The TIGRON in SIL version is a powerful, explosion-proof actuator for highest safety requirements up to SIL 3. It allows flexible configuration and even provides solutions for very complex demands in safety-related applications.
Up to four different safety functions can be configured and their priority freely defined.
Further parameters such as type of seating, tripping torque and overload protection of the safety function can also be set in compliance with the customer’s needs. A timer function protects against pressure surges within the pipeline. The safety functions are controlled and monitored by a safety-related software.

In this video, you will learn how to set the limit switching for TIGRON multi-turn actuators via the stroke in the device menu if the valve cannot be operated. For this, you can determine the suitable setting value for the stroke based on your valve data. On the basis of this value, you can then directly set the end position via the menu.
