General notes
Introduction
These operating instructions describe the installation, operation and programming of the Softmaster MMP 2 controller.
We recommend that, while familiarising yourself with the operation of the instrument aided by these operating
instructions, you have immediate access to the operable controller in order to perform the described functions and
combinations. As certain functions are interrelated, it is advisable to follow the instructions in the given order.
Should problems or questions arise while operating the controller which are not described in these operating
instructions and/or cannot be solved, our customer service is always at your disposal.
Try to identify the problem as accurately as possible and record the actions and conditions under which it occurred.
This will enable us to offer you swift effective assistance.
Handling notes
Quick, repeated switching on/off of the controller should be avoided. Wait at least 5 seconds before switching 'on' or
'off' at the main switch.
Only operate the controller in compliance with the ambient conditions (e.g. temperature, moisture) stated in the
Technical Data. Always protect the controller against moisture.
It should never come into contact with condensation or splash water.
The warranty shall not apply if the controller is tampered with, altered, modified or repaired contrary to the instructions
described in this manual.
Before dismantling a defect controller, always write down the description of the error (failure effect).
The repair of a defective controller (irrespective of the warranty period) is only possible when the controller is
dismantled and returned to us with a description of the error.
The maximum electrical load capacity of the relay outputs and the total power rating of the plant should never be
exceeded.
The controller should only be used for its specified intended purpose.
Safety instructions
Always adhere to the following safety instructions:
The controller must be installed and operated in compliance with relevant standards (e.g. DIN, VDE, UVV) or in
accordance with regulations laid down by the respective country.
Some functions (e.g. manual filter change) allow direct manipulation of the plant (valves, pumps, etc.) without locking
or monitoring. These functions should only to be used by fully qualified personnel.
If you observe malfunctioning of the controller, switch it off immediately and inform the service personnel.
Do not attempt to repair the controller yourself (loss of warranty rights); instead always contact authorised service
personnel. This is the only way to ensure reliable and safe operation of the plant.
After a protective circuit (fuse, motor protection switch) has been triggered, attempt to eliminate the cause of
malfunctioning (e.g. clean the pump) before reactivating the protective circuit. Frequent triggering is always due to an
error which, in certain circumstances, may also cause damage to the controller.
Non-adherence to these instructions can damage the controller as well as the plant and may result in a loss of
warranty rights.
Installation and commissioning
Installation and commissioning should only be carried out by authorised technicians!
The connecting cables to the sensors should be kept as short as possible and clear of power cables. Close proximity
to strong electromagnetic radiators can lead to deviations of the display; in this case, separate interference
suppression measures should be carried out.
After installation, program the instrument with the plant-specific features and data (e.g. switch functions, conductivity
limit values, etc.). The data is permanently stored (also during power failure).

