Energy Pulsing Setup

Each meter has both the Calibration Pulser module and the Pulser module.

Pulser Module Settings

The Pulser module serves as an intermediary between other modules’ pulse output registers (accepting them as pulse inputs) and a hardware output channel on the device. These modules are capable of sending pulses or pulse transitions to any hardware output channel. The Pulser module contains the following setup registers:

Setup	Function	Default
Register
Pulse Width	This numeric bounded register specifies the width, in seconds,	1
	of the output pulses.
OutputMode	This register defines whether the output is a complete pulse or	Pulse
	a transition pulse (KYZ).
Polarity	This register specifies the polarity of output. It has no effect if	Non-inverting
	OutputMode is KYZ.
	This register specifies which hardware port the output appears
Port	on. Only those hardware channels that are still available	Not Used
	appear when you access this setting.

Five common parameters (kWh del, kWh rec, kVARh del, kVARh rec, and kW sd del) are already linked to the Pulser modules for you.

NOTE

For safety reasons, no hardware channel has been selected. To make use of these links, you must configure the Pulser modules’ Port setup registers to the appropriate hardware port that receives the output.

Calibration Pulser Module Settings

The Calibration Pulser module is a highly accurate energy pulser used for verifying calibration on meters employed in billing applications. This module type serves as an intermediary between the power (kW, kVAR or kVA) outputs of the Power Meter module and a device’s hardware output channel.

The setup registers of the module labeled “kWh Pulser –D4,” allow you to configure the solid-state output D4 for calibration pulsing. By default, the output on a standard meter generates a pulse for every 1.8Wh accumulated. This is the same pulsing rate as the middle front panel LED (controlled by a Calibration Pulser module labeled “kWh Pulser –LED”). You can modify the pulsing rate of either channel by changing the value of the Kt setup register of the controlling Calibration Pulser module (see below).
