The sensors are connected to the converter via the M12 socket 5 at the lower side of the
converter housing using 10 m / 33 ft cables which are attached to the sensor. If the standard
cable length is not sufficient several cables may be connected in series. The maximum length is
100 m / 328 ft.
18
In the event that more than one sensor is connected to the same converter, then the junction box
is needed. Furthermore, for the connection of 3...4 sensors an extra 4...20 mA module or a
Profibus DP module must be installed in the converter to transfer the measuring results to a
SCADA or DCS system.

OPTISENS MAC 080
Digital inputs
The 3 digital inputs are used to select calibration curves for consistency or suspended solids
sensors from a remote location. They are activated by applying +24 VDC and have a common
ground. We suggest the use of a 4-lead AWG20 (0.5 mm
4...20 mA outputs
As a standard, there are 2 analog 4...20 mA outputs to transfer the measuring results from the
converter to a SCADA, DCS or other type of system. The use of the two outputs is configured in
the sensor menu, and the converter will prevent two sensors from using the same output. We
suggest using a shielded twisted pair AWG20 (0.5 mm
another system. If both outputs are connected to the same system a double twisted pair cable
may be used. Make sure the shield is properly grounded according to EMC practice.
Optional, the converter can be extended with 2 additional analog 4...20 mA outputs via an
expansion module.

The two relay outputs may be configured to be used for alarm or cleaning. The cable type
required depend on the use and selected voltage. Make sure that the maximum ratings of the
outputs are not exceeded. Maximum rating per relay is 250 VAC / 12 A.
A connection diagram for the relays is attached on the inner side of the front door of the
converter housing.
Power
The converter is connected to power using a 3-lead cable approved for the rated current and
voltage. We recommend that power has to be connected with an external on/off switch.

4.3.1 Analog outputs
The two analog outputs of the converter are default active, sourcing 4...20 mA into a load of
maximum 450 Ω. They are galvanic isolated from the rest of the system, but the two channels
use a common ground.
Channel 2 can be jumpered to be passive, and fully isolated sink 4...20 mA from an external
supply of max. 24 VDC, by changing JP1 and JP7.

4.3.2 Digital inputs
The three digital inputs are using the converter’s internal 24 VDC. To use an external 24 VDC
source, galvanic isolated from the rest of the system (e.g. from a DCS or control system), the
inputs need to be jumpered. These inputs can be used for selecting calibration for sensors
having more than one calibration curve by setting up the sensor to use an external calibration.
To connect a sensor using a multiple point calibration (setup external calibration) the digital
outputs are used to select calibration of the sensor.
No active input will result in calibration curve "A". If input 1 is activated calibration curve "B" will
be used, if input 2 is activated calibration curve "C" will be used, and finally if input 3 is activated
calibration curve "D" will be used. The higher the number of the input the more dominant it is, in
other words if input 3 is active calibration curve "D" will be used regardless of the state of the
other inputs.

CAUTION!
Do not overpower the relay contacts! Max. rating per relay is 250 VAC, 12 A)
Observe the following points
• The relays are a normally open contact only. For driving solenoid vales and other devices use
external power sources.
• During setup, please verify that the relay is not already being used for another function like
flush cleaning.
• Several solenoid valves may be connected to the same terminal block. However, the power
rating of the relay output must not be exceeded.

All sensors are equipped with integrated spray cleaning. The cleaning function is controlled by
the converter relays. A solenoid valve is connected to relay contact 1 or 2, which must be
configured in the sensor menu.
In order not to interfere with the measurement, the output of the sensor is frozen during the
cleaning and for the configured I-time after the cleaning. Additional freeze time can be
configured if required.

4 ELECTRICAL CONNECTIONS
If more than one sensor shall be cleaned using the same relay, one of them is configured as
master, with all parameters set, to use the relay. The others are configured to clean as slaves
along with the selected relay. The output of a slave is frozen during the cleaning and additionally
its own I-time and its own additional freeze time if used. Other cleaning parameters cannot be
configured for a slave, the master’s configuration is used.
INFORMATION!
If relay 1 is set for alarm then relay 2 can be used for flushing and vice versa.
The following procedures are to be performed
• Connect the solenoid valve to relay contact 1 or 2 (relay 1 - terminals 11/12 or relay 2 -
terminals 13/14; for detailed information refer to
• Configure the relay for cleaning in the sensor menu under "Cleaning/Relay" (refer to the
sensor manual).
• Check that flushing water/air pressure does not exceed 8 bar / 116 psi rating of solenoid
valves. Refer to the sensor manual for maximum flush pressure for the sensor.
Automatic cleaning is not started when a menu is open. This is to avoid flushing during
maintenance and calibration.

