Zero Capture Diagnostic Operation
Absolute Maximum (Full Scale) Readings
3-24
The value written to parameter index 50 selects the variable that will be written to the
Diagnostic Data word (%AI offset 60) in the PSM Signal Input Data. The Diagnostic Data
word (%AI offset 60) can contain one of the following:

PSM module firmware version

One value of the most recently captured waveform for Grid 1 or Grid 2
Diagnostic Type
Firmware Version
Grid 1 Waveform Capture
address
Grid 2 Waveform Capture
address
The peak values that the PSM system is capable of reading are detailed below. Applying
higher voltages than 1064.9V on the high voltage range, or 212.4V on the low voltage
range (peak value) or higher currents than 10.652A (peak value) to the PSM Interface
Module will lead to the erroneous results. Such a situation will be accompanied by the
appropriate fault bits (FaultXX and ClampedInput) in the %I status bits being set to 1 with
the LED "FLT" flashing or steady red. These are the Full Scale values for their respective
ranges, and are used as the basis for the accuracies in chapter 1, Specifications.
Extended operation at or above the peak values may shorten the mean time between
failure (MTBF) of the PSM system.
