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.

Magtrol AN 2000 C Instruction Manual
The AN 2000 C model incorporates new technical and
functional characteristics including ±32000 coun
t
display, signal linearization of up to 30 points and use
r
programmable remote logic functions that provides an
extraordinary flexibility to adapt to a wide range o
f
indication and control needs.
The model AN 2000 C of the AN series is a digital indicato
r
designed to measure forces (weight, load, torque, pressure ...)
that admits connection of several bridge such as load-cells with
small signal levels up to ±300 mV.
It provides four selectable input ranges (±15 mV, ±30 mV,
±60 mV or ±300 mV) and two excitation voltages (5 V or 10
V
) that allow to accommodate different cell types and inpu
t
sensitivities. Two programming modes permit scaling the
meter to fit the desired units for specific applications.
The meter has two input filtering methods with selectable
levels and selectable resolution to help stabilizing the displa
y
according to the process type.
The basic instruments is a soldered assembly composed of the
MAIN BOARD, the DISPLAY and the power FILTERING circuit,
plus the A/D converter card and the INPUT card that are
located in their corresponding plug-in connectors (see figure in
page 4).
Standard features of the basic instrument include the reading
of the input variable, max and min detection, remote hold
operation, tare function and reset and a full complement o
f
programmable logic functions.
In addition, a variety of plug-in output cards can be installed a
t
any time to meet further system requirements:

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 bloc
k
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 allo
w
proper fastening for cable sections of <0.5 mm².

INSTALLATION
T
o meet the requirements of the directive EN61010-1, where the uni
t
is permanently connected to the mains supply it is obligatory to install
a circuit breaking device easily reachable by 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 ²
If not installed and used according to these instructions,
protection against hazards may be impaired.
