reverses. The KY element refers to a two-wire variant of KYZ, where only the K and Y
wires are used in a “normally open” configuration.
The intent of both KY and KYZ elements are mainly for meter verification and the
output of energy pulses are sent to an external counter.
KYZ configuration in the PPX II is achieved by navigating to the Settings / Input screen
of the instruments webserver.
When the 4 digital in/4 digital out option is ordered, the positive and negative KWHr
and KVarHr can be assigned to any of the four outputs in whatever order is desired.
The energy pulse LED is tied only to KWHr. Each of the outputs can be disabled if
there is no desire to tie the energy to the digital outputs, while still enabling the LED.
When the output option is not ordered, the four outputs will show as Disabled and
can’t be changed.
Explanation of KYZ Parameters
Energy per Pulse (EPP)

The EPP parameter has a range of 10 -5 to 10 4 with units of KWhr / kVARhr.

The default value of EPP is 10 KWhr / kVARhr primary engineering units.
