5.1. Stroke

The stroke of linear thrust units is limited by end stops.

Damage at linear thrust unit due to excessive torques!

→Max. permissible input speeds may not be exceeded.

Approaching the end stops in motor operation!

Risk of damage at linear thrust unit.

→DO NOT use end stops as stroke limitation in motor operation.

→Prior to performing motor operation: Limit stroke via limit switching in multi-turn

actuator (setting).

→Observe overrun when performing the setting.

Stroke setting The stroke per turn depends on the thread pitch of the stem (refer to name plate).

The setting of end positions OPEN and CLOSED within the possible stroke of the

linear thrust unit is done via the mounted multi-turn actuator.Refer to <Limit switching:

set> chapter in operation instructions of suitable AUMA multi-turn actuators.

5.2. Thrust limitation

Thrust limitation is made via mounted actuator.

Refer to <Limit switching: set> chapter in operation instructions of suitable AUMA

multi-turn actuators.

Damage at linear thrust unit due to excessive torque!

→Max. permissible thrusts may not be exceeded.

→Use actuator in recommended size.

→Stall torque operations and operations while bypassing the torque switches are

not permitted.

Valve damage due to excessive tripping torque limit setting!

→The tripping torque must suit the valve.

→Only change the setting with the consent of the valve manufacturer.

Calculation of thrust limitation (tripping torque)

The maximum required or permissible thrust [F in kN) for a globe valve must be

converted to torque [T in Nm] when setting the actuator torque switching:

Formula: T = F x f

LE 200.1LE 100.1LE 70.1LE 50.1LE 25.1LE 12.1Type 4.63.93.93.22.62.6Factor f

The thrust limitation is then performed indirectly using the calculated value through

the setting of the torque switching at the mounted multi-turn actuator.

Example:

Max. permissible thrust of globe valve:F = 30 kN

Linear thrust unit type LE 50.1 (factor f = 3.2)

T = 30 kN x 3.2 m/k = 96 Nm

Multi-turn actuator type SA 10.2; torque range 40 –120 Nm

LE 12.1 –LE 200.1 Commissioning

5.3. Test run

Moving parts!

Danger of jamming.

→Keep hands clear from stroke range of combination.

→If necessary, fit protection cover.

Verify stroke direction Information:AUMA linear thrust units type LE 12.1 –LE 200.1 leave the factory

with retracted stem (end position OPEN).

1. Move actuator manually to intermediate position or to sufficient distance from

end position.

2. Switch on actuator in direction OPEN and observe the direction of stroke.

→Switch off before reaching the end position.

3. In case of incorrect direction of stroke, reverse rotary direction at actuator.

4. Then: Approach end position CLOSED and end position OPEN and check

seating.
