Product Description
How to install SNV-EKL4 v2.1 Earth fault and short circuit indicator
Type: cable type,surface mounted,battery 19000mHA
Description
SNV-EKL4 v2.1, Earth fault and short circuit indicator, it Widely used in various ring cabinets, high/ Medium or low -voltage switch gear and cable branch box in power system, can accurately and reliably detect the fault section and fault type of power grid in the Low/medium voltage network. The use of cable type grounding fault and short circuit indicator is an efficient way to check cable fault, and is an effective way to improve the operation level of distribution network and the efficiency of fault handling. The design uses electromagnetic induction, and single chip microcomputer control technology to make fault alarm with high accuracy and strong anti-interference ability.
Function character:
1) Intelligent detection of ground fault and through the corresponding LED (I0),on the display unit to indicate fault.
2) Intelligent detection of short circuit fault of phase to phase and through the corresponding LED (L1, L2,L3),on the display unit to indicate fault.
3)Display unit designed with button, it is convenient for reset or test.
4)The pulse width time of fault current (Response time) can be set to prevent incorrect fault indication caused by surge current through modbus of RS485 port.
5)It can reset and detect the remote fault indication device remotely by SCADA or press key.
6)It can provide switch volume for external devices through remote contact.
7)It can change the reset time after fault happen through Modbus of RS485 port. (when purchase, it need to tell factory to set,default 8hours).
8)Remote fault indicating can be made by external lamp.
9)Earth fault alarm current (40/50/60/70/80/100/120/250A)
Tripping current(350/400/450/500/550/600/650/700A),8-level can be settable through a DIP switch inside of the display unit.(optional).
10)Low battery display and alarm test through press the “Test/reset” key by 3seconds.
11) Battery can be changeable conveniently, Big capacity 19000mHA,D- Size, ER34615.
12) Sensor cable spec: NYAF,copper cable,(2x1.5㎟ ) ,7 meters length.
13) Support AC/DC power input, AC48-240V.
14) Support Automatic Low voltage reset, AC>30V.

Installation
1) Dimension and installation:
Display unit outside size: 192x90x60mm
Surface mounted on the wall or cabinet bolts M4. Hole distance position: 50mm x 178mm.
Cable gland (M20x1.5): fit for 6-12mm cable.
2) sensor installation
First uninstall one screw off sensor, then install sensor cross through the cable, and screw on again. Then use zip-belt to fixed sensor with cable.
About Earth fault sensor need to round the 3 phases cable conductor together (if have phase N,then directly mounted on phase N cable). And tighten it with belt, and the cable grounding line must insert back the sensor, and tighten it avoid the loose and fall down. As below:
