Page Header – Set Up Process Variable Input.
Broken Sensor Protection Drive
In the event of a fault being detected on the input, the
displayed value is driven in the direction of the mode
selected.
Select the broken sensor drive required:
NONE
–
No drive
UP
–
Upscale drive
dN
–
Downscale drive.
Note. When a broken input sensor is detected, the unit
switches to Divert Mode and turns the booster pump OFF.
Fault Detection Level Percentage,
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.
Set the value required, between 0.0 and 100.0% in 0.1%
increments.
Programmable Filter
This filters the pressure inputs, 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 value 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).
