1.6 Operation
Whenever it is connected to the electricity main, the weight repeater
comes on and tests the digits and LEDs, which light up in sequence.
After this, the program number and software release are displayed.
This is followed by flashing dashes which remain on until the repeater is
connected to the serial line. If valid data are transmitted along the serial
line, they are immediately displayed. The data remain displayed for up to
5 seconds, as determined by the time-out setting. If no other signal is
transmitted to the repeater, the central segments begin to flash once this
time has elapsed.
The type of string received can either be CB (see par. 5.3.1 on page
1-23) or EXTENDED (see par. 5.3.2 on page 1-24) and
acknowledgement is automatic.
If the string is the CB type, enter the number of decimal digits using the
SETUP switch on the board (consult par. 3.4 on page 1-18). If an
EXTENDED string is received, all the information is within the string
itself and there is no need to set anything. This string also handles the
metrological indications on the front panel of the display in the automatic
mode.
The serial interface used can be either RS232 or RS422, depending on
the connection made. The repeater automatically selects the type of
interface used, checking the lines piloted.

2. SAFETY INSTRUCTIONS
2.1 Prohibited uses
The instrument you have purchased is a weighing system and has been
designed and manufactured as such. The instrument is primarily
intended for weighing goods.
✔It is forbidden to use the terminal without taking the necessary
precautions for safe use.
✔Use of the terminal in places with potentially explosive atmospheres
or in areas where there is a risk of fire is strictly prohibited.
Any other use shall only be permitted if explicitly authorised by the
Manufacturer.
2.2 Regulations
The operating conditions for the electronic terminal are subject to the
regulations in force in the country in which the terminal is used. All use
of the terminal in conditions which do not comply with these regulations
is prohibited.

plates on the terminal.
✔Make sure that all the safety guards are in place and that the
connection cables are in a good condition and connected correctly.
✔Make sure that the terminal is connected to an electrical outlet socket
equipped with an efficient earth connection. Make sure that the line
complies with the applicable regulations. Make sure that there is no
difference in potential between the earth and neutral conductors.
✔If the terminal is to be connected to other devices (e.g. a computer or
other), these devices must be disconnected from the electricity main
before connection to the terminal.

3. DELIVERY AND INSTALLATION
3.1 Recommendations for installation
Use the supplied brackets to fix the repeater.
Avoid direct sunlight on the display if this is installed outdoors.
3.2 Connection of the terminal to the electricity main
DANGER
Check that:
✔the voltage and frequency of the electricity main
correspond to the indications on the warning plate affixed to
the terminal;
✔the mains outlet socket to which the terminal is connected
is equipped with an earth;
✔the mains outlet socket is in the immediate vicinity of the
terminal and is equipped with a disconnector switch;
✔the warning and danger plates are affixed to the casing
enclosing the instrument;
✔failing this, notify your maintenance personnel or contact
our Assistance Service directly.
Proceed in the following way to connect the terminal to the electricity
main in the correct way:
✔insert the plug of the power lead into the right power socket;
✔operate the disconnector switch.
The terminal complies with the European Directive governing
electromagnetic compatibility, however it is good practice to provide a
separate power supply line for the terminal.
RD52HL

DANGER
The power cable plug has IP20 protection.
Prepare an adequately protected connection to the electricity
main to suit the environmental conditions.
The socket must be equipped with a disconnector switch.
3.3 Serial connection
The display has a 10-pin connector with the following configuration:

3.4 Opening and closing the weight repeater to set the
switch
✔Disconnect the mains cable and serial cable from the repeater;
✔unscrew the four screws that fix the upper cover of the display using a
screwdriver;
✔remove the cover;
✔power by keeping the SETUP switch depressed: the position of the
decimal point will appear on the display. Press the switch to move the
decimal point to the four available positions (0 by default; 1, 2, 3
decimal numbers) in the cyclic mode.
✔Release the switch for 4 seconds to allow the terminal to return to the
display mode. Remember that the settings are only valid for the CB
string (see par. 5.3.1 on page 1-23). In the case of the EXTENDED
string (see par. 5.3.2 on page 1-24), the settings make no difference
and the decimal point is set automatically.
✔Close up the instrument by working through the operations described
above in reverse order.
