1.2 Intended use
The OPTISYS SLM 2100 sludge level meter is primarily designed for use in water and waste
water treatment plants. There it determines the sedimentation profile in clarifiers and sludge
thickeners and detects sludge blanket or fluff level. For this it measures the suspended solids
concentration and height of the sensor above ground as the sensor is lowered into the basin or
tank.
However, the design of the OPTISYS SLM 2100 makes it possible to use it in other applications
where reliable monitoring of interface or stratification in suspensions is necessary.
SAFETY INSTRUCTIONS 1
The OPTISYS SLM 2100 shall not be used in hazardous areas, which e.g. require Ex approvals. It
could ignite gases. Additionally, due to the sensors material, the meter shall not be used in
applications with a high concentration of salt (e.g. seawater). The device has been constructed
for indoor and outdoor use below the maximum altitude of 2000 m / 6562 ft.
By observing the operation instructions, national standards, safety requirements and accident
prevention regulations the residual risk is reduced to an acceptable level.

2 DEVICE DESCRIPTION
Cable drum assembly and heater unit
The cable drum helps to move the sensor up and down in the basin. It is mounted directly on the
motor shaft of a synchronous motor, hidden behind the drum mounting plate. The cable drum
always moves with a very constant speed. Since the diameter of the cable roll in the drum varies,
the speed of the sensor varies. That is why the sensor moves slower during the end of the
sampling.
The heater unit is located behind the drum mounting plate. In conjunction with the fan it
maintains a stable temperature inside the enclosure of the meter.
Guide roller
The guide roller helps to keep the cable in place during the measuring process.
Sensor
The sensor contains a near-infrared light source and a receiver. Both are positioned in such a
way that the emitted near-infrared light has to pass through the liquid before reaching the
receiver.
Pickup board & axle board
The pickup board is mounted on a spring loaded lever arm and transfers power and
communication signals to the cable drum.
OPTISYS SLM 2100
The axle board on the cable drum is powered contactless ("inductively") from the pickup board. It
communicates with the main electronics unit via the pickup board and with the sensor via an
optical interface.
Cable feedthroughs
The four M20 cable feedthroughs are for the connection of power, signal and control cables.
Safety switch
The safety switch located on the top left corner of the cable drum compartment is a protective
device, which de-energizes the motor when the front door is opened in order to avoid danger due
to moving parts inside the meter.
Cleaning unit (optional)
The cleaning unit, mounted under the device, consist of a valve and a spraying system to keep
the sensor and cable free of deposits ensuring low maintenance efforts of OPTISYS SLM 2100.

4.10 Description and properties of the relays
DANGER!
Never install or operate the device in potentially explosive areas, it might cause an explosion that
can result in fatal injuries.
The two relays can be either configured as limit switch or as status output.
In status output mode:
If an error of the selected class occurs the relays remains active, until the error is cleared by the
user or the device is leaving the error state automatically.
In limit switch mode:
When the relay is configured as limit switch the limit parameter used is the sensor position
(height / depth). The relays can work as limit switch only in level and zone tracking mode. The
parameter "direction" defines the trigger for the relay, which means the relay is switched either
when the sensor position about limit value or the sensor position below limit. The hysteresis
defines the sensor position, where the limit switch (relay) is reset, relatively to the selected
threshold. Combining the parameters threshold and hysteresis a range can be defines, were the
limit switch is active. The relay configuration menus can be found in the setup I/O menu. For
more information refer to

The main menu mode consists of the main menus "quick setup", "test", "setup" and "service".
You can either leave the main menu level and return to the measuring mode or choose and enter
a main menu:
• Press ^ to return to the measuring mode (in this case a prompt appears and asks if you want
to save the changed data; choose "Yes" or "No" with the help of ↓ or ↑ and confirm by
pressing ^).
• If you do not want to leave the main menu level, press > to enter the first main menu
("quick setup") or choose another main menu with the help of ↑ or ↓ and enter it by
pressing >.

The submenu level consists of the first and second submenu level. The principle of choosing a
menu item is always the same:
• Press > to enter the first menu item or choose another menu item with the help of ↑ or ↓ and
enter it by pressing >.
i You navigate through the tree structure of the submenu level, finally you always reach the
parameter or data level.
• If you want to return to the main menu level without saving the input, press > and ↑ at the
same time.
• If you want to return to the main menu level and save your input, press ^ one or more times
depending on the level you are (pressing ^ results in moving one level upwards until you
reach the main menu level).

INFORMATION!
Like the lowest menu level (i.e. the parameter or data level) some submenus also offer the
possibility to make adjustments. The procedure is similar to the procedure on the parameter
level.
On the parameter level you see a list with one or more parameters or data. You can scroll
through this list using ↑ or ↓:
INFORMATION!
In this list all parameters or data which have been changed (i.e. they deviate from the default
setting) have a hook at the right end of their line (see position number 4 in the following
drawing).

