INTRODUCTION TO THE DIGIMASTER
This manual does not constitute a formal agreement.
A
ll information given in this manual is subject to
change without notice.
The DIGIMASTER brings a new phylosophy in digital panel
instrumentation which is expressed by multipurpose,
modular-concept devices providing a rich array of basic
functions and advanced capabilities.
With a fully MODULAR DESIGN, it is possible to implement a
wide variety of applications by only adding the adequate
options.
Intelligence within allows the meter to recognize the options
installed and ask for the necessary parameters to properly
function within desired margins. The paramenters related to
non-installed options are removed from the program routines.
T
he instruments CALIBRATION is made at the factory
eliminating the need for adjustment potentiometers.
Any circuit or option liable to be adjusted incorporates a
memory where calibration parameters are stored, making it
possible the optional cards be totally interchangeable without
need of any subsequent adjust.
Custom CONFIGURATION for specific applications can be made
quickly and easily through five front panel keys, following
structured choice menus aided by display prompts at each
programming step.
Other features of the DIGIMASTER family include :
•CONNECTIONS via plug-in terminal blocks without
screws and CLEMP-WAGO clips cable retention system.
•DIMENSIONS
Models Typ 9180 & Typ 9181 96x48x120 mm DIN 43700
Model Typ 9186 96x48x60 mm DIN 43700
•CASE MATERIAL UL-94 V0-rated polycarbonate.
•PANEL INSTALLATION without screws by means of single
part fastening clips.
To guarantee the meter's technical specifications, it is
recommended to recalibrate the meter at periodical intervals
according to the ISO9001 standards for the particular
application operating criteria. Calibration should be perfomed
at the factory or in a qualified laboratory.

direct access to the setpoint programming, 31
programmable logical functions and high conversion
rate @ 555 / second.
The 9181 is an instrument to measure and control with direct
indication in engineering units. The multifunction input board
allows to connect Load-Cells (mV) or Shunts to measure DC
currents, Process signals ±10V or ±20mA or lineal
potentiometer for measure distance, length etc.. The
instrument supply different excitation voltages for sensors,
24V @ 30mA, 2.2V @ 30mA, 5 or 10V @ 120mA allowing
supply up to 4 Load-Cells; This differents voltages are
selected by internal jumpers.
Thanks to its high conversion rate (555/s) can read peaks or
valley values from signal with a minimum width of 2,1 ms. An
analog output (ANA option) transmitting 200 readings per
second, an optocouplers output option (4OP o 4OPP) with a
reaction time of 2,1 ms or 2 relay or 4 relay as well as the
easy link to a PC through RS2 or RS4 serial output option
using protocolos burster, ISO1745 or MODBUS RTU with the
possibility of using a logical function that sends through RS
200 informations of variable per second. All is conferring to
the instrument very high performances.
In adition the instrument has three kind of filters that allow to
stabilize the reading with signals comming from differents
process.
A special function nr27 SAMPLE & HOLD allows to stop
during hold time the reached value during the measure as well
as the PEAK, VALLEY, PEAK-PEAK values and also the
comparison with SETPOINTS (selectable).
The basic instrument is made with main board, supply filter,
input board and display (see figure on page. 4).
The basic functions of the instrument are display of input
variables value, reading and store of peak,valley and peak-
peak of this variables as well as funtions Hold, Tare and reset

•Default configuration
As shipped from the factory, the CN2 connector allows the
TARE, MAX/MIN and RESET operations be made in the same
way as from the front-panel keyboard and incorporates one
more function: the display HOLD.
The HOLD state, which is acknowledged by the LED "HOLD",
freezes the display.
From factory the logical inputs are NPN configured.

PIN 5 (INP-5) MAX/MIN Function nº 6
The external electronics (see fig. 30.1) applied to the CN2
connector must be capable of withstanding 40V and 20mA
present at all terminals with respect to COMMON. In order to
guarrantee the electromagnetic compatibility, please refer to
the instructions given on page 10.
3.2 – REMOTE FUNCTIONS
The rear connector CN2 provides 4 user programmable optocoupled inputs NPN or PNP that can be operated from external
contacts or logic levels supplied by an electronic system. Four different functions may be then added to the functions available
from the front-panel keys. Each function is associated to one of the CN2 connector pins (PIN 1, PIN 2, PIN 4 and PIN 5)
referred to PIN 3 .
Each pin can be assigned one of the 31 functions listed on the following pages.
Fig.. 30.2 Conection
examples. PNP, NPN or
switch.

