AC Line Frequency
Specify the ac line frequency. Since the controller reduces
the effect of power line noise on the analog measurement by
integrating the signal over the period of the ac line frequen-
cy, the controller must know the frequency of power in use.
You must switch power to the controller off, then back on,
to make a change to this parameter take effect.
Selectable values: 50 or 60 Hz.
Digital Output Polarity on Alarm
Set the polarity of all digital outputs used for alarms. If LOW
is selected, if an alarm occurs the outputs sink to analog
common. If HIGH is selected, the outputs sink to common
when no alarm is active and go high when an alarm occurs.
Selectable values: HIGH or LOW.
This parameter does not affect the Global Alarm output or
the Watchdog Alarm output.
