  • Page 37: Logic Configuration

    Logic configuration The SG-ONE offers 8 types of logic, and by performing the logic configuration procedure listed below, you can enable the desired logic. The SG-ONE can transition to the Configuration state from the Run or Protection state. Configuration operations are disabled in the Initial and Stop states. Once any logic is configured, it is kept in the SG-ONE even if the power is turned off.

  • Page 39: Timer Configuration

    Timer configuration SG-ONE has an OFF-delay timer function that retains the safety outputs during the configured time and after that turns OFF the safety outputs. You can use this function to configure stop category "0" or "1". Perform the configuration procedure listed below to configure the OFF-delay timer to one of the following eight settings, using the same procedure as that for configuring the logic: 0, 0.1, 0.5, 1, 2, 5, 15, or 30 s.

  • Page 41: Cancelling The Protection State

    Cancelling the Protection state SG-ONE transitions to the Protection state if a failure is detected in an external device or an error is detected in external wiring, such as when different operations are performed between dual channel inputs or two muting inputs, or when the EDM input is OFF while the safety outputs are transitioning from OFF to ON by output control.

  • Page 42: Canceling The Stop State

    Canceling the Stop state If the SG-ONE detects any wiring errors, abnormalities or internal circuit failure, it changes to the Stop state and locks out operations. The Stop state can be cancelled by the following method.  Cancellation by removal of power to SG-ONE The Stop state is cancelled by restart of power to SG-ONE after removing the error factor.
