2 GENERAL GUIDELINES
General Electric IEDs are self-checking devices and will raise an alarm in the unlikely event of a failure. This is why
the commissioning tests ar
e less extensive than those for non-numeric electronic devices or electro-mechanical
relays.
To commission the devices, you (the commissioning engineer) do not need to test every function. You need only
verify that the hardware is functioning correctly and that the application-specific software settings have been
applied. You can check the settings by extracting them using the settings application software, or by means of the
front panel interface (HMI panel).
The menu language is user-selectable, so you can change it for commissioning purposes if required.
Note:
Remember to restore the language setting to the customer’s preferred language on completion.
Caution:
Befor
e carrying out any work on the equipment you should be familiar with the
contents of the Safety Section or Safety Guide SFTY/4LM as well as the ratings on the
equipment’s rating label.
Warning:
With the exception of the CT shorting contacts check, do not disassemble the device
during commissioning.
