USER WARNINGS
RECOMMENDATIONS FOR THE PROPER USE OF WEIGHING INSTRUMENT
- Keep away from heat sources and direct sunlight
- Repair the instrument from rain (except special IP versions)
- Do not wash with water jets (except special IP versions)
- Do not dip in water
- Do not spill liquid on the instrument
- Do not use solvents to clean the instrument
- Do not install in areas subject to explosion hazard (except special Atex versions)
RECOMMENDATIONS FOR CORRECT INSTALLATION OF WEIGHING INSTRUMENTS
The terminals indicated on the instrument’s wiring diagram to be connected to earth must
have the same potential as the weighed structure (same earthing pit or earthing system). If
you are unable to ensure this condition, connect with an earthing wire the terminals of the
instrument (including the terminal – SUPPLY) to the weighed structure.
The cell cable must be individually led to its panel input and not share a conduit with other cables;
connect it directly to the instrument terminal strip without breaking its route with support terminal
strips.
Use “RC” filters on the instrument-driven solenoid valve and remote control switch coils.
Avoid inverters in the instrument panel; if inevitable, use special filters for the inverters and separate
them with sheet metal partitions.
The panel installer must provide electric protections for the instruments (fuses, door lock switch
etc.).
It is advisable to leave the equipment always switched on to prevent the formation of condensation.
MAXIMUM CABLE LENGTHS

hours to fully charge the battery.

ELECTRICAL CONNECTIONS
BASIC INFORMATION
- It is recommended that the power supply negative pole be grounded (WDESK-D, WINOX,
WTAB: connect the earthing system to the dedicated external terminal ).
- Connect terminal “– SUPPLY” to the RS485 common of the connected instruments in the event
that these receive alternating current input or that they have an optically isolated RS485.
- In case of an RS485 network with several devices it is recommended to activate the 120 ohm
termination resistance on the two devices located at the ends of the network, as described in the
paragraph RS485 SERIAL CONNECTION.
- E/EC option (if available): selects 12 groups of 5 setpoint.

If the RS485 network exceeds 100 metres in length or baud-rate over 9600 are used, the network
must be terminated at its ends:
- connect a 120 ohm resistor between the ”+” and “–“ terminals of the line, on the terminal strip of
the instrument;
- close the RS485 termination jumpers on the furthest instrument (if present), otherwise connect a
120 ohm resistor on the terminal strip of the instrument.

OUTPUTS AND INPUTS CONFIGURATION
MENU + ESC →:
The outputs are set as follows by default:  / 
Possible operation modes:
-  (normally open): the relay is de-energised and the contact is open when the weight is
lower than the programmed setpoint value; it closes when the weight is higher than or equal to
the programmed setpoint value.
-  (normally closed): the relay is energised and the contact is closed when the weight is
lower than the programmed setpoint value; it opens when the weight is higher than or equal to
the programmed setpoint value.
- : the contact will switch on the basis of gross weight.
- : the contact will switch on the basis of net weight (If the net function is not active, the
contact will switch on the basis of gross weight).

- : connecting the E/EC option you can program 12 groups (classes) of different setpoint
values; otherwise you can only set the first class. The E/EC position selects the valid relay
release values.
-  (from 0 to max full scale; default: 0): setpoint, weight value above which contact switching
occurs. The type of switching can be set (see section OUTPUTS AND INPUTS
CONFIGURATION).
MENU →:
-  (from 0 to max full scale; default: 0): hysteresis, value to be subtracted from the setpoint
to obtain contact switching threshold for the decreasing weight. For example, with SET = 100
and hysteresis = 10, switching occurs at 90 for the decreasing weight.
ALARMS
- : no serial port set as .
- : communication problems between transmitter and receiver; check instrument electrical
connections and settings.
- : maximum displayable value exceeded (value higher than 999999 or lower than -999999).
- : the weight display exceeds 110% of the full scale of transmitting instrument.
- : in transmitting instrument the  protocol has been set; change it to  protocol.
- : in transmitting instrument the  protocol has been set; change it to  protocol.

RECEIVING PROTOCOL
The following string is received from the transmitting instrument:
&NxxxxxxLyyyyyy\ckckCR
where: &= 1 character of string start (38 ASCII).
N= 1 character of net weight identification (78 ASCII).
xxxxxx = 6 characters of net weight or PEAK if present (4857 ASCII).
L= 1 character of gross weight identification (76 ASCII).
yyyyyy = 6 characters of gross weight (4857 ASCII).
\=1 character of separation (92 ASCII).
ckck = 2 ASCII checksum characters calculated considering the characters between
“&”and “\”excluded. The checksum value is obtained from the calculation of XOR
(exclusive or) of the 8-bit ASCII codes of the characters considered. This obtains a
character expressed in hexadecimals with two digits that can have the values from “0” to “9”
and from ”A” to “F”. “ckck” is the ASCII code of the two hexadecimal digits.
CR = 1 character of string end (13 ASCII).
In case of negative weight, the first character on the left acquires the value “–” (minus sign - ASCII 45).
In case of weight value is under -99999, the minus sign (“-”) is sent alternated with the most
significant figure.
In case of error or alarm, the 6 characters of the gross weight are substituted by an error
message (see section ALARMS on transmitting instrument manual).
