Meter S40-R

Panel meter 72x36mm for ratiometric and potentiometer signals

Panel meter for ratiometric and potentiometer signals, from 3
wire transducers. The meter provides +5V (max. 35mA) and
a 0V signal, and receives from the transducer a signal be­tween 0 and 5V. Scalable reading. 10 segment linearization

Reduced size 72x36mm DIN standard instrument, maintains
standard 14mm digit height, with full 4 digit resolution plus
additional negative sign.

Management for up to 2 alarms with 1 or 2 setpoints each,
with hysteresis and delays. Functions available include seg­ment linearization, memory of maximum and minimum, left

zeros, steps on display, xed digits, recursive display lter,

Precautions on installation

Risk of electrical shock. Instrument terminals can be connected
to dangerous voltage.

Instrument protected with double isolation. No earth connection
required.

Instrument is in conformity with CE rules and regulations. See
“CE Declaration of Conformity” further in this document.

This instrument has been designed and veried according to the 61010-1

CE security regulation, and is designed for applications on industrial environ­ments. See the “CE Declaration of Conformity” further in this document for
information on the category of measure and the degree of pollution levels
that apply.

Installation of this instrument must be performed by qualied personnel

only. This manual contains the appropriate information for the installation.

Using the instrument in ways not specied by the manufacturer may lead
to a reduction on the specied protection level. Disconnect the instrument

from power before starting any maintenance and / or installation action.

FEMA ELECTRÓNICA - Page 2

The instrument does not have a general switch and will start operation as
soon as power is connected. The instrument does not have protection fuse,
the fuse must be added during installation.

The instrument is designed to be panel mounted. An appropriate ventilation
of the instrument must be assured. Do not expose the instrument to excess
of humidity. Maintain clean by using a humid rag and do NOT use abrasive
products such as alcohols, solvents, etc.

General recommendations for electrical installations apply, and for proper
functionality we recommend : if possible, install the instrument far from
electrical noise or magnetic eld generators such as power relays, electri­cal motors, speed variators, ... If possible, do not install along the same
conduits power cables (power, motor controllers, electrovalves, ...) together
with signal and/or control cables.

Before proceeding to the power connection, verify that the voltage level
available matches the power levels indicated in the label on the instrument.

In case of re, disconnect the instrument from the power line, re alarm
according to local rules, disconnect the air conditioning, attack re with

carbonic snow, never with water.

Earth connection - Although a terminal is offered for earth connection, the
connection is optional. The instrument does not need this connection for
correct functioning nor for compliance with the security regulations.

Fuse - To comply with security regulation 61010-1, add to the power line
a protection fuse acting as disconnection element, easily accessible to the

operator and identied as a protection device.

Power “H” fuse 250mA time-lag

Potentiometers Pots from 200 Ohm up to 5 MOhm

The instrument provides two ranges for potentiometer mea­surement. In Pot<5K measurement range, the measure is

direct (no additional conguration is needed). In Pot<5M it

is needed to introduce the nominal value of the potentiom­eter to reach the assigned accuracy. This value is requested
when the Pot<5M is selected.
