1.8.1 Connecng the ‘sense’
Measuring with load cells requires a stable and accurate ex-
citaon voltage. Connecng the ‘sense +’ and ‘sense -’ termi-
nals to the load cell, provides the instrument with an accurate
value of the excitaon voltage received by the cell. Deviaons
and errors from the standard excitaon value are automa-
cally compensated by the instrument, increasing the accuracy
and reliability of the measure.
If you do not wish to use the ‘sense ’, place a shortcircuit be-
tween terminals ‘sense +’ and ‘Vexc+’, and between terminals
‘sense -’ and ‘Vexc-’.
For applicaons with mulple cells (2, 3, 4 cells or more) con-
nect the ‘sense ’ wires to the ‘electrical middle point’ of the
power wires of all the cells (see secon 1.16.4).
1.8.2 Connecng the cell to the ground
Measuring with load cells requires an electrically clean instal-
laon. When connecng the ground to the cell system, assure
that :
• the cell connecon to ground is performed in such a way
that the current to ground DOES NOT ow through the cell.

Table 2 - Technical data for the congured acquision mode
The instrument works by default with a fast acquision mode
of 16 acquisions per second, with a noise rejecon opmized
for 50 and 60 Hz frequencies. Two addional faster acquision
modes are available, opmized for noise rejecon to a single
specic frequency of 50 Hz or 60 Hz.
To opmize the noise rejecon only to 50 Hz and / or increase
the acquision speed to 50 acquisions per second, congure
the ‘Mode’ (‘ModE’) parameter to ‘50.hZ’ value. This selec-
on increases the speed to 50 acquisions per second and
increases the noise rejecon to 50 Hz, although it reduces the
noise rejecon to 60 Hz. Congure the parameter value to ‘60.
hZ’ to increase to 60 acquisions per second and maximum
rejecon to 60 Hz noise, reducing the noise rejecon for 50 Hz.
To congure the mode see secon 1.12.7.

Table 3 - Input signal ranges
1.9.2 Signal ranges
The instrument works with 6 internal signal ranges and
the acve range is automacally selected when the in-
strument is started. The selecon depends on the value
of the two parameters : ‘Sensivity’ (‘MV.V’) and ‘Excita-
on voltage’ (‘V.EXc’) (see secon 1.12.2)
Example : with a sensivity conguraon of 2.0000 mV/V
and a congured excitaon voltage of 10 Vdc, the instru-
ment selects the 20 mV input signal range, by calculat-
ing 2 mV/V x 10 Vdc = 20 mV.
The internal signal ranges available are shown below at
Table 3.
1.9.3 Number and type of cells accepted
The instrument accepts connecon for up to 8 standard
350 Ohms load cells. With a congured excitaon voltage
of 10 Vdc connect from 1 to 4 load cells. With a cong-
ured excitaon voltage of 5 Vdc connect from 1 to 8 load
cells. For load cells with dierent impedance, calculate
the current consumpon for each cell, and the total must
not exceed the maximum current the instrument can pro-
vide.
In case of problems with the power or the signal provided
by the load cells, the instrument provides three funcons
for troubleshoong purposes. These funcons allow to
access the signal input value (in mV), the excitaon volt-
age value at the ‘sense’ terminals (in Vdc) and the current
provided to the cells (in mA). The operator can use this
values to idenfy the cause of the problem. See secon
1.12.13 for more informaon on how to access this val-
ues in real me.

1.9.4 Mechanical dimensions (mm (in))
The instrument shows the value for the net weight, and can
be congured to switch reading to gross weight and the actual
value of the tare. The relaon between them is :
• Net weight = gross weight - tare
Operator can access these values by conguring the fast ac-
cess menu (key ‘UP (5)) (see secon 1.12.13).

