I/O SETUP
The I/O Setup section is divided into two categories; Pulse Initiation and Internal I/O.
PULSE INITIATION SETUP
The default mode for all outputs is Host Control. To select an output for Pulse Initiation, select this
feature in the I/O Setup page, assigning a source and pulse constant . Pulse constants are handled
differently for S1 and S2 verses R1, R2, and R3. S1 and S2 pulse constants are entered in second-
ary rated Watt-Seconds per pulse (not including CT and PT ratios). R1, R2, and R3 pulse constants
are entered in primary rated Watt-Hours per pulse. (CT and PT ratios are automatically factored.)
The meter generates pulses through discrete or relay outputs based on the value of selected ac-
cumulators. This is a fixed pulse and fixed width; 0 to 1000 kWh scaling factor. The meter can serve
as a pulse initiator for all energies: real, reactive, or apparent.
The Pulse Initiation Setup section allows you to select the Source and Pulse Constant for the two
solid-state relay outputs (S1 and S2) and the three outputs (R1, R2, and R3).
You can select Watt hours Forward or Reverse, VAR hours received or delivered, or VA hours and
enter the Pulse Constant for each.
For S1 and S2 (solid state outputs), the entered pulse constant is in Watt-second secondary. For
example, if the CT Ratio is 5000:5, the PT Ratio is 120:120 and the pulse constant is set to 3600
