Page 15: General
Electrical isolation of each channel's power supply and use of a differential output amplifier ensure that the AVL microIFEM Piezo is also suitable for use in environments with severe interference. The high upper cut-off frequency on the other hand permits highly dynamic measurements.

Connect the RS232 OUT socket of the first AVL microIFEM to the RS232 IN socket of the second AVL microIFEM. Connect the 9.5 ... 36 V DC OUT socket of the first AVL microIFEM to the 9.5 ... 36 V DC OUT IN socket of the second AVL microIFEM.
Page 20: Temperature Range
E.g.: 12 V DC power supply: 15 W/12 V = 1.25 A, i.e. 6 racks can be cascaded. EnsureAlso ensure that the start-up power consumption (22 W for each unit) of all AVL microIFEM units does not exceed the maximum power output of the power supply! The power supply unit TR70 can supply up to four AVL microIFEM units.
Page 21: Avl Indisignal Operating Software
AVL IndiSignal is an integral part of parameterization in AVL IndiCom. Not only the data acquisition hardware, but also the AVL microIFEM is visualized. In this case, it is not necessary to do a separate AVL IndiSignal installation. • Set the relevant COM port in the IndiSignal section within the indicom.ini file.

Calling up a properties menu and reloading amplifiers or sensors will also deac- tivate the function. Reset Piezo Amplifiers Resets all installed piezo amplifiers in all available racks, i.e. sets their output voltage to 0 V or -8 V. AVL microIFEM Piezo 4P4x — Product Guide...

Refresh Sensor Data Reloads the sensor data of all connected sensors (AVL SDC, SID, SDB) into the relevant amplifier. 4.2.2 Rack View This section displays the selected AVL microIFEM. Devices can be selected in the status bar at the bottom of the window.
Page 24: General Information About Calibration
These parameters are stored in a non-volatile memory in the amplifier. If the TEDS (AVL SDC), SID or SDB functions are activated for a piezo trans- ducer, the system will read in type, serial number and sensitivity from the data connector or the database.
Page 25 Transducer Type / Serial Number  For documentation of your measured data in conjunction with AVL IndiCom, enter transducer type and serial number. Information If this amplifier has already been calibrated with a dead weight tester, the cali- bration parameters are locked for input (see Calibration with Dead-Weight Tester (IndiSignal Stand-alone Only) on page 49).
Page 26 The following options are available: 12, 20, 30, 50, 100 kHz Information The real filter frequencies may differ by around 10 %. Please note that low filter frequencies will lead to a signal delay. AVL microIFEM Piezo 4P4x — Product Guide...
Page 27: Sensor Data Management
Selecting the check box TEDS (SDC) activates the reading of the sensor data from a connected TEDS element (TEDS = Transducer Electronic Data Sheet). Depending on the type of AVL microIFEM, this can be a TEDS with FISCHER triax socket or with a 4-pin FISCHER socket (AVL SDC). The system will auto- matically use the optimal transducer sensitivity, depending on the set signal input range.
Page 28: Functions
A central sensor database is required to use this function. For installation and operation of the sensor database, use the program SensorAdmin, which is available under Tools on your AVL IndiSignal CD-ROM or in the IndiSignal installation folder. To activate this database, use the program ActivateSensorDataBase.exe, which is available in the AVL IndiSignal installation folder.
Page 29: Calibration Info Tab
AVL IndiSignal Operating Software input in AVL IndiCom is needed, because the software reads out the SCF auto- matically. If the maximum pressure that occurs during operation is not known, we recom- mend starting with a high initial value and then reducing it until the piezo ampli- fier goes into saturation (check by means of LED or overrange check;...
Page 30: Presettings
Presettings By changing entries in the indicom.ini file it is possible to specify settings which cannot be defined via the user interface. With AVL IndiCom, you can find these settings in the [IndiSignal] section of  the indicom.ini file. Entry...
Page 31: Sensor Data Management
Sensor Data Management Sensor Data Management The AVL microIFEM Piezo 4P4x enables you to read the characteristic trans- ducer data from a sensor data connector or a database (either manually or auto- matically via SID). This includes both calibration values and sensor runtimes.
Page 32  Total operating time of the sensor. When you start AVL IndiCom, the operating time counter in the amplifier is set to 0. As soon the amplifier gets a cylinder pressure signal, this internal counter recognizes the duration. When AVL IndiCom is stopped, the current counter content will be added to the field Total Operating Time.

To comply with the Electromagnetic Compatibility (EMC) directive it is neces- sary to mount a clamp-on ferrite core onto the input signal cable (included in scope of supply): Ferrit Core Piezo Amplifier Fig. 10 Position of ferrite core (thick cable) AVL microIFEM Piezo 4P4x — Product Guide...
Page 36: Piezo Signal Conditioning
You can choose between 0 V and -8 V offset voltage. NOTICE If the cylinder pressure signal is no longer detected (signal period > 1.2 s or amplitude < average value [V] +0.7 V), Continuous mode is automatically selected. AVL microIFEM Piezo 4P4x — Product Guide...
Page 37: Extended Output Range
If the LED on the flashes red, this indicates a brief or longer saturation of the amplifier. Reset the amplifier. If necessary, reduce the gain by entering a higher value in the Signal Input Range input field. Also check cable connections. AVL microIFEM Piezo 4P4x — Product Guide...

Page 39: Maintenance
Maintenance Accuracy On a regular basis (typically once a year): Check of the amplifier's accuracy. For this check, AVL provides the AVL Amplifier Calibration Unit. Article: TI04CALUA.01 Amplifier Calibration Unit Drift The high isolation resistance of piezo amplifiers at the time of delivery can only be maintained if the devices are always kept dry and clean.
Page 40 If there is still too much drift, dry the amplifier for 6 hours at +70° C. Information If none of these measures solves the problem, the amplifier needs cleaning inside as well. This should only be done by the manufacturer. AVL microIFEM Piezo 4P4x — Product Guide...