set clock !
Message after each switching on: “Power failure”. Check the time and, if necessary, set the time if “set clock !“ is
displayed. After this, the unit is without a real-time clock (plug-in card RTC/RS232).
After switching on or after voltage recovery, the controller starts with the last active status. A running regeneration
continues.
Check the plant for possible negative results due to power failure (e.g. exhaustion caused by washing for too long in
the regeneration stage “Wash out”).
All stored values remain stored even during a power failure.
Confirm the fault display with the “Horn” key.
Error message “Plant override”
Plant override
Regeneration triggering via contact at the start input or via to high
consumption while a filter is still beeing regenerated.
In multi-filter plants it can occur that a filter is in regeneration and a second filter is also waiting to be regenerated. This
status can occur if the soft water consumption is very high, e.g. when filling a swimming pool. If this scenario occurs,
the plant will only provide raw water to the consumers. If only soft water should be provided, the soft water supply to
the consumers has to be closed.
Wait until the current filter regeneration has finished and then open the soft water supply to the consumers. The
controller will always automatically complete regeneration of this filter.
Find and eliminate the fault and confirm the fault display via the ”Horn” key.
If regeneration is really necessary again (triggered via consumption measurement), regeneration will occur at the end
of the current regeneration.
If you have programmed a minimum regeneration interval, regeneration will be started after this period has expired.
With triggering via a contact at the START input, you have to start regeneration manually via the ”Run/Stop” key.
7/35
Error message “Minimum regeneration interval not achieved”
Min. reg. Pause
Regeneration triggering via contact at the start input or if consumption is too
high during the programmed time after a completed filter regeneration.
Confirm the fault display with the “Horn” key.
Regeneration requested via the water consumption is executed after the programmed period.
Regeneration triggering via the START contact is ignored. Check the plant and trigger a required regeneration
manually. The error message is subsequently deleted.
Error message “Maximum number of regenerations achieved”
Max. regenerat.
The entered maximum number of possible regenerations has been achieved.
The current status of the regeneration meter is shown in the SERVICE menu
under “Reg. meter”.
In addition to the error message, the yellow warning light “Chemical/brine low” lights up.
Confirm the fault display with the “Horn” key. The message is displayed until the regeneration meter is deleted.
Delete the regeneration meter in the SERVICE menu under “Reg. meter”.
Error message “Incorrect hardness measurement”
Err.hardn.meas.
The connected water hardness measuring instrument (e.g. Testomat 2000)
gives an incorrect current signal 4-20mA.
Confirm the fault display with the “Horn” key.
Check the settings of the current input. Programming has to correspond to the set signal level of the measuring
instrument. Check the signal levels in the SERVICE menu under “Diagnosis”.
Error message “Error total water hardness measuring instrument”
Error T2000 1
The connected water hardness measuring instrument (e.g. Testomat 2000)
for the total water hardness gives an alarm. The alarm signal occurs at
contact input ALC1.
Confirm the fault display with the “Horn” key.
Check the connected unit. The error display is deleted after the alarm signal has ceased.
Error message “Error soft water hardness measuring instrument”
Error T2000 2
The connected water hardness measuring instrument (e.g. Testomat 2000)
for soft water monitoring gives an alarm. The alarm signal occurs at contact
input ALC2.
Confirm the fault display with the “Horn” key.
Check the connected unit. The error message is deleted after the alarm signal has ceased.
Regeneration triggering via START contact is suppressed as, in the case of quality-controlled plants, the START
signal is usually triggered by the instrument for soft water monitoring if the hardness is exceeded.
8/35
Error message “Error operating position filter 1”
Error Filter 1
The central control valve or pilot distributor of filter 1 does not give a signal in
the operating position or is not running synchronously.
The signal does not occur at contact input SCV1.
Confirm the fault display with the “Horn” key.
Check the connected central control valve or pilot distributor of filter 1.
The error display is deleted after the fault has been eliminated.
Error message “Error operating position Filter 2”
Error Filter 2
The central control valve or pilot distributor of filter 2 does not give a signal in
the operating position or is not running synchronously.
The signal does not occur at contact input SCV2.
Confirm the fault display with the “Horn” key.
Check the connected central control valve or pilot distributor of filter 2.
The error display is deleted after the fault has been eliminated.
Error message “Chemicals low”
Chemicals low
The brine or chemical tank is empty.
The EMPTY signal occurs at contact input Prog1 and the input is programmed
as “Chemicals low” contact.
In addition to the error message, the yellow warning light “Chemical/brine low” lights up.
Confirm the fault display with the “Horn” key.
Check the brine tank and desalination valve or the automatic refilling of the measuring vessel. The error display is
deleted after the fault has been eliminated.
Error message “Chemicals overflow”
Chem. overflow
The brine or chemical tank is overflowing.
The overflow signal occurs at contact input Prog2 and the input is
programmed as “Chem. overflow” contact.
Confirm the fault display with the “Horn” key.
Check the brine tank and desalination valve or the automatic refilling of the measuring vessel. The error display is
deleted after the fault has been eliminated.
Error message “Regeneration stopped”
Reg. STOP/Hold
If the program has been stopped via an external switch (STOP input) prior to
or during regeneration and if you have programmed the alarm message for
the STOP input, the display "Reg. STOP/Hold" will appear as an error
message.
Confirm the fault display with the “Horn” key.
The display ceases as soon as the switch reopens and the program cycle is continued.

