CHAPTER 3: ELECTRICAL INSTALLATION KYZ PULSE OUTPUTS: NL2 OPTION
EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 3–19
3.9 KYZ Pulse Outputs: NL2 Option
The -NL2 option for the meter is equipped with three KYZ outputs. KYZ relays provide
pulses for energy management systems or any other type of recording device. These
pulses represent accumulated positive watt-hour, negative watt-hour, VA-hour, positive
VAR-hour, or negative VAR-hour. Accomplish this through Programming Mode GROUP 0,
FUNCTION 6. The pulse value is dependent upon the Decimal Point Placement and is
determined by the decimal increment of the power function assigned to the pulse. Refer to
the situation that applies to the meter setting.
Unless otherwise specified, standard KYZ setup for Pulse Output 0 is positive Watt Hour,
Pulse Output 1 is negative Watt-Hour, and Pulse Output 2 is VA-hour. See table below for
With Option R (available only with the EPM 5200P) the setup for Pulse Output 0 is positive
Watt-Hour, Pulse output 1 is positive VAR-hour, and Pulse output 2 is negative VAR-hour.
The scale factor for Wattage (KW or MW) and Full Scale Decimal Point Placement is
selectable in Programming Mode GROUP 1, FUNCTION 2. Follow the Decimal Point
Placement corresponding to the Change in Level. A multiplication or division factor can be
programmed. See Programming GROUP 0, FUNCTION 6 for a different rate.
