5.2 ECU alarms
The ECU generates alarms which are indicated in different ways depending on the equipment configuration:
• as four-digit code on a PIM
• as alarm text on a display
• as four-digit code on a dialog PC
The four-digit code consists of one letter and three figures:
• The letter encodes when the fault occurred the last time:
A = currently present
B = within the last operating hour
C = one to four operating hours ago
D = four to twelve operating hours ago
Alarms that occurred more than twelve hours ago are deleted automatically.
• The three figures encode the fault itself as listed in the table below.
Alarms can also be caused by defective sensors / actuators. If troubleshooting in accordance with the following
table is not successful, contact Service to have the sensors / actuators checked and, if required, replaced.
