10.3 Finding and rectifying faults
10.3.1 Fault states
In the event of a fault the fault profile can be localised using the event memory and the corresponding event code display,
which is obtained using the segment display on the AMB 32 (switch position
E ). The following table lists the event codes of
possible fault states and how to rectify them. A list of all the event codes is provided in Sec. 8.5.4.3.
Notice
Multiple codes : If there are multiple events for any given event group, the display readings are added together.
Example: Display 012 = event code 004 and 008 .
