1. Short description

The gearbox described here is based on a GS.3 part-turn gearbox. Instead of theoutput drive flange and the coupling, a base flange and a lever are mounted for the"base and lever" version. Typically, a lever arrangement with ball joints is mountedto the lever for valve operation.

Version The first letter of the version indicates the position of the worm shaft in relation tothe worm wheel (view on input shaft).

The second letter indicates the direction of rotation at the output drive (view onhousing cover) for clockwise rotation at the input shaft.

2. Assembly

2.1. Gearbox: mount and secure

Danger of jamming due to moving parts!

→ Prior to mounting, check whether there are no space constraints. The actuatoror other parts must be outside of the lever swivel range.

→ Provide protective equipment.

Modification of lever range caused by vibration!

→ Mount the lever gearbox on a firm, rigid, and vibration-free surface in such away as to prevent any relative movements between the base and the fixingelement.

1. Adjust mounting position to ensure that tube to valve [1] as well as swing leverof gearbox [2] are in parallel.Information: Observe permissible angle deflection between tube and swinglever.

- in the opposite direction as swing lever [2]: max 10°- in the same direction as swing lever [2]: max 3°

2. Thoroughly clean and degrease mounting surfaces.

3. Fasten lever gearbox with 4 screws (quality min. 8.8) and lock washers.

2.2. Lever position: adjust

By re-placing the lever, the lever position may be changed in steps if required.

Information For more precise (adjustable) setting, the lever position can also be changed bychanging the swing angle via the gearbox end stop. Refer to operation instructions.

2.3. Lever arrangement: mount

Ball joints suitable for swing lever including lock nuts and welding nuts are availableon special order with AUMA.

1. Insert ball joint [1] into bore at swing lever [6], fix with crown nut [7] and secureagainst removal using cotter pin [8].

2. Insert the second ball joint [1] into bore at valve lever [5], fix with crown nut [7]and secure against removal using cotter pin [8].

3. Fasten both welding nuts [3] on ball joints [1] until half the thread length.Information: Respect minimum thread engagement (Xmin = 1 x thread diameter).

4. Move lever gearbox and valve into the same end position.5. Ensure that valve lever [5] and swing lever [6] are perpendicular.6. Measure tube length required and shorten the tube to the length needed.7. Unscrew welding nut [3] from both ball joints and weld to the tube.

Information: Apply corrosion protection after welding work.

8. Tighten lock nut [2] and tube [4] into ball joint at swing lever.Information: Respect minimum thread engagement (Xmin = 1 x thread diameter).

9. Remove second ball joint [1] from valve lever [5], tighten lock nut [2] and screwball joint into tube.Information: Respect minimum thread engagement (Xmin = 1 x thread diameter).

10. Insert the second ball joint [1] into valve lever [5], fix with crown nut [7] and se-cure against removal using cotter pin [8].

11. Adjust suitable length by turning the tube.Information: When using the ball joints supplied, one ball joint has aright-handed thread, the other a left-handed thread.

Information: When adjusting the length, make sure that angle α min. or α max.are neither undercut nor exceeded.

3. Technical data

Information The technical data relating to the GS.3 part-turn gearbox type range as well as thesupplement on the version with base and lever (see below) also comprise optionsfurther to the standard version. For detailed information on the customer-specificversion, refer to the order-related data sheet. The technical data sheet can bedownloaded from the Internet at http://www.auma.com in both German and English(please state the order number).

3.1. Features and functions

The gearbox is based on a GS.3 part-turn gearbox. Consequently, the technical dataof GS.3 type range applies. The special features for the base and lever version aredescribed hereafter.