Table 4 - Funcons included
1.10 Included funcons 1.11 ‘Tare’ funcons included
Acvate the tare funcon to force the instrument to take the
actual signal as a ‘0’ weight. The tare funcon does not mod-
ify the internal calibraon of the cell, and can be acvated as
many mes as needed. The tare funcon is typically used to
set a ‘0’ reading when a xed weight has been added to the
load cell.
Example : a truck enters a loading area and is placed on a
weighing system. The instrument indicates that the weight of
the truck is 2.500 Kg. A tare is applied to the instrument, and
now the reading is 0 Kg. The truck enters the loading area
and when it leaves, it is placed on the weighing system again.
Now the reading is 1.550 Kg. This is the weight of the mate-
rial loaded on the truck. When the truck leaves the weighing
system the instrument reads -2.500 Kg. Acvate a tare again
to force a reading of 0 Kg or wait for a new truck.
The instrument accepts dierent ways to acvate the tare
funcon:
• from the rear terminal, shortcircuit the ‘EK’ terminal against
the ‘Vexc-’ terminal. Previously, congure the ‘EK’ terminal
with the tare funcon (see secon 1.12.11).
• from the front keypad, press the front key ‘LE’ (3). Previ-
ously, congure the ‘LE’ (3) key with the tare funcon (see
secon 1.12.12).
• automacally when the instrument starts. Previously, con-
gure the ‘on power up’ funcon with the tare funcon (see
secon 1.12.14).
• automacally with the ‘auto-tare’ funcon. The inherent
mechanical characteriscs of a load cell makes the ‘zero
weight’ signal a non constant value. This can be detected
by placing and removing the same weight from a load cell,
several mes. When the weight is removed, the reading is
not always ‘0’, but a random value close and around ‘0’. The
‘auto-tare’ funcon automates the acvaon of the ‘tare’
when the reading of the instrument is stable and close to ‘0’
(see secon 1.12.14).
To avoid accidental tares, the instrument provides the ‘Max.
Tare’ (‘MAX.t’) parameter. The acvaon of the ‘tare’ func-
on, either manual or automac, is not applied if the reading
is higher than the value dened in this parameter (see secon
1.12.7).
The actual tare value can be accessed from the front key ‘UP’

The instrument has two menus accessible to the user :
‘Conguraon menu’ (key ‘SQ’) (<)
‘Fast access’ menu (key ‘UP’) (5)
Conguraon menu
The ‘conguraon menu’ modies the conguraon pa-
rameters to adapt the instrument to the applicaon needs.
To access the ‘conguraon menu’ press for 1 second the
‘SQ’ (<) key. This access can be blocked by acvang the
‘Password’ (‘PASS’) funcon. While operang the ‘congu-
raon menu’, the alarm status is ‘hold’ to the status it had
before accessing the menu, and the output and control
modules remain in ‘error’ state. When leaving the ‘congu-
raon menu’, the instrument applies a system reset, fol-
lowed by a brief disconnecon of the alarms and the out-
put and control modules. Funconality is then recovered
.
For a detailed explanaon on the ‘conguraon menu’ see
the following secons, and for a full view of the ‘congura-
on menu’ see secon
1.13.
‘Fast access’ menu
’
The ‘fast access’ menu is an operator congurable menu,
providing fast and direct access to the most usual funcons
of the instrument with a single key pad stroke. Press key
‘UP’ (5) to access this menu
.
See secon
1.12.15
for a list of selectable funcons for
the ‘fast access’ menu in this instrument. The ‘Password’
(‘PASS’) funcon does not block access to this menu. Ac-
cessing and modifying parameters in the ‘fast access’ menu
does not interfere with the normal funconality of the in-
strument, and it does not generate any system reset when
validang the changes.
Operang with the front keypad inside the menus
Key ‘SQ’ (<) - press the ‘SQ’ (<) key for 1 second to ac-
cess the ‘conguraon menu’. Inside the menu, the ‘SQ’
(<) key acts as an ‘ENTER’. It enters into the menu opon
selected, and when entering a numerical value, it validates
the number
.
Key ‘UP’ (5) - press the ‘UP’ (5) key to access the ‘fast ac-
cess’ menu. Inside the menu,the ‘UP’ (5) key sequenally
moves through the available parameters and menu entries.
When entering a numerical value, it modies the digit se-
lected by increasing its value to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
.
Key ‘LE’ (3) - press the ‘LE’ (3) key to acvate the con-
gured special funcons associated to this key. Inside the
menu, the ‘LE’ (5) acts as an ‘ESCAPE’. It leaves the select-
ed menu level and eventually, by leaving all menu levels, it

