PULSE OUTPUT

Figure 3.1: Close-up of the Relay and KYZ pulse output on the rear panel.

Note: The relays shown in the figure above are in the NOT energized state.

THE INSTRUMENT DETECTS TWO LEVELS OF ALARM FOR THE FOLLOWING FUNCTIONS:

Voltage:

AN, BN, CN, AB, BC, CA

Current:

A, B, C, N

Over and Reverse Power

Under PF/KVAR Lead or Lag

Over KVA

Voltage Imbalance (One level only)

Over/Under Frequency

Voltage Phase Reversals (One level only)

Over/Under %THD (Available only with option –H)

Over/Under K-Factor

KYZ RELAYS: Provides pulses for energy management systems or any other type of recording device. These pulses represent accumulated watt-hour, negative watt-hour, or VA-hour. Accomplish this assignment through the Programming Mode (see programming sections). The pulse value is determined by the decimal increment of the power function assigned to the pulse. The EPM 5200P can be equipped with KYZ pulse outputs.

NOTE: Unless otherwise specified, standard KYZ setup represents positive watt hour. See table below for standard rate. 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.

3.8: 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.
