The following procedures must be executed by authorized personnel.
All the connection must be executed with the device offline and turned off
It’s important to report these data when requesting info or instructions regarding the device, more-
over it’s important to report the software version number and the release number (on the cover of
the operating handbook or shown at device startup).
WARNING
DEVICE ID TAG

The device is powered thru connectors 23 and 24.
The power cable must be kept aside from cables with different voltage, from the loading cells
cables and from those for the logic input/output.
The internal circuitry is fully insulated from the power voltage.
Voltage : 24 Vdc/ 10 % max 3W
CONNECTORS
23. + Alim.
24. 0
The cell’s (or cells) cable must not be kept in other cable’s conduit (i.e. output connected with
power cables or circuit breaker), but it must follow its own path.
If cable extensions are needed these are to be safely shielded, taking note of the color code
and the cable type stated from the device’s builder. The extension’s connection must be execu-
ted via soldering machines or via links or with a junction box that can be ordered aside.
The cable must have a number of connector not higher than the ones used (4 or 6). If more connectors
are present, link the remaining to –cell power (link 2).
No more than 4 350-ohm cells can be connected to the device. The voltage is 4 Vcc and is shielded from
temporary shortages.
The device field measure needs the use of loading cells with an accuracy between 1 mV/V and 2.5 mV/V.
The cable has to be connected to the terminals from 2 to 7 on the 7-pole extractable terminal. In the case
of a 4-connector cable, the terminal to be connected are the following (2-5 3-4).
Connect the cable shielding to terminal 1.

LOGICAL INPUT CONNECTION
Both the logical input are shielded from the internal circuitry with an optoisolant.
The connection cable for the logical input is to be kept aside from power cables.
It has to be the shorter possible.
To activate a logical input it has to be linked to the positive end of a 24Vcc output while the
common connector is linked to the negative.
In the following diagram there 2 types of connection using a button on input 2 and a circuit breaker on input
1.
RELE’ OUTPUT CONNECTION
Both output are connected to a common via relè. Every connection has a voltage of 24 Vcc/Vac 1 A.
RQ: Device InstallationPag. 5
SERIAL RS485 LINKUP (OPTION)
This cable has to be kept aside from the others (power cables or cables connected to a
circuit breaker), and has to keep its own path.

SERIAL RS232 LINKUP
To get a serial connection a shielded connection cable must be used, linking to mass the
shield at one of the ends. In the case that the cable should have more connectors than nee-
ded, the unused ones should have to be connected to the shielding material.
The serial connection cable must have a maximum lenght of 15 meters (as per EIA RS-
232-C rules), if the lenght is over that measure the device Rs422 interface must be used.
This cable must be set aside from others cable (power cables or the one connected to circuit breaker),
and it should follow a path on its own.
The personal computer used for the connection must be EN 60950 compliant.
The following is the diagram for the connection with a PC 9-poles connector:

ANALOG OUTPUT LINK UP
The device has two analog output one for the low frequency the other for the high.
Data:
Analog output high voltage: range between -10 and 10 Volt or between -5 and 5 Volt, minimum load 10K
Analog output low voltage: range between 0 and 20 mA or between 4 and 20 mA, maximum load 300 .
With a factory reset it is possible to have an output 0-10V or 0-5V.
To get the connection a shielded cable must be used, One of the end must be put to
ground.
Analog transmission can be disturbed by electo magnetic pulse. The cables must be shor-
ter as possible and directed on a path of their own.

PROFIBUS LINK UP (option)
DSUB-9P male connector for the PROFIBUS cable
When this option is present the device is equipped in the lower side with a field bus PROFIBUS DP connec-
tor.
Data:
PROFIBUS baudrate from 9.6 kbps to 12 Mbps.
To get this connection a PROFIBUS cable must be used.
For the link up the file HMS_1810.GSD (given with the device) must be present on the
PLC/LC.
PROFIBUS LINE LINK UP
WARNING: if PROFIBUS connection is present, there can be no RS485 output.
DEVICENET LINK UP (opzionale)
