1. Overview
The intelligent controllers are excellent components for continuous measurement and controlling of several analytical parameters. They are separated self sufficient devices, which transform, display, save and provide for further processing the
signals of the connected electrochemical sensors. The series of the MV50xx and of the MV50xxCAN in an IP65 aluminium
case and the series MV50xx-F in a plastic case for front panel mounting have a big OLED-display and an intuitive pain text
menu structure. This warranted a comfortable handling. All data will be stored in the integrated data logger. Each controller
features measurement of the corresponding parameter and the temperature, if a sensor with integrated temperature probe or a
separated temperature sensor is used, two isolated outputs for current 0(4)…20 mA or voltage 0…5 V DC, two floating limit
or alarm relay output as well as a RS232/USB interface almost for documentation and configuration purposes.
pH, redox potential (ORP) and ISE (ion selective electrodes) controllers are suitable for direct connection with combination
electrodes and separated measuring chains. Conductivity cells and membrane covered amperometric oxygen sensors for
connection with the accompanying conductivity and oxygen controller should be equipped with an integrated temperature
sensor. The controllers accept temperature sensors Pt 1000. The chlorine controller is suitable for direct connection with
sensors for measurement of disinfectants (free and total chlorine, chlorine dioxide, ozone) if these sensors feature a 2-wire
analogue current output.
2. Safety
This Operating Instructions Manual contains fundamental information that should be observed in connection with the installation, start-up, operation and maintenance of the MV50xx Measuring System. Therefore, it is absolutely vital for the user to
read this Manual prior to working with it.
User qualification
The single-parameter controller and the entire measuring system have been designed for analytical-parameter measurements.
It is assumed that the user/operator and the maintenance personnel have the proper professionals skills and experience to
know the specific properties of analytical measuring systems, master the safe handling of chemicals, for example, in the
maintenance of electrodes/sensors, and can assess any dangers and risks resulting thereof. The user must ensure that the national legislation and procedures concerning the protection of labour, the prevention of accidents and the handling of chemicals are observed.
Electrical installation work
The single-parameter controller comes ready for operation together with a power supply cable. Do not insert the plug into
sockets other than shock-proof. Do not use an extension cable without any protective conductor, as this would eliminate the
protective function. Any interruption of the protective conductor inside or outside the unit may result in the latter becoming
dangerous if another fault occurs.
Opening the unit will expose live parts. The terminal box may only be opened for the connection of sensors and other peripheral units after the mains supply has been unplugged. Such work should be done by a skilled person who is familiar with the
hazards associated therewith. Intervention into the unit will result in expiration of the warranty.
Installation and getting started
Install the device so that the conditions specified under 'Specifications' will be kept under any circumstances. The enclosures
meet the IP 65 degree of protection requirements (MV5000-F only in connection with installed transparent front cover!). A
prerequisite to this, however, is the proper installation of the enclosure cover of the terminal box and of the seals (Important:
Distinguish between the inside and outside.). Also, properly install the cables in the glands and tightly seal all cable glands not
used. For outdoor application of the MV50xx controller the use of a stand and a weather-proof roof is recommended. Do not
use any sensor and bus cables other than recommended by the manufacturer. For the sensors and accessories, the instructions
and regulations in the respective operating instructions manuals and specification sheets shall apply.
Proper usage
The controllers are intended for measuring, controlling and regulating analysis parameters. Taking into consideration the
'Specifications' paragraph in Chapter 12 operating and using the unit for this application is the proper usage. Any application
beyond this and individual modifications or extensions are improper and will lead to loss of entitlement to the warranty.
When connecting the unit with electrochemical sensors, always take into account their life and natural wear as this may result
in malfunctioning of the measuring system and the regulation or control associated therewith. The user must take suitable
measures to limit harmful effects of such malfunctioning.
General safety instructions
The controllers have been manufactured and tested in accordance with the relevant guidelines and standards for electronic
measuring equipment. They have left the factory in technically unobjectionable condition.
The proper functioning and the operational reliability of the controllers will only be guaranteed if the generally usual safety
precautions and the specific safety instructions given in this operating instructions manual and in the operating instructions
manuals of the components are observed. If it is assumed that safe operation of the unit or of its components is no longer
3/31
possible, remove the unit and its components from service and protect it against unintentional operation. Safe operation will
no longer be possible if the unit or its components
• show any transport damage.
• has/have been stored under unsuitable conditions for a longer time.
• show any apparent damages.
• does/do no longer work as described in this Operating Instructions Manual.
If in doubt, please contact your supplier.

6. MV 50xx CAN
The version MV50xxCAN provides the possibility to integrate the controllers in a bus-network with the multiparameter system KM3000. In this case the KM3000 is the master. Each controller (slave) must get a separate free
ID-number. This slave ID-number is factory-pre-adjusted or can be changed in the KM3000 (see also manual
KM3000 / para. „Change the slave-number (ID)“). It is extremely important that this number is assigned on the bus
only once. Otherwise conflicts are possible and the correct function of the whole system cannot be guaranteed.

