BASIC RECOMMENDATIONS
This Manual is addressed to the instrumentist responsible of programming and configuration and
start-up of these instruments.
NOTE: These instruments are provided, from factory, with protection level allowing the access
to the display parameters. The access to the submenus is protected with Passwords, to avoid
any misuse which may alter the configuration already stored in memory.
These INSTRUCTION MANUALS are continuously improved
by our publication’s department, generating updated
versions in PDF format available on our website:

CONSIDERATIONS ABOUT THESE INSTRUCTIONS
●
The instruments of the HS-7000 Series are fully programmable processors, so that, all the
function provided in its Function Blocks can be enabled or disabled by key pad or by software,
to fit the application requirements. The Function Blocks of the HS-7000 can be linked to each
other, allowing infinity of control structures to fit almost every application.
●
This feature makes the menu in the HS-7000 Series to be non-linear one, so that it is
impossible to explain how it operates following the pre-established structure of menu.
●
Moreover, these functions represented as symbols on the display, can be assigned to any
of the three loops or to any Password level available in the instrument, so that it can be
located, in the menu, in different positions according to the programmer and the application’s
requirements.
●
This is why the display of the HS-7000 is different from other displays, since it can display
between 6 and 15 different values by multiplexing the screens on the display. These screens
are identified and presented as Meauring or Control Loops L1, L2 and L3, to which, can be
assigned any measured or calculated signal. Every loop can be selected by using the key
from any position of the MAIN MENU.
●
Thus, in the HS-7000, one display may shows the one input signal, the other one the Total
of a flow measurement and the third one may displays a hold value, or one setpoint, or the
control output value, etc.
●
Those instruments, because of its versatility, performances, accuracy and fast response are
considered as high range instruments of its segment.
The operation instructions are organized in different sections to ease the operation of
Parameterization, Configuration and Specific Applications, as follows:

realized by the own
fittings of enclosure or
by the enclosed
brakets.
The panel wall should
be 0,8 to 2 mm (0.03 a
0.08 in) thick.
INSTALLATION
MOUNTING PRECAUTIONS
Avoid direct sources of light and heat. Locate the instruments away from corrosive vapours,
dripping, moisture, temperature over 50 °C, vibration, etc. Keep away of electromagnetic
radiation, radio frequency, microwave and high voltage sources, etc.
It is recommended to follow the GENERAL PRECAUTIONS indicatd in the instruction shhet

WIRING
VERY IMPORTANT: These instruments are CE Marked, however, to avoid external
interferences, it is recommended to following wiring precautions.
WIRING PRECAUTIONS
Before connecting the main power or the inputs and outputs, check the data listed on the
manufacturer’s sticker carefully.
An improper installation could expose the device to transients and mains noise that may cause
frequent interruptions in display power with momentary display of [Erro] messages.
To avoid it, these instruments are provided with a safety element (Watchdog) that restores the
normal operation immediately after perturbances.
Please contact your distributor for further information.
CONNECTION TO MAIN POWER
●
The power supply for the instruments must be taken as directly as possible from the
general mains using a star connection (do not
supply several devices at the same power line).
●
Do not power relay coils, contactors, etc. with the
line used to power the instruments.
●
In the case of a very noisy power supply (due to
power units, i.e. thyristors), instrumentation should
be powered using an insulation transformer with a
grounded shield.
ANALOG INPUTS
●
Physically separate the signal lines (mV, Pt 100, 4-20 mA) along the entire length of the
power or relay command lines, contactors, servomotors, actuators, etc. (using separate,
independent racks or conduits).
●
Shielded, twisted pair wire must be used for extra-long signal cables.
IMPORTANT: The shield must be connected to Ground at a single point on the side
where the signal is received, i.e., at a grounding terminal close to the instrument (in star
grounding).
●
Thermocouple input:
Use an extension or compensation wire UNTIL THE DEVICE TERMINALS, observing the
polarity when connecting.
●
Pt 100 input:
Use 3-wire cable to compensate the effects of copper wire resistance (1.5-mm
2
cross-section or AWG15 gauge).
●
mV input:
Use 1.5-mm
2
copper-copper wire or AWG15 gauge. Ensure correct polarity.
Star
Serial
connection
YES NO
Mains

13
●
mA input:
Use 1.5-mm
2
copper-copper wire or AWG15 gauge. Ensure
correct polarity, and do not forget the 3.74 Ωparallel shunt
(included) in the terminals.
Relay output (CONTACTS)
●
To enlarge the life of the relay contacts, RC circuits (Resistance and Capacitaor in series)
are installed in parallel to the relay contacts.
ATTENTION: This may cause false effect of continuity between the output terminals
which do not mean that the relays are not operating properly.
●
Besides the RC circuits, in some cases, additional anti-noise circuits may be necessarily
wired at the terminals when strong inductive loads are operated, such as Auxilairy relays,
servomotors, contactors, etc.
4-20 mA output
●
Use of shielded twisted pair is recommended, with the shield
connected to Ground as explained above.
GROUND
●
If available, connect the shield of cables in star configuration to a single point of the
equipment (metal frame ground), using a conductor with the same cross-section as the
power supply or communication wires.
Shield Grounding
Communication lines grounding. Connect only
one end of the shield. Do not coonect additional
shields between the instruments.
