Product Description
8020-SCP-424 is a Model 400, 16K Ram Processor with a floating point that is manufactured as part of the PowerLogic series by Square D. The scan speed for this processor is 0.7 milliseconds per K of Boolean logic and 2.9 milliseconds per K of nominal logic. There are a number of error codes on the PC system associated with this processor. Error numbers 00001-00999 indicate a general error. Error numbers 01000-09999 indicate a processor communication port error. Error numbers 10000-18192 indicate a read after write error. Error numbers 19000-19016 indicate a slot error. Error numbers 20000-28192 indicate a slot register error. Error numbers 29000-29999 indicate a miscellaneous error. Error numbers 30000-32700 indicate a CPU/LI Error.
Instantaneous metering functions on the PowerLogic processor include voltage, current, power factor, frequency, real power, reactive power, apparent power, apparent current, and temperature. Demand metering functions include peak and average current, as well as peak, predicted, and average real power. The energy readings include both accumulated energy and accumulated reactive energy. The processor also includes minimum and maximum historical values, monitoring of status inputs, local/remote control of relay outputs, energy management alarms, the PowerLogic application software series, a personal computer interface, a local system display, network communications, modem communications, a waveform capture feature (total harmonic distortion, most significant harmonic component, magnitude of most significant harmonic), custom automatic control functions (data logging, event logging, automatic transfer schemes, load-shedding, sequencing, power factor correction), and connections to other compatible devices (motor protection relays and transformer temperature monitors.
