Condition monitoring indication
If the terminal includes condition monitoring functions that are not directly related
to any protection functions of the terminal or to the internal condition of the
terminal, they are indicated in the assisting window by the message SUPERV and
an explanatory text, see the example below.

Test modes
There are various test modes for each of the following four categories:
• Function
• Control
• MIMIC
• I/O test
• IRF test
6.4.1.
Function test
The outputs of a function block can be activated locally via the HMI or externally
via serial communication. The outputs are activated by using control parameters of
the function.
For further details of functions, refer to the CD-ROM Technical Descriptions of
Functions (1MRS750889-MCD).
6.4.2.
Control test
The system provides a general interlocking bypass mode (parameter “Interl bypass”
in
MAIN MENU/Control/General
) that overrides all interlocking signals.
Activation of the interlocking bypass mode activates the interlocking enable signals
of all control objects. Thus, all control actions are possible, and the enable signals of
controllable objects are not checked while the objects are commanded. As long as
the mode is active, the Interlocking LED indicator on the HMI is red and flashing.
Additionally, the assisting window of the MIMIC view will indicate the special
condition.
