6. Security rules
To avoid electrical shock, scale or other connected
peripheral devices damage, it is necessary to follow the
security rules below.
To supply the scale use power outlet with protective contact (not for
scales with external feeder).
Repairs and essential scale regulations can be made only by authorized
personnel.
To avoid fire risk use a feeder of an appropriate type (supplied with a
scale). Pay attention that supply voltage is compatible with specified
technical data.
Do not use a scale when its cover is opened.
Do not use a scale in explosive conditions.
Do not use a scale in high humidity.
If a scale seems not to operate properly, plug it out of the mains and do
not use it until checked by authorized service.
7. Rules proceeding with used up scales
According to obligatory rules concerning environment
protection used electronic devices should not be put in
a container with normal waste.
After exploitation used scale should be given to special units authorized to
collect used electronic equipment or to the place where the device was
bought.

USER MANUAL ME-01 11
8. Assembly and connecting external devices
1. To build a scale basing on ME-01 indicator contact authorized manufacturer
service point or use Installation Guide delivered with the indicator (other
brochure).
2. The manufacturer gives a full guaranty for ME-01 indicator only when the
indicator was mounted by AXIS Sp. z o.o. In other cases the guaranty obligation
is taken over by the final contractor of the weighing device.
To comply CE marking requirements, for connecting the wires use filtering core
20mm.
The core should be placed within 30mm from the place of its connection.
Single strain gauge scheme inside ME-01:
When 6-wires connection of strain gauge transducers is used (REF+ and REF)
jumpers shown on the picture above should be soldered out from the main board
(load cell wires are connected EXC+, EXC-, IN+,IN- and additionally REF+ and
REF-).
Commonly used wire colors:
EXC+ red
Before connecting the sensors to the indicator unplug the device from the
mains to avoid damaging the indicator.

IN+ green
IN- white
REF+ brown
REF- yellow
3. Connect the external devices cables to the meter sockets.
Diagram of common wires and shields in the platform balances:
Caution: The galvanic connection of sensors and adder housing is necessary.
All devices should be powered from the same line (phase) 230V.

9.1 Transmitter connection
P1-P3 (THRESHOLDS) outputs are used to connect dosing or signalling (option)
devices. There are opto-isolators of an open collector type with 100mA / 24V
maximum load. They can be connected directly to transmitters inputs or to
MS3K/P board offered by AXIS separately or in ST 3K/P control box (3
transmitters, own power supply).
In ME-01/A connection THRESHOLD is placed on indicator’s housing. In
ME-01/N meter connection is placed on conductor.
Optional indicators outer wires have digital markers.

Outputs are adapted for direct connection RM96P transmitter of DC24V input
voltage and AC250V 8A output. Transmitter’s coil has to be secured with diode
e.g. 1N4148.
It is recommended to use MS 3K/P electronic board (3 transmitters of RM96P
type –max. load of 3A/250V) or complete ST 3K/P control box (feeder, 3
transmitters like above).
The way THRESHOLD outputs work is described in the separate document
(Special functions description).
9.2 External key connection
The input of external keys allows to place (make double) selected scale keys into
control box or operator’s workstation. As a standard the input is taken out with a
wire for direct connect to a control panel. ME-01 indicators can be equipped with
external key interfaces (as an option on demand).

External key connecting is shown below. It is crucial to use external supply (24V)
in order to make current flow through scale transoptor input. This way of
connection provides galvanic separation of the scale from automatics system
which increases resistance to external interference and increases reliability.

9.4 Connecting a computer, printer or label printer
The scale is equipped with RS232C, which can be used to connect external devices such as computer or
a printer.
When cooperating with computer, the scale sends weighing result after initialize signal from computer or
after pressing key on the scale.
When cooperating with a printer data is send automatically after result stabilisation, but next transmission is
possible after removing previously weighted sample.
When cooperating with label printer after pressing key, the scale sends instructions set for the label
printer. Label number 0001, hour, data (if the clock is installed and on) and nett weight. During transmission
LabEL communicate is displayed.
The way of sending data and transmission parameters is set using SErIAL special function.
Set of send data is set using special function PrInt.
The following data can be send:
-Header (scale type, Max, d, e, serial number),
-Operator identification number,
-Successive printout number (measurement),
-Identification number or product bar code,
-Number of pcs (PCS function only),
-Single detail mass (PCS function only),
-Nett weight,
-Tare (package mass),
-Gross weight,
-Total mass (Total function only).
If the scale is equipped with two serial joints Print function is set independently for both interfaces.
Computer must have a special program for cooperation with data from a scale.
Dedicated programs are also offered by AXIS.
Except RS232C joint, the scale can be equipped with USB or Wi-Fi interface.
Needed controllers and instruction can be found on a CD supplied with Axis scales.

USER MANUAL ME-01 19
9.5 Detailed LonG protocol description
Standard communication parameters: 8 bits, 1 stop bit, no parity, baud rate 9600bps,
After using key, measurement data is send together with text description (NET, TARE, GROSS) –all
set by using Print option. If Print isn’t set then only scale indication is send (as below).

Attention:
Network number different than zero (SErIAL / nr function) changes scale working mode: communication
with a computer is possible after logging the scale in with 02h scale number command. To log the scale out
use 03h command.
For example: Using a program to test RS232 interface ( program is available in www.axis.pl / programy
komputerowe ) for scale number 1 please write: $0201 to log in, then SI, and write: $03 to close
communication.
