<Wiring example 4>: Connect the controller to the safety relay
Use the controller's emergency stop button to input safety relay.
[Caution]
1) Setup a safety relay on the user equipment, and when using to input the emergency stop button on the control-
ler, please only use a safety relay that functions when connecting the input to the one end of the 2 systems (i.e.
QS90SR2SP (Manufacture: Mitsubishi Electric Corporation)).
2) When connecting emergency stop button output to an exterior 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 3
and 10 terminal of CNUSR11 connector to 24V.
