Alarm List
The JCB Digital Control Panel Controller has an alarm list, which stores the details of both active and inactive alarms. There are different classes of alarms programmed within the JCB Digital Control Panel, some critical alarms such as ‘Emergency Stop’ will cause the set to shutdown, sound an audible alarm and will prevent restart, until the issue has been resolved and the alarm cleared from the list.
