Are there requirements to have awareness devices like tower lights on our robot cell? I would like to have some lights signal when the robot is in normal operation, Teach Mode, or if there is an error, but I would like a standard to provide to request the capital. Thank you, Holly

I have a question about the doors in the robot cells, are they required to be painted? if yes, in which standard is the requirement settled?

I understand that safeguarding multiple people in the workspace require each have his own enable device. Does that mean, when one enables his device, the other devices will be disabled?

FANUC - "Stop position prediction". Hello, can you tell me what this DCS option is used for? We have a supplier who uses this option on the robot in a fully cage scenario, no collaboration with any human. This option increases the footprint inside of the cell to allow the robot to run at full speed. We want this supplier to not use this option, but they feel it is needed for the safety and to prevent the robot from crashing through the fence in an abnormal situation. Any info on this feature would be greatly appreciated!

When performing the Initial Risk Assessment (according to R15.06), must the safety-rated soft axis and space limiting features of a collaborative robot be excluded from the system?

Fence Guarding: I just purchased a Fanuc M-710ic. I am getting ready to purchase some safety fencing to establish a perimeter around the robot. The fence height I am proposing is 2200 mm (86 inches) tall. What are the standards required for fence height? I would prefer to go shorter because this robot will be in a lab setting for development/training etc... Thanks

Looking for clarification. I understood that a robot cell had to meet a minimum performance requirement of PLd Cat.3. But then I read R15.06-2012 5.4.3 and it says other performance criteria can be used as the result of a comprehensive risk assessment. Is it allowable then to have a lower performance level for a small robot cell that might have a risk assessment that has a PLr of PLc, for example?

I have a robot which will perform welding on a metal part. Parts are loaded by hand onto a carousel which then shuttles the part into the robot operating area and places a solid steel partition between the robot and loader. It is in an enclosure that it accessed for routine maintenance and setup (i.e. changing weld tips or wire) by an interlocked door permitting someone to enter the enclosure to perform these functions. The interlock stops all hazardous movement when the door is opened. The enclosure is not overly large but large enough that someone could stand inside and have the door closed behind them. Is there are requirement that personnel must be detected in this space to prevent the door being closed behind them? If so, can you please provide a reference to this in the standard? Does it make a difference is one can see someone inside (even if it is only from the sides of the enclosure)?

I am a safety specialist and I am trying to find any recommendations/requirements related to a robot brake test and the periodicity of such a check? I know the new KUKA robots come with an installed brake test. I write safety specifications and I am just trying to set some criteria. I would like to do more than just say "comply with the manufacturer's requirements for periiodic brake tests" if possible. Any thoughts or help would be appreciated.

It is permissable to guard a robot using only a laser scanner to detect operator approach and stop movement or is a barrier (such as a fence) required?

Hello, I seem to remember there being an 18 inch requirement in the RIA 15,06 standard between the robot envelope and the cage, but I cannot find it in the 2012 standard. Is this located somewhere else, or am I mistaken. Thank you

Sir or Madam, In using the ANSI/RIA R15.06-2012 to maintain compliance I am constantly running into references to other documents. There is no explanation of the standard just a general "shall be consistent with or meet the requirements of (fill in the blank other standard). In each case, these documents are available at a significant cost. What is the purpose of assembling an all-inclusive guideline for robot integrators if all it does is point me to other documents. Very frustrating.

I'm trying to determine if I need to have a safety rated dump valve or just a regular dump valve for an application. The dump valve is used on a shuttle table. This shuttle table is loaded by the operator, the operator pushes a button, and the table enters the cell at which point the robot unloads the table. The table is enclosed by guarding and a light curtain, so the operator is protected by pinch points. However, when the integrator/tech is teaching the robot in the cell, there may be a scenario where injury could occur. What's your thoughts? Thank you!!

I have a robot cell with a large steel structure inside of it. The robot's workspace is inside of this structure. Access to one side of the structure is needed very rarely (maybe once a year) for maintenance on different parts of the structure. We have put "drop-n-lock" style fencing (requires a tool to lock and unlock the panels) with no movable panels (gates, etc..) on this side. Access to this area is only possible if fence panel(s) are removed. If maintenance/repair is needed, the operator will need to remove a panel (using a tool) to gain access. Is the fact that a tool is needed to do this sufficient? or do the panels that are deemed "removable" for maintenance need to be interlocked?

I am working on safety for input conveyor where operator will feed parts and it will index one position at a time. Position where robot picks the part is inside the fence and I do have light curtain on loading side of conveyor at appropriate distance from robot (1.5 m) gripper but not so far from loading point (500mm). But there are some pinch point at loading side. So will operator process start button with combination of that light curtain would be considered safe enough? That operator run bar has process start confirmation, ESTOP and reset.