1.12.2 Inial set-up
Before starng to congure the instrument, idenfy the pa-
rameters of the load cell, at the manufacturers datasheet (see
Table 5). If the parameters are not know, leave the instrument
with the default values.
Load cell
parameters
Default values
Sensivity 2 mV/V
Nominal weight 1000 Kilos
Excitaon voltage 10 Vdc
Table 5 - Parameters of the load cell
For an accurate measure, the instrument needs to correctly
congure its parameters for the parcular load cell connect-
ed. The conguraon procedure has a rst theorecal step
and a second empirical step. The third and nal step will set
the ‘system zero’ of the instrument.
Theorecal conguraon of the load cell
The theorecal parameters are congured at the ‘Parameters
of the cell’ (‘cELL’) menu.
• at the ‘Decimal point’ (‘dP’) parameter, place the decimal
point according to the resoluon you want to see.
• at the ‘Nominal weight’ (‘LoAd’) parameter introduce the
nominal weight of the load cell. The value is entered with the
resoluon congured in the parameter above.
• at the ‘Sensivity’ (‘MV.V’) parameter, introduce the value
of the cell sensivity.
• at the ‘Excitaon voltage’ (‘V.EXc’) parameter, select 5 or
10 Vdc. (The ‘LAb’ value enables the laboratory mode, for di-
rect measure from a millivolt generator instead of a load cell
(see secon 1.16.5)).
Example : load cell with 1.95 mV/V sensivity and a nominal
value of 5 Kg and power 5 Vdc. To read in grams with a deci-
mal point, congure the theorecal parameters as indicated
below :
Decimal point : XXXXX.X
Sensivity : 1.95 mV/V
Nominal weight : 5000.0
Excitaon voltage : 5 Vdc
When the theorecal values are congured, leave the cong-
uraon menu. Apply a ‘system zero’. Force a tare, and place
dierent weights to check if the reading is correct. If it is not
correct, apply the empirical conguraon and again the ‘sys-
tem zero’.
Empirical conguraon of the load cell
The second part of the load cell conguraon is an empiri-
cal process of eld correcon. The instrument will detect and
correct the individual deviaons of this parcular load cell.
For the empirical conguraon you will need access to two
weights : a low weight, as small as possible (it can be the cell
without weight) and a high weight as close as possible to the
nominal weight of the cell.
In each case the meter will be informed of the real weight
applied to the cell in order to correct and compensate for the
measured deviaons at the signal. Both correcons are need
(high and low) for a correct conguraon of the load cell.
• low weight correcon : place the load cell without weight
or with the smallest weight possible, and access the ‘Low
weight correcon’ (‘F.Lo’) menu. Press key SQ (‘<’), intro-
duce the value of the weight and press again SQ (‘<’). The
instrument will ash shortly and return to the menu entry
‘Low weight correcon’ (‘F.Lo’).
• high weight correcon : place the load cell with a weight
closest to nominal and access the ‘High weight correcon’
(‘F.hI’) menu. Press key SQ (‘<’), introduce the value of the
weight and press again SQ (‘<’). The instrument will ash
shortly and return to the menu entry ‘High weight correc-
on’ (‘F.hI’).
Once both correcons are applied, leave the conguraon
menu. Force a tare, and place dierent weights to check that
the reading is correct. As a last step, assign the ‘system zero’ if
you want to access gross weight and net values.
Assign the ‘system zero’
This is a necessary and important step for a correct measure-
ment with a load cell.
• assign the ‘system zero’ : place the load cell without weight
or with the weight that will be considered as ‘zero’ and access
the ‘System zero’ (‘S.ZEr’) parameter. Press key SQ (‘<’). The
instrument will ash shortly and return to the menu entry
‘System zero’ (‘S.ZEr’).
The empirical conguraon of the load cell recalcu-
lates and updates the theorecal sensivity value
(‘Sensivity mV/V’ (‘M V.V’) parameter). Manual
modicaons of this parameter will modify the congura-
on of the cell. To prevent accidental modicaon con-
sider the acvaon of the ‘password’ funcon (see secon
1.12.17).
!
Once the load cell has been correctly congured,
and the reading of the instrument is correct, it is not
necessary to access again this part of the congura-
on menu. If you need to scale the reading to dierent units,
use the ‘Scale factor’ (‘ScL.F) parameters at the ‘Advanced
conguraon’ menu (see secon 1.12.7).