CONNECTORS
To perform wiring connections, remove
the terminal block from the meter's connector,
strip the wire leaving from 7 to 10 mm exposed
and insert it into the proper terminal while pushing
the fingertip down to open the clip inside the
connector as indicated in the figure.
Proceed in the same manner with all pins and plug the terminal block
into the corresponding meter's connector.
Each terminal can admit cables of section comprised between 0.08 mm²
and 2.5 mm² (AWG 26 ÷ 14).
The blocks provide removable adaptors into each terminal to allow
proper fastening for cable sections of <0.5 mm².

INSTALLATION
To meet the requirements of the directive EN61010-1, where the unit
is permanently connected to the mains supply it is obligatory to install
a circuit breaking device easy reachable to the operator and clearly
marked as the disconnect device.
WARNING
In order to guarantee electromagnetic compatibility, the following
guidelines for cable wiring must be followed:
-Power supply wires must be routed separated from signal wires.
Never run power and signal wires in the same conduit.
-Use shielded cable for signal wiring and connect the shield to
ground of the indicator (pin2 CN1).
-The cable section must be $0.25 mm

FUNCTION Nº1 TARE
The instrument has an internal buffer, where stores a dinamic average of 18 last readings (@555/seg), renewed every 5 ms.
The scan of logical inputs is done every 5ms. For that reason when is detected the function nr1, the value of TARE corresponds to
the average done max. 5ms before.
3.3.1 FUNCTION Nº 27 SAMPLE & HOLD
This function is useful to show and to process very quick phenomenons, holding on display and on the outputs the values
registered just at the moment of activating this function until this be deactivated.
On activating this function, the measuring values peak,valley, peak-peak and actual value are hold on display as well as analog
output, rs output and setpoints execpt if function 26 is active. View details on page.34.
In the deactivation ,peak-peak, valley and peak values are reset (see details in diagram page 34)
To get all the advantages of this function the instrument should be used without filters, delay on setpoints and to have selected
the relay function Quick. See append pag.47 and 48.
To use in "Quick" mode the way of working setpoints have to be programmed with the MENU 3B the first digit to 1 or 2 and
fourth digit to 0.
During the HOLD’s time on display is possible to show the stored values net, gross, valley, peak or peak-peak, via keyboard or
the specific logical function (nr 3, 4 or 29).

2.4 – Display configuration
After selection of the input range, it may be necessary to
scale the instrument for the particular application. For many
common applications, single slope scaling (2 points) should
be suficient to have good readings over the entire process
range. Other aplications, in which non-linear devices are used
may require linearizing the signal. This is accomplished by
scaling the meter with more than two points (see fig. 17.1)
Aplication type Nº of scaling points
Lineal function 2 points
Non lineal Up to 30 points
1./ Display range configuration.
The procedure of scaling the display consists of
programming a minimum of two points composed each by
an input (INP#) and a display (DSP#) coordinates.
When scaling the meter with two points (linear function),
they should be located near the process limits for the best
possible accuracy.
For multi-point scaling, it is recommended to use the most
possible number of points and to reduce the segment length.
The input signal values of the scaling points must be
all increasing or all decreasing. Avoid programming
two different displays for two equal inputs. The display
values can be entered in any order and even be repeated for
two or more input values.

The diagram shows all phases of the lockout routine which allows to
lockout the programming parameters and to change the safety code.
The access to this routine is accomplished by holding ENTER for
approximately 3s until the indication "CodE" appears on the display.
The unit is shipped from the factory with a safety code of "0000".
Once introduced this code, you are asked to select whether to change
it or to enter directly in the parameter lockout list.
If you decide to change the default code, after programming the new
one, the instrument returns to the run mode. You will be asked to
enter the new code before trying to access the lockout routine for the
next time.
If you decide not to change the safety code, the next step ('tot-LC')
allows to lock everything and return to the run mode (set digit to 1) or
to access the list of parameters which can be locked individually (set
tot-LC to 0).
