Safety Output products are crucial when designing a reliable safety system that requires redundancy and monitoring capabilities.
Today’s manufacturers are under pressure to be more flexible, reduce downtime, increase efficiency and, above all, keep personnel safe. These efforts are complicated by yet another requirement: the successful management of external influences. These factors are difficult to predict, and when their true effects become known, effective adaptation can be a challenge. Fortunately, the right machine safety technology can help companies reduce the impact of unforeseen events and keep productivity levels high. In this white paper, we’ll examine how this works, with a focus on key features of machine safety solutions provided by Omron.
When Kerry Foods set out to meet CAN/CSA Z434 for their palletizing robot cell, it turned to Omron. Our successful solution included:
There are 3 major types of machine guarding equipment:
Monitoring the position of a door or guard is a key element in machine safety. There are 3 major types of door switches:
CIP Safety (Common Industrial Protocol Safety) is an extension added to the CIP application layer to provide safety services on CIP-based networks such as DeviceNet and EtherNet/IP. The protocol has been developed according to IEC61508 and ISO 13849:1 and is approved by an independent Notified Body (TÜV).
CIP Safety over EtherNet/IP provides a scalable, modular, network-independent safety protocol that supports multicast messaging for faster response and ensures transmission integrity by detecting errors and allowing devices to take appropriate actions. This protocol is commonly used in systems where there is a need to integrate safety devices from different manufacturers to a single platform, like robots and encoders, to develop a safety solution while reducing wiring efforts.
A forcibly guided relay has a forced guided mechanism that prevents that normally open and normally closed contacts are closed simultaneously. This mechanical link between contact pairs is guaranteed over the whole lifetime. Thanks to this feature, it provides an easy way to design circuits with self- monitoring capabilities, according to international safety standards.
Selecting a specific light curtain size to use can present an unusual challenge in ordering components for a machine. Light curtains are built to a specific height and resolution; as a result, the light curtain has to be very carefully matched to the guarding area to create a safe setup that has no chance of being circumvented.
Before selecting a specific light curtain, you should collect measurements of the space where the light curtain will be mounted – both the width and the height of the opening and will be important.
The width of the opening will correspond to the range of the light curtain, and different light curtains will have different effective ranges, possibly even within a single light curtain series. Light curtains with smaller resolutions tend to have shorter effective ranges, and some light curtains may have separate part numbers or different configuration modes for different ranges. Make sure that the light curtain has a larger range specification than the total width the curtain will cover, and bear in mind that using mirrors or similar devices typically decreases the range as well.
The height of the light curtain will correspond to the height of the opening. The optimum light curtain setup will fully cover the opening and prevent anyone from reaching over, under, or around the light curtain, and will also avoid being too large which will only expose the light curtain to potential damage. A light curtain will have two height specifications that are frequently confused with each other; protection height and physical height. The protection height is the area that the light curtain can safely detect, and should be used for selecting a light curtain rather than the physical height, which is the literal measured length of the light curtain components. Select the curtain smallest available light curtain that has a larger protection height than the height of the opening.
One should keep in mind that a light curtain setup might need additional guarding to cover any gaps in the detection. These gaps are frequently referred to as dead zones, and are caused by a number of factors. Some light curtains do not have transmitters and receiver elements that actually run the entire length of the light curtain. If this is the case, the physical height of the light curtains will be larger than the protection area and some additional hard guarding may be required. Brackets, cables, and connectors can have a similar effect.
