2 Function and application

Note

The semi-rotary drive with intermediate-position module DRRD-...-PS1 can be

destroyed t hrough incorrec t use.

• Make sure that the intermediate-position module is throttled.

The intermediate-position module DRRD-...-PS1 is intended to permit positioning

of the flanged shaft in half of the nominal rotation angle of the semi-rotary drive

DRRD. This intermediate position can be travelled through.

3 Transport and storage

• Take into account the weight of the semi-rotary drive with intermediate-position

module.

Depending on the design, the DRRD-...-PS1 weights up to 20 kg.

• Transport the DRRD-...-PS1 by grasping the housing. Transporting it by grabbing

the dampeners 1 is not recommended, since the dampeners of the intermedi-

ate position can move axially (no safe stop).

4 Installation

4.1 Installation, mechanical

• Secure the semi-rotary drive at the intended position and the effec tive load to

the drive flange ( Operating instructions DRRD).

4.2 Installation, pneu matic

• Connect tubes to the supply ports ( Fig. 2):

– intermediate position 4

– semi-rotary drive 2 (swivel clockwise)

– semi-rotary drive 3 (swivel anti-clockwise).

Note

Sucked-in c ontamination and fluids disturb the function.

– Keep venting hole 6 clean and dry.

– Do not cover venting hole 6.

Fig. 2

To set the swivel speed at the semi-rotary drive:

• Use one-way flo w control valves in all supply ports:

– for DRRD-16/20 as close as possible to the supply ports

– for DRRD-25 … 50 screwe d directly into the supply ports.

For vertical installation and eccentric loads:

• Use the controlled throttle check valves HGL or an air reservoir VZS.

In this way you can prevent the effective load from sliding down suddenly if

there is a sudden pressure drop.

4.3 Installation, electric

• Place the cylinder switches in the slots aJ to interrogate the intermediate posi-

tion directly at the semi-rotary drive. Slot 8 can be used to interrogate the

intermediate position piston.
