The product may only be used and operated by qualified personnel capable of observing the necessary safety precautions. All accessories and equipment used with the product must be supplied or approved by AVL. The operating prin- ciple of this product is such that the accuracy of the measurement results depends not only on the correct operation and functioning of the product, but also on a variety of peripheral conditions beyond the control of the manufacturer.
Always place the device in a position that allows air to circulate freely through the device’s venting aperture. CAUTION Danger of injury The device weights more than 18 kg, therefore make sure to use the appropriate utilities for transportation. F-FEM-DIO — User’s Guide...

Preface General Information About the F-FEM-DIO The F-FEM-DIO (Fast Front End Module Digital In Out) is a new type of FEM (Front End Module). It is part of a family of Front End Modules that operate together in a network. This F-FEM belongs to a new generation of devices for which real time data communication is ensured in the PUMA Open system.
NOTICE This documentation does not and cannot replace adequate training! Naming F-FEM-DIO: Fast Front End Module Digital In Out System Environment The figure below outlines schematically how F-FEMs are integrated with the PUMA Open test bed system. Fig. 2 Example of a system environment 1..
2..IEEE 1394 Interface adapter, via which all F-FEM signals are transferred to/from the PUMA Open system. 3..F-FEM-DIO, connected to the PUMA Open system via an F-FEM-DAC (serial line between F-FEM-DIO and F-FEM-CON). 4..Engine test bed – digital signals are transmitted to/from the engine using digital sensors (switches, actuators, etc.).

F-FEM-CON, F-FEM-DAC and F-FEM-CNT. The power supply for the F-FEM-DIO is also integrated into this interface. The F-FEM-DIO can be used with PUMA Open or with automation systems from other manufacturers. FEMs Classic (older generation of FEMs) and F-FEMs (new generation) can be operated parallel to each other in the PUMA Open system.

Installation Installation 3.1.1 Unpacking Normally, the F-FEM-DIO is delivered in a cabinet with the wiring already done. Component parts must only be exchanged in the case of replacements or system extensions. Information Please check the contents with the items as indicated under "Scope of Supply".
If the power supply has been switched on and the pin assignment is correct, a figure or 2 strokes appear on the seven-segment display on the front side of the F-FEM-DIO. If this is not the case, check all steps of the installation. WARNING: Do not open the closed module case! There are no parts in the interior of the device that need to be exchanged.
Installation 3.1.7 External Dimensions Fig. 6 External dimensions of F-FEM-DIO with cable connectors Software Installation The on-board software necessary for operation has already been installed on the connected F-FEM-CON, F-FEM-DAC or F-FEM-CNT. The on-board software can also be loaded by the automation system during the initialization phase (please see the relevant documents).
This requires low grounding resistance and compliance with the high frequency rules regarding installation, wire types and contacting. The F-FEM-DIO is electrically isolated from the 24 V DC supply. For safety purposes, the case is connected to the ground via a PE and via the DIN rail (to avoid radio frequency interferences).

Operation Operation General The F-FEM-DIO is controlled by an F-FEM-DAC, F-FEM-CNT or F-FEM-CON via a serial connection. The digital inputs are read in cyclically. The digital outputs are also cyclically updated. The serial transfer is protected and time-controlled, so that the relays of all outputs are released into their normal position in the case of a protocol failure (e.g.
Digital Outputs X33 and X34 When switching inductive loads, the negative anode potential must be limited to max. 60 V (by means of a Zener diode or a recovery diode). Otherwise, the relays might be damaged by the voltage spikes. F-FEM-DIO — User’s Guide...

Common has been designed as a double contact to simplify the wiring. Please also see figures 6 and 7. If the F-FEM-DIO is connected to an F-FEM-CNT or F-FEM-DAC, the WD-live contact can be used as a "fast" digital output (up to 100 Hz).
