What Are The Most Common Types of Machine Guarding Equipment?
There are 3 major types of machine guarding equipment:
Safety Door Switches — These are required when a machine has a movable guard as access to the dangerous area. Monitoring the door will allow shut off the power when the guard is open or removed.
Electro-sensitive protective device**(ESPE)** — These detect a presence in their protected field and doesn’t require any action from the machine operator. There are different types of devices as safety light curtains and safety scanners.
Pressure-sensitive machine safeguarding products — These include safety mats, edge, and bumpers.
What are the Different Types of Safety Switches and What are They Used For?
Monitoring the position of a door or guard is a key element in machine safety. There are 3 major types of door switches:
Tongue-operated Interlocks — These require a dedicated tongue and can prevent easy cheating of the switch.
Guard Locking Interlocks — These prevent workers from entering in hazardous machine areas. They detect whether or not fences or doors are not opened and, if opened, stop machines before operators are injured.
Non-Contact Door Switches — This type does not utilize the mechanical operating method as opposed to the cam operated and/or tongue-actuated switches. As a result, they are unlikely to suffer from the mounting limitation compared to the other switches because of the easy positioning during installation.
What is CIP Safety over EtherNet/IP?
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.
What is a Forcibly Guided Relay and Where Is It Used?
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.
How to Size a Light Curtain
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.
