Mains Signaling Evaluation Module Settings
To enable EN50160 mains signal voltage monitoring, you must specify the signal
frequency of interest and the allowable signal voltage threshold for each of the
three voltage phases. These parameters are held in the Frequency and Limit setup
registers of their respective Mains Signaling Evaluation modules.
The allowable Frequency range is 5 Hz to 2500 Hz (default is 1060 Hz). If this
register is set to 0Hz, then no evaluation will be performed. The voltage threshold
defined by the Limit setup register must be expressed as a percentage of the
fundamental (default is 100%). Refer to the online ION Programmer’s Reference for
more details about this module.
