Accessing the Alarms Setup Page
From the home screen or the main run-screen, in monitor-mode or run-mode, press the setup button, then select the alarms icon.
This takes you to the alarms setup page.
From here you can:
Types of Alarm
The controller is able to detect the following alarms:
Temperature-Tolerance, Power-Tolerance and Cold-Thermocouple alarms are controlled by values set by a Supervisor.
The Alarm Setup Panel displays a list of zones, identified by number and name (if configured).
The current value for each alarm condition is displayed for each zone in a table.
Here, zone 7 will trigger the temperature-tolerance alarm whenever it's temperature strays more than 5 degrees above or below the setpoint.
With a 12% power-tolerance, the zone will trigger an alarm if it's average power consumption for it's heater is 12% greater or less than the average power consumption for all of the cavities. You cannot set a power-tolerance for manifolds. The average is taken from the last 60 seconds, on a rolling-average basis.
A 15 minute cold-thermocouple detection time means that the controller expects the zone to reach setpoint within 15 minutes of starting up.
Changes to the temperature-tolerance, power-tolerance or cold-thermocouple alarm limits are made through the Edit Alarm dialog.
This dialog has it's own status-bar, which instructs the user what to do.
Using the Edit Alarm dialog is easy:
The controller can take various actions when an alarm condition is triggered:
To make changes to the Alarm Actions page, you must be logged in as a Supervisor.
This zone is out of temperature-tolerance (over setpoint), so it's temperature is coloured red. If a temperature is coloured blue, it is under setpoint.
Temperatures displayed in green are in-tolerance.
The zone is also out of power-tolerance (over); it's power level is coloured red. This zone needs more power than expected in order to maintain setpoint. If the zone needed less power than expected it would be coloured blue. Zones which are in power-tolerance are coloured yellow.
These colourings hold true so long as the zone has a configured value in it's Alarm Setup Panel (i.e.: it is not set to "off"), even if the Alarm Action is set to "ignore".
You can select alarms from the list to find out more:
Alarm Relay will be toggled. Alarms actions set to "Alarm" will be removed from the Alarm Warning Dialog when the alarm condition no longer exists. When all alarms have been removed from the list, the Alarm Warning Dialog will be dismissed automatically, the Alarm relay will be toggled and the controller will resume normal operation.
However, if an alarm action is set to "Rest" or "Shutdown", the Alarm Warning Dialog will remain on-screen. The alarm conditions for these cases are not removed from the list and the controller will require user intervention in order to resume normal operation.
All alarm conditions are logged so you can see which alarms occured and when they were triggered:
You can check whether the Alarm Relay has been toggled from the status bar. An orange alarm-bell icon is displayed whenever there is an alarm and the alarm relay has been set to stop the machine from cycling:
