Trouble shooting
An alarm is initiated when an error arises in the control system. There are
two types of alarms:
•
•
Trouble shooting of the control system should always begin with
investigating whether any alarm has been initiated and if so which.
Certain alarms are automatically reset (Auto) after the cause of the error has
been remedied, while other alarms have to be manually (Man) reset.
If the control system is connected to a ModBus system, the alarms can be
read within the 10100 – 10139 range.
