G4 Multi Channel Force Instrument

10. Troubleshooting
General
During installation and maintenance of the G4 Instrument, the sub menus
‘System Information’ and ‘Maintenance / Diagnostics’ can be useful for solving possible
problems related to I/O modules, Ethernet, Serial Communication etc.
The instrument reports detected errors on the display. Error codes can also be read via
communication.
When an error is detected for a Function Block, all digital outputs are set passive
and the analogue outputs are set to 0 V or 0 mA for outputs configured for that
Function block.
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 codes
This part provides explanations of the error codes.
Some errors are displayed on the instrument display, containing a description of
the error and the error code.
Reading error codes is done by Modbus and by the optional Fieldbus. Error code
registers are ‘Instrument error’, ‘Command error’ and Function Blocks error code
registers (see chapter 7. Communication).
The error codes are divided in four groups, depending on their origin:
•
Force errors occur when transducer signals or force values go
out of given ranges.
•
Start-up errors occur only during start-up.
•
General errors usually occur due to faulty entries from the front panel,
alternatively invalid data or not allowed commands from
the control unit.
•
Set-up errors 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 error
code is displayed that is not listed below try restarting the instrument and if the error
persists please contact your supplier.
