RESET state (permanent RESET)
In the RESET state, the CPU of the D4x5-2 is in a permanent RESET, i.e.
● No software is running (D4x5-2 operating system is stopped) and
● The hardware is in a state that produces less power loss
This state occurs, for example, if the max. module temperature has been greatly
exceeded.
The state is displayed as follows:
● The RDY LED flashes red/yellow at 2 Hz
● The 7-segment display shows "8"
Possible measures:
● Correct the causes of any overtemperature.
● Ensure that the 24 V supply is stable without any power dips.
● Insert the fan/battery module.
The state can only be exited by switching the D4x5-2 off and on.
