1 • PRELIMINARY INSTRUCTIONS
This section contains information and warnings
of a general nature which should be read befo-
re proceeding with controller installation,
configuration and use.
General Description
The instrument is appropriate for acquisition of signals
with high variation speed. It has two main analog inputs
for many applications, including differential measure-
ments. The inputs are configurable from the keyboard
and accept standard linear signals (and custom lineari-
zed signals), as well as signals from pressure probes,
load cells, potentiometers, TC, RTD.
They offer an exclusive combination of performance,
reliability, and applicative flexibility. In particular, this
new line of Gefran indicators/alarm units is the ideal
solution for sectors demanding high performance and
continuity of service, with:
• pressure measurements and setpoints on extrusion
lines and injection presses for plastics
• pressure measurements and setpoints
(absolute or differential)
• position measurements and setpoints
• variable setpoints in fast processes and automations,
with retransmission
The instrument also has 2 digital inputs for reset, calibra-
tion, and hold functions.
The outputs (up to 4) are relay or logic, and are configu-
rable.
An MD8 expansion is available as an alternative to out-
puts 3 and 4 for 8 additional setpoint outputs.
An optional, high-resolution, optically isolated analog out-
put is available for analog retransmission, process varia-
ble value, peak value, setpoint, differential value.

2 • INSTALLATION AND CONNECTION
This section contains the instructions necessary
for correct installation of the instrument 2400
into the machine control panel or the host
system and for correct connection of the control-
ler power supply, inputs, outputs and interfaces.
Before proceeding with installation read the
following warnings carefully!
Remember that lack of observation of these
warnings could lead to problems of electrical
safety and electromagnetic compatibility, as
well as invalidating the warranty.
Electrical power supply
• the instrument is NOT equipped with an On/Off switch:
the user must provide a two-phase disconnecting
switch that conforms to the required safety standards
(CE marking), to cut off the power supply upstream of
the instrument.
The switch must be located in the immediate vicinity of
the instrument and must be within easy reach of the
operator.
One switch may control more than one controller.
• if the instrument is connected to NOT isolated electrical
equipment (e.g. thermocouples), the earth connection
must be made with a specific conductor to prevent the
connection itself from coming directly through the
machine structure.
• if the instrument is used in applications with risk of
damage to persons, machinery or materials, it is
essential to connect it up to auxiliary alarm
equipment. It is advisable to make sure that alarm
signals are also triggered during normal operation.
The instrument must NOT be installed in flammable or
explosive environments; it may be connected to
equipment operating in such atmospheres only by
means of appropriate and adequate types of
interface, conforming to the applicable safety
standards.
Notes Concerning Electrical Safety and
Electromagnetic Compatibility:
CE MARKING: EMC Conformity (electromagnetic
compatibility)
in accordance with EEC Directive 89/336/CEE and follo-
wing modifications.
The instrument series 2400 are mainly designed to ope-
rate in industrial environments, installed on the switch-
boards or control panels of productive process machi-
nes or plants.
As regards electromagnetic compatibility, the strictest
generic standards have been adopted, as indicated in
the table below.

Advice for Correct Installation for EMC
Instrument power supply
• The power supply to the electronic equipment on the
switchboards must always come directly from an
isolation device with a fuse for the instrument part.
• The electronic instruments and electromechanical
power devices such as relays, contactors, solenoid
valves, etc., must always be powered by separate
lines.
• When the electronic instrument power supply is
strongly disturbed by the commutation of transistor or
power units or motors, an isolation transformer
should be used for the controllers only, earthing the
screen.
• It is essential that the plant has a good earth
connection:
- the voltage between neutral and earth must not be >1V
- the Ohmic resistance must be < 6Ω;
• If the mains voltage fluctuates strongly, use a voltage
stabilizer.
• In the proximity of high frequency generators or arc
welders, use adequate mains filters.
• The power supply lines must be separate from the
instrument input and output ones.
Inputs and outputs connection
• The externally connected circuits must be doubly
isolated.
• To connect the analogue inputs and analog outputs
the following is necessary:
- physically separate the input cables from those of the
power supply, the outputs and the power connections.
- use woven and screened cables, with the screen
earthed in one point only.
• To connect the relay outputs
(contactors, solenoid valves, motors, fans, etc.), fit
RC groups (resistance and condensers in series) in
parallel to the inductive loads that operate in
Alternating Current.
(Note: all the condensers must conform to VDE
(class X2) standards and withstand a voltage of at
least 220V AC. The resistances must be at least 2W).
• Fit a 1N4007 diode in parallel with the coil of the
inductive loads that operate in Direct Current.
GEFRAN S.p.A. declines all responsibility for
any damage to persons or property caused
by tampering, neglect, improper use or any
use which does not conform to the characte-
ristics of the controller and to the indica-
tions given in these Instructions for Use.