• at the ‘Decimal point’ (‘dP’) parameter,
select the deci-
mal point posion. Move the decimal point with key ‘LE’
(3). The posion dened will be used for all reading pa-
rameters.
Example : to read in ‘Kg’ with tenths of kilograms, place the
decimal point at ‘XXXXX.X’ and the reading will be always
be shown with 1 decimal.
Changing the posion of the decimal point will only light a
dierent decimal point led, but will not modify or re-scale
the measure of the instrument.
• at the ‘Sensivity mV/V’ (‘MV.V’) parameter, congure the
value for the load cell sensivity. Accepts any value between
0.0001 and 99.9999 mV/V. Default value is 2.0000 mV/V.
• at the ‘Nominal weight’ (‘LoAd’) parameter, congure the
nominal weight of the load cell. accepts any value between
0 and 999999. The decimal point will be shown in the posi-
on congured at the ‘Decimal point’ (‘dP’) parameter. De-
fault value is 1000.
Example : for a 5 Kg cell, congure a value of 5000 to read
in grams.
• at the ‘Excitaon voltage’ (‘V.Exc’) parameter, congure
the voltage to power the load cell. Select ‘5 Vdc’ or ‘10 Vdc’.
Default value is 10 Vdc. Select ‘LAb’ for a millivolt meter
mode in laboratory (see secon 1.16.5).
The ‘Field correcon’ (‘F.cor’) menu includes the funcons for
the empirical conguraon of the load cell. See secon 1.12.2
for addional informaon on each funcon.
• at the ‘Low weight correcon’ (‘F.Lo’) parameter, intro-
duce the real value of the actual weight at the cell. Use the
lowest weight possible, close to 0. Press key SQ (‘<’) to
start the correcon process.
• at the ‘High weight correcon’ (‘F.hI’) introduce the real
value of the actual weight at the cell. Use the lowest weight
possible, close to nominal weight of the cell. Press key SQ
(‘<’) to start the correcon process.
The ‘System zero’ (‘S.ZEr’) entry assigns the actual weight to
the ‘system zero’ of the instrument. See secon 1.12.2 for ad-

