System LED S1 and S2

The RTCU is equipped with two system LED's, which shows the status and possible errors of the
RTCU device.
The different patterns are listed in the table below. If the color of the system LED S1 is yellow, the
device is actively communicating with the RTCU IDE (or another program, supporting the RTCU
RACP protocol).
The LED S2 is signaling either the cellular module activity or if all other LED's are off, that the
RTCU is in the "wait for event" low power state.

The device is initializing, preparing to start the application.
The device is installing an update. Depending on the kind of
update, it may take some time. The progress can also be
observed on the display.
The device has been forced into recovery mode with the use
of the system switch. The application is not executing.
The device is executing the application program
2
2 The device is executing the application program, while
charging the internal back-up battery.
A runtime error has been detected in the program.
Use the RTCU IDE to obtain the fault log.
The device has lost its firmware! This can only happen if,
2
during a firmware upgrade, the RTCU device loses power or
the communication is lost completely. In this case, simply
upload the firmware to the device again.
Execution speed is different from full-speed.
The device is booting, initializing the system
