Electronic controller operating method for e.g. industrial truck, involves activating diagnostic signal applied to diagnostic output contact of output driver, and reading signal as input signal at diagnostic signal contact of driver

摘要

The method involves applying a preset diagnostic signal to a diagnostic output contact of an output driver, when a defined threshold value at a signal output contact of the driver falls below or exceeds, where the driver operates an electronic controller (10). Digital input signals are applied to the signal output contact such that a logistic signal value falls below or exceeds the threshold value, and the diagnostic signal is activated. The diagnostic signal is read as an input signal at a diagnostic signal contact. An independent claim is also included for a circuit arrangement with an output driver for operating an electronic controller of an industrial truck.
