Assembly Instructions
M8125-EN
Spare part Sonic transducer (O/ID T26416-1, T26416-2)
Purpose
Replacement of Sonic transducer (BB 1.x, BB 2.x)
Precondition
WARNING!
Danger for unauthorized persons!
Conversion work may only be carried out by
specialist staff who have been trained accordingly.
Therefore:
–Keep unauthorized persons away from the work
area.
NOTE!
Knowledge of the Instruction Manual is a
precondition for carrying outconversion work on the
unit.
Procedure
DANGER!
Danger to life caused by electric current!
Touching conductive parts causes a direct danger
to life.
Therefore:
–For all work on the electrical system, for
maintenance, cleaning or repair work,
disconnect from the mains or disconnect all
phases of the external power supply and secure
them against being switched on again. Check
unit is isolated from power supply.
WARNING!
Danger of crushing due to rolling away or
tipping
With an uneven floor or when the castors are not
locked, there is a danger that the unit tips over or
rolls away causing crushing.
Therefore:
–Only install the unit on an even floor.
–Ensure that the castors are locked.

1. Proceed as follows in order to cool down the unit and empty
the mould (mould evacuation)
Display menu page Functions.
Select the function Cooling and activate with the key.
Select the function Mould evacuation and activate with the
key.
The activated function is indicated with the symbol.
2. Main switch off, remove the plug from the mains and empty
the unit.
3. Proceed as follows to replace the sound transducer (BB 1.x,
BB 2.x) at measuring ciricuit x:

Fig. 2: Connection of sound transducer
(BB 1.x, BB 2.x) to 8 pin cable plug.
Disconnect the cable plug from the socket (X 402.x)Fig. 1) at
the evaluation unit.
Disassemble screws (Label 1 Fig. 1) and remove cover.
Disconnect sound transducer (BB 1.x, BB 2.x Fig. 1) .
Open the 8 pin cable plug and replace the sound transducer
(BB 1.x, BB 2.x) with a new one (connect cable plug Fig. 2).
Close 8 pin cable plug and connect it to the socket (X 402.x
Fig. 1).
Connect new transducer (BB 1.x, BB 2.x Fig. 1) (tighten with
max. 30 Nm torque).
Mount covers with screws (Label 1 Fig. 1).
4. Reconnect mains plug and switch on main switch.
5. Press the key to switch on the unit and check it for leaks.

6. Proceed as follows to calibrate the flow rate metre:
When setting parameters set DFM recognition to the
"integrated" value (in Settings / Miscellaneous), continue with
Step 7..
When setting parameters set DFM recognition to the "modular"
value (in Settings / Miscellaneous), continue with Step 8..

operation
Integrated operation
7. Proceed as follows to calibrate the corresponding flow rate
metre:
(from software version SW51-1 0849B)
In normal operation operate the device at 40 °C for at least 10
minutes.
Only in the case of water units:
If present set the parameter Pressure relief with unit OFF at
Setting / Miscellaneous to "OFF".
Switch the unit off using button and wait at least 10
seconds.
Set corresponding parameter Flow rate ext. 1..8 Calibration at
Service / Calibration / Flow rate external 1 to 4 or Service /
Calibration / Flow rate external 5 to 8 to "ON".
The flow rate is calibrated automatically.
Only in the case of water devices:
If present set the parameter Pressure relief with unit OFF at
Setting / Miscellaneous to "ON".
Switch the unit on with the key.

operation (<SW51-1 0849B)
(up to software version SW51-1 0849B)
In normal operation operate the device at 40 °C for at least 10
minutes.
Set corresponding parameter Flow rate ext. … offset at Service
/ Calibration / Flow rate external 1 to 4 or Service / Calibration /
Flow rate external 1 to 4 to "5 L/min".
Close the corresponding shut-off valve between the feed and
return line and wait for 1 minute.
Read current Flow rate.
Set the parameter Flow rate ext. … offset according to the
following calculation:
Flow rate ext. … offset new = 5 –flow rate as it currently stands
Opening the shut-off valve

8. Proceed as follows to calibrate the corresponding flow rate
metre:
In normal operation operate the device at 40 °C for at least 10
minutes.
Only in the case of water devices:
If present set the parameter Pressure relief with unit OFF at
Setting / Miscellaneous to "OFF".
Switch the unit off using button and wait at least 10
seconds.
Select the module affected e.g. "A1" with the or
buttons.
Set parameter Flow rate calibration at Service / Calibration /
Flow rate to "ON".
The flow rate is calibrated automatically.
Only in the case of water devices:
If present set the parameter Pressure relief at unit OFF at
Setting / Miscellaneous to "ON".
Switch the unit on with the key.
9. Inspection of calibration of Flow rate meter
In normal operation operate the unit at 40 °C for at least 5
minutes following calibration.
Close the corresponding shut-off valve between main and
return lines.
Flow rate returns to 0 L/min.
If this is not the case repeat the Flow rate meter point.
Punkt Durchflussmessung kalibrieren für jeden ersetzten
Schallwandler wiederholen.
10.Switch the unit off by press the key.
11.Main switch off.
