Removal of the Gyrosphere Container at Low Ambient Temperatures
At ambient temperatures below 0 °C when the gyrocompass is not in operation, and
below -10 °C when the gyrocompass is in operation, the gyrosphere container is to
be removed from the compass housing and stored at a place where the ambient
temperature will not fall below 0 °C.
If no storage place is available where the ambient temperature will not fall below 0 °C,
the gyrosphere is to be removed from the gyrosphere container to prevent damage
caused by frozen supporting fluid. The gyrosphere may be removed only by person-
nel of a C. PLATH-authorized service station.
1)
De-energize the gyrocompass system.
2)
Wait at least 45 minutes for the gyro-
scopes to stop rotating.
3)
Unscrew the retaining screws of the com-
pass housing door and take the door off
the housing.
4)
Disconnect the grounding strap between
door and housing. If the control and dis-
play unit is mounted in the door, unplug
the unit's connector from the masterboard
(plug connector J3).
5)
Place the door aside.
