Powermonitor 3000 Operations 3-27
Relay and KYZ Pulse Operation Setup
Use these configuration parameters to select how the relay and KYZ
solid-state outputs are controlled.
Relay control source controls the
selection which includes:
•
Disabled
•
Wh forward
•
Wh reverse
•
VARh forward
•
VARh reverse
•
Vah
•
Ah
•
Setpoints (default)
•
Remote I/O or DeviceNet discrete control
The Pulse output scale factor sets the number of measurement
increments per pulse. Range 1 to 30,000, default 10. The Pulse output
width parameter determines the pulse width in milliseconds. Range 40
to 2,000 or 0 to transition the output KYZ-style. Default is 0.
Metering options
Configuration parameters RMS Result Averaging, RMS Resolution and
Frequency Averaging allow you to make choices to fit the
Powermonitor 3000 more closely to your application needs. The
default settings are to average 8 RMS and frequency calculations,
providing a smoother result, and to sample at a high rate, providing
greater accuracy where significant harmonics are present. Refer to the
discussion of these parameters in
Metering Functionality at the
beginning of this chapter.
Configurable Energy Counter Rollover
You may configure the number of digits (range 4 to 15) at which
energy values roll over to zero. Configure this setting using the
Display Module or by writing to Table A.6.
Advanced Metering Options
Some applications require very frequent updates of a limited set of
metering data. In the M8 model, you may de-select certain metering
functions to improve the update rate of the Powermonitor 3000 in its
remaining metering and communications functions. With this feature
selected, de-selected metering calculations return values of 0 in the
appropriate data table elements.
