—EKL--3Panel Mounted Short Circuit and Earth Fault
Indicator
► Models and Specifications
FI-MDJD-01(EKL-3)
► Main Functions
1. Short Circuit Alarm Indication: If a short circuit fault occurs
in the power line and the current reaches or exceeds the threshold
of alarm current. Short-circuit sensor sends out a alarm signal
which will be transmitted to a host through optical fiber. And then
the host generates a corresponding alarm indication signal after receiving this signal.
2. Earth Fault Alarm Indication: If an earth fault occurs in the power line and current reaches or exceeds the
threshold of alarm current. An earth fault sensor sends out a alarm signal which will be transmitted to a host
through optical fiber. And then the host generates a corresponding alarm indication signal after receiving this
signal.
3. Automatic Reset: If indicator sends out a signal and there is no manual reset implemented or delay time
exceeds configured automatic reset time. Indicator will be reset automatically. The automatic reset time is 12 or
24 hours, or other time configured
4. Manual Reset/self-test: If alarm is activated, the indicator can be reset by triggering 'Test / Reset' button on
the control panel of the indicator to stop the alarm.It can also be self tested by pressing the 'Test / Reset' button
for 2 seconds.
5. Automation(optional): Indicator generates a corresponding alarm indication signal which can be output to a
remote-transmission device,including short circuit fault,earth fault and low voltage alarm indication signal,as
well as the alarm signal of remote terminal reset fault.
