Display and working status

The display state can be divided into: reset state (power-on default state), parameter setting state, fault display state, fault query state and alarm state.

Different states are distinguished by the combination of the LCD window to distinguish the specific state as follows:

a, reset state (power-on default state): At this time, the controller does not have any operation, and is in a trouble-free operation state. Default state, the LCD screen display content for the "Run" is always lit + "1" is always lit, 3P "A" "B ""C"" is always lighted in turn, 4P "A""B""C ""N" rotating display, the numerical window displays the current, the current unit "A" is always lit.

b. Parameter setting state: This state of the controller can modify and query the setting value of the protection. Default state, press the "OK" key, the LCD screen display content for the "Run" is always lit + "Set" is always lit + "1" is always lit, 3P When "A", "B" and "C" are displayed in turn, 4P "A", "B" and "C" are displayed in turn, 4P "A", "B" and "C" are displayed in turn, 4P "A", "B" and "C" are displayed in turn. "B" "C" "N' rotating display, the numerical window displays the current, the current unit "A" is always lit. And then press "OK" key, the LCD display content for "Set" is always on + "I" is always on, the numerical value window display, the relevant unit is always on. At this time, press the "up" or "down" in the Ir", "tr, "sd", "lsd", "Li", "Li", "Li", "Li", "Li", "Li", "Li", "Li", "Li", "Li", "Li", "Li", "Li", "Li", "Li", "Li" and "Li". Li", "lp", "Ig", "tg" 1△n" "t△ ""unbal"" tunbal cycle selection. When "Set" is always on + "Ir" is always on, press "ok" again to enter the overload long delay current setting, at this time, "Set" flashes + "Ir" is always on. At this time, "Set" is flashing + "Ir" is always on, press "up" or "down" to adjust, and then press "ok" to save. At this time, press "up" or "down" in "lr" "tr" "lsd ""tsd""li""lp""lg "tg ""1△n""t△""lunba""tunbal'" cycle selection. At this time, press ESC twice to the default state. If any key is not pressed, the default state will be returned after 30s.

C. Fault display state: This state of the controller indicates that the controller is in the state of fault release. Fault interface, with auxiliary power supply, the display content is "Fault" is always lit + "Run" is always lit + "I" is always lit, fault current phase is "A", "B", "C", "N" in one always lit. One of "A", "B", "C" and "N" is always on, and the numerical window displays the current, and the current unit "A" is always on or "B" is always on or "C" is always on. "A" is always on or "kA" is always on.

At this time, press the "up" key or "down" key to switch to view the fault action time or current, view the fault action time, the numerical window displays the time, the time unit "s" or "ms". The time unit "s" or "ms" is displayed. If there is no auxiliary power supply, the switch will be off and not displayed.

d. Fault query state: The controller can query the parameters of the last fault record in this state. Fault query interface, the default state, press the "OK" key, the LCD display content for the "Run" is always lit + "Set" is always lit + "I" is always lit, 3P "A ""B""C" is always on in turn, and "A""B""C""N" is always on in turn for 4P. "N" is displayed in turn, the numerical window displays the current, and the current unit "A" is always on. And then press the "up" key or "down" key, at this time, "Fault" is always on + "Run" is always on + "Set" is always on + "B", "C", "N" is always on, the current unit "A" is always on. "Set" is always on + "I" is always on, 3P "A" "B" "C" is displayed in turn, "A", "B", "C", "N" is displayed in turn when 4P, the numerical value window displays the current, and the current unit "A The current is displayed in the numerical window, and the current unit "A" is always on. Press 0K" key again, "Fault" is always on + "I" is always on and fault lamp type indication "Ir", "Isd", Ii", "Ig", "lunbal" lamp is always on, if "Ir", "Isd", "li", "Ii", "Ig", "lunbal" lamp is always on. If "Ir", "Isd", "li", "Ig" current fault, at this time the fault current phase "A", "B", "C" "N" in a constant light, the numerical window shows the current, the current unit "A" is always bright or "kA" is always bright. At this time, press the "up" key or "down" key to switch to view the fault action time or current, view the fault action time, the numerical window displays the time, the time unit "s" or "ms". The time unit "s" or "ms" is displayed.

e, alarm status: controller this state that the controller has detected a measured parameter exceeds the set value of the situation, generally when the current is greater than the set value of the overload warning current is displayed. Alarm interface, LCD screen display content for the "Alarm" is always on + "Run" is always on + "I" is always on, fault current phase "A"" B", "C", "N' in a constant light, the numerical window displays the current, the current unit "A" constant light or "kA" constant light.
