Installation procedure
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
– Drill out wall-mount breakthroughs in the rear housing.
– Mount rear housing 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
dimensions required for transmitter service and maintenance.
– Insert two black protective covers (supplied with the M400 transmitter) over the fixing
hardware and into the space on the inside back cover, as shown in the drawing below.
This is necessary to maintain unit integrity.
– Replace the front housing to the rear housing. 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 for ordering information.

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. High voltage may
be present on the input power wires and relay wires.
A two-terminal connector on the rear panel of all M400 models is provided for power
connection. All M400 models are designed to operate from a 20–30 VDC or a 100 to 240 VAC
power source. Refer to specifications for power requirements and ratings and size power wiring
accordingly (AWG 14, wire cross-section ≤ 2.5 mm2).
The terminal block for power connections is labeled ”Power” on the rear panel of the transmitter.
One terminal is labeled – N for the Neutral wire and the other + L for the Line (or Load) wire.
The terminals are suitable for single wires and flexible leads up to 2.5 mm2 (AWG 14). 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 h symbol.

Conductivity Calibration
This feature provides the ability to perform a one-point or two-point Conductivity ”Sensor”
calibration. The procedure described below works for both types of calibrations. There
is no reason to perform a two-point calibration on a two-electrode conductivity sensor. Four
electrode sensors do require a two-point calibration.
NOTE: When performing calibration on a conductivity sensor, results will vary depending on the
methods, calibration apparatus and / or quality of reference standards used to perform the
calibration.
Enter Conductivity Sensor Calibration mode as described in section 7.1.
Choose ”standard” or ”linear” compensation mode.
Press [ENTER].

7.3
Oxygen Calibration
Dissolved Oxygen calibration is performed as either a one-point or process calibration.
7.3.1
One-Point Sensor Calibration
Before air calibration, for highest accuracy, enter the barometric pressure and relative lumidity,
as described in section 8.2.3.3.
Enter Oxygen Calibration mode as described in section 7.1.
A DO sensor calibration is always either a one point Air (Slope) or a Zero (Offset) calibration. A
one point slope calibration is done in air and a one point offset calibration is done at 0 ppb DO.
A one-point zero dissolved oxygen calibration is available but not normally recommended since
zero DO is very hard to achieve.

The calibration of an optical sensor is always a calibration of the phase of the fluorescence
signal towards the internal reference. During a one point calibration (Air or zero) only the phase
at this point is measured and the phase at the other point (Air or Zero is internally calculated.
A zero-point calibration is only recommended if high accuracy at low oxygen level (below 5%
Air) is needed.
Select 1 point followed by either Slope (Phi 100) or ZeroPt (Phi 0) as the calibration type.
Press [ENTER].
Enter the value for Point 1 including a decimal point and units. The value in the second text line
is the value being measured by the transmitter and sensor in the units selected by the user.
Press [ENTER] when this value is stable to perform the calibration.
After the calibration the slope calibration factor S (Phi 100) and the offset calibration factor Z
(Phi 0) are displayed.
After a successful calibration, the calibration values are taken over and stored in the cal history
(Adjust), only stored in the cal history (Calibrate) or aborted.
7.3.2
Two Point Sensor Calibration (only available for Optical Sensors)
A 2-points calibration is a combination of first a calibration in air (100%) where a new phase
P100 is measured and then a calibration in nitrogen (0%) where a new phase P0 is measured.
This calibration routine gives the most accurate calibration curve over the whole measuring
range.
7.3.3
Process Calibration
Enter Oxygen Calibration mode as described in section 7.1.
Select Process followed by either Slope or ZeroPt (Phi 100 or Phi 0) as the calibration type.
Press [ENTER]
Take a sample and press the [ENTER] key again to store the current measuring Value. To show
the ongoing Calibration Process, A or B (depending on the channel) is blinking in the display.
After determining the O2 Value of the Sample press the  key again to proceed with the
calibration. Enter the O2 value of the sample then press the [ENTER] key to start calibration.
After a successful calibration, the calibration values are taken over and stored in the cal history
(Adjust), only stored in the cal history (Calibrate) or aborted.
During a process calibration of an optical Sensor the phase of the fluorescence light at a point
between 5% and 100% air is measured and the phases at 100% and 0% are calculated to
determine a new calibration curve.

Process calibration at oxygen values below 5% air saturation is only available for M400 Type 3
in combination with InPro 6970 i.
The InPro 6880 i and InPro 6870 i only provide process calibration at oxygen values above 5%
air saturation.
7.4
pH Calibration
For pH sensors, the M400 transmitter features one-point, two-point (Auto or Manual mode)
or process calibration with 8 preset buffer sets or manual buffer entry. Buffer values refer to
25 °C. To calibrate the instrument with automatic buffer recognition, you need a standard pH
buffer solution that matches one of these values. (See section 8.2.3.2 for configuring modes
and selecting buffer sets.) Please select the correct buffer table before using automatic
calibration (see chapter 19).
After every successful calibration, the three following options are available:
Adjust:Calibration values are taken over and used for the measurement. Additionally,
the data’s will be stored in the calibration history.
Calibrate: Calibration values will be stored in the calibration history, but will be not used for
the measurement. The calibration values from the last valid Adjustment will be further
used for the measurement.
Abort:
Calibration values will be aborted.
Enter pH Calibration mode as described in section 7.1.

