8.6.1 Alarm status (3)
Fig. 31 Alarm status
Description
A fault in the system or one of the components monitored can
cause an alarm or a warning. Besides the fault signal via the
alarm and warning signal relay and the red indicator light on CU
352, an alarm can also cause a change of operating mode, for
instance from "Normal" to "Stop". A warning only causes a fault
indication.
The table shows the possible causes of fault together with an
alarm code, and whether they result in an alarm or a warning. It
also shows to what operating mode the system will change in
case of alarm, and whether restarting of the system and resetting
of the alarm is manual or automatic.
The table also shows that the reaction to some of the fault causes
mentioned can be set in the menu "Settings". See sections
8.7.26 Soft pressure build-up (4.3.3) and 8.7.56 Monitoring
functions (4.4) to 8.7.66 Pressure relief (4.4.8).
