54…4 CONFIGURATION…4.6.2 Analog Input ConfigurationSet the time period over which the process variable is to befiltered prior to being sampled (0 to 60 seconds).Set a tolerance level (between 0 and 100% of theengineering range) to allow for deviation of the input signalabove or below the input span before an input failure isdetected.Example – setting the fault detection level to 10% on an inputrange of 50 to 250 bar causes an 'Analog Input Failure' faultto be detected below 30 bar and above 270 bar.In the event of an input failure, recorder channels can be setto drive upscale, downscale or in the direction of failure.Upscale – channel value driven beyond full scale.None – driven in direction of failure.Downscale – channel value driven below zero.4.6.3 Digital Input ConfigurationNote. This tab is displayed only if the Source ID for this Recording Channel is a digital source – see Section 4.6.1.Enter the tag to be displayed on channel indicators when thedigital signal is active (6 characters max.) .Note. Tags with a high percentage of capital lettersand wide characters such as 'W' or 'M' may appeartruncated in some Operator Views. In such cases, use lowercase letters or fewer characters.Enter the tag to be displayed on channel indicators when thedigital signal is inactive (6 characters max.).•1 If this parameter is changed, a new internal data file for this recording channel is created. All historical data stored internally for thischannel is lost.Filter time constant In secondsFault detect level (%) 10%Broken sensor direction UpscaleDigital OFF tag FullTotalizerSet UpDigital ON tag ClosedDigital I/P•1•1 |
