Packet Power™ Monitoring Module Users Manual

Note: If the current transformer(s) are located in the same enclosure as the PMM,

you must ensure that any electrical code fill rate requirements are being met.

LED readings and indicator lights

The PMM has 3 large alpha-numeric LEDs that provide for local display of monitoring

data and 3 small lights adjacent to the LEDs that provide operating status information.

The PMM can be configured to display all or some of the following data via the numeric

LEDs. The order of display can also be customized. The data type indicator is shown

followed by the corresponding value, e.g. to show a reading of 10.1 amps on channel A,

the PMM displays “A1” followed by “10.1”.

 P5= XXX firmware version

 Id = ABC last 3 digits of the Packet Power node ID

 A1 / A2 / A3 = current on channel A, B or C in Amps

 U1 / U2 / U3 = voltage on channel A, B or C in Volts

 P1 / P2 / P3 = power on channel A, B or C in kilowatts

 F1 / F2 / F3 = power factor on channel A, B or C

 Fr= frequency in Hz

The 3 status lights are interpreted as follows (top, middle and bottom positions assume

that the PMM is viewed such that the status lights are to the right of the large LEDs):

Top small light (green)

 900MHz radio activity

o off: disabled

o solid on: active, not connected

o slow flashing: active, connected to the mesh network

o very rapid flashing: test/configuration mode

Middle small light (red)
