Schaeffler SmartCheck User Manual page 31

The status LED is located above the fixing screw cover (item 1):
The LED behaves differently depending on whether you have only just switched on the SmartCheck device or
whether it has already started up. Relevant details can be found in the following sections.
Status LED immediately after switching on the device
Once the device is switched on, the LED alternates between red and yellow. Do not disconnect the device from
the power supply during this phase. Once the start-up process is complete, the status LED indicates the current
alarm status.
Status LED after starting up
Once the device has started up, the status LED changes from flashing red to yellow to green. The LED then lights
up as follows depending on the status of SmartCheck:
LED
Green
Yellow
Red
Flashing (green)
Alternating red and
yellow
You can use the SmartWeb software to specify that the status LED should not indicate the
alarm status. This setting remains in force when the device is reset unless the device is reset
to the factory default settings: in this case, the alarm status display is reactivated.
RS485 LED
The RS485 LED is located to the left of the fixing screw cover (item 2):
This LED lights up blue when SmartCheck is connected to the RS485 network. It flashes when data is being
exchanged.
Communication via RS485 is not currently supported.
ETH LED
The ETH LED is located to the right of the fixing screw cover (item 3):
This LED lights up blue when the SmartCheck device is connected to the Ethernet network. It flashes when data is
being exchanged.
