11.16 DFD™
DFD™ enables the JMB to detect a fault at the end of very long fences.
Instead of only measuring the peak current the JMB with DFD™ calculates
the “real” current and rejects the “reactive” current.
The current displayed will usually be less than read by a standard hand-
held meter with this feature on. There is no theoretical limit to the length
of fence that the JMB can monitor with this feature on. Without DFD™ the
limit is approxi¬mately 10km.
Default OFF.

tance Fault Detect accordingly. Click Save Settings.
11.17 SECTORS
JMBx-ZM50 Only
This option allows your electric fence to be split up into sectors (sections
of fence). When a fault occurs (as defined by the total current exceeding
the “current alarm level”) the energizer will determine which sector the
short is in.
Each sector division needs to be programmed into the energizer. The sec -
tor programming procedure is outlined in Section 12 “Sector Programming
Method” .
The energizer cannot show more than 1 faulted sector at any time
Range 0 to 50. Default 0
