optical fiber communicable for underground cable display the fault signals using LED flashing lights
TYHD-1 panel type fault indicator(be called indicator for short below) is mainly used for indicate short circuit fault and earth fault on the On/Off panel, and used for output wireless signal.
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.
The appearance of the indicator :
Specification of installing:
L1 is connect with A live line
L2 is connect with B live line
L3 is connect with C live line
L4 is connect with Earth line
V1.08 is the version number of software
Fault indicate function:
The lights on the L1,L2,L3,and Earth buttons will flash with a 5-minutes interval,if the short circuit fault or earth fault occur.This can be returned to the original condition automatically according to the time delay set by the factory or by pressing button of “Reset/Test” manually.the low battery capacity of the indicator is show on the panel by wireless,The indicator of low battery voltage will flash at the same time(with 4 seconds interval).
Reset/Test function:
Restore:press the “Reset/Test” button slightly,then restore after all lights have light.
Self-checking:

Function:
1)Show short circuit fault and earth fault locally.
2)Self-reset ,the interval time of self-reset can be set before delivery from factory (The default is 12 hours).
3)Reset or self-test manually.
4)Set the addresses of the indicators
