FX-350 Series Installation and Operation Manual
45
If the device or circuit returns to normal, the system normal message will be re-displayed. If multiple pre-alarms or
alarm verification sequences are active at the same time only the first is displayed. Pressing the INFO button while
the pre-alarm or verification message is active will display additional information on the circuit or device as
described under queue display mode.
Queue Display Mode
Active inputs are all combined together and displayed in one queue with alarm, supervisory, trouble, or monitor and
having priority in the same sequence as they are listed with alarm as the highest priority. In addition any internal
non-fatal troubles which will cause the common trouble sequence to be activated will also result in a specific
message to be placed in the queue with trouble level priority. The message is displayed in the following format:
Pressing ‘INFO’ Key
Where:
• the first line shows the process type and the input or output designation
• the second line shows the active status or the trouble status depending on the circuit type and the location of the
message in the queue along with the total number of messages in the queue
• pressing the INFO key provides some additional information
• the first line shows the process type
• the second line shows the loop# where the device is connected and the device address
For internal troubles the 2 line message is an internally formatted message which identifies the trouble along with
any additional information which can help in diagnostics. Whenever there are active inputs in any of the queues the
display will automatically display the oldest un-viewed event in the highest priority queue. The queue priority is a
follows: alarm (highest), supervisory, trouble, monitor (lowest). During queue display mode, the messages in the
queue can be scrolled using the UP and DOWN key. For non-latching inputs (monitors, non-latching supervisory,
non-latching troubles) the message is removed from the queue when the circuit is restored. Latching input types
will only be removed at system reset.
