Basics of device operation
Standard energizer function
By default, the electric fence energizer operates as a conventional device – when properly powered, it generates a high-voltage impulse approximately every second.
The supply voltage can be provided by a 230 V AC to 12 V DC, 1 A adapter, or by a 12 V lead-acid car battery (at least 70 Ah). Warning: Never connect the device directly to the 230 V AC mains! For 12 V lead-acid batteries, charging may be accomplished using a solar panel connected through a charge controller. The recommended minimum panel capacity is 100 W.
The device must be installed in a covered location to protect it from rain and snow.
Attention: The device must be mounted in an enclosure that allows reception of both GPS and GSM signals. Therefore, metal enclosures or installation behind thick walls are not suitable!
This section does not cover detailed electric fence design or operational principles. It focuses exclusively on the technical bridge between the electric fence energizer and its data transmission to the www.dl-smart.eu servers.
To properly build and operate an electric fence, users should have sufficient knowledge of fence posts, electric fence wires, maximum allowable fence lengths, electric fence gates, grounding methods, and correct supply voltage selection, including the use of AC/DC adaptors, lead-acid batteries, and solar panels.
Server connection
The device continuously maintains a connection to the dl-smart.eu server using its built-in GSM module over the mobile internet network. It automatically selects the mobile operator with the best signal, but works with any available operator in the area.
Even if the external power supply is interrupted, the device remains operational thanks to its internal rechargeable battery. When fully charged, this backup battery keeps the electronics running for approximately 24 hours, ensuring server communication and GPS tracking. Attention: The internal battery powers only the internal GSM and GPS modules. During a main power outage, the high-voltage impulse generator will not operate!
The device transmits operational measurement data every 2 minutes:
- Fence voltage.
- Supply voltage.
- GSM signal strength.
- GPS coordinates.
Light signals
The status indicator LED (located on the right) is a dual-color LED and uses blue flashes to display the device’s current status. Since this LED indicates important operational information, it is recommended to install the device so the blue flashes are visible from a distance (e.g., using binoculars).
The status signal sequence follows a 5-second cycle, consisting of three segments:
A short or long flash
A group of 3 flashes
A group of 2 flashes
The meaning of each signal segment:
Short / Long Flash, at the start of each 5-second cycle
- Short flash: The device is functioning normally – It has proper GSM and GPS signal and fence voltage is present.
The device is functioning normally
- Long flash: The fence voltage is not present – the impulse generator is turned off or there is a short circuit on the fence line.
No fence voltage
Three flashes
Three flashes indicates no GSM signal. The device cannot connect to the server (no internet connection). In this case, make sure there is a GSM signal in the area (can be checked using a smartphone). If the problem persists, please contact us.
Two flashes
Two flashes indicates no GPS signal. The device cannot determine its current location. After the device is started, it usually takes several minutes to establish a GPS connection. If the problem persists, make sure there is adequate GPS signal at the device’s location (this can be checked using a smartphone).
Continuous flashing
If the device’s internal components fail to communicate correctly, the LED will flash continuously. Note that continuous flashing also occurs briefly during initial startup, while the device performs its initialization sequence. If the problem persists, please contact us.
