3 Information on functional safety
3.1 Attainable safety rating
The product is suitable for use as an element in a safety-related system in accord­
ance with EN ISO 13849-1 up to category 1, performance level (PL) c.
Note
The suitability for certain applications can only be determined in connection with
the assessment of further components of the subsystem.
3.2 Safety functions
The safety functions are:
– safe venting in the downstream piping system and terminals
– prevention of unexpected start-up (pressurisation)
The safety functions are triggered by switching off the power supply at the pilot
solenoid valve. As long as the voltage at the pilot solenoid valve remains switched
off, the connection between ports 2 and 3 is enabled è Fig. 5.
This switching position represents the safe state.
3.3 Operating conditions
– General notes on safe operation è 2 Safety.
– Ambient conditions and additional technical specifications è 13 Technical data.
Note
• Actuate the product at least once per month to ensure the safety function
works properly.
