figured time to restart expires.
The OFF state and ON state light emitting diodes can be found in multiple locations on
t
he device. 3 additional sets are arranged in pairs on the base of the optics cover. So
the LEDs can also be seen in many cases when it is not possible to see the display, e.g.
due to the mounting situation or because it is hidden from the operator’s position.
9.3.2 Network LEDs
The device has different LEDs for every network interface. These network LEDs are
located below the display.
CAUTION
T
he network LEDs are only used for diagnostic purposes and are not safety-relevant.
The safety function of the device is not impaired even if the status indicators are
incorrectly displayed or fail.