5.1 Start-up
Start-up of the device begins when power is supplied. While a self-test is being performed, it
may take up to 30 seconds for the sensor to initialize and be identified. Changes to the settings
can not be made until the converter has recognized the sensor. When recognized, the sensor will
appear in the display mode.
If the self-test indicates that the internal clock has been without electric power for a period of
time, the unit goes to a menu for setting date and time. After this setting is complete, the display
mode shows the sensors in the order in which they were tagged or the slot number.
5.2 Connect sensors
When the converter detects a new sensor an identification process is started, indicated by a
rotating line between the header and the time on the first line of the display. Once the sensor is
identified, the converter asks how it shall be used. Default choice is to connect the sensor to an
empty slot from a list of free slots. If no slot is free, a message saying so will be displayed. Slots
with no sensor currently connected can be freed in the converter menu. If a sensor is added to
slot 1 or 2, the converter will ask if the corresponding 4...20 mA output shall be used (unless it is
already used by another sensor). The use of an output can be changed in the sensor setting
menu.
START-UP 5
If an identical sensor has been connected, but is currently not, the slot of this sensor can be
reused. The new sensor inherits most of the configuration and calibration of the old sensor. This
function is intended to quickly get up and running when a sensor is replaced. The inherited
calibration will not be perfect since it’s done for another sensor, but it will be closer than the
factory default. Some sensor types can not reuse slots.

6.1 Operational interface
6.1.1 Main display
The layout of the main display varies depending on the number of sensors connected. The
converter can handle up to 4 sensors. The slots in the menu are numbered top down from 1 to 4.
The first line of the display always shows the internal clock and the temperature of the active
sensor. Slots without a sensor connected are shown with the text "empty slot". Connected
sensors are shown with their name, the measured value, the unit and a bar indicating
percentage of full scale. If the contact with a sensor is lost, the text "No transmitter" is displayed
in the slot where the sensor is configured. At the bottom of the screen, the min. and max. values
for selected sensor are displayed. An arrow to the left of the sensor name indicates the active
sensor.

• Use the buttons ↑ or ↓ to select a sensor in the main display.
• An empty slot cannot be chosen for display.
• If communication with the sensor is lost the slot may still be chosen for display. The arrow
returns to the first active sensor after five seconds.
• The sensor name (max. 10 characters) can be changed in the sensor menu, default is the type
of sensor.
6.1.2 Sensor display
Many (not all) sensors have one or more info displays showing extra information about the

6.1.3 Menus
There are different menus to configure the converter and the sensors. One set of menus is for
settings referring to the converter and another set of menus is for settings referring to each type
of sensor.
INFORMATION!
This manual only describes the menus used to configure the converter. For information
regarding the different sensor menus, please refer to the sensor manual.
When a menu is open the automatic cleaning is inhibited. The values of the two analog outputs
are frozen in order to avoid unnecessary alarms in the control system when parameters are
changed, and during calibration. This functionality can also be used if a sensor shall be
temporary removed, e.g. to be inspected or cleaned. Just remember that open menus will time
out if not used for 8 minutes.
Time out for menus
Menus that are inactive for more than 8 minutes are automatically closed and the converter
returns to the main menu. A menu is not considered to be inactive if a value is being edited, a
dialogue box is open, or a function, e.g. calibration, is carried out. The backlight of the display is
switched off at the same time, it is switched back on by pressing any button.

6.1.6 Changing values in the menus
A highlighted area in the converter means that you can use the ↑ or ↓ keys to change the
selection. However, an exception is when values or numbers are displayed one figure at a time.
In this case, the arrow keys are used to change the value and ^ is used to advance to the next
digit. Simultaneously pressing ↓ and ^ steps back one digit.
When changing options, the highlighted option "Settings" indicates that ↑ and ↓ can be used to
change between options. When the shaded area is over a number, then the arrow keys will
increase or decrease the value.
Occasionally, a list indicator (R) will appear in a dialog box. This indicates that the user can use
the arrows to select between the different functions that are available.
When a value can not be displayed, which might be due to the fact that it is to large, negative or
an error has occurred in a calculation, stars are shown instead of a number, e.g. *****.*
(number of stars is depending on value and unit settings). If it is possible to edit the parameter it
can be set to zero by pressing ^ a number of times. All selected changes are implemented
immediately and measuring is continued.
OPERATION 6
6.1.7 Dialogs
The converter sometimes shows a small dialog box containing a message. Sometimes at the
bottom of the dialog box there is a message that says, "Enter". This indicates that the dialog will
be confirmed and consequently disappears when the ^ key is pressed. If several dialogs are
stacked, the one at the top will be confirmed first.
6.1.8 Sensor menu
The sensor menu is accessed by first selecting the sensor, then pressing ^ for five seconds. See
the sensor manual for more information.

When a measured value goes above a high alarm limit or goes below a low alarm limit an alarm
is triggered, and an alarm window is displayed on the converter telling what sensor and reason
caused the alarm. If a second alarm occurs a second line is added in the window. When an alarm
is active the panel LED will change from green to red, measurement will continue uninterrupted.
An alarm is acknowledged by pressing the ^ button. If there is more than one alarm, they are
acknowledged one at a time in chronological order.
OPTISENS MAC 080
Alarm is issued if the following is fulfilled
• An alarm limit (high, low or both) other than zero is set in the sensor "Scale"/"Alarm" menu.
• The sensor menu for this sensor is not active (alarms are blocked while the menu is open).
• The measured value has been OK since it passed the alarm limits last time.
It is not needed for an alarm relay to be configured to activate the internal alarm handling.
Alarm type
Alarms can be configured under "Settings" / "Alarm type" to automatically disappear when the
signal level gets back within the limits or to stay on until it is acknowledged with the ^ button.
The level type is intended to be used to control an activity, e.g. a pump or dosing valve while the
confirmed type is intended to inform the user about the alarm condition.
Alarm relays
The same relay is always used for high and low alarms from a sensor. One alarm relay can be
used for one or more sensors. Once an alarm relay is triggered, it is not released until the last
active alarm connected to this relay is acknowledged or the measured value returns to normal,
depending on the selected alarm type.

