1.5 To access the instrument
To open the housing, remove the screws from the back
cover. With each screw there is a metal washer and a plasc
washer. Once the screws are out, remove the back cover.
The gure below shows the instrument internal structure for
a B26 format. It shows the locaon of the 3 slots for oponal
output and control modules, the power terminal and the
input signal terminal.
To close the instrument, place the back cover, the screws,
the metal washer and the plasc washer. The plasc washer
is in contact with the back cover. Conrm that the screws are
correctly turning inside the internal female screws.
To ensure a correct IP65 protecon ghten the back cover
screws with a strength between 30 and 40 Ncm, with the
help of a dynamometer screwdriver.
1.6 Modular system
Large format meters are designed with an
internal modular architecture. The output and control
modules are independent and can be installed by accessing
the internal circuits of the instrument, and connecng the
module to the connecon jumpers of the selected slot.
Each module is provided with a cable e to x the
module to the e base. The input signal modules denes the
instrument funcon and are exchangeable, switching a
temperature meter to an impulse counter only by replacing
the input signal module.
See secon 2. for informaon regarding the output and
control opons available
To install an output and control module
(1) insert the ‘module pins’ into the
‘connecon jumpers’ in one of the
free slots
(2) place the ‘cable e’ into the ‘e
base’ and embrace the ‘module’

instrument has some free space le to write the color or
local code for each cable.
7. To comply with security regulaon 61010-1, add to the
power line a protecon fuse acng as a disconnecon
element, easily accessible to the operator and idened
as a protecon device.

1.8 Control signal connecons
The connecons terminal is located in the instrument (see
secon 1.5). All control signals acvate by falling edge, by
short-circuit to 0 V. To acvate controls with other signals or
acvaon, see secon (see secon 1.14.10).
At normal connecons, the ‘start’, ‘stop’ and ‘reset’ controls
are independent.
The ‘B’ connecons acvates automacally when one of the
special ‘B’ funcons (see secon 1.14.6) is congured. The
‘start’ and ‘stop’ controls share the same terminal 3. Signal
at ‘high’ level acvates the ‘start’, and at ‘low’ level acvates
the ‘stop’. The remaining terminal is dedicated to control the
‘B’ funcon selected.

The reset funcon can be acvated from three independent
and congurable sources:
• Front reset - associated to the front key ‘LE’ (3). This
reset can be congured by menu (see secon 1.14.15). The
front reset is acvated by levels (pressed / not pressed).
• External reset - connected to pin 5 at the internal signal
terminal (see secon 1.8). It acvates by falling edge, by
connecon to the 0 Vdc terminal. To congure a dierent
acvaon see secon 1.14.10. Congurable trigger level
between 0 and 3.9 Vdc, congurable pull-up / pull-down
resistors, can be congured to work with other type of
signals (NPN, PNP, push-pull, inducve, TTL, ...).
• Alarm reset - the ‘on alarm’ parameter at alarms 1, 2
and 3 (see secon 1.14.12) can be congured to acvate a
certain funcon when alarm acvates: stop, load ‘0’, load
‘preset’.