1.12.4 Funcon ‘auto-tare’
The ‘auto-tare’ funcon automacally acvates the ‘tare’
when the weight is removed from the load cell. The ‘auto-
tare’ conguraon has three parameters :
• Acvaon value : the ‘auto-tare’ funcon acvates when
reading is lower than the dened value.
• Stability band: reading must be stable, and its uctuaon
must be lower than the number of counts dened in this pa-
rameter.
• Stability me : reading must be within the stability band for
the me dened in this parameter.
When these three parameters are met (the system is ‘without
weight’ and the reading is ‘stable’) the ‘auto-tare’ funcon au-
tomacally acvates the ‘tare’.
Example : weighing system with reading from 0.0 to 2500.0
Kg. When weight is removed from the system, there is al-
ways a variable remnant value : 2.2 Kg, 3.1 Kg, -0,7 Kg, ...
This remnant value is associated to the specic imperfecons
of each load cell. Also this remnant value takes some me to
stabilize, approximately 1 second. A manual tare can be ap-
plied each me the load cell is unloaded in order to correct
this error. The ‘auto-tare’ funcon will correct it automa-
cally without operator intervenon, conguring the follow-
ing parameters.
•acvaon value = 5.0
•stability = 1.0
•stability me = 2 seconds
When reading is lower than ‘5.0’, the ‘auto-tare’ system ac-
vates, and it will analyze the stability of the signal. When
reading does not change more than ±1.0 counts for a me of
2 seconds, the tare will automacally acvate.
The ‘auto-tare’ funcon is aected by the ‘Maximum tare’
(‘MAX.t’) parameter. The instrument will not accept the ac-
vaon of the tare when reading is higher than the ‘Maximum
tare’ (‘MAX.t’) value.
The ‘Scale factor’ (‘ScL.F’) congures a xed mulplier to ap-
ply to the reading.
Example: a weighing system is congured to read in Kg, but
the system is going to be shipped to an area where measure
must be in pounds. The relaon between kilograms and
pounds is: 1 Kg = 2,20462 pounds. Within the scale factor,
congure the mulplier to 220462 and the divider to 100000.
The instrument is now congured to read in ‘pounds’.
The ‘Stock units’ (‘Stck’) funcon is provided to count large
quanes of small units, in situaons such as stock invento-
ry, recepon of goods, etc. The operator must congure the
number of ‘units’ assigned to a weight. The instrument will
measure the weight but will show the number of ‘units’.
To congure the ‘Stock units’ funcon, weight a known num-
ber of units. Then introduce the number of units, either from
the conguraon menu (‘Advanced conguraon’ \ ‘Stock
units’) or from the fast access menu (key ‘UP’ (5)).
Example from the conguraon menu : place 50 units on the
load cell, and check that the instrument is weighing correctly.
Enter the conguraon menu, and at the ‘Stock units’ (‘Stck’)
parameter, within the ‘Advanced conguraon’, introduce
‘50’ as the number of units. Save the value (key ‘SQ’ (<))
and leave the conguraon menu (key ‘LE’ (3) two mes).
The instrument restart and reads 50 units. Add more units
and observe that the reading increases proporonally to the
number of units.
Example from the front key ‘UP’ (5) : congure the func-
on ‘Stock units’ to be accessible from the front key ‘UP’ (5)’
(fast access menu) (see secon 1.12.13) and leave the con-
guraon menu. Place 50 units on the load cell, and check
that the instrument is weighing correctly. Access the param-
eter ‘Stock units’ through the front key ‘UP’ (5), and cong-
ure the number of units actually on the load cell (50 units).
Save the value (key ‘SQ’ (<)) and leave the fast access menu
(key ‘LE’ (3)). The instrument reads 50 units. Add more units
and observe that the reading increases proporonally to the
number of units
In both cases, seng a value to the ‘Stock units’ (‘Stck’) pa-
rameter assigns the value to the actual weight. The actual val-
ue of units (‘Stock units’ (‘Stck’) parameter) can be assigned
to the actual weight by pressing front key ‘LE’ (3) (see secon
1.12.12) and/or acvang the rear terminal ‘EK’ (see secon
1.12.11).
Assign the value ‘0’ to the ‘Stock units’ (‘Stck’) parameter to
disable this funcon and return to normal reading of weight.

ue and stability values to control the automac acvaon of
the tare, when weight is removed from the cell. See secon
1.12.4 for addional informaon.
• at the ‘Acvaon value’ (‘SEt’) parameter, congure the
working limits for the ‘auto-tare’. The ‘auto-tare’ only ac-
vates for lower values of reading. Accepts any value be-
tween 0 and 999999. Default value is 1000.
• at the ‘Stability band’ (‘bAnd’) parameter, congure the
number of counts allowed to consider a signal ‘stable’. The
‘auto-tare’ only acvates if the reading uctuates within this
band of counts. Accepts any value between 0 and 999999.
Default value is 10.
• at the ‘Stability me’ (‘tIME’) parameter, congure the
minimum me, in tenths of second, for the signal to be
within the stability band to consider it ‘stable’. Accepts any
value between ‘0.0’ and ‘99999.9’. Default value is ‘0.0’.
Value 0 at the stability band and/or 0.0 at the stability me,
disable the ‘auto-tare’ funcon.
The tare is automacally acvated when reading is lower
than the acvaon value, and the uctuaon of the reading
is lower than the counts dened at the ‘stability band’ for
the me dened at the ‘stability me’.
At the ‘Maximum tare’ (‘MAX.t’) parameter, congure the
maximum value of reading to allow for a tare to be applied.
See secon 1.12.4 for addional informaon. Accepts any val-
ue between 0 and 999999. Default value is 999999.
At the ‘Scale factor’ (‘ScL.F’) parameter, congure the value
for the mulplier and the divider. See secon 1.12.5 for addi-
onal informaon. Accepts any value between 0 and 999999.
Default value is 1.