Description of relay outputs
Filter1 / Filter2 pilot distributor or central control valves 1 and 2
Connect the regeneration valves (central control valves) or pilot distributors which are controlled via an electric
change-over or impulse switch to these relay outputs.
Change-over: In the case of change-over switches, the output changes after each regeneration stage.
Impulse: In the case of impulse switches, the output switches for 40 seconds (terminal 7 or 7').
Pilot valves: For pilot valves for controlling regeneration valves like, e.g., Siata V250/V360 etc.
The neutral position of the relay is the same during de-energized control and in the operating position of the filter:
contact on terminal 6 or 6'.
Set the control type under menu option
"M"  BASIC PROGRAM  VALVE TYPE
If the regeneration valves or pilot distributors are equipped with a volt-free message contact for the operating position,
it is possible to connect them to the inputs "SVC1" and "SVC2". Faults of the valve / pilot distributor are then
monitored and evaluated by the controller in accordance with the programming (see SVC1/SVC2 service contact).
BV1 / BV2 Service valves Filter 1 and 2
The service valves of the filter can be designed as normally closed or opened. Please connect valves which are
normally closed to the terminals BV1-nc / BV2-nc. For safety reasons, the service valves should be designed in a
way that they open under driving voltage.
Note!
In the operating mode “double-filter serial connection“, the outputs BV1 and BV2 are used for filter change-over. For
this reason, they are not freely available. Please observe the plant example notes in the technical appendix.
Sync Synchronous contact / Regeneration message
(formerly: 8th-contact at MMP70/81)
After a power failure (e.g. during regeneration) or if faults occur, it is often necessary to synchronize the valves or pilot
distributors with the controller. It is even necessary to connect regeneration valves/pilot distributors with change-over
control and an odd number of (electric) regeneration settings to the synchronous contact. Due to this, the regeneration
valve / pilot distributor returns to the operating position after regeneration. The connection takes place at terminal
Sync - 8.
The connection Sync - PR can be used for the external display of the program cycle (regeneration) or for the control of
a contactor or magnetic valve during regeneration.
PR1 / PR2 Supplementary program 1 / 2
The volt-free outputs PR1 (supplementary program 1) and PR2 (supplementary program 2) can be used for various
functions:
Supplementary program 1
Supplementary program 1 is used, e.g., for the automatic filling of the brine tank or for the control of an additional
valve - prior to, during or after regeneration with a programmable operating time. If output PR1 is switched, the LED
"ZP1" lights up as a check.
Program the function under menu option (see basic programming “Aux prog. 1"):
"M"  BASIC PROGRAM  Aux prog. 1
Supplementary program 2
Supplementary program 2 can only be switched on and off twice during regeneration. If output PR2 is switched, the
LED "ZP2" lights up as a check.
Program the function under menu option (see basic programming “Aux prog. 2"):
"M"  BASIC PROGRAM  Aux prog. 2
Note!
Supplementary programs 1 and 2 are used for filter change-over in the operating mode “double-filter serial
connection“. For this reason, they are not freely available. Outputs BV1 and BV2 also have a special function. Please
observe the plant example notes in the technical appendix.
The two supplementary programs are also not freely available when using pilot distributors (e.g. Siata V250/V360).
(Programming: "M"  BASIC PROGRAM  Valve type  Pilot valves)
Please also observe the example in the technical appendix.
12/35
AL Fault message output ("Alarm")
Output "AL" is a volt-free change-over relay contact. During trouble-free operation, the contact between the terminals
22 - 23 is closed and the one between terminals 23 - 24 is open. During power failure or if an error occurs, the
contact between terminals 23 - 24 is closed and the one between terminals 22 - 23 is open.
The controller monitors several plant statuses. Output "AL" remains activated (terminals 23 - 24 closed) until the fault
ceases and is confirmed.
A fault is displayed with the red LED "Error message" and in the display.
The fault message signal at output "AL" is deleted by confirming the fault with the "Horn" key.
The fault display can only be deleted if the fault has been eliminated.
The following faults activate output "AL" and are displayed if the softening plant or valves/pilot distributors have been
equipped with the appropriate contacts:
Statuses which always trigger a fault message:
Power failure
Plant override (regeneration start during filter regeneration)
Error hardness measurement (if current input has been programmed as 4-20mA and no current is measured)
Error messages which occur depending on the programming:
Minimum regeneration interval not achieved
Maximum number of regenerations achieved (when reaching the regeneration meter)
Regeneration stopped via Stop input
Error Testomat 1 (ALC1)
Error Testomat 2 (ALC2)
Error Filter 1 (SVC1)
Error Filter 2 (SVC2)
Depending on programmed PROG1 input:
Brine/Chemicals low
Depending on programmed PROG2 input:
Brine/Chemicals overflow
Impulse / Dosing output
Use output "Impulse" to control a dosing pump if dosing should take place during operation. For this, a water meter
has to be connected to the input "WM1" or "WM2". The impulse interval in litres can be set (litre/impulse).
Example:
An impulse lasting 1 second should be given per 50 litres : L/Imp. = 50.0, I.duration = 1.0sec
A dosing distance of less than 50 L/Imp should not be entered for this water meter! The minimum dosing impulse
distance corresponds to the water meter constant.

