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).

LED displays

The LEDs display operating statuses, plant functions and pending error messages:

Reg. F1 and Reg. F2 (green)

LED lights up: Filter 1 or filter 2 in regeneration.

LED flashes: A regeneration of the respective filter is triggered today at the set time (also see regeneration delay).

RP1 and RP2 (green)

LED lights up: Supplementary program 1 or 2 active, relay PR1 or PR2 switched.

LED flashes (only RP2): Relay RP2 not switched, “OFF” phase of supplementary program 2 active.

Dosing message (green)

LED lights up as long as the impulse output has been activated.

Warning message “Chemical low” (yellow)

LED lights up: The brine deficiency contact is active (also see PROG1 input).

Error message “Alarm” (red)

LED lights up: Alarm relay activated, error message not confirmed yet and error still occurring.

LED flashes: Alarm relay not active any more, error message has been confirmed but the error is still occurring.

As long as an error is still occurring, it is shown alternately with the operating display.

Operating displays

Each status change is stored in the status registration (e.g. manual regeneration, filter change).

Filter 1 in operation with 12.3m3 of residual capacity (still available soft water

quantity) and 21.4°dH of current total water hardness.

Display occurs with single-filter and double-filter plants.

or:

Operation F2 Filter 2 in operation

Operation F1 + F2 Filter 1 and filter 2 in operation (parallel or serial mode, filter 1 is first)

Operation F2 + F1 Filter 2 and filter 1 in operation (only serial mode, filter 2 is first)

Example: Filter 1 in regeneration: with regeneration stage R2 and remaining

stage time of 43 minutes. LED Reg. F1 lights up.

or:

Reg F2, R1: 7m Example: Filter 2 in regeneration: with stage R1 and remaining stage time of 7 minutes.

Supplementary program PR1 active prior to regeneration, remaining time of

10 minutes. LEDs Reg. F1 and ZP 1 light up.

Error messages

In addition to the displayed error messages, the red LED “Alarm” lights up or flashes.

Alternate display of all error messages and operating displays.

Each occurred error is stored in the error registration.

Error message “Power failure”

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”

Regeneration triggering via contact at the start input or via to high

consumption while a filter is still being 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.

Error T2000 1

Error T2000 2

Error message “Minimum regeneration interval not achieved”

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”

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”

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”

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”

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.

Reg. STOP/Hold

Error message “Error operating position 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”

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”

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”

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”

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.