At powering on measuring system it is very important that all MV50xxCAN already started before or powering
on simultaneously with the KM3000. Never later! Only than an error-free CAN-bus-communication is guaranteed
Please note that the configuration of the controllers and the calibration of the measuring points can be done
directly at the MV50xxCAN as well as at the KM3000. See also manual KM3000!
The desired temperature compensation must be adjusted separately in the KM3000 and in the MV50xxCAN.
Booth adjustments can be different! In the KM3000 always the measured temperature is displayed (by enabled
temperature display)! In the MV50xxCAN always the temperature used for compensation (measured or fixed) is
displayed.
The PID-controller function is not available in the version MV50xxCAN. Please use the bidirectional PIDcontrollers in the KM3000.

7. Calibration
Open with
+ password the calibration menu.
Select the calibration method.
All possible calibration methods for the respective measuring point type will be displayed.
Open your desired calibration method by selecting the corresponding menu item. The individual calibration methods
are explained in the next para. (7.1 Calibration methods).
7.1
Calibration methods
Take account of temperature compensation for all calibration methods. This means, if measured values are compensated by
temperature measurement, the associated temperature sensor must also be dipped into the calibration medium to be able to
determine the exact temperature.
7.1.1 Data „input“
Data input stands for the input of the specific ratings of the sensor connected that have, for example, been determined at the
laboratory before.
Select the corresponding calibration value whose settings you wish to change by. An input dialogue will now enable you to
change the values within corresponding limits. If you exceed these you will get an error message to prompt you to enter a
value within the fixed limits.
Select the position you would like to change by using the buttons
(+1) or
the value press
(-1). Press the
+
or
. Adjust the corresponding position with
-button to accept and save the entry. To cancel the input dialogue without saving
.
By the conductivity controller MV5020 and MV5025 the cable offset calibration value is included. That allows the entry of a
value (offset) for the compensation of the cable resistance. For this purpose, enter the cable resistance in Ohms for the 20
mS/cm and 100 mS/cm measuring ranges.
7.1.2 Setting the Temperature Offset „temp.offs.
This menu item enables you to set a temperature value offset. For this purpose open the menu item “temp.offs.”. Now, an
input dialogue will be displayed which facilitates the setting. The offset can be positive or negative.
Select the position you would like to change by using the buttons
(+1) or

Single-Point Calibration „one point“
Calibrate the measuring signal at this one point using a defined calibration solution or a known set point value, e. g. determined by a separate method or by means of a laboratory/field instrument. At first, you will be prompted to dip the sensor into
17/31
the corresponding calibration medium. After this step press
to accept the dialogue. Now, the currently measured value
will be displayed. After the measured value has attained a stable state, accept the dialogue again by pressing

For calibration of Controller MV5060 (linear characteristic for measurement of free or total chlorine) in conjunction with
corresponding chlorine measuring sensors, a single-point calibration as comparison with a known set point value determined
by a means of a photometric laboratory method is recommended. Chlorine measuring sensors feature automatic temperature
compensation integrated in the sensor. The temperature value shown during calibration is not taken into account.
7.1.4 Two-Point Calibration „two point“
Calibrate the sensor at two separate points using two different defined calibration solutions or known set point values. The
calibration points are supposed to include the measuring range or the measured values to be expected, respectively. You can

