Intervention messages are 1-part or 2-part messages. Two-part messages consist of two 8-character message parts that alternate. The message types are FID1 messages, attention messages, routine messages, FID2 messages, FID3 messages, and FID4 messages. A brief description of each message follows:

vFID1 Messages

The device generates a FID1 message when a hardware failure occurs within the device. This error condition message has priority over all other types of messages, and persists until corrected. Maintenance personnel uses the FID code to identify the failing units within the device. (Menu selections may overwrite FID messages temporarily.) Messages are in a bold font.

The format of these messages is ‘FID1 xy’. ‘FID1’ indicates to the operator that a failure occurred, and ‘xy’ is the replaceable portion of the device. Figure 7 on page 18 shows an example of FID1 C6, which indicates that the machine reel motor has a fault.
