FUNCTION BLOCK
The AQ300 series devices
–
independently of the configured protection functions
–
have some
common functionality. The Common function block enables certain kind of extension this
common functionality:
1.
The WARNING signal of the device
The AQ300 series devices have several LED-s on the front panel. The upper left LED
indicates the state of the device:
•
Green means normal operation
•
Yellow means WARNING state
•
The device is booting while the protection functions are operable
•
No time synchron signal is received
•
There are some setting errors such as the rated frequency setting does
not correspond to the measured frequency, mismatch in vector group
setting in case of transformer with three voltage levels, etc.
•
Wrong phase-voltage v.s. line-to-line voltage assignment
•
No frequency source is assigned for frequency related functions
•
The device is switched off from normal mode to Blocked or Test or Off
mode, • the
device is in simulation mode
•
There is some mismatch in setting the rated values of the analog inputs.
•
Red means ERROR state. (This state is indicated also by the dedicated binary
output of the power supply module.)
