Indication LEDs
The LED indication module comprising 15 LEDs is standard in 670 series. Its main
purpose is to present an immediate visual information for protection indications or
alarm signals.
Alarm indication LEDs and hardware associated LEDs are located on the right hand
side of the front panel. Alarm LEDs are located on the right of the LCD screen and
show steady or flashing light.
•
Steady light indicates normal operation.
•
Flashing light indicates alarm.
Alarm LEDs can be configured in PCM600 and depend on the binary logic. Therefore
they can not be configured on the local HMI.
