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 they had before accessing the menu, and the output and con-
trol 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 secon
1.11, and for a full view of the ‘conguraon menu’ structure see
secon 1.12.
‘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 1.11.5 for a list of funcons eligible for ‘fast access’ in
this instrument. The ‘Password’ (‘PASS’) funcon does not block ac-
cess 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 validat-
ing the changes.
Front key pad descripon
Key SQ (<) - press the SQ (<) key for 1 second to access the ‘con-
guraon menu’. Inside the menu, the SQ (<) key funcons as a
‘ENTER’ key. It selects and accesses the menu opon currently dis-
played. At menus with numerical value entries, it validates the num-
ber displayed.
Key UP (5) - the UP (5) key gives access to the ‘fast access’ menu.
Inside the menus, it moves vercally through the dierent menu op-
ons. At menus with numerical value entries, it modies the digit
selected by increasing its value to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Key LE (3) - inside the menus, the LE (3) key funcons as the ‘ES-
CAPE’ key. It leaves the selected menu, and eventually, will leave the
whole menu. When leaving the ‘conguraon menu’ with the LE (3)
key, the changed parameters are acvated. At menus with numeri-
cal value entries, the LE (3) key allows to select the acve digit. To
modify the value of the selected digit use the UP (5) key.
Menu ‘rollback’
Aer 30 seconds without interacon from the operator, the instru-
ment will rollback and leave the ‘conguraon menu’ or the ‘fast ac-
cess’ menu. All changes will be discarded.
1.10 How to operate the menus
Input
Example of operaon inside the
‘conguraon menu’.
1. The SQ (<) key enters into the
‘conguraon menu’.
2. The SQ (<) key enters into the
‘InP’ opon menu.
3. The UP (5) key moves through
the menu opons.
4. The SQ (<) key selects the
desired range and returns to the
‘InP’ menu.
5. The LE (3) key leaves the ac-
tual menu level and moves to the
previous menu level.
6. The LE (3) key leaves the ‘con-
guraon menu’. Changes are ap-
plied and saved at this moment.

1.11 Conguraon menu
To congure the inial set up of the instrument, select the type of
sensor to be connected to the instrument.
Access the ‘Input’ (‘InP’) menu to select the type of sensor. Opons
available are Pt100 / RTD with 2 and 3 wires, and thermocouples J, K,
T, E, S, R, N, C, L and X. Thermocouple X is a linear signal os 10 uV/ºC.
1.11.1 Inial set-up
The ‘Temperature conguraon’ (‘cnF.t’) menu allows to congure
several funcons associated to the measure and working with tem-
perature signals.
• at the ‘Degree’ (‘dEG’) menu, select ‘ºc’ to measure in Celsius
degrees, or select ‘ºF’ to measure in Fahrenheit degrees.
• at the ‘Resoluon Pt100’ (‘P.rES’) menu, select the reading res-
oluon for the Pt100 / RTD. Select ‘1º’ for 1º resoluon or select
‘0.1º’ for 0.1º resoluon.
• at the ‘Reading oset’ (‘oFFS’) menu, congure a number of
counts to be added to the reading. Applies both to the measure in
Pt100 / RTD and thermocouples. This oset allows to correct read-
ing errors associated to dierent types of probes, which can not
be corrected by other means. Oset value allows for ‘±100’ display
counts.
• the ‘Thermocouple CJC’ (‘t.cJc’) menu allows to acve or deac-
vate the automac compensaon of the thermocouple cold junc-
on. When working with a real thermocouple, compensaon must
be on. In case of using an electronic thermocouple simulator, it may
be needed to deacvate the automac cold juncon compensaon.
• at the ‘on break’ (‘on.bk’) menu select the behavior of the instru-
ment in case of sensor break detecon. Select ‘to_h’ to set reading
to overrange, or select ‘to_L’ to set reading to underrange.
• at the ‘Alpha’ (‘ALPh’) menu congure the alpha for the
Pt100 / RTD. The standard values in industry are ‘385’ and ‘390’.
• the ‘Degree symbol’ (‘ºLEd’) menu allows to light the symbol ‘º’
on display, to the right of the temperature value.
1.11.2 Temperature conguraon
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