Linear compensation adjusts the reading by a factor expressed as a ”% per °C” (deviation
from 25 °C). Use only if the sample has a well-characterized linear temperature coefficient.
The factory default setting is 2.0% / °C.
8.2.3.2 pH Parameters
Select pH and press [ENTER].
Select the Drift control for calibration as Auto (drift and time criteria have to be fulfilled) or
Manual (The user can decide when a signal is stable enough to complete calibration)
followed by the relevant buffer table for the automatic buffer recognition. If the drift rate is less
than 0.4 mV over a 19 second interval then the reading is stable and the calibration is done
using the last reading. If the drift criteria is not met within 300 seconds then the calibration
times out and the message ”Calibration Unsuccessful Press Enter to Continue” is displayed.
For automatic buffer recognition during calibration, select the buffer solution set that will be
used: Mettler-9, Mettler-10, NIST Tech, NIST Std = JIS Std, HACH, CIBA, MERCK, WTW or None.
See Section 20 for buffer values. If the auto buffer feature will not be used or if the available
buffers are different from those above, select None.
STC is the solution temperature coefficient in units of pH / °C referenced to 25 °C (Default =
0.000 for most applications). For pure waters, a setting of 0.016 pH / °C should be used. For
low conductivity power plant samples near 9 pH, a setting of 0.033 pH / °C should be used.
These positive coefficients compensate for the negative temperature influence on the pH of these
samples.
IP is the isothermal point value (Default = 7.000 for most applications). For specific
compensation requirements or non standard inner buffer value, this value can be changed.
The option to enter a fixed Calibration Temperature is given. ”Fixed” allows a specific
temperature value to be entered. Selecting ”No” means the Temperature configured under 8.2.2

Press the [ENTER] key to select this Menu.
Up to 6 Setpoints can be configured on any of the measurements (a thru d). The possible
Setpoint types are Off, High, Low, Outside and Between.
An ”Outside” Setpoint will cause an alarm condition whenever the measurement goes above its
high limit or below its low limit. A ”Between” Setpoint will cause an alarm condition to occur
whenever the measurement is between its high and low limits.
Enter the desired value(s) for the Setpoint and press [ENTER]
This screen provides the option to configure a setpoint to be active on an over range condition.
Select the setpoint and ”Yes” or ”No”. Select the desired relay that will activate when the setpoint
alarm condition is reached.
Over Range
Once configured, the selected relay will be activated if a sensor over-range condition is detected
on the assigned input channel.
Delay
Enter the delay time in seconds. A time delay requires the setpoint to be exceeded continuously
for the specified length of time before activating the relay. If the condition disappears before the
delay period is over, the relay will not be activated.
Hysteresis
Enter the hysteresis as a percentage-value. A hysteresis value requires the measurement to
return within the setpoint value by a specified percentage before the relay is deactivated.
For a high setpoint, the measurement must decrease more than the indicated percentage
below the setpoint value before the relay is deactivated. With a low setpoint, the measurement
must rise at least this percentage above the setpoint value before the relay is deactivated. For
example, with a high setpoint of 100, when this value is exceeded, the measurement must fall
below 90 before the relay is deactivated.
Hold
Enter the Relay Hold Status of ”Last”, ”On” or ”Off”. This is the state the Relay will go to during a
Hold status.
State
Relay contacts are in normal state until the associated setpoint is exceeded, then the relay is
activated and the contact states change.
Select ”Inverted” to reverse the normal operating state of the relay (i.e. Normally open contacts
are in a closed state, and normally closed contacts are in an open state, until the setpoint is
exceeded). ”Inverted” relay operation is functional when power is applied to the M400
transmitter. Relay No 2 always operates inverted. All other relays can be configured.
Pressing the [ENTER] key again will bring up the Save Changes dialog. Selecting No will
discard the entered values and return to the measurement display screen, selecting Yes will

If any of these are set to Yes, an alarm signal will be initiated, the selected relay will be
activated, and an alarm message will be recorded if:
1. there is a power failure or power cycling
2. the software watchdog performs a reset
3. Rg is out of tolerance – for example, broken measuring electrode (only for pH sensors)
4. Rr is out of tolerance – for example, coated or depleted reference electrode (only for pH
sensors)
5. If the conductivity sensor is on air (for example in an empty pipe)
6. If the conductivity sensor has a short cut
7. If no sensor is connected on channel B (only for ISM sensors)
For 1 and 2 the alarm indicator will be turned off when the alarm message is cleared. It will
reappear if the power is constantly cycling or if the watchdog is repeatedly resetting the system.
Only for pH sensors
For 3 and 4 the alarm indicator will go off if the message is cleared and the sensor has been
replaced or repaired so that the Rg and Rr values are within specification. If the Rg or Rr
message is cleared and Rg or Rr is still out of tolerance then the alarm will stay on and the
message will reappear. The Rg and Rr alarm can be turned off by going into this menu and
setting Rg Diagnostics and / or Rr Diagnostics to No. The message can then be cleared and
the alarm indicator will be off even though Rg or Rr is out of tolerance.