of units for the actual weight. See secon 1.12.6 for addional
informaon. Accepts any value between 0 and 999999. De-
fault value is 0 (funcon disabled).

1.12.8 Alarms
The instrument manages 3 independent internal alarms, each
one controlling the acvaon of an oponal relay, transistor
or SSR control output. These outputs are oponal (see secon
2) and are installed at the free slots of the instrument (see
secon 1.18).
The instrument has three front leds that reect the state of
the three internal alarms, idened as ‘1’, ‘2’ and ‘3’. For op-
ons with 4 and 6 relay outputs, see special modules R2, R4
and R6 at secon 2.8.
• Congurable parameters
Each alarm has several conguraon parameters, starng
with the usual setpoint, hysteresis and maximum (alarm
acve when reading is higher than setpoint) or minimum
(alarm acve when reading is lower than minimum) alarm
types (see Figure 6).
• Acvaon and deacvaon delays
Each alarm can congure independent acvaon and deac-
vaon delays. These delays aect the alarm as a whole, and
the delay will aect the front led and the associated relay.
• Stability acvaon
The stability acvaon delays the alarm acvaon unl the
reading is stable (see Figure 7).
Applicaon : the lling of a tank with liquid is controlled with
a load cell. Upon reaching 5000 liters, the alarm 1 acvates to
stop the lling pump. Aer the pump has stopped, the liquid
is sll moving inside the tank, and this movement is reected
in weight and reading oscillaons. Alarm 2 is congured as
‘stability alarm’ and acvates when the liquid inside the tank
is at rest. At this moment, the tank can be removed safely.
• Second setpoint
Conguring a second setpoint creates ‘windowed alarms’.
The windowed alarm controls with a single relay output if
the reading is inside or outside the values dened (see Fig-
ure 8).
• Inverted relay
Acvate the ‘inverted relay’ funcon to invert the acvaon
logic of the associated relay.
• ‘Locked alarms’
Acvate the ‘locked alarms’ funcon to force the operator to
interact with the instrument when an alarm has acvated.
Once acvated, the alarm will remain locked at acve state,
even if the reading returns to a value below setpoint, unl
the operator manually unlocks the alarms by pressing the
front key ‘LE’ (3).

acvate the stability control of the alarm.
- at the ‘Stability band’ (‘bAnd’) parameter, congure the
number of counts that the reading can change and sll be
considered stable. Values from 0 to 999999. Default is 10.
-at the ‘Stability me’ (‘tIME’) parameter, congure the
me, in tenths of second, that the reading must be within
the ‘stability band’ to be considered stable.
Values from 0.0
to 99999.9. Default is 0.0.
• to work with ‘windowed alarmas’ congure ‘Setpoint 2’
(‘SEt2’) to ‘on’ and congure the value for the second set-
point. The second setpoint must always be higher than the
rst setpoint.
• at the ‘Inverted relay’ (‘r.Inv’) parameter, congure ‘on’
to invert the acvaon of the relay.
Relay is inacve when
alarm is acve, and relay is acve when alarm is inacve
.
• at the ‘Locked alarm’ (‘A.Lck’) parameter, congure ‘on’
to block the automac alarm deacvaon. Alarm deacva-
on must be performed manually, by pressing the front key
‘LE’ (3) (see secon 1.12.12) or rear control (see secon
1.12.11).

