Sr. No
4.
This time multiplier setting is used to adjust the operating time of the IEC / UK IDMT characteristic.
5.
This time multiplier setting is used to adjust the operating time of the IEEE / US IDMT curves.
6.
This setting determines the type of reset/release characteristics. IDMT applicable for IEEE curves only.
7.
This setting determines the reset/release time for IEEE IDMT characteristic
8.
This setting determines the reset/release time for Definite Time (DT) and all IDMT curve
9.
This setting determines the enabling/disabling of blocking first stage measured earth fault element due to presence of inrush current.
If IN1>1 Blocking and 2nd Harmonic settings are enabled, then (IN1>1) trip command will be blocked in case 2nd harmonics content in
any phase is above the 2ndHarm Thresh. and fundamental current is below I> lift 2H setting . (Set in SYSTEM CONFIG Menu.)
