Magtrol AN 2000 CInstruction Manual
INTRODUCTION TO THE AN SERIES
This manual does not constitute a formal agreement.
All information given in this manual is subject to
change without notice.
The AN SERIES brings a new philosophy 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 adequat
e
options.
Intelligence within it allows the instrument to recognize th
e
options installed and ask for the necessary parameters to
properly function within desired margins. The parameter
s
related to non-installed options are removed from th
e
program routines.
The instrument’s CALIBRATION is made at the factor
y
eliminating the need for adjustment potentiometers.
Any circuit or option liable to be adjusted incorporates a
memory where calibration parameters are stored, making i
t
possible the optional cards be totally interchangeable withou
t
need of any subsequent adjust.
Custom CONFIGURATION for specific applications can b
e
made quickly and easily through five front panel keys,
following structured choice menus aided by display prompt
s
at each programming step.
Other features of the AN family include:
•CONNECTIONS via plug-in terminal blocks withou
t
screws and CLEMP-WAGO clips cable retention system
•DIMENSIONS
Models AN 2000 96x48x120 mm DIN 43700
Models AN 1500 & AN 1000 96x48x60 mm DIN 43700
•CASE MATERIAL UL-94 V0-rated polycarbonate.
•PANEL INSTALLATION without screws by means o
f
single part fastening clips
•IMPERMEABILITY of the front panel IP65 (Indoor Use).
T
o guarantee the meter's technical specifications, it is recommended
to recalibrate the meter at periodical intervals according to the
ISO9000 standards for the particular application operating criteria.
Calibration should be performed at the factory or in a qualified
laboratory.

With respect to the figures in the step-by-step instructions, the display indications may have the
following meanings:
1./ The display shows one of the available options with filled-out segments. That means
that the display shows the choice made previously. The use of allows to select from
available options.
2./ A series of black "8" also represents the display indication of a previous choice, with
the difference that it cannot be changed in the current step. If it is already the desired
parameter, you may exit from the menu by a push of ESC without making changes or,
if wanted to modify it, a push of ENTER advances the meter to the next step where
changes are allowed.
3./ A series of white "8" represents any numerical value that is programmed by using key
s
(increment digit value) and (advance to the next digit).
The programming instructions are composed by a general description and a series of step-by-step instructions to be followed
sequentially. Each menu step is represented by an illustration of the display and keyboard module with indicators (display and

3./ Input programming range.
The only configurable parameter is the input range. There are four available ranges; 15 mV, 30 mV, 60 mV or 300 mV which are
to be chosen to match the cell sensitivity (max. output in mV). The maximum voltage applicable to the instrument is 300 mV. The
built-in excitation voltage can be used to power up to 4 cells connected in parallel, with10 V excitation and up to 8 cells with5 V
excitation. Suppose 4 cells with 2 mV per Volt output that are powered from the 10 V excitation source so each one drives out 20
mV. Since they are connected in parallel, the total output voltage is 20 mV. For this configuration the instrument should be
programmed for an input range of 30 mV.
A
fter deciding the input range, we are ready to enter in the input configuration module (1 CnInP) to program this parameter.
Connect the instrument to the power supply. For a few seconds, the display will illuminate all segments, decimal points and LED'
s
as a test of their proper operation.

Magtrol AN 2000 C Instruction Manual
2./ Action modes
The figure below represents two modes of operation
obtained by programming increasing or decreasing displa
y
values for increasing input values.
Forward operation:
- When input signal
increases , the display increases .
- When input signal
decreases , the display decreases .
Reverse operation:
- When input signal
increases , the display decreases .
- When input signal decreases , the display increases .
3.2 - 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 sufficient to have good readings over the entire process
range. Other applications, 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)
Type of function Nº of scaling points
Linear function 2 points
Non-linear function Max 30 points
1./ Scaling the display.
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.

segments (7 points).
Up to 11 segments are
available.

The previously programmed INP2 value appears on the display, LED INP2 activated.
There are two methods to program input values :
Key-in method: Use to switch between "0" (positive) and "-" (negative).
Press to advance to the next digit to the right which goes in flash. Pres
s
repeatedly to increment the active digit until it takes desired value. Proceed in
the same manner with all the digits until desired value is completed on the displa
y
with sign. Press ENTER to accept this value as INP2 and go next step.
Teach method: Apply signal to the meter input. Press TEACH to view the actual
signal value present at the input connector, LED INP2 flashes. Press ENTER to accep
t
this value as INP2 and go next step.
ESC To exit from the programming mode without saving changes.
The decimal point goes in flash.
Press repeatedly the key to move it to the right until desired position. If no
decimal point is required, it must be placed to the right side of the display. Th
e
decimal point remains in the selected position in all programming phases and the run
mode.
ENTER To save the entry into the memory and go to the next programming menu
ESC To exit from the programming mode without saving changes.
Programming of the display value for the first point, activated LED DSP2. By means o
f
the and procedure, program desired DSP2 value and press ENTER . Th
e
limits of the span are -32000 and 32000 points. If the programmed value exceed
s
from these limits, the meter indicates Error, then displays 32000 with the first digit in
flash to allow reprogramming the DSP2 value within limits.
a) To save the entry into the memory and return to run mode, press ENTER ; or
b) To access to the scale linelization points, press ENTER 3 seconds.
ESC To exit from the programming mode without saving changes.
