REU523 To meet the changing safety requirements on the piler side, existing solutions must be reconsidered and sensors adjusted accordingly. Safety standards specify requirements for safe position detection under specific conditions.
What requirements do safety standards specify?
For example, the requirements for safe position detection when the stacker is occupied are specified in the case that the stacker needs to be moved for maintenance or commissioning. The stacker must maintain its position safely or must be able to move at a safe speed. Safe speed shrinks the buffer at the end of the channel.
In this case, what level of performance must be achieved?
The standard solution (i.e., with two different sensors) achieves the higREU523 hest level of PLd performance. By using a safety sensor, the performance level can be increased to PL e. The FBPS 600i, Lloyd’s first secure barcode positioning system, requires only one sensor to detect a secure position. The device is connected to the safety assessment unit (e.g., frequency converter) through two SSI interfaces.
What are the advantages for customers?
Safe location detection can be performed with only one device that meets the requirements of PL e/SIL 3. The device has low space requirements and an error response time of only 10 milliseconds, making it suitable for fast stackers.
Breakdowns, downtime, or unplanned maintenance work are the worst things that can happen in internal logistics. How can smart sensors help improve system availability?
Yes. Even a single system component failure can reduce productivity or lead to a complete shutdown. Efficient condition monitoring enables rapid response and minimizes downtime in internal logistics. For this purpose, additional functions can be incorporated into existing sensors or special sensors can be used.
How does such an efficient condition monitoring system work?REU523
The pollution control and quality scores constitute warning thresholds, at which the sensor is still safe to operate but indicates that intervention is necessary. For example, to ensure that the sensor continues to work properly, its front screen should be cleaned. Or the precise positioning opening of the container changes and must be checked.
