1. OVERVIEW
1.1 Introduction to model DM4500U
The DM4500U mode is a digita mu tifunction instrument which
a ows the user to program the input as a:
- PROCESS INPUT (V, mA)
- LOAD CELL INPUT (mV)
- Pt100 INPUT
- THERMOCOUPLE INPUT (J, K, T)
The basic instrument is a so dered assemb y composed of a main
board, a tricolor programmable display and a power circuit.
Standard features of the basic instrument inc ude the reading of the
input variab e as we as remote ho d, reading and memorisation of
max and min va ues (peak/ va ey), tare and reset function, and a
fu comp ement of programmab e ogic functions.
In addition, a variety of output options can be insta ed at the
factory from the ist be ow :
COMMUNICATION

OPT4500/4R (4 Re ays SPST 5A)
OPT4500/NPN (4 NPN output)
OPT4500/PNP (4 PNP output)
A the output options are opto iso ated from input signa and power
supp y.
This instrument conforms to the fo owing community
standards: 89/336/CEE and 73/23/CEE
Warning: Refer to the instruction manua to preserve
safety protection.

Programming instructions
The Instrument is programmab e via the front pane keyboard
and a ows access to severa independent programming menus
for configuration of the input, the disp ay and the ogic
functions. If additiona options are insta ed (seria outputs,
ana ogue output and re ays output) once recognised by the

Programming the instrument.
First, connect the instrument to the corresponding supp y;
automatica y, a disp ay test wi be done and the software version
wi be shown, then the instrument wi go to run mode.
Next, press the key to enter into the programming mode;
the indication "-Pro-" wi appear on the disp ay.
ow to store programmed parameters?
To save the changes that have been programmed, the operator
must comp ete the programming of a the parameters contained in
the current routine. In the ast step of the routine, by pressing the
key, “StorE” wi be disp ayed and a changes are stored in
memory. Then the instrument wi return to the run mode.
ow is programming routine organised?
Programming software is composed by a number of menus and
submenus. In the diagram be ow, beginning with indication "-Pro-",
press repeated y to get access to programming menus. B ocks
3, 4 and 5 re ate to output options and wi on y be shown if the
option is fitted.
Se ecting one menu, access to the different programming
submenus is done by pressing .
Modu e se ection eve

Access to programmed parameters
Because of the menu structure, the programming routines a ow
access to change one parameter without passing through the who e
ist of parameters.
To advance through programming
Progress through programming routines is done by pressing
key.
In genera , push key a certain number of times to se ect an
option and push key to va idate the change and to go forward
to the next step of the program.
The numerica va ues are programmed digit by digit as exp ained in
the next paragraph.
Programming numerical values
When the parameter is a numerica va ue, the disp ay wi show the
first digit to be programmed f ashing.
Digit selecting: Press repeated y the key to shift from eft to
right over a the disp ay digits.
Changing the digit value: Press the key repeated y to
increase the va ue of f ashing digit unti it has the desired va ue.
The minus sign is programmed depending on the variab e type. A
variab e that represents the va ue of an input wi be ab e to take a
va ue in the range -19999 to 99999, without taking into account the
decima point. When changing the first digit, this shows va ues from
(0) to (9), and then (-1), (-), and comes back to show va ues from
0 to 9.
A variab e that represents a disp ay va ue wi be ab e to take a
va ue in the range -19999 to 99999, without taking into account the
decima point. In these case the first digit shows 0, 1, -1 or -.

possibi ities, the key a ows you to browse through the ist of
options unti you find the desired parameter.

3.2 – Programming of Load cell input
Refer to ce manufacturer’s documentation, particu ar y with
respect to the ce sensitivity and supp y vo tage specifications.
As oad ce indicator, the meter’s function is to measure forces
(weight, pressure, torque...) app ied to a sensing e ement
connected to severa bridge type transducers, such as oad ce ,
which supp y signa eve s up to ±150 mV.
The two excitation vo tages supp ied by this instrument are 10 V
and 5 V. The se ection is rea ised through the configuration of the
interna bridge excitation (see diagram be ow). This way up to 2
ce s can be connected in para e with 10 V excitation and up to 4
ce s with 5 V excitation, without need for an externa source (see
connection (Sec. 3.2.1)).
Examp e:
2 ce s with 2 mV/V output are supp ied with an excitation
vo tage of 10 V; the vo tage generated by each ce at fu
oad is 20 mV. Therefore 20 mV is the maximum output as
the ce s are connected in para e . In the same case but
with a 5 V excitation, the maximum vo tage generated wi
be 10 mV.
Software configuration requires programming of the input mV range
which can be se ected from a choice of 3 ranges to avoid ‘out of
range’ signa s. There are three ranges: ±15 mV, ±30 mV and ±150
mV
Examp e:
If a weighing process gives 12 mV to the meter input with
maximum oad, the best input range to se ect wi be "15 mV".

3.3 - Programming of Pt100 input
When configuring the meter as thermometer for 3 wires Pt100
sensors, the temperature ranges and reso ution avai ab e are:
Input Range (res. 0.1 º) Range (res. 1 º)
(-100.0 to +800.0) ºC (-100 to +800) ºC
Pt100 (-148.0 to +1472.0) ºF (-148 to+1472) ºF
The Pt100 software menu a ows se ection of temperature units
(Ce sius or Fahrenheit), reso ution (degree or tenth of degrees) and
a disp ay offset. Provision is made to a ow for a sensor offset. If
there is a difference between the temperature under measurement
and the temperature read by the sensor, this can be corrected by
programming an offset from -9.9 to +9.9, with 0.1 º reso ution, or
from -99 to +99, with 1 º reso ution. LED ‘TARE’ will light up
each time that an offset value is programmed.
Examp e:
In a process of temperature contro the Pt100 sensor is
ocated in a part of the process where temperature is 10
degrees be ow than in the point in where the contro has to
be done. By programming an offset of 10 points, with 1
degree reso ution, the deviation wi be corrected.
Configurab e parameters for this input are:
a) Reading units in degree Ce sius "ºC" or Fahrenheit "ºF".
b) Reso ution in tenth of degrees "0.1 º" or in who e
degrees "1 º".
c) Offset. Offset va ue is programmab e up to ±9.9 º with
tenths reso ution, or up to ±99 º with degree reso ution.
The instrument comes from the factory with offset=0
After entering these parameters, the disp ay range and inearization
are adjusted automatica y.