Single-filter plant
Only one filter (filter 1) in operation, no soft water is available during regeneration.
Programming: “Single- filter

OPERATING MODE
Double-filter change-over mode
Alternately, one filter in operation, one filter in reserve/ready position or in
regeneration. Usually, soft water is always available.

2-F.serial
-
Double-filter parallel mode
Both filters in operation. Usually, soft water is always available.
With the parallel mode, only quantity-dependent regeneration triggering should be selected. Only enter the capacity of
one filter.
When commissioning the plant, both filters are regenerated, one after the other. After this, soft water is removed. After
removing a filter‘s soft water, a regeneration is started. At this point of time, both filters are half exhausted. After
regeneration, the regenerated filter has full soft water capacity while the other filter is available with its residual
capacity.
Programming: “2-f. parallel
”
Double-filter serial mode
Both filters in operation. Alternately, one filter is first filter, the other one is connected downstream as a “polishing
filter”. After removing a filter‘s soft water, the first filter is regenerated and the second filter becomes first filter. The
regenerated filter becomes “polishing filter”. Usually, soft water is always available.
Programming: “2-f. serial
T”
Note!
As the supplementary programs 1 and 2 are used for the filter change-over in this operating mode, they are not freely
available. Outputs SV1 and SV2 also have a specific function. Please observe the notes on the plant example in the
technical appendix.

Electric control of regeneration valves
It is possible to use central control valves or pilot distributors with up to 8
stage/positions with impulse or change-over control as well as pilot valves with 4
positions.
In the case of pilot valves, the number of stages is set to a maximum of 3 regeneration
stages as these valves usually have 4 positions.

