6.1 Gyro 1 fails
If the automatic switch--over function G/G is selected (see manual for Operator Unit), the
system (Distribution Unit) switches--over immediately to Gyro 2.
Is this function not selected, a manual switch--over to Gyro 2 has to be carried out.
The message "Switched to GY2" is displayed only, if the automatic switch--over function is
selected.
An alarm is generated acoustical and optical and has to be acknowledged (see manual for
Operator Unit).
This error message "Gyro 1 Failure" can be detached from the Distribution Unit and for-
warded to external alarm devices (detached from the Change over Box too -- if connected).
An automatically switch--over to Magnetic Sonde is only possible if both Gyros fail.

Error performance
After a RESET of the complete system and Gyro 1 still fails, the
Gyro 2 is designated as Gyro (the numerical indication is no
longer displayed).
After a repair is to pay attention that the repaired Gyro is integra-
ted into the system with the lowest CAN bus address again --
otherwise it will not be identified as Gyro 1.
