Configuring energy pulsing

Use Power Monitoring Expert or ION Setup to change your meter’s energy pulsing settings.

warning

HAZARD OF UNEXPECTED DIGITAL OUTPUT PULSE

● Do not use the meter for critical control or protection applications where human or equipment safety relies on the operation of the control circuit.
● Be aware that an unexpected pulse on the digital outputs can result when the supply power to the meter is interrupted or after a meter firmware or template upgrade.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

 

Using the front panel

You cannot configure energy pulsing using the front panel.

Using ION Setup

  1. Open the Setup Assistant for your meter. See the ION Setup Help for instructions.
  2. Select LED Pulsing.
  3. Click on the tab that corresponds to the LED that you want to configure.
  4. Configure the settings as required. See Calibration Pulser module settings for more information on the settings other than Pulser Mode.

    Pulser Mode determines whether the LED pulsing occurs always or only when the meter is in TEST mode.

    The appropriate Kt value depends on Scaled Rev Param (located on the Basic Setup tab).

    – If Scaled Rev Param is OFF, the Kt value must be the primary value and the Calibration Pulser module pulses based on primary kWh and kVARh

    5. – If Scaled Rev Param is ON, the Kt value must be the secondary value, and the Calibration Pulser module pulses based on secondary kWh and kVARh.

  5. Select the Energy Pulsing screen to configure the other default Calibration Pulser modules for energy pulsing applications, if required. By default, these modules are not linked to an output.
  6. Click the End of Interval tab to configure the end of energy pulsing.

Using Designer

Open your meter in Designer and navigate to the Energy Pulsing Setup folder. Right- click a module to edit.

Calibration Pulser module settings

The setup registers available in the Calibration Pulser module are listed in the table below. The defaults listed are for the two pre-configured Calibration Pulser modules that control the front panel LEDs (these modules are labelled Wh Pulse LED and VARh Pulse LED).

Setup register Function Default

Pulse Width

Specifies the width of the pulses sent to the hardware channel (in seconds). The Calibration Pulser module maintains a minimum duty cycle of 50% on the output pulse train.

 

0.05

Kt

The numeric bounded register defines how much energy the module accumulates before a pulse is sent to the hardware channel. An industry standard for energy pulsing is 1.8, or one pulse per 1.8 energy-hours.

varies¹

Int Mode

Specifies the modes of integration that can be selected.

Absolute

OutputMode

Specifies whether the output is a complete pulse (Pulse) or a change of state transition (KYZ).

Pulse

Port

Specifies which hardware port the pulse/KYZ transition appears on. Only those hardware channels that are still available appear in this list.

Not Used

¹ The default Kt value varies depending on the template. For meters with the 9S/29S/36S template, the default is 1.8. For meters with the 35S template, the default is 1.2.

Pulser module settings

Only the End of Interval Pulser module is available by default. The defaults below reflect the defaults in this module.
