G4 Multi Channel Weighing Instrument7. TroubleshootingGeneralDuring installation and maintenance of the G4 Instrument, the sub menu‘System Information’ can be useful for solving possible I/O module and Ethernet relatedproblems.The instrument reports detected errors on the display. Error codes can also be read viacommunication.When an error is detected for a scale, all digital outputs are set passive and theanalog outputs are set to 0 V or 0 mA for outputs configured for that scale.The output signal ‘In Process’ is set passive if an error is detected.The optional fieldbus interface adapters have LED’s for indication of status.Error codesThis part provides explanations of the error codes.Some errors are displayed on the instrument display, containing a description ofthe error and the error code.Reading error codes is done by Modbus and by the optional Fieldbus. Error coderegisters are ‘Instrument error’, ‘Command error’ and‘Scale 1: Error code’ to ‘Scale 8: Error code’ (see section '6 Communication').The error codes are divided in four groups, depending on their origin:• Weight errors• Start-up errors• General errors• Set-up errorsoccur when transducer signals or weight values goout of given ranges.occur only during start-up.usually occur due to faulty entries from the front panel,alternatively invalid data or not allowed commands fromthe control unit.can only occur during instrument set-up.On the following pages a summary of all error codes is given(note that code 000 always means 'no error').Note that there are some error codes of internal type not described below. If an errorcode is displayed that is not listed below try restarting the instrument and if the errorpersists please contact your supplier.7-1
