Make sure that the jumper connector is installed correctly. To change the control logic for the FR-A800-GF, remove the control circuit terminal block and change the jumper connector Never change the control logic while power is ON. reinstall the control circuit terminal block securely in place. position. (Refer to page 839 for details on how to remove the terminal block.) After changing the jumper connector position, Sink logic and source logic In the sink logic, a signal turns ON when a current exits from the corresponding signal input terminal. Terminal SD is common to the contact input signals. Terminal SE is common to the open collector output signals.
In the source logic, a signal turns ON when a current enters into the corresponding signal input terminal. Terminal PC is common to the contact input signals. Terminal SE is common to the open collector output signals.
