7 Protection Parameter Settings
2. tclp Time Delay 7200 S 0 to 14400s step 1s
This setting controls the period of time for which the relevant overcurrent and earth fault settings are altered or inhibited following circuit
breaker closure.
3. I>1 Status Enabled Blocked / Enabled
The I>1 status cells have two setting options, "Enabled" and "Blocked". Selecting "Enabled" for a particular stage means that the current
and time settings programmed in the following cells will be adopted during the "tclp" time. Selecting "Blocked" simply blocks the relevant
protection stage during the "tclp" time. It also removes the following current and time settings for that stage from the menu.
4. I>1 Current Set 1.50*In 0.05 to 4.00*In step 0.01*In
This setting determines the new pick-up setting for first stage overcurrent element during the tclp time delay.
5. I>1 Time Delay 0.01 S 0s to 100s step 0.01s
This setting determines the new operating time delay for the first stage definite time overcurrent element during the tclp time.
0.025 to 1.2 in step 0.005
This setting determines the new time multiplier setting for the first stage element to adjust the operating time of the IEC / UK IDMT
characteristic during the tclp time.
This setting determines the
new time dial setting for the first stage overcurrent element to adjust the operating time of the IEEE / US IDMT
characteristic during the tclp time.
The I>2 status cells have two setting options, "Enabled" and "Blocked". Selecting "Enabled" for a particular stage means that the current
and time settings programmed in the following cells will be adopted during the "tclp" time. Selecting "Blocked" simply blocks the relevant
protection stage during the "tclp" time. It also removes the following current and time settings for that stage from the menu.
9. I>2 Current Set 1.50*In 0.05 to 4.00*In step 0.01*In
This setting determines the new pick-up setting for second stage overcurrent element during the tclp time delay.
This setting determines the new operating time delay for the second stage definite time overcurrent element during the tclp time.
11. I>2 TMS 0.100 0.025 to 1.2 step 0.005
This setting determines the new time multiplier setting for the second stage element to adjust the operating time of the IEC / UK IDMT
characteristic during the tclp time.
12. I>2 Time Dial 1 0.01 to 100 step 0.01
This setting determines the new time dial setting for the second stage overcurrent element to adjust the operating time of the IEEE / US
IDMT characteristic during the tclp time
13. I>3 Status Enabled Blocked / Enabled
The I>3 status cells have two setting options, "Enabled" and "Blocked". Selecting "Enabled" for a particular stage means that the current
and time settings programmed in the following cells will be adopted during the "tclp" time. Selecting "Block" simply blocks the relevant
protection stage during the "tclp" time. It also removes the following current and time settings for that stage from the menu
14. I>3 Current Set 1.50*In 0.05 to 4.00*In step 0.01*In
This setting determines the new pick-up setting for third stage overcurrent element during the tclp time delay.
15. I>3 Time Delay 0.01 S 0s to 100s step 0.01s
This setting determines the new operating time delay for the third stage definite time overcurrent element during the tclp time.
This setting determines the new time multiplier setting for the third stage element to adjust the operating time of the IEC / UK IDMT
characteristic during the tclp time.
This setting determines the new time dial setting for the third stage overcurrent element to adjust the operating time of the IEEE / US
IDMT characteristic during the tclp time
The IN1>1 status cells have two setting options, "Enabled" and "Blocked". Selecting "Enabled" for a particular stage means that the
current and time settings programmed in the following cells will be adopted during the "tclp" time. Selecting "Blocked" simply blocks the
relevant protection stage during the "tclp" time. It also removes the following current and time settings for that stage from the menu.