Automatic calculation of the filter capacity
If the total water hardness varies strongly, it is also possible to automate the calculation of the filter capacity (available
soft water quantity). The total water hardness is measured with an analysis instrument (Testomat 2000/ECO) and
requested at the measuring input IN 0/4-20mA. The request interval for the calculation is one minute. If the alarm
contact of the analysis instrument is connected to the alarm message input ALC1, the controller measures the filter
capacity if the measuring instrument is not working correctly on the basis of the entered total water hardness.
If the filter capacity is to be calculated automatically, activate the function in the menu:
"M"  Basic program  Exchange cap.  Calc. f. cap.
Request the total filter capacity (available soft water quantity after regeneration) in the service menu:
"M"  Service  Exchange cap.
The remaining residual filter capacity or residual soft water quantity is shown in the operating display.
Regeneration
Regeneration start
Regeneration of an exhausted filter can be started via different triggering criteria:
- Manually by operating the “Run/Stop” key (press the key for 5 seconds)
- After removing the set soft water quantity (filter capacity)
- After the end of the set daily interval at the programmed time
- Via start impulse from the water hardness measuring instrument (Testomat)
Manual regeneration
A filter change takes place when starting regeneration manually. The filter in operation is regenerated and the filter in
the reserve/ready position is put into operation.
Quantity-dependent regeneration
In most cases, we recommend recording the removed soft water quantity and to regenerate the filter when the
calculated filter capacity has been reached. The controller calculates the filter capacity on the basis of the programmed
3
exchanger capacity (m x °dH) and total water hardness. Quantity recording takes place via a water meter in the
filter/plant output.
Program regeneration delay in order to avoid a regeneration taking place at an inappropriate time for the operation. A
necessary regeneration only starts at the set time, e.g. 20:00 (see "Regeneration delay").
During change-over mode, there is an immediate change to the filter in reserve and regeneration of the exhausted filter
is caught up on at the set time.
The filter can be overrun due to delayed regeneration. Additionally select a premature regeneration triggering (reg.
start at x% of residual filter capacity) to avoid this happening.
Time-dependent regeneration
If there should only be a time-controlled regeneration of the plant, program the daily interval and the time of
regeneration (regeneration delay = ON).
Quality-controlled regeneration
Using the internal control functions in connection with a water hardness measuring instrument (e.g. Testomat
2000/ECO), it is possible to construct a convenient and reliable plant. The water hardness measuring instrument
monitors the soft water hardness and sends a start signal to the controller in order to trigger regeneration if the set limit
value has been reached.
Due to the combination of the different control possibilities, it is possible to assure the greatest possible operating
safety.
Stop or delay the regeneration
Manually cancel a running regeneration at any time with the “Run/Stop” key. A regeneration can be delayed or a
running regeneration stopped via a contact at the “Stop” input.
Regeneration stages
Up to 8 regeneration stages can be programmed. Exception: In the case of pilot valves, the number of stages is set to
a maximum of 3 regeneration stages as these valves usually have 4 positions.
The minimum duration per stage is 1 minute (operating time of the valve/pilot distributor), the maximum duration is 99
minutes.
20/35
Regeneration delay
Programm regeneration delay ON and the corresponding time if a triggered
regeneration (e.g. due to reaching the filter capacity, via time interval or measured
hardness irruption) is to be carried out at a later time or only during a time window.
Regeneration only starts at the set start time “Reg. at: ”, e.g. 20:00. Enter the latest
time for the regeneration start under “Reg. to: “, e.g. 06:00.
This prevents regeneration taking place at an inappropriate time for the operation.

During change-over mode, there is an immediate change to the filter in reserve and regeneration of the exhausted filter
is caught up on at the set time.
In the case of single-filter plants, it is possible to preset whether the service valve remains open until regeneration or
whether it is closed immediately: “SV on (1-F,P)
” = service valve will close at start of regeneration.
Note!
The filter can be overrun due to delayed regeneration. Additionally select a premature regeneration triggering (reg.
start at x% of residual filter capacity) to avoid this happening.
Example for double-filter:
Premature regeneration triggering
Select this function for single-filter plants in order to guarantee a specific quantity of soft water for the following day.
Please additionally program “Regeneration delay” with the desired time for the regeneration start if regeneration is not
to start when the set residual filter capacity has been reached. This prevents regeneration taking place at an
inappropriate time for the operation.
REG. PRE-TRIG.
In the case of double-filter plants, there is an additional application possibility in
connection with "Regeneration before commissioning".
Set values of between 0 and 50% of soft water reserves for a premature regeneration
triggering. (Basic setting is 0% = no premature regeneration triggering)
Resid. cap. 0%
Prop.salting -
Economic (proportional) salting
Shorten the time of the salting stage in proportion to the consumption via the function “Economic salting” (proportional
salting). If, for example, regeneration is triggered at 30% of residual filter capacity, the salting time is only 70% of the
programmed time; but salting time is at least 10% of the programmed time.

