KYZ PULSE OUTPUTS: NL2 OPTION

3.9KYZ 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 standard rate.

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.