The sensor keeps the information stored in the built in electronics and can be retrieved via a
transmitter or the ISense asset management suite.
The alarm will be reseted if the Lifetime Indicator is not 0 days anymore (e.g. after connecting a
new sensor or changes on the measurement conditions).
For amperometric Oxygen sensors, the lifetime indicator is related to the inner-body of the
sensor. After exchanging the inner-body, reset the lifetime indicator in the ISM Setup menu (menu
Configure).
For optical DO sensors the lifetime indicator is related to the OptoCap. After exchanging the
OptoCap, reset the lifetime indicator in the ISM Setup menu (menu Configure).
If the Lifetime Indicator is turned on, the value will be automatically shown in the display on line 3.

CIP characteristics: CIP Cycles will be automatically recognized by the sensor. Since CIP cycles
will vary in intensity (duration and temperature) for each application the algorithm of the counter
recognizes an increase of the measurement temperature above a certain level (70 °C for CIP). If
the temperature does not decrease below (60 °C for CIP) within the next 5 minutes after the first
temperature was reached, the counter in question will be incremented by one and also locked
for the next two hours. In the case the CIP would last longer than two hours the counter would
be incremented by one once more.
8.6.3
SIP Cycle Limit

If the Max setting is on 000, the counter functionality is turned off. The alarm will be reseted after
exchanging the sensor. For oxygen sensors, the counter can be reseted in the ISM Setup menu
(menu Configure).
SIP characteristics: SIP Cycles will be automatically recognized by the sensor. Since SIP cycles
will vary in intensity (duration and temperature) for each application the algorithm of the counter
recognizes an increase of the measurement temperature above a certain level (110 °C for SIP).
If the temperature does not decrease below (100 °C for SIP) within the next 5 minutes after the
first temperature was reached, the counter in question will be incremented by one and also
locked for the next two hours. In the case the SIP would last longer than two hours the counter
would be incremented by one once more.
8.6.4
Autoclaving Cycle Limit
The Autoclaving cycle limit counts the number of Autoclaving cycles if the limit (user defined) is
reached, an alarm can be indicated and set to a certain output relays. The following options are
possible:

PID control is proportional, integral and derivative control action that can provide smooth
regulation of a process. Before configuring the transmitter, the following process characteristics
must be identified.
Identify the control direction of the process
– Conductivity:
Dilution – direct acting where increasing measurement produces increasing control output
such as controlling the feed of low conductivity diluting water to rinse tanks, cooling towers
or boilers
Concentrating – reverse acting where increasing measurement produces decreasing control
output, such as controlling chemical feed to attain a desired concentration
– Dissolved Oxygen:
Deaeration – direct acting where increasing DO concentration produces increasing control
output such as controlling the feed of a reducing agent to remove oxygen from boiler
feedwater
Aeration – reverse acting where increasing DO concentration produces decreasing control
output, such as controlling an aerator blower speed to maintain a desired DO concentration
in fermentation or wastewater treatment
– pH / ORP:
Acid feed only – direct acting where increasing pH produces increasing control output, also
for ORP reducing reagent feed
Base feed only – reverse acting where increasing pH produces decreasing control output,
also for ORP oxidizing reagent feed
Both acid and base feed – direct and reverse acting
Identify the control output type based on the control device to be used:
Pulse Frequency – used with pulse input metering pump
Pulse Length – used with solenoid valve
Analog – used with current input device such as electric drive unit, analog input metering
pump or current-to-pneumatic (I / P) converter for pneumatic control valve
Default control settings provide linear control, which is appropriate for conductivity, dissolved
oxygen. Therefore, when configuring PID for these parameters (or simple pH control) ignore
settings of deadband and corner points in the Tuning Parameter section below. The non-linear
control settings are used for more difficult pH / ORP control situations.
If desired, identify the non-linearity of the pH / ORP process. Improved control can be obtained
if the non-linearity is accommodated with an opposing non-linearity in the controller. A titration
curve (graph of pH or ORP vs. reagent volume) made on a process sample provides the
best information. There is often a very high process gain or sensitivity near the setpoint and
decreasing gain further away from the setpoint. To counteract this, the instrument allows for
adjustable non-linear control with settings of a deadband around the setpoint, corner points

Changing the Fuse
Make sure that the mains cable is unplugged before changing the fuse. This operation should
only be carried out by personnel familiar with the transmitter and who are qualified for such
work.
If the power consumption of the M400 transmitter is too high or a manipulation leads to a
short circuit the fuse will blow. In this case remove the fuse and replace it with one specified
in Section 15.

NOTE: The pH(S) values of the individual charges of the secondary reference materials are
documented in a certificate of an accredited laboratory. This certificate is supplied with the
respective buffer materials. Only these pH(S) values shall be used as standard values for the
secondary reference buffer materials. Correspondingly, this standard does not include a table
with standard pH values for practical use. The table above only provides examples of pH(PS)
values for orientation.
