MPG-2ES
Standard Solid State
WIRE HARNESS
CONNECTIONS
GENERAL - The MPG-2ES is a scaled-down, specific purpose version of the MPG-1C and MPG-2 that allows cost
reduction when only basic features and one K-Y output are needed.
MOUNTING POSITION - The MPG-2ES may be mounted in any position but is intended to be mounted with the
orientation above such that the circuit board is upright. The MPG-2ES must be mounted within 75' of the meter.
Actual operational distance may vary with building construction and ability for the RF signal to penetrate building
materials. For best results, mount the MPG-2ES as close to the meter as reasonably possible.
POWER SUPPLY INPUT - The MPG-2ES is powered from +5VDC. Connect the RED wire to the +5VDC positive
source. Connect the BLK wire to the 5VDC ground (negative) terminal.
ZIGBEE WIRELESS COMMUNICATION - The MPG-2ES is designed to receive power monitoring information from
an electric meter equipped with Zigbee wireless communications. The Zigbee tranceiver dongle is mounted on the
MPG-2ES's circuit board. Ensure that the dongle is properly seated in the USB host socket. Do not remove.
PULSE OUTPUT - A 2-wire (Form A) K-Y output is available for connection to the pulse receiving device. The BLK
wire is connected to the K terminal. The YEL wire is connected to the Y terminal. The output load should be limited
to 100 mA at 24 VAC/VDC with maximum output power dissipation of 800mW.
OPERATION - See the following pages for a full explanation of the operation of the MPG-2ES.

- Page 3 Hardware Installation - Once you are confident that the MPG-2ES's Zigbee transceiver is paired with the meter, completing the installation of the physical unit is the next step. If the utility is doing the MPG-2ES installation and they are experienced in provisioning, then the provisioning process may be done after installation. Installation includes mounting the unit at or near the electric meter and connecting the outputs to the destination (pulse receiving) devices.
- Page 4 Power up the MPG-2ES for Provisioning Apply power to the MPG-2ES using the +5VDC source. Make sure to get the positive lead (usually red) is connected to the +5V terminal. Connect the negative lead (usually black) connected to the GND terminal. Upon power-up the yellow COM LED will light indicating the the MPG-2ES's microprocessor senses the presence of the Zigbee dongle and that it is installed correctly.
- Page 5 RED LED on the dongle should be lit continuously. The SSI Universal Programmer software should immediately recognize that it is connected to the MPG-2ES. A green simulated LED at the top of the programming page indicates that the connection has been made.
- Page 6 KYZ 3-Wire electric meter output. It toggles back and forth, to the opposite state, each time a "pulse" is generated by the MPG-2ES. Even though there are three wires, it is common to use K and Y, or K and Z, for many two-wire systems that require or desire a generally symmetrical 50/50 duty cycle pulse.

- Page 8 Depending on the device receiving the pulses and the methodology it uses to interpret them, this can be a great help in representing the real kW demand and eliminate the quantitization problem caused by the meter's measureement method. To enable the filter mode select Enable in the Filter field. Hit <Send>. The serial link on the MPG-2ES will return the following:...

Remember to change the pulse constant of your receiving device as well, since pulses will now be worth a higher watt-hour value. Cycle power to the MPG-2ES to reset the red COM LED... - Page 10 3-Wire pulse metering and emulates the SPST KYZ switch model. Figure 1 below shows the timing diagram for the Toggle output mode. Since the MPG-2ES uses only 2 wires, there are only KY closures. KY closures are alternately opened and closed. This mode is best for timing pulses to derive kW demand.
- Page 11 No pulses are outputted when there is negative energy flow. Therefore, Normal and Signed mode in the MPG-2ES are essentially the same. The only option would be whether positive pulses are toggle or fixed as shown below.
- Page 12 Here is a list of the available commands if you are using an ASCII terminal program instead of the SSI Universal Programmer software. If you don't remember them use the help, 'h', 'H', or '?' to bring up the list.
