indicated in the operating conditions and the performance limits
must be observed.
The valve with IO-Link interface may be used as follows:
• To control position, pressure, force, velocity, pressure differential and flow
When using the device, a higher-level control logic with corresponding I/O
components is required for holistic control of the machine motion sequence and
safety-related monitoring in connection with the valve with IO-Link interface.
The valve may not be used in potentially explosive atmospheres. The product is only
intended for professional use and not for private use.
Intended use includes having read and understood this documentation completely,
especially chapter 2 "Safety instructions".
2.3 Improper use
Any use deviating from the intended use is improper and thus not admissible.
