AC Line Frequency
Use this menu to configure the controller to match an AC line frequency
of 50 or 60 Hz. (This function is provided for international users who
require 50 Hz lines.) 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 frequency, the controller's noise rejection will
suffer if the line frequency is not set correctly.
Selectable values: 50 Hz or 60 Hz.
NOTE
You must switch power to the CLS on and off for a change
in AC line frequency to take effect.
Digital Output Polarity
Use this menu to set the polarity of the digital outputs used for alarms.
Selectable values: High or Low.
EPROM Information
This is a view-only display. It shows the controller's EPROM version
and checksum.
Press any key to return to the Set up Global Parameters menu.
