However even if the value returns to within a valid range, the error remains continuously
present if the 'freeze' is requested with4849
AnaStopHoldOrReset
= 1.
With these parameterization options, the appropriate error handling can be found for any
system.

Electronics monitoring
Electronics self-tests are performed to monitor the safe operating state. The following table
shows what is monitored and which errors are set in each case. The tests that are run once
when the control unit is booted are described in
10.7 Emergency shutdown errors
shows which errors lead to an emergency
shutdown of the system or which disable a system start. Each individual error is described
in detail in

5.5.1
Voltage references
The PANDAROS DC 6-06 uses a voltage reference value for ratiometric measurement
at analogue inputs. The value must be within software-internal fixed limits or the error
3081
Err5V_Ref
is output and the setpoint input cannot be corrected.
5.5.2
RAM memory test
All of the used RAM memory is tested while the program is running. The address of the
cell that is being currently tested is shown in 3895
RAMTestAddr
. The test value that is
currently running can be taken from 3896
RAMTestPattern
. If a fault cell is detected,
these two displays are held, the error 3078
ErrRAMTest
is activated and a fatal error is
generated.
