Operating condition 2 “Heater failure”
This condition is output when the heater (
45
C) has failed.
Compass operation is not restricted if the temperature is more than 45
C (see also “fan
failure”.
A temperature drop down below 45
C leads to an error message “Error” and the heading
information will not longer displayed ( as well as the heading information to the
connected heading receivers).
To prevent the supporting liquid from cooling further, it is recommended that to do the

Operating condition 3 “Supporting liquid > 60
C.”
This condition is output when the temperature of the supporting liquid is higher than
60
C.
To prevent the temperature from rising further, it is recommended that you do the
following:
-- Open the door on the compass
-- If necessary cool the outer sphere using an external fan.
-- Check the ambient temperature. If the ambient temperature is higher than
60
C steps should be taken to cool it down.
These measures should be continued until condition 3 stops.
If condition 3 is displayed in combination with condition 1, the fan must be
replaced at the earliest opportunity.
