Description
1
Measurement
display
ZCT primary earth leakage current RMS of each power system line is displayed on 7-
segment.
2
Circuit display
Applied power system line is displayed on 7-segment when ZCT connection test and
earth leakage detector operate test.
Applied power system line is displayed when Earth leakage fault occurred.
3
Circuit selection
Switch
Applied power system line selection when ZCT connection test and operation test.
The circuit switch for checking the earth leakage detector operated power system line after
occuring of earth leakage fault.
4
Connection status
LED
When press the test switch, turn on the LED(yellow), if connection of ZCT with earth
leakage detector was correct.
5
Test Switch
The test switch that is tested the ZCT connection status and earth leakage detector
operation of each circuit.
6
Power LED
Turn on the power LED(green) when earth leakage detector power supply voltage is
supplied.
7
Alarm LED
Turn on the alarm LED(red) when earth leakage detector operated.
8
Reset Switch
The Auto/Manual switch set to manual, and even if the earth leakage of power system
line became to recover when the earth leakage detector operated, the operation status is
continuous. if you want to restore, use this switch.
9
Auto LED
Turn on the Auto LED(green) when Auto/Manual switch be Auto.
10
Manual LED
Turn on the Manual LED(yellow) when Auto/Manual switch be Manual.
11
Auto/Manual
Switch
Auto
If earth leakage power system line is recover, earth leakage detector
operation status is recover automatically.
Manual
Operation status is continuous even if earth leakage power system line
became recovered. If want to recover, must press the reset switch.
12
Buzzer ON LED
Turn on the ON LED(green) when Buzzer ON/OFF switch be ON.
13
Buzzer OFF LED
Turn on the OFF LED(yellow) when Buzzer ON/OFF switch be OFF.
14
Buzzer ON/OFF
Switch
Buzzer
ON
Alarm sound is operate when the earth leakage fault occurred on state of
Buzzer ON.
