4. Operation of the System
Alarm Mode
As soon as alarms are triggered, only the inputs in alarm status are displayed, arranged by
input number. Contrary to the alarm LED’s at the MDO front panel, the display of alarms does
not flash.
Measurement values that are over the full-scale range will trigger all alarms caused by values
exceeding the limits.
Alarm types are latching or non-latching. All signals that have exceeded the limit values are
latching alarms. It is possible during measure mode to change between alarm list display and
list display by pressing the ENTER button. If during list display new alarms are triggered, alarm
list display is not switched automatically.
Non-latching alarms
As soon as a new alarm is triggered, it is displayed according to the three display types described
below. When the signal is within the limits again, the alarm is no longer displayed, regardless
of whether the alarm has been acknowledged or not. For non-latching alarms, the RESET key
has no effect.
Latching alarms
As soon as a new alarm is triggered, it is displayed according to the three display types described
below. When the signal is within the limits again, the alarm continues being displayed, because
it is latching. If the signal is within the limits again and the alarm has been acknowledged, the
alarm display is stopped by pressing the RESET key. If the signal is still beyond the limit, or if
the alarm has not yet been acknowledged, pressing the RESET key has no effect.
List Display
In this display mode, the current input data is displayed in a list. If more inputs are available
than can be displayed at the same time, flashing arrows appear to the far right of the title bar
(Ï and/or Ð) The portion of the list to be displayed can be selected by the operator using the
vertical Ï Ð or horizontal Í Î scroll keys.
