1. Slowly pressurise both supply ports of the semi−rotary drive DRQD. For slow
start−up pressurisation use safety start−up valve type HEL.
2. Screw the flow control screw of the GRLZ at the mid−position module:
ć completely in
ć and then open with one rotation.
3. Pressurise the mid−position module. The semi−rotary drive moves to the preset
mid−position.
4. Vent the mid−position module.
5. Start a test run at low rotational frequency.

DRQD−...−YSRJ exceeds the permissible load of the mid−position (only mass moment
of inertia of DRQD−...−PPVJ permissible).
