10.3 Finding and rectifying faults
10.3.1 Fault states
With the aid of the event memory and the relevant event code display (can be called up from the SD memory card), it is possi-
ble to localize the error in the event of a fault. The table below lists the event codes for 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 .
