Switch boards - Import export

Modular equipments for technical training at engines under realistic operating conditions: under load at the engine dynamometer. Applications depending on scope of delivery: torque, power = f(speed), specific consumption sfc = f(speed, power) (gravimetric, selectable automatically). Above tests can be carried out in different ways: conventionally or supported by the test bed's MP Computer or with automatic documentation by directly printing or by PC thermal balance (PC required), real function of a transmission (automatic transmission only with PC), p-V-diagram (PC required). Functions of engine and engine control depending on the load may be demonstrated by using motor analysers, exhaust gas analysers and further measuring instruments. Model-specific error-switch boards are extending the demonstration varieties and are enabling a practical error diagnostics. Comparison of different engines under a certain aspect within one lesson.

This involves a play-free electronic switching cam encoder (abbreviated to: NOCN) with a maximum of four galvanically separated switching outputs (cams), which can be set by the customer and which are activated or deactivated depending on the relevant position of the drive shaft. A parameterisable multiturn absolute encoder with CANopen interface plus the switching cam encoder printed circuit board with separate controller are integrated into the compact housing. The encoder's CANopen position signal and the switching outputs can be parameterised separately. Parameterisation is carried out via the relevant CANopen objects in accordance with the encoder profile according to CiA, DS 406, revision 4.01. The NOCN has a fault monitoring system which outputs a fault message via the CANopen bus (emergency message) on detection of a fault.

This involves a play-free electronic switching cam encoder (abbreviated to: NOCA) with a maximum of four galvanically separated switching outputs (cams), which can be set by the customer and which are activated or deactivated depending on the relevant position of the drive shaft. A parameterisable multiturn absolute encoder with analogue interface plus the switching cam encoder printed circuit board with separate controller are integrated into the compact housing. The analogue signal and switching outputs can be parameterised separately using multifunction pins (MFP and PRE) in the connector.

This involves a play-free electronic switching cam encoder (abbreviated to: NOCE) with a maximum of four galvanically separated switching outputs, which can be set by the customer and which are activated or deactivated depending on the relevant position of the drive shaft. A parameterisable multiturn absolute encoder with SSI interface plus the switching cam encoder printed circuit board with separate controller are integrated into the compact housing. The SSI interface can be preset, the code direction can be set and the switching outputs can be preset.
