The position of the switch, and therefore the operating mode, is read by the product on energization.

If the switch is set to an unacceptable position, the product detects a fault, the output relay stays open, and the LEDs flash to signal the position error.

If the switch position is changed while the device is operating, all the LEDs flash, but the product continues to operate normally with the function selected at the time of energization preceding the change of position.

The LEDs return to their normal state if the switch is returned to the original position selected prior to the last energization.
