Visio-3 Priority-1 Screen
When the Visio-3 is initially setup it is important that the correct type of homepage is selected because it may compromise the quality of a product or may compromise the health & safety of personnel depending on the Visio-3 application.
The alarm handling for a Priority-1 screen shown below is different for that of the Priority 1-2-3 screen (Shown on the right) and it is for this reason that they will be explained separately.
It can be seen below that 'Pressure' is the critical parameter and the alarm handling is slightly different to the Temperature & Rel-humidity. The screen sequence to the right show the alarm handling for the Pressure and the sequence on the left shows the alarm handling for the Temperature & Rel-humidity.
This parameter is deemed to be critical in a Priority-1 configured homepage.
The alarm feature displays an alarm message screen when in an alarm state.
When the Pressure deviates from setpoint by a pre-set amount, the homepage changes colour from green to amber thus indicating a warning.
The alarm buzzer will activate every 5 mins for 10 secs.
If the Pressure deviates further from the setpoint, the homepage will change colour from amber to red thus indicating an alarm. After a 7 sec delay the alarm message screen will appear, remain for 14 secs and subsequently alternate with the homepage for as long as the alarm condition exists.
The buzzer will remain activated until muted or until the alarm condition disappears.
These parameters are deemed non-critical in a Priority-1 configured homepage.The alarm features differ from the Pressure in that the Visio-3 does not display an alarm message screen when in an alarm state.
When either parameter deviates from setpoint by a pre-set amount, the associated bar changes colour from green to amber thus indicating a warning.
The alarm buzzer will activate every 5 mins for 10 secs.
If the parameter deviates further from the setpoint, the bar will change colour from amber to red thus indicating an alarm. The buzzer will remain active until muted or until the alarm condition disappears.

Visio-3 Priority-1-2-3 Screen
All 3 parameters are deemed critical in a Priority-1-2-3 configured homepage.
This alarm feature displays an alarm message screen when any of the parameters are in an alarm state. The example here shows what happens when the Temperature deviates from setpoint.
When the Temperature deviates from setpoint by a pre-set amount, the bar changes colour from green to amber thus indicating a warning.
The alarm buzzer will activate every 5 mins for 10 secs.
If the Temperature deviates further from the setpoint, the bar will change colour from amber to red thus indicating an alarm. After a 7 sec delay the alarm message screen will appear and subsequently alternate with the homepage for as long as the alarm condition exists.
The buzzer will remain activated until muted or until the alarm condition disappears.
