The user has to enter the test mode (MAIN MENU/Tests/General/Test
mode) before testing the IRF state. IRF is activated by setting the parameter
"Activate IRF" (MAIN MENU/Test/General/Activate IRF) to
"Activate IRF". This will release the IRF relay contact and send the IRF error
activated event (E57).
The test mode is cancelled by setting the "Test mode" parameter to "Not active" or
by powering up the relay. If the user does not cancel the test mode, it remains on and
the Ready LED indicator remains blinking.

The HMI includes three protection LED indicators. The basic functionality of the
LED indicators is described below. In addition, there are function block -specific
LED indicator operations that are described in more detail in the function block
manuals (refer to the CD-ROM Technical Descriptions of Functions, 1MRS750889-
MCD).
LED indicators can be latching or non-latching:
• Non-latching type of LED indicator goes automatically out when the fault
disappears (the protection stage resets)
• Latching type of LED indicator remains lit, although the fault disappears, until
cleared by pressing [C] for two seconds
