Startup activities of the TIM 3 and TIM 4
Introduction
During startup, the LEDs on the front panel of the TIM 3 / TIM 4 have a different significance
than during normal operation. They are optical indicators of the various startup phases and
provide detailed information about any errors detected during startup.
LED displays during startup
The following table summarizes the startup phases.

Explanation
1
Power ON
All LEDs light up at the same time.
2
RAM test
Starting with LED 6 (DCF77), the LEDs go off one after the other at intervals of
approximately 10 seconds. If an error is detected during the RAM test, LED 1 (SF
group error)
remains lit at the end. If everything is OK, the TIM changes to phase 3.
3
Service mode
After all the LEDs have gone off, all LEDs light up again for 5 seconds. During this time,
the user can force a default startup (see below) using the reset button. Otherwise, the
TIM changes to phase 4.
4
Software startup
All the LEDs go off again and then light up again one after the other starting with LED 2
(TXD). At this stage of startup, the individual steps of the software startup are signaled
by the LEDs. The LEDs are either lit continuously or flash. The following table lists the
exact meaning of the individual LEDs when lit continuously or flashing during this
startup phase 4.
5
Startup completed
The LEDs go off if phase 4 is completed free of errors and then have the significance
according to their definition in normal operation.
