technology)

The yellow LEDs I1 and I2 indicate the status of the
dynamic safety code, which is forwarded on to the safety
motor. Since the frequency of the safety code decreases
with the number of AS-Interface slaves that are connected,
the LEDs may flicker noticeably. This is a normal operating
state.
