Place a short (using an alligator to alligator “jumper” cable) on the fence at
approximately the midpoint (end of sector 10 for a 20-sector fence) from
live to a ground wire. This represents the hardest fault to detect, as other
positions will draw more current.
Turn the fence (energizer) on.
Check that the energizer goes into alarm. If it does not, reduce the Current
Alarm Level
and then click
Save Settings.
Tips:
a. To ensure the energizer goes into “current” alarm change Fence
Voltage Alarm level to 0 and turn Anti-bridging off, then click Save
Settings.
b. Since the sector programming means placing intentional shorts on
the fence, to stop alarms sounding: Remove any connection to a si -
ren and change the Siren on Time to 0. Finally set the Pulse Time (or
cycle time) to the maximum value to provide enough time to read
the Fence Current once the system is settled. Click Save Settings.
c. On the main page observe the minimum Feed Current. Go back to
the
Configuration
page and change the
Current Alarm 1
to a value
less than the minimum Feed Current that you saw on the main page.
Click Save Settings.
