TCF Fellbach (2021).0503/21
Our policy is one of continued research and development. We therefore reserve the right
to amend, without notice, the speciications given in this document.
3. Functional Safety
3.1. General Safety Instructions
Note:
The VP23 is not a design with inherent fail-safe characteristics.
Therefore, no safety-related properties can be guaranteed at valve level.
For machine controls (complex mechatronic systems) with the VP23, a risk analysis
according to e.g. EN-ISO12100 is strongly recommended.
Information on the current standards situation can be obtained from the VDMA or the BGIA.
DANGER - Danger due to hazardous movement
Changes to the valve coniguration can lead to unwanted movements or changes to connected consumers under air supply.
Please establish a safe operating condition before changing the valve coniguration. This also applies
in particular to changes via the USB coniguration interface or the IO-Link parameters.
Use suitable stop and vent valves in the supply lines and at the consumer connections for disconnection.
Warning! - Danger from compressed air
After switching off the pressure supply, port 1 may still be under pressure for a longer period of time.
Protect yourself and others by not removing pressurized connections and wear
appropriate personal protective equipment when working!
Depressurize the system before carrying out any work
Have all work carried out by Pneumatics specialists
Warning! - Clogging of silencers
Blockage of the silencers can lead to malfunction of the valve
Ensure appropriate air purity
Warning! - Risk of injury due to noise
Operate the valve only with suitable silencers
Always wear hearing protection when working
Warning! - Risk of injury due to insuficient qualiication
As the operator, make sure that work is only carried out by qualiied specialist personnel
Train the operating personnel comprehensively in safety issues
Have electrical installations carried out by qualiied electricians only
CAUTION - Risk of burns due to hot surfaces
After longer operating times or at high pressures, considerable heat may be
generated at the solenoid. Danger of burns when touched
