TYHD-2 panel type fault indicator(be called indicator for short below) is mainly used for switch gears for locally indicate short circuit fault and earth fault and also provide wireless signal output .
Working principle:
The principle is micro-controllers with little power consumption, micro-controllers can automatically identify fault signals from short circuit indicator and earth indicator, They can display the fault signals using LED flashing lights on the spot and output the signals by wireless.
Installing methods:
The appearance of the indicator :
Method of installing:
L1 connects with A phase for signal input from optical fiber
L2 connects with B phase for signal input from optical fiber
L3 connects with C phase for signal input from optical fiber
L4 connects with Earth line for signal input from optical fiber
Fault indicate function:
The lights on the L1,L2,L3,and Earth buttons will flash with a an interval of 4 seconds,if the short circuit fault or earth fault occur.This can be reset automatically according to the time delay set before delivery from the factory or manually reset by pressing button of “Reset/Test”.the status of low battery capacity of the indicator can be uploaded by wireless,in the meantime, The indicator will flash for low battery voltage(with 4 seconds of interval).
Reset/Test function:
1) Reset: press lightly the “Reset/Test” button slightly, it will reset after all lights on in indicator
2)Self-checking
3)L1,L2,Wireless function self-checking
4)indicator address configure
Performance index:
1.The distance of fiber communication:Typical value:5m
2.Battery can be changed
Test function:
Self-checking:
Press ““Reset/Test” button, press on L1 and L2 in turn, then let go, after all lights are on at mean time once, the corresponding address lights is on. In 10s, corresponding address lights are on again, then self-checking finished.
instructions is as following table:
| Address | black point means the corresponding LED is on | |||
