[Caution]
1) This product has category 3 functionality and therefore the robot’s whole unit cannot be set to category 4.
2) The controller’s internal circuit has polarity. Please adhere to the polarity as detailed in the wiring examples,
particularly for emergency stop button output when using user equipment. Connect the positive side of the
user equipment (24V DC) to the terminal 2 of CNUSR11/12, then connect the emergency stop button (or
contact points) in the user equipment to across the terminals 3 and 4 of CNUSR11/12, and ultimately con
-
nect the negative side (0V DC).
3) When installing a safety relay to use it as an input point of the controller's emergency stop button command,
use a safety relay that is activated by an input from one of the two systems (i.e. Omron’s G9S Series).
4) The emergency stop input detection relay (internal relay) uses the controller’s internal safety relay control.
If the emergency stop input detection relay is switched OFF, emergency stop is detected and the safety
relay is also switched OFF.
5) When connecting emergency stop button output to an external safety relay, please take note of the polarity
and make sure that the electrical current flows in the same direction as indicated by the dotted arrows in the
two places in the diagram. If the polarity is setup incorrectly, this function will not operate correctly. Please
connect the terminal 13 of CNUSR11/12 to 24V.
