Explanation of some terms used in this section
• Low Fence Voltage Alarm set point is the fence voltage above which the Electric
Fence onitor will show a working fence and below which the Electric Fence onitor
will show a failing fence.
The PTE0700 series Electric Fence onitors allow you to manually adjust this set
point, or alternatively they can be set to automatically adjust this set point.
When automatically adjusting, it also ‘follows’ the fence’s performance. If, for example,
the fence were operating at 7kV when the Electric Fence onitor is switched on, it
would set its Low Fence Voltage Alarm set point at about 6kV. As days go by, grass
might build up on the electric fence, lowering the voltage on the fence, or a dry spell
might slowly increase the voltage on the fence. The Electric Fence onitor sees the
gradual change and adjusts its set point accordingly. If, however, the fence voltage
drops more quickly the Electric Fence onitor will raise an alarm. False alarms are
less likely to be raised if the Electric Fence onitor is allowed to automatically adjust
its set point. Another advantage of using auto-adjustment is that the onitor will also
alarm on a quickly rising voltage.
• Adjustable elay from Low Fence Voltage to firing alarm is the adjustable
amount of time the Electric Fence onitor waits after the fence fails before it raises an
alarm. For example, If the delay is set to six seconds, and the fence voltage goes low
for only three seconds, no alarm is raised. The alarm would only be raised if the fence
voltage stayed below the Low Fence Voltage Alarm set point for more than six
seconds.
• Alarms failing fence with internal beeper means that a small siren contained within
the Electric Fence onitor will sound when the fence voltage goes below the Low
Fence Voltage Alarm Set Point.
• Alarms failing fence by setting relay there is one relay inside the Electric Fence
onitor, with three terminals, discussed fully in Section 0 “Relay Output” below.
• 12v C powered means that the Electric Fence onitor is powered by any nominal
twelve-volt supply such as a mains plug pack or battery.
• 10kV opto isolation from fence inputs means that the fence inputs are not
electrically connected to the rest of the circuitry. Instead, they are connected optically.
This means that all accessories connected to the Electric Fence onitor and the
Electric Fence onitor itself are protected from excessive voltages on the fence.
• Current output 4-20mA proportional to 0-10kV input means that the Electric
Fence onitor can supply an industry standard analogue signal to other equipment
such as SCADA or Telemetry RTU.