4 Denotes the change of a parameter (this marking allows to simply and quickly identify all data which differ from the
default setting when browsing through the list); instead of the check mark there can also appear a lock symbol at this
position, it indicates a parameter that cannot be changed because of the parameter lock on the front.

9 Next menu item, reachable by pressing ↑ (if "- - -" appears in this line, this signalises the end of the list)
On the parameter or data level you have the possibility to change the decimal point, numbers,
units or settings. Before that you have to choose the desired parameter or data and open to edit
it as follows:
• Press > to open and edit the first list item or choose another item with the help of ↑ or ↓ and
press >.
i You are in the parameter edit mode now. All changeable values are highlighted and shown
reverse (if nothing is shown reverse, you are in the read-only view and you cannot change
the setting).
• Use ↑ or ↓ to change the highlighted area; if there are numerical values or a decimal point to
be changed, you can move the cursor with > to the desired position and change its value with
the help of ↑ or ↓.
• If you want to return to the parameter or data list and save your input, press ^; afterward you
can press ^ one or more times to return to the main menu.
• If you want to return to the next higher level without saving the input, press > and ↑ to the
same time.

meter measures the height of two distinctly different concentrations simultaneously. The two
heights from the last measurement cycle are held at the current outputs of the device and are
updated at the end of every further cycle.
2. Profile mode
Profile mode: The profile measurement mode allows to create a sludge level profile concen-

tration in g/l versus position. When the mode is selected a third measurement result page can
be displayed. On this measurement page a graphical representation of the measured sludge
level profile is shown which gives a general overview of the collected information. In this measuring mode the current channel A outputs a value proportional to the distance of the sensor
(height / depth) and the current channel B outputs a value proportional to the measured concentration in g/l.
3. Zone tracking
Zone tracking: The zone tracking mode allows to track a sludge level, thus the sensor will re-

main in the process in a parking position above the sludge concentration to track. When the
tracking time elapses the sensor will be moved down and the sludge level searching will be repeated. When the sludge level has been found the sensor is moved back in the parking position
again. When the sludge level is increasing and is reaching the parking position of the sensor,
its position will be moved up until the sludge concentration drops below the user defined limit.
Starting from this position the sludge level will be tracked again.
4. Manual operations

the last measurement value and the arrow keys on the keypad can be used to move the sensor
manually. This function is used for initial configuration and calibration of the device. It also
makes it easy to perform maintenance activities.

concentration is tracked first, while the sensor is moving down.
The factory settings of these values are:
1. Concentration fluff: 0.5 g/l
2. Concentration sludge blanket: 5 g/l
5.7.5 Definition in zone tracking mode
Applying the zone tracking mode requires additional setup of the following points:

5.7.6 Rake guard / external trigger
To protect the sensor and cable from being damaged or destructed by rakes or other moving
parts, the meter has two control inputs (CI1 and CI2), which function as NO contact control input
for the connection of an external limit switch (you have to buy this switch with another
manufacturer). Such limit switch can have 2 functions (depending which mode is selected in the
menu):
1. Rake guard
Rake guard: In this mode the limit switch is used to interrupt the sampling process in case the

DANGER!
To avoid damages or destructions, use a limit switch in all applications where a rake or other
moving devices may come in contact with the sensor or cable! The manufacturer does not
assume any responsibility for damages caused by the absence or malfunction of the rake guard
limit switch.
5.7.7 Timer / start signal
If there is no danger for the sensor or cable to be caught by moving devices (i.e. installation in
thickeners without stirrers) an alternative sampling mode controlled by the build-in timer can be
set.
• To enable the timer, the start signal has to be set to Timer. This can be done in the submenu
C1.5 start signal.
• After that the timer interval in minutes can be selected in the submenu C1.6 timer interval.

starting the first measurement:
First step: Change the working mode
• Change the measuring function to manual operation and lower the sensor by using the arrow
keys.
Second step: Find out the distances
• Lower the sensor head 0.3 m / 1 ft below the liquid surface and note the level as the blind
zone. Lower the sensor further until it reaches the bottom of the tank. (You can identify this
point by watching the cable got slack.) Pull up the sensor until you have about 5 cm / 2" of
clearance between the bottom of the clarifiers and the sensor. Note the level as the maximum
depth.

