FIGURE 3–9: 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.

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.
