Safety Instructions

CAUTION
Risk of mercury contamination
The gyrosphere type 3 and the gyrosphere container mod. 10/3 and
mod. 10/4 are designed for mercury free operation. Any usage of mer-
cury will severely contaminate the gyrosphere type 3 / gyrosphere con-
tainer mod. 10/3.
Never use mercury with the gyrosphere type 3 and the gyrosphere con-
tainer mod. 10/3.
In case of usage of mercury by mistake, the contaminated equipment
must not be used and all safety instructions of the Sperry Marine Mer-
cury Handling Procedure 026150-0000-000 must be followed accordingly.
CAUTION
Risk of defective gyrosphere caused by “GYRO FAILURE”
Should a “GYRO FAILURE” alarm occur during power-up, the compass
is not working properly.
De-energize the system and visually check the connections to the gyro-
sphere, the follow-up step motor and the shaft encoder.
If the failure reoccurs when the compass is powered-up again, the instal-
lation has not been carried out correctly or the gyrosphere is defective
and must be replaced.
CAUTION
Risk of damage through aggressive cleaning agents
Do not clean the compass with organic solvents, acetone or any other
substance which could damage or discolour plastic.
Only use water and soap or a mild detergent to clean the compass.
CAUTION
Risk of damage through overheating
A polluted or clogged air inlet grill located at the back side of the compass
housing will decrease the functionality of the cooling fan and cause over-
heating of the gyrocompass.
Always maintain the required distances around the compass housing to
enable sufficient air supply and full cooling fan functionality.
Make sure to regularly clean the air inlet grill from dust and dirt and check
the cooling fan functionality to avoid overheating.
CAUTION
Risk of damage through rotating masses
After power-down of the compass system, the gyroscopes need at least
45 minutes to stop rotating. Opening the container or draining off the
supporting fluid during rotating will damage the gyrosphere.
Wait at least 45 minutes after power-down of the compass system and
make sure, that the gyroscopes have stopped rotating before opening the
container or draining off the supporting fluid.
CAUTION
Risk of damage through misusage
Scheduled maintenance or service work on the gyrosphere is to be car-
ried out by authorized service personnel only.
CAUTION
Risk of damage through unauthorized service
Any service and installation work on the gyrosphere is to be carried out
by authorized service personnel only.
Never undertake service or installation work if unskilled for the certain
procedure.