If regeneration is to take place at a specific time, please additionally program “Regeneration delay” with the desired
time for the regeneration start.
Without regeneration delay, the filter is regenerated at the same time as the last regeneration.
The interval restarts after each completed regeneration.
Request the time - in days - of the next interval regeneration in the menu under

Select this type of triggering for double-filter plants at which bacterial contamination
problems, due to longer downtimes of the filter in reserve, can occur.
In order to still have soft water available during the regeneration time, trigger
regeneration via the "premature regeneration triggering“ early enough for soft water to
still be removed for approx. 2 hours.

Note!
It is not possible to combine this operating mode with the supplementary program 1 before a regeneration with
immediate filter change.
The manual service functions “Regeneration of the reserve filter” and “Filter change without regeneration” are also not
possible in this operating mode.
Minimum regeneration pause
If the softening plant is equipped with a desalination tank for brine storage, the interval
between two regenerations has to be at least 4 hours in order to achieve a sufficient
concentration of brine. Otherwise, the regeneration is insufficient and quickly leads to
an “Overrun” of the plant.
MIN. REG.PAUSE
10min
If regeneration can also be triggered by an analysis instrument (e.g. Testomat) due to hardness irruption, use the
minimum regeneration interval in order to avoid regenerating too frequently which is caused by premature triggering.
Premature triggering can occur, e.g., due to hardness increase caused by the counter ion effect or due to insufficient
washing out of the filter or if the measuring instrument is not functioning correctly.
If regeneration triggering (e.g. caused by reaching the max. quantity to be removed or externally by an analysis
instrument) occurs within this time, an error message “Min. reg. interval” is displayed and the alarm relay switches. The
regeneration has to be triggered manually.
Regeneration stages
Enter the number of regeneration stages (without operating position!) and the time of the individual stages according to
the used central control valves or pilot distributors. Up to 8 regeneration stages/positions can be programmed.
The number of stages is fixed to a maximum of 3 regeneration stages when using pilot valves as these valves usually
have 4 positions.
The following times are programmable:

Water meter
The controller has two independently operating water meter inputs. Water meter 1 is
used to record the used soft water quantity. The memory of this water meter is deleted
after each regeneration and, in case of parallel operation, also during the start of
regeneration. Water meter 2 can be used for dosing purposes or for measuring the total
consumption.
Set the impulse numbers for the contact water meter or turbines in the menu:

Consumption values for both filters are administered separately. The residual capacity
remains stored during a filter change.

an impulse is given as well as the impulse period. Please note that it is not possible
to enter an impulse interval in litres which is smaller than the basic number of the
water meter.
Alternatively, it is also possible to use the impulse output to duplicate the contact of the
water meter signal. We recommend this if you wish to control the hardness measuring
instrument (e.g. Testomat 2000 DUO) quantity-dependently. For this, please observe
the instructions of the connected hardness measurement instrument.
Valve monitoring (SVC inputs)
The controller has the two inputs SVC1 and SVC2 for monitoring the filter position.
Connect regeneration valves or pilot distributors with a contact (volt-free!) for the
operating position The controller can thus display malfunctioning of the valves (e.g.
motor failure) as error messages. Program the desired contact effect, test time (delay)
and alarm function (no alarm = only display message).
The menu for programming input SVC2 is structured as shown in the example for SVC1

