4. Check the Current Balance
With the link and fence short still in place (from step 3):
Check that the position reading is at 50% of full fence length.
Note that you can view the balance by going to the Sectorize page at any
time.
If the reading is not very close to 50%, you will need to re balance the cur -
rent sensors by selecting the “balance” option.
Note: The energizer will not re-balance if either current is less than 5A or
greater than 75A.
If you cannot achieve balance do not proceed. Contact your JVA dealer for
help.
Assuming the fence is balanced, disarm the energizer (turn the fence off).
Remove the link from Feed 1 to Feed 2 at the energizer terminals.
Remove the short that was placed on the fence from step 3.
5. Engage Sectoring
Go to the Configuration page and set the Sector to 20 (for 20 sectors, or
however many sectors the fence has). Click Save Settings.
6. Record sector end points
Place a short (using an alligator to alligator “jumper” cable) at the very end
of sector 1 between live and earth preferably using the fence earth wire
nearest the exit point of sector 1. Sector 1 is the sector directly powered
from the Feed 1 terminal.
If you are using a Sector Divider (PTE0063) place the short from the centre
terminal to ground.
When the energizer goes into alarm it will display Sector 1 - Short and the
position (as a percentage of the whole fence length.
