1.5 To access the instrument
To open the housing, remove the screws from the back cov-
er. 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 in-
put 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 from Series B are designed with an in-
ternal modular architecture. The output and control mod-
ules are independent and can be installed by accessing the
internal circuits of the instrument, and connecng the mod-
ule 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 instru-
ment funcon and are exchangeable, switching a tempera-
ture meter to an impulse counter only by replacing the input
signal module.
See secon 2. for informaon regarding the output and con-
trol 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’

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 param-
eters 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 ‘Pass-
word’ (‘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 re-
main 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 1.15.
‘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 1.13.6 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 in-
terfere 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 num-
ber.
Key ‘UP’ (5) - press the ‘UP’ (5) key to access the ‘fast ac-
cess’ 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 se-
lected by increasing its value to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
1.13 Conguraon
1.13.1 How to operate the menus
Key ‘LE’ (3) - press the ‘LE’ (3) key to acvate the cong-
ured special funcons associated to this key. Inside the menu,
the ‘LE’ (5) acts as an ‘ESCAPE’. It leaves the selected menu
level and eventually, by leaving all menu levels, it leaves from
the conguraon menu. Then changes are applied and the
instrument is back to normal funcon. When entering a nu-
merical 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.

1.13.2 Inial set-up
To congure the inial set up of the instrument, select the
sensor that is connected to the instrument, and then cong-
ure the parameters at the ‘temperature conguraon’ menu.
At the ‘Input’ (‘Inp’) parameter, select the sensor that is con-
nected to the instrument. Available opons are Pt100 / RTD
with 2 wires, Pt100 / RTD with 3 wires, and thermocouples J,
K, T, E, S, R, N, C, L and X. Thermocouple X is a linear 10 uV/ ºC
signal.
At the ‘Temperature conguraon’ (‘cnF.t’) menu, congure
the following parameters:
• at the ‘Degrees’ (‘dEG’) parameter select ‘ºc’ to read the
temperature in degrees celsius or ‘ºF’ to read in degrees
Fahrenheit.
• at the ‘Resoluon Pt100’ (‘P.rES’) parameter select ‘1º’ to
read the Pt100 / RTD with 1 degree resoluon, or ‘0.1º’ for
tenths of degree resoluon.
• at the ‘Reading oset’ (‘oFFS’) parameter introduce a
number of counts that will be directly added to the read-
ing. This value applies both to the Pt100 \ RTD and thermo-
couples. This oset allows to easily compensate for errors
due to dierent types of probes, which can not be correct-
ed by any other means. Values accepted from -100 to 100
counts of display.
• at the ‘Thermoc. CJC’ (‘t.cJc’) parameter acvate o de-
acvate the automac compensaon of the thermocouple
cold juncon. When working with real thermocouples,
compensaon must be set to ‘on’. When working with
electronic thermocouple simulators, it may be necessary
to deacvate the automac compensaon.
• at the ‘on break’ (‘on.bk’) parameter congure the be-
havior of the instrument (and thus, the alarm behavior) in
case of sensor break. Select ‘to_h’ to force the reading to
go to high level (overrange), or select ‘to_L’) to force the
reading to low level (underrange).
• at the ‘Alpha’ (‘ALPh’) parameter select the alpha for the
Pt100 / RTD sensor. The two standard industrial values are
‘385’ and ‘390’.
Press ‘SQ’ (<) for 1 second to access the ‘conguraon
menu’. For a descripon on how to operate inside the menus
see secon 1.13.1. For a full vision of the ‘conguraon menu’

1.13.3 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 instru-
ment (see secon 1.4). B24 and B44 formats have 2 free
slots for output and control modules, while B26 and B46
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, transis-
tor or control SSR installed on its associated slot, and the
front led.
• Congurable parameters
Each alarm has several parameters for conguraon,
starng with the usual setpoint, hysteresis and maximum
(alarm acve when reading is higher than setpoint) or
minimum (alarm acve when reading is lower than mini-
mum) alarm types
(see Figure 8) .
• Acvaon and deacvaon delays
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 as-
sociated relay.
• Second setpoint
Conguring a second setpoint creates ‘windowed alarms’.
The windowed alarm controls with a single relay output
if the reading is inside or outside the values dened
(see
Figure 9)
.
• Inverted relay
Acvate the ‘inverted relay’ funcon to invert the acva-
on logic of the associated relay.
• ‘Locked alarms’
Acvate the ‘locked alarms’ funcon will force the opera-
tor 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 if the reading returns to a val-
ue 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).

To congure the alarm, access the alarm menu (‘ALr1’,
‘ALr2’ or ‘ALr3’) and congure the following parameters :
• at the ‘Acve’ (‘Act’) parameter select ‘on’
• 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 1.13.6) .
• at the ‘Hysteresis’ (‘hySt’) parameter select the hys-
teresis 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g-
ure 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.
• to work with ‘windowed alarms’
(see Figure 9) acvate
‘Setpoint 2’ (‘SEt2’) to ‘on’ and then congure the de-
sired second setpoint value. Second setpoint must al-
ways be higher in value than the rst setpoint.
• 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 1.13.8) .

1.13.5 Display lters
The available funcons are:
• the ‘Steps’ (‘StEP’) funcon denes the reading to be
done in steps of 1, 2, 5, 10, 20 or 50 counts.
Example - selecng a step of 20 congures the reading to
change in steps of 20 counts (‘1420’, ‘1440’, ‘1460’, ...).
• the ‘Memory of maximum’ (‘MAX’) funcon displays the
maximum reading value stored in memory and allows to
reset this value. This parameter is directly accessible using
key ‘UP’ (5) (see secon 1.13.6).
• the ‘Memory of minimum’ (‘MIn’) funcon displays the
minimum reading value stored in memory and allows to
reset this value. This parameter is directly accessible using
key ‘UP’ (5) (see secon 1.13.6).
1.13.6 Fast access
The ‘fast access’ is an operator congurable menu. The op-
erator can access this menu with a single press of the front
key ‘UP’ (5). The congured menu entries will be accessible.
Eligible parameters to be accessed by this menu are:
• access to the alarm setpoints through the ‘UP’ (5) key al-
lows to read and modify the values.
• access to the maximum and minimum alarms through the
‘UP’ (5) key allows to read and reset the values. To reset
the memory values: visualize the value on display, press the
‘UP’ (5) key, when the ‘rSt’ message appears, press ‘SQ’
(<) . The instrument will return to the memory visualiza-
on. Press the ‘LE’ (3) key to exit his menu.
The ‘fast access’ menu is not aected by the password func-
on. This means that the conguraon menu can be password
blocked, while some congured funcons or parameters can
sll be accessible to the operator through the ‘fast access’
menu.
• Super fast access
If only a single funcon is selected for the ‘fast access’ menu,
pressing the the ‘UP’ (5) key will shortly display the funcon
name and then automacally jump to the funcon value.
1.13.7 ‘on power up’ funcon
The ‘On Power Up’ (‘on.Pu’) funcons allows to dene a se-
ries of acons to acvate when the instrument restarts aer
a power loss. Funcons available are a delay so the instru-
ment waits a dened me before starng to measure and
control, and the state of the alarms at power up. 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
start completely before the instrument begins to acquire sig-
nal 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on-
ing.
1.13.8 ‘LE’ key
The ‘LE’ (3) key at the front of the instrument can be cong-
ured to acvate several funcons. Only one funcon can be
assigned to the ‘LE’ (3) key. Eligible funcons are the alarm
unlock funcon (see secon 1.13.3).