7.1.5 Automatic Calibration „automatic“
For this method of calibration, the unit automatically recognises the value of the calibration solution used, taking into account
the temperature of the calibration solutions. Automatic calibration may be single-point or two-point and is limited to the calibration solutions stored in the unit. This calibration method is applied to pH, conductivity and oxygen content measurements
only.
MV 5010 / pH-value
The automatic calibration of the pH measurement is of two-point type and requires knowledge of what buffer solutions you
wish to use. The KM 3000 multi-point controller offers the following buffer solutions for calibration:
NBS standard buffer solution as per DIN 19266:
Technical buffer solution as per DIN 19267:
Knick/Mettler-Toledo laboratory buffer solution:
Technical buffer solution:
pH value at 25 °C 1.68 / 4.01 / 6.86 / 9.18 / 12.45
pH value at 25 °C 1.09 / 3.06 / 4.65 / 6.79 / 9.23
pH value at 25 °C 2.00 / 4.01 / 7.00 / 9.21
pH value at 25 °C 2.00 / 4.01 / 6.98 / 8.95 / 11.88
You must take a choice in the first dialogue box. Again, you can choose any sequence of the buffer solutions. For further
conditions and tips, please refer to the sensor specifications.
A subsequent dialogue will prompt you to dip the sensor into the first buffer solution. Press
to confirm. Now, the
current measured value will be displayed. After the display reads a stabilised value, confirm this. Now, the same procedure as
for the first buffer solution will follow (dip sensor into buffer solution 2, wait for value stabilisation) for the second one.
As a result, you will now be given the new calibration values that will be save in the device.
MV 502x / Conductivity
The automatic calibration of the conductivity measurement is of single-point type and requires either a 0.01 molar (1.41
mS/cm at 25 °C) or a 0.1 molar (12.9 mS/cm at 25 °C) KCl solution. The temperature coefficients of these two calibration
solutions are stored in the unit. The unit will automatically recognise which calibration solution you are using (observe the
measuring range). For further conditions and tips, please refer to the sensor specifications.
At first, you will be prompted to dip the sensor into the calibration solution. Press
to accept this dialogue. Now,
an output window will appear reading the current measured value. After this value has stabilised, confirm with
As a result, you will now be given the new calibration values that will be save in the device.
.
MV 5030 / Oxygen Content
The automatic calibration of the oxygen content measurement is a single-point calibration in the ambient air. Take the sensor
out of the measuring medium and expose it to the ambient air. When doing so, make sure that neither considerable air flows
nor direct sun radiation onto the sensor will affect calibration. For further conditions and tips, please refer to the sensor speci-
fications. Now, the current measured value will be displayed. After the display reads a stabilised value, touch the
button. In this connection, temperature compensation calls for particular attention and may require a setting time of up to 30
minutes.
As a result, you will now be given the new calibration values that will be save in the device.
7.2
Calibration error
In each controller predefined ranges for the calibration values are stored. If the determined calibration value is out of the range
the message !Out of limit! appears in the calibration information CAL INFORMATION. Additional the message CAL will
be displayed in the right upper corner in the measuring display. The determined calibration value will be stored nevertheless,
so that the measuring and controlling is secured. As the case a new calibration or a replace of the sensor / sensor part (membrane head, electrolyte) is necessary.

Configuration of the fix temperature „temperature“
For calculating the analysis parameter pH und O2 a temperature compensation is always necessary. The conductivity value
can be displayed real or temperature compensated (refer to 25 °C).
For that the temperature of the measuring and of the calibration fluid must be measured or a fix temperature must be configured. If the fix temperature is activated this will be used for the temperature compensation. In this case the message Fix appears in the right upper display corner.

Configuration of the PID „controller“
For complex control tasks, a bidirectional PID controller is integrated. This controller works as analogue or pulse length
(PWM) controller by using the analogue current outputs or the relay outputs of the MV50xx.
The PID-controller function is not available in the version MV50xxCAN. Please use the bidirectional PIDcontrollers in the KM3000.
If the PID-controller is used as pulse length controller (PWM) this function has priority. Both relay outputs will
be reserved automatically for this. An additional use of the relays for 2 x limit output is not possible.
If the PID-controller is used as analogue-controller (2 x 0/4…20 mA) this function has priority. Both analogue
outputs will be reserved automatically for this. An additional use of the analogue outputs for 2 x 0/4…20 mA or
0…5 V is not possible.
For using the PID controller as analogue controller (0/4…20 mA) the actual coding (jumper) in the device must
agree.
All necessary hard- and software configuration for the desired type of the analogue outputs – current or voltage – will be
made by factory-provided.

close the device (reconnect the wires to the analogue output terminal not before the hole configuration is done!)
The PID-controller must be used as quasi-continuous controller. For simple control tasks, the integrated controller can be set
as single proportional controller. You can also set a controller with a differential and/or integral portion. If you define an
integral action time of 0 the controller will be used without an integral portion. The same applies to differential time.
Processes for controlling the pH value are non-linear. The transmission constant of the system in the set point value range is
often higher by some orders of magnitude as at the limits of the control range. The use of the controller with fixed setting
values will result either in an instability of the control loop near the set point value or in extremely long settling times (for
batch processes), or in high deviations (for continuous processes with greater disturbance variations), respectively. The controller integrated in the MV50xx can be matched to such distinctive features of the process. The general static characteristic
curve of the controller is shown below. It facilitates the realisation of different transmission responses for certain parts of the
control range.

Configuration of a pulse length controller (PWM)
The pulse length controller is firmly linked with the two relay outputs (refer to the characteristic curve). Within the cycle time,
a switching pulse that intervenes into the control process is calculated, depending on the deviation from the set point. The
control value is re-calculated at the beginning of each cycle time. The minimum time - the shortest period of a control action can be set for adaptation to different active modules. It is to prevent switching processes that are too fast for the active module. If it is undercut, and if the controlled quantity is out of the dead band, the active module will be triggered with the minimum time. If the turn-off time is shorter than the minimum time the relay will continuously stay turned on.

The analogue controller is firmly linked with the two analogue outputs (refer to the static characteristic curve). After the sampling rate has elapsed, the controller is re-calculated and the resulting current provided at the output. This current will be kept
constant for the period of the sampling rate.
If the PID-controller is configured as analogue-controller the analogue outputs will be configured automatically
