6.6
Main parameter settings of the intelligent controller
6.6.1
Test trip setting (taking 2M type as an example)
Example: Test trip setting with short time delay
Note:
1. Reset the "Reset" button after the
test, otherwise the circuit breaker cannot be
closed
2. Press the "Clear Light" key to exit the
setting menu
Press the "Set" key to enter the setting
menu, and then continue to press the key
until the I
r2
indicator light and "kA" light are
on, and the digital display screen displays
"6,400 (default value)"
After closing the circuit
breaker, press the "Trip" key,
then the switch trips after 0.4s
delay, and the reset button
pops up at the same time
6.6.2
Long time delay setting current settings (taking 2M type as an example)
Example: Set the rated current of the circuit breaker from 1,600 A to 800 A
Press the "Set" key to enter the
setting menu, and then
continue to press the key until
the I
r1
indicator light and "A"
light are on, and the digital
display screen displays "1,600"
Press the "-
” key to turn
down the current value
Adjust the current to
“800”
Then press the "Save" key to
save the settings
Note:
Press the "Clear Light" key to exit the setting menu after setting
6.6.3
Reclosing settings (additional for 3H type)
1) Start reclosing setting
Note: When the measured line
voltage is lower than the starting
value of 280 V, i.e. the action
voltage, the intelligent controller will
send the opening signal with a delay
of 0.0 s to make the shunt strip act;
when the voltage is restored to the
return value of 360 V and kept for
10.0 s, the intelligent controller
sends a pulse signal to the closing
electromagnet to make it act, thus
completing the automatic reclosing.
