INJECTOR POWER DRIVER IPOD COIL INJECTOR POWER DRIVER IPoD COIL Power control rack for solenoid injectors Acurate•Fast•Repeatable PRESENTATION The EFS8532 rack is a power module to drive injector using magneto-electric technology. It integrates different driving modes and advanced functionalities permetting to drive any injector on the market. INJECTOR TESTS • Production • R&D • Quality • ACCURATE: Parameter adjustment is handled by means of specific software in real time. • FAST: You can test different types of injector without changing the IPoD. • REPEATABLE: There is no new adjustments to be made when you change an IPoD on a bench.

SYSTEM DESCRIPTION It is made up of: • an electronic rack to control the injector • xIPoD configuration and operating software • connection cables Software xIPoD 10 • Windows • Ethernet link with the rack Electronic rack Electronic rack: 19’’ 1U (440 mm x 360 mm x 44 mm) MAIN FUNCTIONS • Double driving power supply: - one programmable source from 6 to 50 V - one programmable source from 25 to 150 V • Independant unit with internal pulse generator • Injection frequency up to 5 injections per rev at 3000 rev/minute • Graphic interface to control all the injection parameters • Fully protected...

DRIVING MODES The driving modes are derived from a basic cycle featuring all the necessary phases. • • • • • • preload phase boost phase pull-in phase holding phase discharge phase demagnetization phase BLUE Injector voltage PINK lnjector current YELLOW Injection command Complete injection • End OF Travel detection (EOT) • Capacity discharge simulated for the pull-in phase • Programmable injector disch

CONTROL SOFTWARE xIPoD is the configuration/setup and operating/control software. Depending on the type of IPoD selected, only the useful parameters are displayed. Saved/previous configurations can also be recalled. • A single xIPoD session to drive several IPoDs on the same RS 485 link. • Automatic detection of the types of IPoD available on the RS485 (IPoD coil, IPoD coil 6 channels, IPoD piezo, IPoD piezo 6 channels). • Possible synchronization of all the parameters of the same connected PoDs. You develop your injector by changing your settings in real time IPoD coil can generate any...

You have a fully configurable equipment General parameters These parameters are used to define the battery voltage (VBAT), the high voltage (VHT) and the maximum injection length that be applied to the injector. □_General parameters You preload the coil for a quick response from the request to open the injector PRE-LOAD parameters These parameters are used to define whether there is a load step (value at 1) with stabilization of the current at an adjustable value of 0 to 30 A during a specified time.

You accelerate (or not) the opening of the injector BOOST parameters This parameter is used to define the IBOOST parameter : 0 : no boost step 1 : defined by battery voltage (VBAT) 2 : definec by high voltage (VBOOST) 3 : use of simulatd capacity You ensure a good opening of the needle PULL-IN parameters The current can be adjusted from 0 to 30 A. 1: VBAT (battery voltage) or 2 : VHT : (high voltage).

The EOT (End Of Travel) determine the complete opening of the solenoid valve. The IPoD detects this instant through the variation of the current. A logic signal returns this information. BLUE Injectoi voltage PINK Injectoi current ; detection YELLOW Injection command CLOSING parameters You close the injector as well as possible CLOSING parameters The EV current decreases quickly to 0 by connecting the EV to a high voltage defined by the parameter VMZENER - dischade voltage. You hold/keep the needle open HOLDING parameters The EV current is maintained between the value I-HOLD and I+ HOLD by...

You choose your driving mode Pulse generator The driving can be triggered either: • an external input or • by an internal pulse generator You offset the impedance Rising time You offset the harness impedance by adjusting the rising time of the current in the injector. It allows you to find the Vbat voltage to be applied to the injector in order to have a given rising time.

Synchronous demagnetization current with current chopping for 300 ps.
