1 Introduction
1.1 Intended Use
The M400 PA multi-parameter transmitter is a single channel online process instrument with
PROFIBUS® communication capabilities for measuring various properties of fluids and gases.
The transmitter is able to measure following parameters: pH/ORP, Oxygen, Dissolved Carbon Dioxide, Conductivity and Ozone.
The M400 PA is a mixed mode transmitter able to handle analog or ISM (digital) sensors.

A large four line backlit Liquid Crystal Display conveys measuring data and setup information.
The menu structure allows the operator to modify all operational parameters by using keys on
the front panel. A menu-lockout feature, with password protection, is available to prevent the unauthorized use of the meter. Via the PROFIBUS PA interface the Analog Output Block, Discrete Input Block and Discrete Output Block can be configured for Alarm/Clean status, Hold status and
pressure compensation.
This description corresponds to the firmware release, version V1.0.0 for transmitter M400 PA.
Changes are taking place constantly, without prior notification.

2 Safety Instructions
This manual includes safety information with the following designations and formats.
2.1 Denition of Equipment and Documentation Symbols
and Designations
WARNING: POTENTIAL FOR PERSONAL INJURY.
a
CAUTION: possible instrument damage or malfunction.
a
NOTE: Important operating information.
h
On the transmitter or in this manual text indicates: Caution and/or other possible hazard includ-
a
ing risk of electric shock (refer to accompanying documents)
The following is a list of general safety instructions and warnings. Failure to adhere to these
instructions can result in damage to the equipment and/or personal injury to the operator.
– The M400 Transmitter should be installed and operated only by personnel familiar with the
transmitter and who are qualified for such work.
– The M400 Transmitter must only be operated under the specified operating conditions (see
section 16 “Specifications”).
– Repair of the M400 Transmitter must be performed by authorized, trained personnel only.
– With the exception of routine maintenance, cleaning procedures or fuse replacement, as de-
scribed in this manual, the M400 Transmitter must not be tampered with or altered in any
manner.
– METTLER TOLEDO accepts no responsibility for damage caused by unauthorized modifica-
tions to the transmitter.
– Follow all warnings, cautions, and instructions indicated on and supplied with this product.
– Install equipment as specified in this instruction manual. Follow appropriate local and na-
tional codes.
– Protective covers must be in place at all times during normal operation.
– If this equipment is used in a manner not specified by the manufacturer, the protection pro-
vided by it against hazards may be impaired.
WARNINGS:
Installation of cable connections and servicing of this product require access to shock hazard
voltage levels.
Main power wired to separate power source must be disconnected before servicing.
Switch or circuit breaker shall be in close proximity to the equipment and within easy reach of
the OPERATOR; it shall be marked as the disconnecting device for the equipment. Main power
must employ a switch or circuit breaker as the disconnecting device for the equipment.
Electrical installation must be in accordance with the National Electrical Code and/or any other
applicable national or local codes.

NOTE: PROCESS UPSETS
h
Because process and safety conditions may depend on consistent operation of this transmitter, provide appropriate means to maintain operation during sensor cleaning, replacement or sensor or instrument calibration.
2.2 Correct Disposal of the Unit
When the transmitter is finally removed from service, observe all local environmental regulations
for proper disposal.

Three options are possible for the ”Save changes” dialog: Yes & Exit (Save changes and exit to
measuring mode), ”Yes & u ” (Save changes and go back one screen) and ”No & Exit” (Don’t
save changes and exit to measuring mode). The ”Yes & u ” option is very useful if you want to
continue configuring without having to re-enter the menu.
3.2.7 Security Passwords
The M400 transmitter allows a security lock-out of various menus. If the security lock-out feature
of the transmitter has been enabled, a security password must be entered to allow access to the
menu. See section 9.3 “Set / Clear Lockout” for more information.

corner of the display. During calibration of an ISM sensor a flashing ”H” (Hold) appears. This
symbol will remain for 20 sec., after end of calibration. This symbol will remain for 20 seconds
until after the calibration or clean is completed. This symbol will also disappear when Digital In

The M400 is a single input channel transmitter, and only one sensor can be connected at the
same time.

4 Installation Instruction
4.1 Unpacking and Inspection of Equipment
Inspect the shipping container. If it is damaged, contact the shipper immediately for instructions.
Do not discard the box.
If there is no apparent damage, unpack the container. Be sure all items shown on the packing
list are present.
If items are missing, notify METTLER TOLEDO immediately.
4.1.1 Panel Cutout Dimensional Information –
1/2DIN Models
1/2DIN Model transmitters are designed with an integral rear cover for stand-alone wall mount
installation.
The unit may also be wall mounted using the integral rear cover. See installation instructions in
section 4.1.2 “Installation Procedure”.
Below are cut-out dimensions required by the 1/2DIN models when mounted within a flat panel
or on a flat enclosure door. This surface must be flat and smooth. Textured or rough surfaces are
not recommended and may limit the effectiveness of the gasket seal provided.

4.1.2 Installation Procedure
General:
– Orient the transmitter so that the cable grips face downward.
– Wiring routed through the cable grips shall be suitable for use in wet locations.
– In order provide IP66 enclosure ratings, all cable glands must be in place. Each cable gland
must be filled using a cable, or suitable Cable Gland Hole Seal.
For Wall Mount:
– Remove rear cover from front housing.
– Start by unscrewing the four screws located on the face of the transmitter, in each corner. This
allows the front cover to swing away from the rear housing.
– Remove the hinge-pin by squeezing the pin from each end. This allows the front housing to
be removed from the rear housing
– Mount rear housing to wall. Secure mounting kit to the M400 according to the supplied
instructions. Attach to wall using appropriate mounting hardware for wall surface. Be sure it
is level and securely fastened and the installation adheres to any and all clearance dimen-
sions required for transmitter service and maintenance. Orient the transmitter so that the
cable grips are facing downward.
– Replace the front housing to the rear housing. Securely tighten the rear-cover screws to
ensure that IP66/NEMA4X enclosure environmental rating is maintained. The unit is ready to
be wired.
For Pipe Mount:
– Use only manufacturer-supplied components for pipe-mounting the M400 transmitter and
install per the supplied instructions. See section 15 “Accessories and Spare Parts” for order-
ing information.

4.2 Connection of Power Supply
All connections to the transmitter are made on the rear panel of all models.
Be sure power to all wires is turned off before proceeding with the installation.
a
A two-terminal connector on the rear panel of all M400 models is provided for power connection. All M400 PA models are designed to operate in non-hazardous area from a 9 to 32VDC
power source (linear barrier: 9 to 24VDC). Refer to specifications for power requirements and
ratings and size power wiring accordingly (AWG 16 – 24, wire cross-section 0.2 mm2 to
1.5mm2).
The terminal block for power connections is labeled ”PROFIBUS PA” on the rear panel of the
transmitter. Connect the transmitter to the –PROFIBUS PA and + PROFIBUS PA terminals.
The terminals are suitable for single wires and flexible leads 0.2 mm2 to 2.5 mm2
(AWG 16 – 24). –PROFIBUS PA and +PROFIBUS PA terminals are available twice. There is no
earth ground terminal on the transmitter. For this reason the internal power wiring within the
transmitter is double insulated and the product label designates this using the d symbol.
For further information e. g. on the cable specifications, see PNO-Richtlinie 2.092 PROFIBUS PA
“User and Installation Guideline” and IEC61158-2 (MBP).