1.12.10 Display lters
The instrument provides several funcons to act upon the
reading in order to increase stability, reduce noise and adapt
to parcular needs. These funcons are grouped under the
‘Display’ (‘dISP’) menu and are explained below :
• the ‘Fixed digits’ (‘FIX.d’) funcon allows to x each digit
to a xed value. Typically, one or more right digits are xed
to ‘0’. Fix digits starng from the right. Value ‘-’ indicates that
the digit is not xed.
• the ‘Average lter’ (‘AVr’) applies a recursive lter upon
the reading values, in order to reduce oscillaons due to
noisy signals. Congure the lter strength between ‘0’ and
‘100’. The lter is stronger with higher values. Increasing the
strength of the lter slows the reading. Value ‘0’ disables the
lter.
• the ‘Steps’ (‘StEP’) funcon congures the reading to be
done in steps of 1, 2, 5, 10, 20 or 50 counts.
Example: congure a step of 20 and the reading will change
in steps of 20 counts (‘1420’, ‘1440’, ‘1460’, ...).
• the ‘Le zero’ (‘LZEr’) funcon lights all zeros to the le.
• the ‘Memory of maximum’ (‘MAX’) displays the maximum
reading stored on memory. To reset this memory,
select the
‘rSt’ input.
The value can be accessed through the ‘fast ac-
cess’ menu at front key ‘UP’ (5) (see secon 1.12.13).
• the ‘Memory of minimum’ (‘MIn’) displays the minimum
reading stored on memory. To reset this memory,
select the
‘rSt’ input.
The value can be accessed through the ‘fast ac-
cess’ menu at front key ‘UP’ (5) (see secon 1.12.13).

The instrument provides a digital ‘on/o’ input at the rear
terminals, referenced as ‘EK’ (see secon 1.8). Assign func-
ons to this terminal and acvate these funcons with a short
circuit between terminal ‘EK’ and terminal ‘Vexc-’. Funcons
available are explained below :
• the ‘Tare’ (‘tArE’) funcon applies a tare.
• the ‘Alarm unlock’ (‘A.LcK’) funcon unlocks all alarms
that are locked due to the ‘Locked alarms’ funcon (see sec-
on 1.12.8).
• the ‘Stock units’ (‘Stck’) funcon assigns the actual weight

The front key ‘LE’ (3) can be congured to acvate a set of
funcons. Funcons available are explained below :
•the ‘Tare’ (‘tArE’) funcon applies a tare.
•the ‘Alarm unlock’ (‘A.LcK’) funcon unlocks all alarms
that are locked due to the ‘Locked alarms’ funcon (see sec-
on 1.12.8).
•the ‘Stock units’ (‘Stck’) funcon assigns the actual weight
to the number of units dened at the ‘stock units’ parameter
(see secon 1.12.6).
In case of mulple funcons enabled, the acvaon is per-
formed sequenally in the same order as the conguraon

