Meter M40-P

Panel meter 96x48mm size for process signals

Panel meter for process signals in mA and Vdc, active and
passive, monopolar and bipolar, from 2 or 3 wire transducers.
Provides +15V (max. 40mA) excitation voltage to power-up
the transducer when needed. Scalable reading. 10 segment
linearization.

Instrument with 96x48mm standard DIN size. Resolution 4
digits plus negative sign (“-9999”) or 5 digits with negative
sign with last digit xed to zero (“99990”, with menu function
“Right Zero”).

Management for up to 4 alarms with 1 or 2 setpoints each,
with hysteresis and delays. Provides memory for maximum

and minimum, left zeros, display on selectable steps, xed
digits, recursive display lter, password, brightness control,

“measure” function (visualizes input signal without scaling),
offset and signal high autocorrection (assigns the actual
signal to the low or high reading), “peak&hold” function and
password.

Power options with universal AC and DC ranges, and space
for 2* additional control and/or signal retransmission modules
(*soon 3 modules).

For measurements in CAT-II and for environments with de­gree of pollution 1 and 2 without condensation. Standard IP54
front protection, with optional upgrade to IP65 protection.

Connections via plug-in screw terminals and conguration

via three front push-buttons. For application on industrial
environments.

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.

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

Instrument protected with double isolation. No earth connection
required.

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.

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

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.
