Chxx view parameters (5034-IF4, 5034-IF8C, 5034-IF8V)

The
Chxx
view include these parameters:
Parameter
Description
Disable Channel
Determines whether the channel is disabled. Disable channels to prevent erroneous fault reporting, such as No Load or Open Wire faults, and to prevent the fault indication from the channel status indicator.
Input Type
Sets the input type for the channel. Available options are:
  • Voltage
  • Current
Input Range
Sets the input range for the input type. Ranges vary according to the selected Input Type.
Enable Open Wire Detection
Detects whether the signal wire is disconnected from the channel or the RTB.
  • If selected, the channel detects the open wire condition.
  • If cleared, the channel does not detect the open wire condition.
High Signal
Sets one of the four constants in the scaling equation. High Signal is in terms of the input signal units and corresponds to High Engineering when scaled.
Low Signal
Sets one of the four constants in the scaling equation. Low Signal is in terms of the input signal units and corresponds to Low Engineering when scaled.
Engineering Units
Sets the unit of measurement for High Engineering and Low Engineering.
High Engineering
Sets one of the four constants in the scaling equation. High Engineering corresponds to High Signal and helps determine the engineering units that the signal values scale into.
Low Engineering
Sets one of the four constants in the scaling equation. Low Engineering corresponds to Low Signal and helps determine the engineering units that the signal values scale into.
Recalculate Units
Recalculates new values to the following configuration parameters in Engineering Units based on the new Scaling constants.
  • High High Limit
  • High Limit
  • Low Limit
  • Low Low Limit
  • Rate Alarm Limit
  • Deadband
TIP: This option is enabled when any of the four Scaling constants is changed.
Notch Filter
Sets the notch filter value, which attenuates the input signal at the specified frequency. Notch filter is based on what noise frequencies are present in the module’s operating environment.
Digital Filter
Sets the time constant for a first order lag filter that is used to smooth noise transients on the input with a range from 0...32,767 ms. When set to 0 ms, no filtering takes place.
Diagnostics
Accesses the Diagnostics dialog, which contains diagnostics information for the channel.