The instrument has two menus accessible to the user :
‘Conguraon menu’ (key ‘SQ’) (<)
‘Fast access’ menu (key ‘UP’) (5)
Conguraon menu
The ‘conguraon menu’ modies the conguraon
parameters to adapt the instrument to the applicaon
needs. To access the ‘conguraon menu’ press for 1
second the ‘SQ’ (<) key. This access can be blocked by
acvang the ‘Password’ (‘PASS’) funcon. While operang the
‘conguraon 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
‘conguraon menu’, the instrument applies a system
reset, followed by a brief disconnecon of the alarms and the
output and control modules. Funconality is then recovered.
For a detailed explanaon on the ‘conguraon menu’
see the following secons, and for a full view of the
‘conguraon menu’ see secon 1.17.
‘Fast access’ menu
The ‘fast access’ menu is an operator congurable menu,
providing fast and direct access to the most usual funcons
of the instrument with a single key pad stroke. Press key ‘UP’
(5) to access this menu.
See secon 1.14.14 for a list of selectable funcons for the
‘fast access’ menu in this instrument. The ‘Password’ (‘PASS’)
funcon does not block access to this menu. Accessing and
modifying parameters in the ‘fast access’ menu does not
interfere with the normal funconality of the instrument,
and it does not generate any system reset when validang
the changes.
Operang with the front keypad inside the menus
Key ‘SQ’ (<) - press the ‘SQ’ (<) key for 1 second to
access the ‘conguraon menu’. Inside the menu, the
‘SQ’ (<) key acts as an ‘ENTER’. It enters into the menu opon
selected, and when entering a numerical value, it validates the
number.
Key ‘UP’ (5) - press the ‘UP’ (5) key to access the ‘fast
access’ menu. Inside the menu,the ‘UP’ (5) key sequen-
ally moves through the available parameters and menu
entries. When entering a numerical value, it modies the digit
selected by increasing its value to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
1.14 Conguraon
1.14.1 How to operate the menus
Key ‘LE’ (3) - press the ‘LE’ (3) key to acvate the
congured special funcons associated to this key. Inside
the menu, the ‘LE’ (5) acts as an ‘ESCAPE’. It leaves the se-
lected menu level and eventually, by leaving all menu lev-
els, it leaves from the conguraon menu. Then changes are
applied and the instrument is back to normal funcon. When
entering a numerical value, it selects the acve digit, and the
value is then modied by key ‘UP’ (5).
‘Rollback’
Aer 30 seconds without interacon from the operator, the
instrument will rollback and leave the ‘conguraon menu’
or the ‘fast access’ menu. All changes will be discarded.
Instruments with 4 and 6 digits
The conguraon menus included in this document show
values for a 6 digit instrument. In case of 4 digit instruments,
note that maximum reading values should be 9999 instead
of 999999 to 9999 and minimum reading values should be
-1999 instead of -199999.

The ‘On Power Up’ (‘on.Pu’) funcons allows to dene a
series of acons to acvate when the instrument restarts
aer a power loss. Funcons available are a delay so the
instrument waits a dened me before starng to measure
and control, an automac reset of the me counter and the
denion of the status of the counter (counng or stopped).
The funcons will apply only aer a restart due to
power-loss, they will not apply aer a restart due to changes
in conguraon.
Delaying the measure and control funcons gives addional
me to elements of the system who are slower, so they can
1.14.3 ‘On power up’ funcon
start completely before the instrument begins to acquire
signal and control the outputs.
While on delay mode, the instrument shows all decimal
points lightened and ashing, all alarms are deacvated, and
there is no signal acquision or communicaons control.
When the delay me is over, the instrument starts its normal
funconing.
El full start-up process of the instrument is as follows: waits
the me congured at ‘Delay’, resets the me counter (as
congured at ‘Reset’), starts counng or stopped, and reads
the status of the external controls ‘start’, ‘stop’ and ‘reset’.
1.14.4 Flash funcon
The ‘Flash’ (‘FLSh’) congures ashing display when the
instrument is stopped (‘StP.F’) and/or when the instrument
is counng (‘StP.F’).
The external reset can be acvated by edge or by level. Edge
acvaon means that the reset will acvate when there is
a transion from ‘0’ to ‘1’ or from ‘1’ to ‘0’. Level acvaon
means that the reset acvates at level ‘0’ or level ‘1’.
To invert the logic of the acvaon see secon 1.14.10.
1.14.5 External reset conguraon
The operator can select a special funcon (called ‘B’
funcon) to be controlled from external control terminal
3 (see secon 1.8.2). Selecng a ‘B’ funcon modies the
standard connecon of the instrument, and acvates the ‘B’
connecons in order to free one of the terminals to control
the ‘B’ funcon. Available funcons are listed below. See
also secon 1.14.8 :
• funcon B1 (‘Fnb.1’) to control counng direcon
(up or down)
• funcon B2 (‘Fnb.2’) to count events
• funcon B3 (‘Fnb.3’) to view total accumulated working
mes
• funcon B4 (‘Fnb.4’) to view exceeded mes
• funcon B5 (‘Fnb.5’) to ‘hold’ the reading
• funcon B6 (‘Fnb.6’) to control maximum an minimum
values (memories of longer and shorter mes)