If the alarm contact of the analysis instrument for checking the soft water quality is connected to the alarm message
input ALC2, a possible existing START signal is ignored and regeneration is only triggered quantity-dependently when
faults occur. Activate this function with:
"M"  Basic program  Funct. ALC 2  “Funct. alarm ”
The menu for programming input ALC 2 is structured as shown in the example for ALC 1 (see upper example).
Note!
If the plant is operated with a hardness monitoring instrument for regeneration triggering, we recommend monitoring
the trouble-free functioning by connecting the alarm contact of the Testomat to the input ALC2. Also avoid too frequent
regenerating, caused by faults at the hardness monitoring instrument, by entering a minimum regeneration interval. If
the hardness monitoring instrument triggers a new regeneration during this time, it is ignored and an error message
“Min. reg. interval” is displayed.
Function START input
If a regeneration is to be triggered quality-dependently, a water hardness measuring
instrument has to monitor the soft water hardness. When a set limit value has been
reached, the measuring instrument sends a start signal for triggering regeneration to
the controller.
In the case of double-filter plants, a filter change (only serial and change-over mode)
takes place and regeneration is started according to the programming (e.g.
regeneration delay).
"M"  Basic program  Funct. start
Function STOP input
During regeneration it might be necessary to interrupt this regeneration externally via a
switch (e.g. pressure switch in the input). Due to a contact at the STOP input, a running
regeneration can be interrupted or a pending regeneration delayed.

Function PROG1 input
The programmable input “Prog 1" is designed for special functions as level transmitter
input for the "Brine deficiency" alarm or the “EMPTY” level during automatic brine filling.
Program the desired contact effect, test time (delay) and alarm function. When
monitoring the desalination tank for brine deficiency, the input is requested at start of
regeneration. If the input is active = “Brine/Chemicals low” alarm, no regeneration is
triggered. Regeneration has to be triggered manually and the error message confirmed.
If the input is active during automatic filling of the brine tank (also see supplementary
program SP 1) and after the test time “Delay prog 1 “, output PR1 switches. During
simultaneous “Chemicals low” monitoring, a “Chemicals low” alarm message (e.g. tank
is still EMPTY despite an open filling valve) is displayed after the test time of the input.

Function PROG2 input
The programmable input “Prog 2" is designed for special functions as a level
transmitter input for the "Chem. overflow" alarm or the “FULL” level during automatic
brine filling. Program the desired contact effect, test time (delay) and alarm function.
When monitoring the desalination tank for brine overflow (input “Prog 2" active), a
“Chem. overflow” alarm message occurs after the test time “Delay prog 2“.
When filling the brine tank automatically (also see supplementary program 1), the alarm
function “Chem. overflow” cannot be selected. In this case, the input serves as “FULL”
level transmitter. If the brine tank is full (input “Prog 2" active), output SP 1 is switched
off after the test time “Delay prog 2“.

Function IN 0/4-20mA input
If the filter capacity calculation (available soft water quantity) takes place on the basis
of the measured total water hardness (in connection with an analysis instrument, e.g.
Testomat 2000/ECO/DUO), the setting of the signal input “IN 0/4-20mA” has to
comply with the measuring instrument:

When using the 4-20mA signal, the current signal is monitored for correct values. If the input current is lower than 4mA,
an error message “Error hardness measurement” occurs and calculation takes place on the basis of the entered total
water hardness.
T2000 DUO
If a Testomat 2000 DUO is connected in order to check the plant for hardness irruption/exhaustion and to measure
total water hardness, activate the function “T2000 DUO

max. h., maximum total water hardness
The input of the maximum hardness is used for the parameterization of the current
signal in order to calculate the total water hardness measured by the measuring
instrument.
min. h., minimum total water hardness
If the hardness falls below the value of the smallest possible total water hardness,
calculation takes place on the basis of the entered total water hardness.
