7.6.4 Summary alarm
The summary alarm combines the states of all
MFx to a superior alarm-state of the
overall unit. For each monitoring function you may select if it is used for building the summary alarm state.
If at least one of the used functions is in the alarm state, the summary alarm is also in the alarm state.
If an optional failure-current monitoring is present, the detection of an alarm state or a breakage of the
measurement line (2mA inputs only) activates directly the summary alarm.
Alarm display
The symbol arranged in the status bar signalizes if there are active alarms or not.
Acknowledgment
: By acknowledging the summary alarm, the user confirms that he has recognized that
an alarm state occurred. The acknowledgment is done automatically as soon as the user selects the
alarm list to be displayed locally or via web browser or if the alarm state no longer exists. By
acknowledging only the flashing of the alarm symbol stops, the symbol itself remains statically displayed
until none of the monitoring functions is in the alarm state.
Logic output
The summary alarm can drive an output. The assignment of a digital output / relay to the summary alarm
is done via the settings of the corresponding output.
Reset
: The state of the summary alarm - and therefore of the used output - can be reset, even if there is
still an alarm active. So, for example a horn activated via summary alarm can be deactivated. A reset may
be performed via display, via web browser, a digital input or the Modbus interface. The logic output
becomes active again as soon as another monitoring function goes to the alarm state or if the same alarm
becomes active again.
Alarm state display
The digital or relay output assigned to the
summary alarm can be reset by means of the
<OK> key. So the active alarming will be
stopped. But the alarm state of the summary
alarm remains active until the alarm state no
longer exists.