acvang a ‘B’ funcon, the ‘B’ connecon also acvates
(see secon 1.8.2). The ‘B’ funcon control signal (termi-
nal 3) acvates by short-circuit to 0 V. For other acvaon
signals see secon 1.14.10 and take into account that the
‘start’ signal is now ‘start-stop’, and the ‘stop’ signal is now
the ‘channel ‘B’’ control signal.
• with the ‘B.1 control up / down’ (‘Fn.b.1’) funcon the
up or down counng is controlled through the channel ‘B’
control signal.
• the ‘B.2 events’ (‘Fn.b.2’) funcon enables an internal
events counter (0 to 999999) visible on display acvang
the channel ‘B’ control signal. Events that add ‘+1’ to the
internal event counter are :
-at ‘on alarm 1’ (‘o.AL1’) select ‘on’ to add ‘+1’ each me
alarm 1 acvates.
- at ‘on alarm 2’ (‘o.AL2’) select ‘on’ to add ‘+1’ each me
alarm 2 acvates.
- at ‘on alarm 3’ (‘o.AL3’) select ‘on’ to add ‘+1’ each me
alarm 3 acvates.
- at ‘on reset’ (‘o.rSt’) select ‘on’ to add ‘+1’ each me the
reset funcon acvates.
Applicaon - a producon process repeats every 15
minutes. Each me the chronometer reaches ‘15.00’
minutes, it acvates alarm 1 to inform the operator that
the material can be packed. Once the material is packed,
the operator manually unlocks the alarms and they cycle
restarts. At the end of the day, the operator can acvate
the ‘B’ funcon and see the total number of cycles done
during the day.
• the ‘B.3 total’ (‘Fn.b.3’) funcon enables an internal
me counter visible on display acvang the channel ‘B’
control signal. To reset the internal counter visualize
the value and acvate the reset (front or external). The
internal me counter can be congured to count the
total me the instrument has been powered, or counng,
or stopped.
- at the ‘Format’ (‘ForM’) parameter congure the visual
-
izaon format for the internal me counter. Select ‘ch.A’
to visualize with the same format as the main instrument.
- at the ‘Count’ (‘cnt’) parameter select ‘ALWS’ to count
the me the instrument has been powered, select ‘Strt’
to count the me the instrument has been counng or
select ‘StoP’ to count the me the instrument has been
stopped.
Applicaon - a manufacturing process repeats every 120
minutes. Any change in the producon process, model or
series implies a stop in the manufacturing process. The
operator can acvate the ‘B’ funcon to visualize the total
accumulated me the system has been stopped.
• the ‘B.4 exceeded’ (‘Fn.b.4’) funcon enables an
internal exceeded me counter visible on display acvang
the channel ‘B’ control signal. To reset the internal counter
visualize the value and acvate the reset (front or external).
The reset leaves the exceeded counter at ‘0’ and stopped.
The exceeded me counter can be congured to count the
total elapsed from a congured event.
- at the ‘Start’ (‘Strt’) parameter select ‘o.AL1’ to start the
exceeded counter when alarm 1 acvates. Select ‘o.AL2’
or ‘o.AL3’ to start counng with the acvaon of alarm 2
or alarm 3.
- at the ‘Format’ (‘ForM’) parameter congure the visual
-
izaon format for the exceeded me counter. Select ‘ch.A’
to visualize with the same format as the main instrument
Applicaon - a long duraon manufacturing process
repeats every 72 hours connuously without stop. At the
end of each cycle the operator must rell the consumed
material in less than 60 minutes. When a cycle is nished
the instrument acvates and locks alarm 1, starng the
exceeded counter ‘B’. The alarm acvates a signal to the
operator and at the same me acvates the visualizaon
of the exceeded me counter. The operator now can see
the elapsed since the alarm acvated.
• the ‘B.5 hold’ (‘Fn.b.5’) funcon allows to hold the
reading. The chronometer connues counng on the
background.
• the ‘B.6 max / min’ (‘Fn.b.6’) funcon allows to access
the memory of maximum and minimum me. Each
me a reset is applied, the instrument compares the
reading value with the maximum and minimum value and
updates the memory values if needed. Values can be
displayed with front (or remote) key UP (5) (see secon
1.14.14). Acvate channel ‘B’ to reset the maximum and
minimum values.
Applicaon - a producon process executes a reset signal
each me a cycle ends. At the end of the day the operator
can access the maximum and minimum memory values,
related to the longer and shorter producon cycles of the
day.

