CSSG – STRAIN GAGE INPUT PID MODULE PROGRAMMING
The CSSG module’s parameters are broken into groups, each with their own page. Use the
tabs on the left hand side of the window to view the various pages.
THE GENERAL TAB
INPUTS
The input parameters section contains settings for both inputs. If the module does not have the
optional secondary input fitted, the secondary input parameters are ignored.
• The Range property is used to configure the input for various signal levels. This
allows the module to reconfigure its A/D converter for optimal resolution.
• The Excitation property configures the output excitation voltage for either 5 or
10 Volts.
• The Display Low and Display High properties are used to scale the input to
indicate units of measure. Enter the desired PV readings that correspond to the
Signal Low and Signal High values, respectively. ie. If the application involves a
strain gage that produces a 0 to 21.00 mV output proportional to 0 to 1000 lbs,
enter 0 for the Display Low property, and 1000 for the Display High property.
• The Signal Low and Signal High properties are used to scale the input. Enter the
signal levels that correspond to the Display Low and Display High properties,
respectively. ie. If the application involves a strain gage that produces a 0 to
21.00 mV output proportional to 0 to 1000 lbs, enter 0 for the Signal Low
property, and +21.00 mV for the Signal High property.
OPERATION
• The Control Type property allows you to choose from Reverse only, Direct only
or Reverse and Direct, depending on the type of process to be controlled.
