The RDU40 housing shall be grounded locally to the tank. Use minimum
4 mm2or AWG 11 wire. Additional protective ground connection to the
power distribution central or the REX junction box is not recommended
except where required according to national code of practice. A ground
loop with circulating current may occur.
If a cable with two shields is used, one shield shall be connected to
ground in the REX junction box and the other shall be circular connected
inside the cable gland of the RDU40.
Check the packing and put the locking device for the weather protection
hatch in position when remounting the RDU-cover. Tighten all six screws
firmly.
Mount the RDU40 with the four M4 screws. Distances between the
screws are 60 mm and 68 mm, see Figure 1-2.
Figure 1-2. Back of RDU40.
1.1 Two RDU40 connected to the same REX
If two RDU40 are to be installed to the same REX one of them has to be
“slave” while the other is “master”. The slave cannot be configured or
controlled individually but follows the master. Only the LCD-contrast can
be individually controlled at the slave.
To make an RDU40 work as a slave it is necessary to move the jumper at
the RDU40 cover to position 2 according to Figure 1-1.

2. Device Handling
Before you can start using the RDU40 you must enable it in the REX
device, using the REX installation wizard in WinSetup (see TankMaster
WinSetup User´s Guide Chapter 3.8.4).
2.1 Operation
You can use the display panel RDU40 for viewing tank data. The four
softkeys allow you to navigate through the different menus and to select
various functions for service and viewing tank data. If you leave the
RDU40 in Service mode or Display setup mode without pushing any
buttons for a time pre-set by the user (default timeout is 2 minutes), the
RDU40 is automatically switched to View mode, presenting the default
display.
The LCD contrast can be increased by simultaneously pressing the two
buttons on the right-hand side. Press the two left-hend buttons to
decrease the contrast. It takes approximately 10 seconds to adjust from
minimum to maximum LCD contrast.
In the RDU40 for REX the user navigates in a menu system:
Figure 2-1. Menu system of RDU40.
For normal operation, only the View menu is used. It has the following
options:

2.1.1 User defined view
To see the most important parameters the user can define an own view
where up to six values can be shown, either all at the same time
(standard), one by one (toggling) or in Two rows (max three values).
Setup of a User Defined view is described below (Display setup from
RDU40 / WinSetup).
2.1.2 Single value view
The Single value view shows only one value. By default Level is set as
the value to be shown, but it can from WinSetup be changed to any other
value, described in “The single value view” on page 2-9.
2.1.3 Standard view
The Standard view always shows these six values, all at the same time:
Level, Ullage, Level rate, Signal strength, Volume and Temperature.
Figure 2-2. Standard view.
2.2 Service menu
The Service menu provides functions to check REX status by means of
a Configuration report, invoke the special commands SW Reset and
Echo Search, and perform a Test LCD to simplify visual inspection of
the display. Also there is a mode for Advanced service which is to be
used by authorised personnel only.

2.3 Setup display for User Defined view
Setup can only be made from a master RDU40. See “Two RDU40
connected to the same REX” on page 1-2.
Press the Back button until you reach the Main menu and choose
Display panel. A password is required - by default the password is blank
(just press OK) but the user can change it to prevent unauthorised users
from reconfiguring the RDU40.
Now the menu Display setup is shown. To start setup of the user
defined panel, choose User Defined and you arrive at Select items.
This is where you select which items (values) are to be shown. A
maximum of six items can be selected. If you wish to view the items in a
Two rows mode, the maximum is three. An item is selected (or
unselected) by moving the cursor down to it and then pressing the Mark
button. A tick in the corresponding square indicates the selected items.
24 items are available, of course dependent of how the REX gauge is
equipped:
Level
Ullage
Level rate
Signal strength
Volume
Average temperature
Temperature spot 1 - 6
Analog input 1-2
Vapor pressure
Liquid pressure
Vapor temperature
Observed density
Free water level
Hart slave 1-3
Relay 1-2
Press Next to continue.
The next step is to Select mode, i.e. determine how the selected items
shall be shown. Select mode by moving the cursor to the desired mode
and press the Mark button. Three options are available:

2.3.1 Standard view
In the Standard view the items are listed below each other, just as for the
Standard view mentioned above, but now the items selected by the user
will be shown.
Figure 2-3. User defined Standard view.
2.3.2 Toggling view
In the Toggling view the items selected by the user will be shown one by
one. If the Toggling view is selected the dialogue Set how long time
each item will be shown will appear. Set the time in seconds with the
arrow buttons and confirm by pressing Next.

2.3.3 Two rows view
In the Two rows view the individual status for each value is shown, such
as High, HW error and Invalid.
Figure 2-5. User defined Two rows view.
Now units corresponding to the selected items must be defined. The
RDU40 will take you through the necessary units. You select unit by
moving the cursor to it and press the Mark button. Continue by pressing
Next. One or more units may have to be defined, depending on which
items were selected previously.
The last step is to Set timeout for return to default display. This
means that if the RDU40 is left in Display setup or Service mode it will
go back to the default display after the set time. Default display is at
delivery Single value, but once a user-defined panel has been
configured, user-defined panel becomes the default display. After that,
the only way to change default display is via WinSetup.
The timeout is set in minutes by using the arrow keys. Press the Save
button and you have completed the setup of the user-defined panel.
2.4 Display setup by using WinSetup
The setup of RDU40 described above can also be done via WinSetup.
When using WinSetup you don’t have the same controlled guidance as
you would when using the RDU40. It is important to be familiar with the
system and therefore it is recommended that only service personnel use
WinSetup to setup the RDU40.

3. Troubleshooting
3.1 The RDU40 flashes a checkered pattern.
Check the following:
Bit 0 in holding register 69 set to 1 to enable display control.
The part number of the FCC card must be 9150072673b, 9150072675a
or later, otherwise the jumpers on the FCC card have to be moved to
position 1, according to picture 10. The part number is printed on a stick-
on label on the FCC card.
Figure 3-1.Jumpers on FCC card.
REX SW version is 1.D1 or later. In WinSetup, click right mouse button
on the present REX device and choose Properties. Under
Communication you can see the label Version telling the REX SW
version. REX SW version 1D.1 will give reduced functionality, according
to “Limited functionality of RDU40.” on page 3-2.
The RDU40 for REX cannot be combined with a Slave Data Acquisition
Unit (SDAU). No SDAU shall be configured in holding register 5 in
WinSetup.
All wires are connected correctly.
REX gauge shall not be in boot mode.
Make sure the RDU40 SW version is 1.B1 or later. To check you must
remove the cover on the back of the display. The SW version can be
read from a stick-on label on a PROM, according to Figure 3-2.

Figure 3-2.RDU40 SW version.
If you run the Test LCD a checkered pattern will show but the RDU40
returns to default view in less than a minute.
3.2 RDU40 LCD problem.
RDU40 shows nothing but four black rectangles in the bottom of the
LCD. Make sure that you have a master RDU40. A master RDU40 shall
have the jumper at the back of the RDU40 cover in position 1, according
to picture 1. Slave RDU40 is only used when it already has a master
RDU40 to follow.
3.3 RDU40 does not respond.
RDU40 does not respond when buttons are pressed and keeps starting
up, showing only the default view.
If you have two RDU40 connected, make sure one of them is set to be
slave (jumper in position 2, see Figure 3-1.)
3.4 Limited functionality of RDU40.
Only a few items can be shown and imperial unit is 1/8 instead of 1/16.
You may have REX SW version 1D.1. The RDU40 will work, but with
reduced functionality. To get full functionality, upgrade REX SW to 1D.2
or later.
