Configuration Screens (Up/ Down arrows choose
options)
Press Select to Enter
Scrolling Option:
Allows the user to stop the main menu from
scrolling and choose 1 of 4 possible
parameters: Engineering Units (level and
interface), Current (mA), or Percentage. Select
the desired parameter and then press enter.
“Scroll” is the default parameter this option
keep the main menu scrolling. See section
“5.2 Features” for more details.
Display?
Scroll
Select Length:
THIS IS NOT THE MEASURING RANGE. This
parameter should only reflect the overall
sensor length. It can be adjusted by
incrementing and decrementing the value
and then pressing enter.
SelLngth
30.00in
Level Units:
This menu can be used to change the level
engineering units. It can be changed by
incrementing/decrementing to one of the
following units: in, ft, mm, cm, m and then
pressing enter.
LvlUnits
in
Select PV:
This menu allows the user to select the
measurement that controls the transmitter’s
current output (mA).
Sel PV
Level
This menu only appears if the interface (2 floats) option
is provided.
Select Alarm:
The following alarm settings can be chosen:
“FailHigh” = 21.00mA or greater “FailLow”
= 3.50mA
Sel Alarm
Fail High
Change Range:
This menu allows the user to change the
measuring range or span. Enter the menu by
changing the “No” to a “Yes” and press enter.
ChgRnge?
No
Select Lower Range Value (LRV):
This is the 4.00mA (0.00%) point on the
senor.
This
value
should
only
be
incremented. For example if the value is
changed from “0.00in” to “3.00in” the 4.00mA
point will shift 3.00 inches higher than the
Sel LRV
0.00 in
original point. It is recommended to leave
this at 0.00 most of the time unless a special
circumstance arises. Press enter to go the
next screen.
Select Upper Range Value (URV):
This is the 20.00mA (100.00%) point on the
sensor.
This
value
should
only
be
decremented. Changing this parameter will
change the measuring range or span of the
transmitter.
Sel URV
0.00 in
Select Damping:
This parameter is used to slow down the
reaction of the instrument in order to ignore
or average out any agitation on the process
surface that may be causing an unsteady
output. The units are fixed in seconds and
values can be from 1 to 26 seconds.
Sel Damp
1s
Rate of Change (RoC) Filter:
This parameter helps ignore erroneous
readings from the transmitter’s surroundings.
If the user knows how fast the level can
change in the vessel (i.e. inches per second)
then this parameter should be set at a rate
that the level in the vessel cannot suddenly
jump to. See section “5.2 Features” for more
details.
RoC Fltr
10.0in/s
Trim Sensor:
This menu can be used to recalibrate the
transmitter
TrmSnsr?
No
There is no need to recalibrate the instrument simply
use the “Change Range” menu and change the LRV and
URV as desired. If the need arises to use this menu then
level simulation will be required at 0 and 100 percent.
Offset (digital only):
This parameter simply adds a digital value to
the measuring range or span it does NOT
shift or move the measuring range. See
section “5.2 Features” for more details.
Offset
0.00 in
The offset will not change the 4/20mA output from its
original calibrated points. It only adds a digital scale to the
engineering units output. The offset will also be added to
the interface level when available.
