Before you begin
Before replacing your digital transmitter electronics, make sure that it
is programmed with the transmitter data restore file you created after
initial installation and calibration of your transmitter.

Note:
Each transmitter requires its own restore file.
To install the transmitter setup software, go to the section titled•
“Software installation and configuration; Modbus and DDA”.
To create a restore file, go to the section titled “• Create the transmit-
ter data restore file”.
If your transmitter electronics PCB is already programmed and you•
have a data restore file, go to the section titled “Replacing your
transmitter electronics PCB”.
Create the transmitter data restore file
Obtain the setup software that shipped with your transmitter or go to
www.mtssensors.com and download the latest Modbus or DDA setup
software from the MTS software Vault. You will be asked to register
for a login and password to enter the Vault portal. From the Vault, do
the following:
For Modbus configuration, download Modbus_*.zip
For DDA configuration, download DDA_*.zip
Perform the following steps to extract and install the setup software:
Locate and double-click the appropriate1. protocol_*.zip file. Extract
the program folder into C:\ProgramFiles\ and double-click the *.exe
file to install the program.
Create shortcut and Enable factory mode:2. Go to C:\ProgramFiles\MTS

folder to your desktop.
Right click the Configuration folder shortcut icon, select “3. Proper-
ties”. The shortcut properties dialog box opens (Figure 1).

Removing the transmitter electronics boards
Complete the following steps to remove and replace your transmitter
electronics board after you have successfully created a data restore
file.
Caution:
Ensure that all power is disconnected and that all lockout procedure(s) are
followed prior to opening the transmitter instrument housing.
Remove any dirt, debris, or liquid from the top of the instrument1.

Remove the existing transmitter electronics by unscrewing the four4.
retaining screws and removing the (top) board. Note the orientation
of boards housing before removal to aid in installation of replace-
ment boards (Figure 4).

Unscrew four standoffs and remove bottom board (5. Figure 5).
Disconnect the white sensing element (SE) 6-pin connector from6.
the bottom board (pull straight out) and remove the white DT ribbon
cable connector with a small green connector card if present (slide
wing outward and pull connector out parallel to the PCB sideways)
(Figure 6).

Use the same procedure and adhere to the same cautions noted in the
board removal process when reinstalling boards. Install the boards in
the following order:
Reconnect the sensing element (SE) connector and DT connector1.
(when available). Before you reconnect the DT to the board, verify
that the gold DT connector pins are facing down. Push wing back in
lock the DT cable.
Install the new base board (round edges) with four standoffs2.
(replacement standoffs included).
Install top board and secure with four screws (replacement screws3.
are included with kit). Verify that the orientation of the boards
are such that the connectors are all located on the same side as in
(Figure 4).
Plug the wired connector into the PC board terminal block.4.
Reattach the transmitter instrument housing cover.5.

Attention:
To avoid component damage, removing the SE with needle nose pliers is
required. Please note that the SE can not be bent in less than a 2 foot radius
(Figure 9).

the pipe. Remove the white base cartridge from the SE. To avoid
damaging the SE, do not bend the SE in less than a 2 ft. radius
(Figure 9).
Attention:
Damage to the SE and DT can occur when removing the plastic base
cartridge and heat shrink tubing from the SE (Figure 8).

Locate and open the• Gradient Off tag which is attached to the new
SE. Record the gradient information and place it in a safe place. The
Gradient value will be entered into the configuration software Fac-
tory tab window after installation (Step 5 in next section).
Remove the black rubber plug from the end of the new SE.•
Install the SE. There are two methods you can use to install the5.
SE:
Roll the SE off the spool and directly into the pipe.•
Uncoil the SE and gently feed it into the pipe by hand.•
Light pressure and twisting may be required to install the SE into
the pipe. If the SE is bent or kinked, functionality and or breakage
will occur which will render the SE unrepairable.
Secure the SE with the retaining clip you removed in step 2 and6.
reconnect the pipe to the instrument housing. Continue with
“Replacing the transmitter electronics boards”.
Attention:
If PC boards are in the housing, be sure you disconnect the SE and
DT cables first. When removing the pipe from the housing, damage
to the DT cable SE connections may occur if proper care is not taken
(Figure 7).