1.14.10 External controls conguraon
The instrument allows to congure the ‘start’, ‘stop’ and
‘reset’ external controls to accept dierent types of signals
and dierent acvaon signals
The default conguraon is acvaon by free potenal
contacts, with acvaon by falling edge (direct connecon
to terminal 0 Vdc). The following parameters allow to cong
-
ure the external controls to work with other type of signals:
• ‘Pulls for ‘Start’ and ‘Stop’’ (‘PuL.S’) - select ‘P.uP’ to
acvate pull-up resistors (needed for NPN sensors). Select
‘P.dn’ to acvate pull-down resistors (needed for PNP sensors).
Select ‘no’ to deacvate pulls. Selecng a pull resistors
congures the trigger level to 2,5 Vdc.
• ‘Acvaon for ‘Start’ and ‘Stop’’ (‘Act.S’) - select (‘on_h’)
to acvate the ‘Start’ and ‘Stop’ controls by rising edge.
Select (‘on_0’) to acvate by falling edge. (With ‘B’ connec-
ons acve, the aected signals are the ‘start / stop’ and
the ‘B’ funcon signals)
• ‘Pulls for reset’ (‘PuL.r’) - select ‘P.uP’ to acvate
pull-up resistors (needed for NPN sensors). Select ‘P.dn’
to acvate pull-down resistors (needed for NPN sensors).
Select ‘no’ to deacvate pulls. The trigger lievel for the
reset is xed to 2,5 Vdc.
• ‘Acvaon for ‘Reset’’ (‘Act.r’) - select (‘on_h’) to acvate
the ‘Reset’ control by rising edge. Select (‘on_0’) to acvate
by falling edge. Addionally, reset signal can be congured
to acvate by levels instead of edges (see secon 1.14.5).
In case of acvaon by levels, value ‘on_h’ acvates the
reset on high signal value, and value ‘on_0’ acvates reset
on low signal. Front reset acvates always by state (pressed
acvates the reset).
• ‘Trigger level’ (‘trIG’) - select the signal voltage level
at which the instrument will consider that the signal has
reached the acvaon level. Selectable from 0 to 31 levels,
where each level is approximately 0.128 Vdc. Trigger level is
the same for channels ‘start’ and ‘stop’. Reset channel has
a xed trigger to 2,5 Vdc. The three leds to the le of the
value reect the state (‘0’ or ‘1’) of control channels ‘Start’,
‘Stop’ and ‘Reset’.
• ‘Excitaon voltage’ (‘V.EXc’) - power provided by the
instrument to power-up the sensors (if needed) used to
control the signals ‘start’, ‘stop’ and / or ‘reset’, or to be
used as an acve signal (‘1’) for special connecons.

1.14.12 Alarms
The instrument manages 3 independent internal alarms,
each one controlling the acvaon of an oponal relay,
transistor or control SSR output.
Oponal modules (see secon 2) are installed at the free
slots inside the instrument (see secon 1.4). LDB-24 and
LDB-44 formats have 2 free slots for output and control
modules, while LDB-26 and LDB-46 formats have 3 free
slots for output and control modules.
The instrument has 3 front leds that reect the state of
the 3 internal alarms. These leds are only for local help
during installaon, as they are not appropriate for long
distance reading.
Each alarm controls the acvaon of the relay,
transistor or control SSR installed on its associated slot,
and the front led.
• Alarms in ‘repeat’ mode
With ‘repeat’ (‘rEPt’) mode the alarm acvates each
me that the chronometer reaches a mulple of the
setpoint. Alarm remains acve during the me indicated at
parameter ‘deacvaon delay’ (‘dEL.1’). Other parameters
on the ‘Alarm’ menu have no eect in this mode. This mode
is not funconal in viewing modes with tenths of second or
cents of second.
Applicaon: chronometer in ‘mm.ss’ mode with a
’repeat’ alarm and setpoint 1 at ‘15.00’. Alarm
acvates ar ‘15.00’, ‘30.00’, ‘45.00’, etc.
• Congurable parameters
• Alarms in ‘normal’ mode
In ‘normal’ mode (‘norM‘) the alarm acvates when
the reading reached the setpoint value.
Each alarm has
several parameters for conguraon, starng with the usual
etpoint, hysteresis and maximum (alarm acve when
reading is higher than setpoint) or minimum (alarm
acve when reading is lower than minimum) alarm types
(see Figure 7)
.
Each alarm can congure independent acvaon and
deacvaon delays. These delays aect the alarm as
a whole, and the delay will aect the front led and the
associated relay.
Acvate the ‘inverted relay’ funcon to invert the
acvaon logic of the associated relay.
Acvate the ‘locked alarms’ funcon will force the
operator to interact with the instrument when an alarm
has been acvated. Once acvated, the alarm will remain
locked at acve state, even is the reading returns to a
value below setpoint, unl the operator manually unlocks
the alarms pressing the front key ‘LE’ (or the remote key
‘LE’, see secon 3.1).
• ‘On alarm’ funcons
The ‘on alarm’ funcons allow to associate a funcon
to the alarm acvaon event. Funcons available are
reset to ‘0’, load the preset value, stop counng, or do
nothing. Funcons reset and preset create counng
cycles (from 0, then to setpoint, then to 0 again, ...). The
number of cycles performed can be accessed through
the fast access menu
(see secon 1.14.14)
.
• Alarm ash
The ‘Alarm ash’ (‘AL.FL’)
set to ‘on’ acvate the ash on
display when the alarm acvates To stop the ashing mode
press any of the front (or remote) keys pr change the state
of any of the external controls ‘start’, ‘stop’ or ‘reset’.