8 TECHNICAL DATA
8.1 Measuring principle
The converter is based on a 16-bit microprocessor. The internal software uses a real-time
operating system, allowing multiple tasks to be carried out in "parallel". One process takes care
of the display and the dialogs, one process is dedicated to handle each attached sensor, and one
task is taking care of all the housekeeping.
After power up, the software will initialize the functionality and data structures, reading
information from a non-volatile memory. A welcome message is displayed for about ten
seconds, showing the software version and serial number of the converter. The unit will then
start looking for sensors it already knows, and if found initialize them to start measuring. Twice
a minute the unit looks for unknown sensors. If one is found, the converter will find out the type
and serial number and open up a dialog box to let the operator select what slot to use for the new
sensor.

9.2.3 Mounting the expansion module
If the converter is ordered with Profibus option included, the Profibus DP expansion module is
already pre-mounted inside the converter. If this option is ordered separately, the module shall
be mounted inside the converter following the instructions below.
DANGER!
All work on the electrical connections may only be carried out with the power disconnected. Take
note of the voltage data on the nameplate!
CAUTION!
Connect yourself and the converter chassis to protective ground before opening the antistatic
package of the module!
This will avoid static discharges that can damage the module or the box.
How to get started:
• Make sure the converter to be used is switched off.
• Open the front and locate the bus module connector.
• Connect yourself and the converter chassis to protective ground before opening the antistatic
package of the module.
• Mount the module into the box, be careful to fit all 34 pins into the socket.
• Fasten the three M2.5x5 screws.
• Set the rotary switches to the desired node address, or to "0 0" if you want to configure the
address in the converter menu "Settings / Profibus".
• Set the bus termination switch in position "On" if this is the last unit on the bus, else set it to
"Off".
• Connect the Profibus network to the screw terminals according to the table below.
• Switch on the power to the converter box and check that the green led on the module starts
flashing.
• If you have not set the address switches on the module you must set the node address in the
converter menu "Settings / Profibus", exit the menu and then switch the power off at least
10 seconds before it is switched on again.
• Check in the converter menu "System / Profibus" that the module is found and initiated.
• Configure the master system (PC, PLC or DCS) to communicate with the converter at the
selected node address using the data structure described in the following chapter.
• When the communication starts working the red LEDs in the lower right corner of the module
will go dark, and the green LED will light up.
• In the converter menu "System / Profibus", "Online" will shift to "Yes". Now the Profibus
communication should be working.

9.2.4 Baudrate
The baudrate on a Profibus DP network is set during configuration of the master and only one
baudrate is possible in a Profibus DP installation. The Profibus DP module has an auto baudrate
detection function and the user does not have to configure the baudrate on the module.
Baudrates supported by the Profibus DP module are:
• 9.6 kbit/s
• 19.2 kbit/s
• 93.75 kbit/s
• 187.5 kbit/s
• 500 kbit/s
• 1.5 Mbit/s

9.2.5 Termination of DP network
OPTISENS MAC 080
The end nodes in a Profibus DP network has to be terminated to avoid reflections on the bus line.
The Profibus DP module is equipped with a termination switch to accomplish this in an easy way.
If the module is used as the first or last module in a network the termination switch has to be in
ON position. Otherwise the switch has to be in OFF position.
INFORMATION!
If an external termination connector is used the switch must be in OFF position.
Termination switch ON Bus termination enabled. If the module is the last or first module, the bus

9.2.6 Node address
The Profibus DP node address has to be set in the field. This can be done in two ways:
• Two rotary switches on module can be set for 1...99.
• Setting the switches to 00 tells the module to use the address configured in the converter
menu. It can be set from 1...125. To set up address you go into the converter menu by
pressing ENTER and ↑ for 5 seconds together. Then go down to "Setup" and press ENTER.
Scroll down to "EXP. Module" and press ENTER. Screen will say "NODE ADDRESS 002".
Change address between 2...125 and then press ENTER to exit (The reason to start with no
002 is that the main control system normally is addressed as 001).
Do not forget to terminate box if this is the first or last item in loop as shown above.
INFORMATION!
The node address is not changed just by adjusting the settings. The converter must be turned off
for 10 seconds and then powered up for address to be recognized.
9.2.7 GSD file
APPENDIX 9
Each device on a Profibus DP network is associated with a GSD file, containing all necessary
information about the device. This file is used by the network configuration program during
configuration of the network. The latest version of GSD file can be received by contacting us.
