SECTOR PROGRAMMING METHOD -
LOOP MONITOR (JMBX-ZM50 ONLY)
In order to determine which Sector the fault is in, the system must be pro

grammed with the end position of each sector (the division between each
sector, also known as the sector “split”).
NOTE: Make sure the energizer cover is on if there is any chance of sunlight
hitting the PCB. Bright light shining on the IR optical couplers will cause er

rors in the readings.
12.1 USING THE VIRTUAL KEYPAD
1. Clear the settings
When first setting up a new fence leave sectoring off until you are sure the
fence is working correctly and there are no faults. If the sectoring system
was previously on, turn it off now to clear the settings by changing the

value to 0 and click
Save Settings.
2. Check the Fence
Check the fence by running over it, using a JVA Fault finder (Pakton Power
Probe). The current from each feed terminal (feed 1 and 2 measured at the
fence) should be the same, or very similar. If one is much higher than the
other, you may have a fault in which case do not proceed until you find and
eliminate all faults.
3. Check the Energizer goes into current alarm
Place a link from Feed 1 to Feed 2 at the JMBx-ZM50 terminals, leaving the
wiring to the fence in place.
