Fault Detection Level Percentage, Process Variable
10.0
Input
A fault level percentage can be set to detect a deviation
above or below the display limits, e.g. If set at 10.0%, then
if an input goes more than 10% above full scale value or
more than 10% below zero value, a fault is detected.
On some ranges the input circuitry may saturate before the
fault level set is reached. In this case an error is detected at
a level below that which is set.
Control actions and control outputs in the event of a fault
are programmable – see below.
Set the value required, between 0.0 and 100.0% in 0.1%
increments.

Default Control Output
0.0
Set the default output value required in the event of a fault,
between 0.0 and 100.0%.
Programmable Filter
0
This 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 value required, between 0 and 60 in 1 second
increments.
Mains Filter
Set the frequency of the mains supply used (50 or 60Hz).
