1.8 Rate-of-Turn Gyro DS-670 (option)
The rate-of-turn gyro must be installed, in a location with minimal vibration, so that the
sensor in-side the unit is level to within 1 degree. (There is no designation for orienta-
tion of the unit.) Select the location considering that the cable for connection with the
distributor is 5 m.
Note: When installing the rate-of-turn gyro, wear the earth strap to prevent the elec-
trification.
Use the four stud bolts, flat washers, spring washers and eight adjust nuts to fix the
unit. See the outline drawing at the back of this manual.
Use the XH connector (supplied with DS-670) to connect cables.
Leveling adjustment
This adjustment must be performed while the ship is in dry-dock where it has no heel-
ing and trimming inclinations.
Place a T-type level meter on top of the sensor to measure longitudinal and transverse
inclination. To level the sensor, turn the adjust bolts.
