Each configuration consists of a sequence of four numbers, where '1' indicates the LED is on and '0' indicates it is off. Various states such as 'Actuator without power', 'Actuator with power', and 'Actuator with torque limiter activated' are represented by specific LED sequences.
Mounting Instructions: Proper assembly of the mounting kit is crucial for aligning the actuator with its components, such as valves. The mounting holes must comply with ISO 5211 standards, and the female output must conform to DIN 3337. Non-compliance can lead to irregular friction and reduced lifespan of the actuator and valve.
Power Supply and BSR System: In the event of a power outage, the actuator will stop in its current position. If equipped with a BSR system, it will move to a preset safety position. Specifies the behavior for normally open (NO) and normally closed (NC) configurations.
