1. Apply operating pressure p1.
2. Switch on the supply voltage. The product runs a self-test for errors.

The product is now ready for operation and can be pressurised.
The valve is tested pneumatically in a self-test once an hour for as long as the product
remains in this status. Operating pressure p1 must be applied; otherwise, the valve switches
to malfunction.
3. Apply Enable signals EN1/EN2. In monitored start operating mode a start signal is also required at
S34 .

Power LED (green) lights.

The outlet pressure p2 is built up slowly.
Duration t of the pressure build-up is adjusted with the flow control screw attached to the
cover. The output pressure rises depending on the flow control setting. When the switch-through
pressure is reached (approx. 50% of operating pressure p1), the valve’s main seat opens
11. The product now pressurises the system at full flow.

Operation
The mechanical system of the product is not tested when it is pressurised.
• Perform a forced switch-off at least once a month if the process-related switching frequency is
lower.
The pause period after exhausting is 2 s. This period must always be complied with. Only then can
pressurisation be repeated.
