7-18
P253/EN M/C
Sr. No
Parameter
Default setting
Setting Range
3.
IN2>3 Time Delay
1 S
0 to 200s step 0.01s
This setting determines the time-delay for the definite time setting if selected for third stage of derived earth fault element.
4.
IN2>3 TMS
1
0.025 to 1.2 step 0.005
This time multiplier setting is used to adjust the operating time of the IEC/UK IDMT characteristic.
5.
IN2>3 Time Dial
1
0.01 to 100 step 0.01s
This time multiplier setting is used to adjust the operating time of the IEEE/US IDMT curves.
6.
IN2>3 Reset Char
DT
DT/IDMT
This setting determines the type of reset/release characteristics. IDMT applicable for IEEE curves only.
7.
IN2>3 RTMS
1
0.025 to 1.2 step 0.005
This setting determines the reset/release time for IEEE IDMT characteristic
8.
IN2>3 tRESET
0.01 S
0 to 100s step 0.01s
This setting determines the reset/release time for Definite Time (DT) and all IDMT curve
9.
IN2>3 2H Blocking
Disabled
Enabled/Disabled
This setting determines the enabling/disabling of blocking third stage derived earth fault element due to presence of inrush current.
If IN2>3 Blocking and 2nd Harmonic both settings are enabled, then (IN2>3) 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.)

5.
Alarm Threshold
70%
25 to 100% in step 1%
This setting determines the thermal state threshold corresponding to a percentage of the trip threshold at which an alarm will be
generated.
6.
Thermal ConstT1

7.
Thermal ConstΤ2
20 Mins
1 to 360 min step 1
This setting determines the value of starting time constant.
8.
Cooling ConstTr
60 Mins
1 to 999 min step 1
This setting determines the value of cooling time constant.
9.
Thermal Lockout
Enabled
Disabled/Enabled
This setting enables or disables the thermal lockout function which inhibits restart if the thermal state exceeds Lockout threshold.
10.
