†Note: The presence of ‘EF1’ and ‘EF1PU’ signals depends on the operation characteristic
defined with setting [EF1_Timer], as shown in Table 2.16-5.

1 : A pick-up signal is generated instantly when the element operates.
○
2 : No signal due that the PU element is killed. Use ‘EF1’ in place of this.
○
3 : A pick-up signal is generated, but delayed with the IDMT characteristic.
○
4 : A pick-up signal is generated instantly.
