4.3.8.3 Bit 0
With Bit 0 it is possible to control the interference in signal output.
Bit 0 = 0
Bit 0 = 1
4.3.9 Error Priority
Valid for all systems
Currently 10 single error bits (see Chapter 4.5.5 Error Monitoring) are set on the board
which can be summarized to an entire error message. The error priority enables the selec-
tion what single errors should initialize a total error message. The single errors can be
ranged into 2 different priority levels, briefly in a high and a low level. In case the dynamic
failure output is activated (see Chapter 4.3.6 System Byte), the distinction between both
failures in the output is possible, whereas this is not possible on static failure output. Both
levels are considered as failures of high priority then.
Selection frame:
ERROR-PRIORITY Y/N
Input frame:
ERROR-NO 1-8 >H--L---H< 9-16 >LL------<
NEW IN
As a new input the error priorities can be chosen in a different way:
with the input of 'H' - the high priority level
with the input of 'L' - the low priority level
with the input von '-' - the failure is blanked out on the total failure message
The input is divided into 2 groups from error 1-8 and 9-16. Should there be no change in
one of the groups, the old selection is adopted by the input of 'ENT'.
The significance of the individual error bits is described under "ERROR MONITORING"
(see Chapter 4.5.5 Error Monitoring).
4.3.10 Set Keyword
Valid for all systems
The master clock system can be protected from unauthorized modification of data with a
keyword. The keyword consists of a 6-digit combination of figures except 000000.
To avoid delays during commissioning the keyword should not be set until commissioning
has completely finished. The keyword should then be kept in a safe place.
Selection frame:
SET KEY-WORD Y/N
Input frame:
KEY-WORD
In the display the keyword chosen is shown with a "K".

when there is interference or no synchronisation or T-OUT has finished, there
is no reduction in amplitude or pulse output.
when there is interference, no synchronisation or T-OUT has finished, the am-
plitude and the pulse are modulated with 2 Hz. In this way any line interruption
in connected equipment can be monitored.
