5.6 CONTROL ELEMENTS
• SELECTOR 1 POWER-UP MODE: This setting specifies behavior of the element on power up of the relay. When set
to "Restore", the last selector position, stored in non-volatile memory, is restored after powering up the relay. When set
to "Synchronize", the selector sets to the current 3-bit control input after powering up the relay. This operation does not
wait for time-out or the acknowledging input. When powering up, the rest position (0, 0, 0) and the out-of-range 3-bit
control words are also ignored, the output is set to Position 0 (no output operand selected), and an alarm is established
