Decimal Point
Set the decimal point position required for
range low values.
Engineering Range Low
Set the minimum engineering (display) value required,
Note. The value set must be within the limits detailed in
opposite.
Broken Sensor Protection Drive
In the event of a fault being detected on the input and/or if the
exceeded (see next frame), the process variable is driven in the direction of the drive selected.
Select the broken sensor drive required:
NONE – No drive
UP – Upscale drive
dN – Downscale drive.
Fault Detection Level Percentage
A fault level percentage can be set to detect a deviation above or below the display limits.
For example, if set at 10.0%, then if an input goes more than 10% above
or more than 10% below
Engineering Range Low
On some ranges the input circuitry may saturate before the fault level set is reached. In this case
an error is detected below the level set.
Set the level required, between 0.0 and 100.0% of engineering span (range low to high) in 0.1%
increments.
Note. If an input exceeds the minimum or maximum value for the linearizer selected an
error is detected regardless of any fault level.
Programmable Filter
Filters the process variable input, i.e. if the input is stepped it smooths the transition between
steps and may also be used for some degree of cleaning of noisy inputs. The filter time represents
the time a step in the input takes to change the displayed process variable from 10 to 90% of the
step.
Set the value required, between 0 and 60 in 1 second increments.
