Adding the "Modbus retrofit" board to your energizer and instructional video series

STEP 1

Attach the retrofit board to your energizer. You'll need:

Screw and spacer kit.

Philips screwdriver

The modbus retrofit board is designed to attach to your existing field installed electrical energizer, hence "retrofit". the black transformer attached to your energizer has 4 holes, one in each corner. 

The modbus retrofit board is designed to attach to your existing field installed electrical energizer, hence "retrofit". the black transformer attached to your energizer has 4 holes, one in each corner. The screw and spacer kit above contains masonry screws which will self tap into the holes on your transformer. This will allow you to install the board on top of your energizer without having to remove your energizer from it's enclosure. 

Please ensure that your Energizer is disconnected from power before attempting this procedure. 

Ferrules, flat headed electrical stripper and a ferrule crimping tool.

STEP 2

There are 3 electrical connections which require to be made in order for the Retrofit board to work.

1) The "Synch" connection.

Historically, all APS energizers have come with a "synch" board which allows multiple boards to be synchronized. The retrofit board obsoletes this board. Your Retrofit board will have a 2 pin connector already attached to it which is to be installed in the "control" terminal of the Energizer.

This means that the 8 pin connector powering your energizer will need to be replaced with a 6 pin version, provided with the install kit, in conjucntion with the 2 pin connector pigtail connected to your board .

2) High voltage return

In order for the Retrofit board to be able to monitor the return voltage from your fence, a clip (similar to one typically used in a test lead) is provided already attached to the board designed to "hook onto" the legs of a resistor which is in line with the return voltage signal. the hook on point can be seen below and is located underneath the "slot" visible in your retrofit board. 

 

3) Power. 

Ensuring that the power is switched off, unscrew the power connection on your 8 pin energizer plug. Twist together with the exposed wire pigtail on the "power" connector of your retrofit board. Use the red ferrules provided with your install kit to crush together the input power to your energizer and the retrofit board. Use your flat headed screwdriver to attach your power pins to the 6 pin header connector.

Now re-attach the 6 pin power connector the the energizer board. 

Where to clip the "HV return" lead.

STEP 3

Windows computer, Modbus windows APP and USB C cable.

Now that the hardware side is setup, we can configure the settings on the modbus retrofit board. In this example, I've unclipped the "synch" connection just so we can configure the board without the Energizer being "live".

Connect your USB C cable between the Retrofit board and your Windows PC. Power up the Retrofit board. WIth regards power, the board will run comfortably between 12-24 volts. At 12 volts the current draw is typically between 50-60mA. 

In order to confirm that the board is powered, you will see the LED circled to the left (green ) flashing twice a second. Once plugged into your Windows computer, it will be detected as a USB device.

DRIVERS. The Modbus retrofit board contains an STM microcontroller and requires the correct drivers to be installed on your Windows PC. If the PC does not detect and install the correct drivers, you can download them from here. 

STEP 4

> Go to "Device Manager" on your WIndows PC. 

> Open up the "ports"  setting and identify the  com port associated with your modbus retrofit board and take a note of it.

> Open up the "Modbus.exe" program.

> Select "USB" and select the com port number from the drop-down list provided. 

> Hit "connect".
