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 mode of operation 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 throttle setting . When the switch-through pressure is
reached (approx. 50% of operating pressure p1), the valve’s main seat opens

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.
