If an input failure occurs, the input value can be configured to drive in a set direction.
No action taken.
If the value of failed input is below Eng Low (see page 46), the input value is driven to
minimum downscale value; otherwise it is driven to the maximum upscale value.
The input is driven to the maximum upscale value.
The input is driven to the minimum downscale value.
The input is averaged over the time set.
Sets a tolerance level (in % of engineering range) to allow for deviation of the input signal
above or below the engineering range before an input failure is detected.
These 2 parameters enable fine tuning of the inputs to eliminate system errors. Apply a
known input value and adjust until the required input value is displayed. Normally, Zero
Adjustment is used with input values close to Eng Low (perform adjustment by applying
an offset to the reading) and Span Adjustment is used with values close to Eng High
(perform adjustment by applying a multiplier to the reading).
Resets the selected Zero / Span Adjustment parameter.
