Various groups of parameters are grouped together in blocks to aid in the rapid na-
vigation through the large number of configuration screens. Selecting "YES" or
"NO" does not determine if control or monitoring is performed. The user’s selec-
tion has the following effect:
YES
.............. The configuration screens in this block are displayed and can either
be viewed ("Select" push button) or modifications can be made to the
parameters ("Cursor
→
", "Digit
↑
" or "Select" push buttons). This
does not disable or enable individual parameters, only if the individ-
ual parameters in this parameter block may be accessed for modifica-
tions.
NO
................ The parameters in this block are not displayed, cannot be modified
and are therefore skipped.

Maintenance call: sequence
0 to 9.999 h
A maintenance interval can be specified in this screen. After the engine has been in
operation for the number of hours configured here, a maintenance call message
(class F1 alarm) is displayed. Following the acknowledgement of the message, the
counter is reset to this value.
NOTE
If maintenance has been performed prior to the counter expiring, it is possible to reset the maintenance
counter to the configured value. The unit must be in code level 1 or 2 in order to achieve this. The
counter is reset in a 2-step procedure for safety reasons. The following procedure applies:
1. Step: Configure the desired number of hours for the maintenance call.
2. Step: Integration of the value which has been saved:
1. Exit the configuration mode and switch the controller into AUTOMATIC mode
2. Navigate to the display screen "
Service interval in 000h
" using the "Select" button
3. Press and hold the "Digit" push button for 7 seconds