1.12.13 Fast access
The ‘fast access’ is an operator congurable menu. When
congured, the operator can access the most usual funcons
with a single press of the front key ‘UP’ (5). Funcons avail-
able are listed below :
• access to alarm setpoints from the front key ‘UP’ (5) al-
lows to read and modify the actual setpoint values
• access to the ‘stock units’ parameter from the front key
‘UP’ (5) allows to read and modify the actual ‘stock value’
parameter. See secon 1.12.6 for addional informaon
about the ‘stock units’ funcon.
• values for ‘gross weight’ and ‘tare’ are accessible from the
front key ‘UP’ (5) (see secon 1.9.5). To reset the tare value
visualize the value and press key ‘UP’ (5). When message
‘rSt’ appears, press key ‘SQ’ (<). The instrument returns
to visualize the ‘tare’ value. Press key ‘LE’ (3) to leave the
menu.
• funcons ‘signal mV’, ‘exc. voltage’ and ‘exc. current’
ve access to values for the input signal measured in mV,
the excitaon voltage measured in Vdc between terminals
‘sense+’ and ‘sense-’, and the excitaon current measured in
mA provided from the instrument to the load cell
These three funcons act as an integrated voltmeter and
ammeter, to be used for troubleshoong purposes, as they
give informaon on the real signals received and provided
to the load cell.
1.12.14 ‘On power up’ funcon
The ‘On power up’ (‘on.Pu’) menu allows to dene a series
of funcons to acvate when the instrument restarts aer a
power loss.
Funcons available are a delay on the acvaon of measure
and control funcons, and a tare funcon.
These funcons will acvate only aer a restart due to power-
loss, they will not apply aer a restart due to changes in con-
guraon.
Delay the measure and control funcons gives me to slow
system elements to start completely before the instrument
begins to acquire signal and control the outputs.
• access to maximum and minimum memories from the
front key ‘UP’ (5) allows to visualize the values. To reset the
maximum or minimum value, visualize the value, and press
key ‘UP’ (5). When message ‘rSt’ appears, press key ‘SQ’
(<). The instrument returns to visualize the actual memory
value. Press key ‘LE’ (3) to leave the menu
The ‘fast access’ menu is not aected by the password func-
on, allowing to have a locked access to the general congu-
raon menu, while sll some funcons are accessible to the
operator through the ‘fast access’ menu.
• Super fast access
If only one funcon is congured at the ‘fast access’ menu,
pressing the front key ‘UP’ (5) will shortly read the name of
the funcon and then automacally show into the value.
While on delay mode, the instrument shows all decimal points
lightened and ashing, all alarms are deacvated, and there is
no signal acquision or communicaons control. When the
delay me is over, the instrument starts its normal funcon-
ing.

At the ‘Key UP (‘fast access’)’ (‘K.uP’) menu congure which
funcons and parameters will be accessible through the ‘fast
access’ menu. Select ‘on’ to acvate each funcon. See sec-
on 1.12.13 for addional informaon.
• the ‘Setpoint 1’ (‘ALr1’) funcon allows to visualize and
modify the setpoint for alarm 1.
• the ‘Setpoint 2’ (‘ALr2’) funcon allows to visualize and
modify the setpoint for alarm 2.
• the ‘Setpoint 3’ (‘ALr3’) funcon allows to visualize and
modify the setpoint for alarm 3.
•the ‘Stock units’ (‘Stck’) funcon allows to visualize and
modify the quanty of units dened at the ‘stock units’ pa-
rameter (see secon 1.12.6).
• the ‘Gross weight’ (‘GroS’) funcon allows to visualize the
gross weight.
• the ‘Tare value’ (‘tArE’) funcon allows to visualize the ac-
tual tare value.
• the ‘Signal mV’ (‘c.MV’) funcon allows to visualize the
actual value of the input signal, without scaling. Value is of-
fered in mV.
• the ‘Exc. voltage’ (‘c.EXc’) funcon allows to visualize the
actual value of the excitaon voltage, measured between
terminals ‘sense+’ and ‘sense-’. Value is oered in Vdc.
• the ‘Exc. current’ (‘c.MA’) funcon allows to visualize the
actual value of the current provided by the instrument to the
load cell. Value is oered in mA.
• the ‘Memory of maximum’ (‘MAX’) or ‘Memory of mini-
mum’ (‘MIn’) allows to visualize and/or reset the actual val-
ue of the maximum and minimum memory.

block access to the ‘conguraon menu’. Acvate the pass-
word to prevent access to the instrument conguraon by
non authorized personnel. To acvate the ‘Password’ func-
on select ‘on’ and enter the code.
The numerical code is asked when accessing the ‘congu-
raon menu’ (key‘SQ’ (<)). Funcons congured to be ac-
cessible through the ‘fast access’ menu are not ‘Password’
blocked.
•at the ‘Factory conguraon’ (‘FAct’) select ‘yes’ to ac-
vate the default factory conguraon (see secon 1.14 for a
list of default parameters). The cell conguraon parameters
(‘Inial conf.’ (‘Init’) menu) are not aected by this reset if
