Special operating modes
The following "special operating modes" are displayed via the status LEDs and the
7-segment display.
F state (FAULT)
In the F state, the CPU of the D4x5-2 is in HOLD state, i.e. no software is running (D4x5-2
operating system is stopped).
The state occurs with faults to which the D4x5-2 operating system cannot respond.
The state is displayed as follows:
● All LEDs flicker red and
● The 7-segment display shows "F"
Possible measures:
● Check the CompactFlash card.
● Perform a commissioning again.
● Correct any overtemperature.
● Replace the D4x5-2.
The state can only be exited by switching the D4x5-2 off and on.
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.
