Datamars Unigizer 15000i Mode D'emploi page 9

20 seconds after the fence becomes heavily loaded, the
energizer may increase its output power to more effectively
energise the fence.
When a warning alarm is issued, switch the energizer off,
locate and remedy fault then turn the energizer on again.
Earth monitoring
The quality of the earth affects the fence voltage. The earth
monitoring feature allows you to keep an eye on the earth
quality to make the most of your electric fence. A low voltage
on the earth monitor indicates a good earth connection. A
high voltage on the earth monitor indicates a poor earth
connection.
Setting up for earth monitoring
The earth monitoring feature works by comparing the voltage
of the energizer's earth system with that of a separate earth
rod. Ensure the separate earth rod is at least 10 m (33')
away from any other earth system including the energizer's
main earth system. Locate the earth rod in the opposite
direction to the lead out wire. Drive one 2 m (6'6") earth rod
into the ground. Use high-voltage, insulated cable and an
earth clamp to connect the earth rod and the energizer's
Fence earth monitor terminal. Make sure the insulation is
stripped back to ensure good contact between the wire and
the earth rod.
Monitoring the earth
If the first Indicator light is illuminated permanently, this
indicates that the earth voltage is over 0.8 kV and that better
earthing may be beneficial. Either add more earth rods or
find a better location for the energizer earth system. The
small digits on the LCD display show the voltage going to the
earth system when the selector switch is set to
or . The earth voltage should remain below 0.8 kV at all
times. If the earth monitor voltage numbers flash 3.0 kV, this
indicates the earth voltage is above 3.0 kV. See
