Presence Sensing Device
The above mentioned safeguard interlock is a type of presence sensing device since
it indicates the possibility of somebody being inside the safeguard system. When
separately installing a presence sensing device, however, perform a satisfactory risk
assessment and pay thorough attention to its dependability.
Here are precautions that should be noted:
- Design the system so that when the presence sensing device is not activated
or a dangerous situation still exists that no personnel can go inside the
safeguard area or place their hands inside it.
- Design the presence sensing device so that regardless of the situation the
system operates safely.
- If the Manipulator
stops operating when the presence sensing device is
activated, it is necessary to ensure that it does not start again until the
detected object has been removed. Make sure that the Manipulator cannot
automatically restart.
Resetting the Safeguard
Ensure that the robot system can only be restarted through careful operation from
outside the safeguarded system. The Manipulator will never restart simply by
resetting the safeguard interlock switch. Apply this concept to the interlock gates
and presence sensing devices for the entire system.
Manipulator Operation Panel
When using the Manipulator operation panel, it must be installed so as to operate
the robot system from outside the safeguard.