puts up to 4 and 6 relays, see special modules R2, R4 and R6 at sec-
on 2.6. The alarm states are indicated in the front display with leds
marked as ‘1’, ‘2’ and ‘3’.
To congure an alarm, enter into the alarm menu (‘ALr1’, ‘ALr2’ or
‘ALr3’) and congure the following parameters :
• select ‘Acve’ (‘Act’) to ‘on’
• at ‘Alarm type’ (‘TypE’) select the alarm acng as a maximum
type alarm (‘MAX’) or a minimum type alarm (‘MIn’). The maxi-
mum type alarm (or minimum type alarm) acvates when the dis-
play value is higher (or lower) than the setpoint value.
• at ‘Setpoint’ (‘SEt’) enter the value for the alarm acvaon point.
This parameter is eligible for conguraon through the ‘Fast access’
menu (see secon 1.11.5).
• congure the hysteresis value at ‘Hysteresis’ (‘hySt’). The hys-
teresis applies to the deacvaon process of the alarm. The alarm
deacvates when the reading has passed the setpoint value plus
the hysteresis value. Hysteresis helps to avoid repeve switching
of the alarm relays, due to uctuang input signals around the set-
point.
• at ‘Acvaon delay’ (‘dEL.0’) congure the delay to apply before
alarm acvaon. The acvaon delay starts counng when the set-
point value is passed. Value from 0.0 to 99.9 seconds.
• at ‘Deacvaon delay’ (‘dEL.1’) congure the delay to apply
before alarm deacvaon. The deacvaon delay starts counng
when the setpoint value plus the hysteresis value, is passed. Value
from 0.0 to 99.9 seconds.
• to work with ‘windowed alarms’ (see graphical example below)
acvate ‘Setpoint 2’ (‘SEt2’) to ‘on’ and then congure the desired
second setpoint value. Second setpoint must always be higher in
value than the rst setpoint.
• the ‘Relay inverted’ (‘r.Inv’) parameter inverts the normal relay
connecons. When set to ‘on’ the relay will be acve when alarm is
inacve. For security applicaons where an inacve relay controls
the shutdown of the system.
• the ‘Locked alarm’ (‘A.Lck’) parameter disables the automac
deacvaon of the alarm. Alarm deacvaon must be performed
manually, by pressing the ‘LE’ front buon (see secon 1.11.8)

1.11 Conguraon menu (cont.)
The instrument provides several funcons associated to the reading
of the display values
• the ‘Steps’ (‘StEP’) funcon allows to dene minimum reading
steps, which will 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. It also provides a way to reset the
value. This parameter is eligible for conguraon through the ‘Fast
access’ menu (see secon 1.11.5).
• the ‘Memory of minimum’ (‘MAX’) funcon displays the minimum
reading value stored in memory. It also provides a way to reset the
value. This parameter is eligible for conguraon through the ‘Fast

The ‘On Power Up’ (‘on.Pu’) menu congures funcons to apply at
start-up. It applies only to instrument restart aer power loss. It does
not apply to instrument restart due to change in conguraon.
• parameter ‘Delay’ (‘dLAy’) assigns a waing me in seconds. The
instrument waits the congured me before starng normal func-
on. During this waing me, the display shows all decimal points
on in ash mode, all alarms are in the state dened at the ‘Alarm 1’,
‘Alarm 2’ and ‘Alarm 3’ entries, there is no signal acquision and
there is no communicaons or control being performed. Aer the
congured me is over, the instrument starts in normal funcon. De-
lay value between 0 and 200 seconds.
Applicaon - the start-up process for an automaon system implies
that dierent parts of the system (engines, actuators, controllers, ...)
have dierent start-up mes. The ‘Delay’ funcon gives me to the
instrument to wait unl the slowest part of the system is fully func-
onal before execung acons on the system (signal reading, relay
acvaon, ...)
• the ‘Alarm 1’ (‘ALr1’), ‘Alarm 2’ (‘ALr2’) and ‘Alarm 3’ (‘ALr3’) pa-

The RTU module provides a Modbus RTU communicaons module
for Series M of panel meters. The RTU module implements funcon
‘4’ (‘Read Input Registers’) of the Modbus RTU protocol, to access the
instrument registers (reading value, alarm status, memory of maxi-
mum and minimum, ...)
Conguraon from instrument front keypad, through menu entries
‘Opt.1’, ‘Opt.2’ or ‘Opt.3’, depending on the posion the module is
installed.
The RTU module can be ordered pre-installed into a Series M panel
meter, or standalone for delayed installaon, as it does not require
soldering or special conguraon.

2.8 Modules R2, R4, R6
The R2, R4 and R6 modules provide 2, 4 and 6 relay outputs for Series
M panel meters. Relays with 3 contacts each, with switching capabil-
ity up to 250 V @ 6 A.
Modules R2, R4 and R6 are installed on slot ‘Opt.1’ (see secon 1.14)
and are congured from instruments front keypad, and provide set-
point conguraon, hysteresis, independent acvaon and deacva-
on delays, and second alarm setpoint for windowed alarms.
Only one module R2, R4 or R6 can be installed per instrument. Mod-
ules R2, R4 and R6 are not compable with standard R1,T1 and SSR
modules.
The R2, R4 and R6 modules can be ordered pre-installed into a Series
M panel meter, or standalone for delayed installaon, as they do not
require soldering or special conguraon.
The S2 module provides a RS-232 communicaons module for Series
M of panel meters. ASCII protocol with ‘Master’ / ‘Slave’ architec-
ture. Addressable with up to 31 modules. Frames codied in rep-
resentable ASCII characters (codes 32 to 255), directly visible using
‘hyperterminal’ or similar programs.
• Access to display values, alarm status, memory of maximum and
minimum, alarm setpoints, ...