5.7.9 Calibration
INFORMATION!
Before leaving the factory the sensor is calibrated to offer an accurate measurement. Though it
might be necessary to re-calibrate the sensor during the lifetime of the system.
INFORMATION!
Even after the installation, a recalibration might improve the accuracy.
There are two forms of calibration. First is the zero point calibration, which has to be performed
if the measured value shows discrepancies in the low measuring range. Second is the calibration
of the concentration which has to be performed if the sensor shows discrepancies in the middle
or high measuring range.
Both types of calibration can be performed individually. However, for a full
recalibration, both calibrations have to be performed in the following order:
1. Zero point calibration (Step 3)
2. Calibration of the concentration (Step 3a, 3b and 3c)
OPERATION 5
INFORMATION!
As soon the user enters the calibration menu the current outputs are frozen. After completion of
the calibration cycle and return to measuring mode, the current outputs are reset to "0". If the
user needs the actual reading right away, please press arrow down to trigger a manual

INFORMATION!
When the zero calibration of the sensor is done in a medium with a higher turbidity than used for
the concentration reference point, it will cause invalid mapping of sensor values to the mapped
unit (g/l). The device automatically detects this failure and will report an application error
message "sensor calibration" on the message screen. The error will remain until the sensor is
correctly calibrated by the user.

5.8 Status messages and diagnostic information
INFORMATION!
Note the following information concerning the tables with the status messages in the following
subsections:
•
The devices groups all error messages and maps them according to their category and
importance; the following subsections and their tables represent the categories and the
order of importance. You find a short description of the error category in the table below this
admonition.
•
On the display you recognize the error category with the help of the character in front of the
message (e.g. all failure messages start with a bold "FFFF"); these characters are independent of
the used language, they were individually defined by the manufacturer.
•
If messages of the category FFFF, F and S appear and the device is in the normal measuring
mode, a triangle in the header appears (this triangle does not appear if only information is
shown).
INFORMATION!
Note that messages are shown in the GDC device for information purposes, too. They do not
effect any status change of the device or the measured values and are not planned in NE64,
VDI/VDE 2650 or NE107.
OPERATION 5
The OPTISYS SLM 2100 provides a status log book which is capable of storing the occurrence as
well as the disappearances of error of the classes: device failure, application failure and out of
specification errors.
An entry within the status log book consists of two lines
1. Line 1: Error class and message test
2. Line 2: Number, date and time (1 for occurrence and 0 for disappearance)
The latest status log entry is always displayed first, older values are stored in ascending order
based on date and time of the entry. The number of log book entries is limited to 128, as soon as
the limit is reached the existing entries will be overwritten by new entries.

or damage of the plant equipment.
WARNING!
Turn off the device during maintenance of the fan and fan filter.
1. Loosen the 2 nuts in the ventilation shaft.
2. Remove the ventilation shaft by pulling it up.
3. Remove the cover of the fan.
4. Clean or replace the air filter.
For assembling the ventilation please repeat the steps above in reverse order.
6.2.1 Cleaning unit (optional)
OPTISYS SLM 2100
The cleaning unit is an optional feature, nevertheless is it part of the standard menu to allow an
easy upgrade of the standard OPTISYS SLM 2100.
The sensor cleaning feature will be active either time based or cycle based. The cycle based
mode is only valid when the device is operating in level or profile measuring mode. In zone
tracking mode cleaning can be controlled only time based.
A measurement cycle is finished when the sensor reaches the bottom position in profile mode or
the position of the sludge level to search in level mode.
The sensor cleaning is a two phase process, in the bottom position the cleaning is enabled and
the sensor is moved back to the garage for cable cleaning. When the sensor has reached the
upper position the sensor cleaning phase starts and the sensor is moved through the cleaning
head in the garage. The number of passes is selectable in the cleaning menu.
Select the cleaning activation type in the menu first. In case of the activation mode is set to
"timer interval" the sensor cleaning is periodically performed when the selected time interval
has elapsed. By setting the cleaning activation mode to "counter interval" the sensor cleaning is
performed each time the selected number of measurement cycles has been conducted. Note
that the zone tracking measuring mode is not cycle based, in this mode for proper operation of
the sensor cleaning select the time based activation mode.
If an external water pump is connected to the device then the menu item "pump lead time" can
be used to delay the sensor cleaning process until pump system pressure has been setup. The
value of the pump lead time can remain at 0 seconds when no external water pump is in use.
64
The menu item "cleaning cycle" is defining the number of passes of the sensor through the
cleaning head. An external water pump can be controlled by the OPTISYS SLM 2100 when it is
enabled in the menu item external pump. Each cleaning cycle the external pump is switched on
when the water valve will be activated. Note that when the cleaning sequence is finished the
water valve remains open for 1 minute to empty cleaning system for protecting the system
against freezing at low temperatures.

The meter is using an optical sensor which travels through the media. Thus it can directly
measure the suspended solids concentration at different heights. The measurement of the
suspended solids content is based on the method of the transmission of light, which provides
precise measurement results independent of the sludge colour. The direct measuring principle
excludes incorrect measurements due to echo returns from walls or separating zones as well as
signal damping by fluff or floating sludge.