1.14.13 Alarms conguraon menu
To congure the alarm, access the alarm menu (‘ALr1’,
‘ALr2’ or ‘ALr3’) and congure the following parameters :
•
at the
‘Mode’ (‘ModE’) select ‘oFF’ to disable the alarm,
select ‘normal’ (‘norM‘) to enable the normal mode, or
select ‘repeat’ (‘rEPt’) to enable the repeat mode. The
‘repeat’ mode only needs the ‘deacvaon delay’ (‘dEL.1’)
parameter and other parameters have no eect on this
mode. The ‘repeat‘ mode is not funconal if cents or tenths
of seconds are visualized.
• at the ‘Type of alarm’ (‘TypE’) parameter select ‘MAX’
for maximum alarm (acvates when reading is higher
than setpoint), or ‘MIn’ for minimum alarm (acvates
when reading is lower than setpoint).
• at the ‘Setpoint’ (‘SEt’) parameter congure the alarm
acvaon point. Parameter value is accessible through
‘fast access’
(see secon 1.14.14)
.
• at the ‘Hysteresis’ (‘hySt’) parameter select the
hysteresis value. Hysteresis applies to the alarm
deacvaon. Alarm deacvates once the reading is
beyond the setpoint plus the hysteresis value. Hysteresis
prevents relay switching in case of signal uctuaons
close to the setpoint value.
• at the ‘Acvaon delay’ (‘dEL.0’) parameter congure
the delay to apply before the alarm is acvated. Delay
starts to count once the setpoint is reached. Value from
0.0 to 99.9 seconds.
• at the ‘Deacvaon delay’ (‘dEL.1’) parameter
congure the delay to apply before the alarm is deac-
vated. Delay starts to count once the setpoint is reached
plus the hysteresis value. Value from 0.0 to 99.9 seconds.
• at the ‘Inverted relay’ (‘r.Inv’) parameter select ‘on’ to
invert the acvaon logic of the relay. Relay is inacve
when alarm is acve, and relay is acve when alarm is
inacve.
• at the ‘Locked alarm’ (‘A.Lck’) parameter select ‘on’ to
block the automac alarm deacvaon. Alarm deacva-
on must be performed manually, by pressing the ‘LE’
front buon
(see secon 1.14.15)
.
• at the ‘On alarm’ (‘on.AL’) parameter congure the
acon to acvate when the alarm acvates. Select ‘cont’
to do nothing and connue counng, select ‘to_0’ to
load a ‘0’ on display, or select ‘to_p’ to load the preset
value on display. Selecng ‘to_0’ or ‘to_p’ congures
‘dEL.1’ to 1 second. Select ‘stop’ to stop counng.
• at the ‘Alarm ash’ (‘AL.FL’) select ‘on’ to acvate the
ash in display when the alarm is acve.
