Simrad GC80/GC85 Compact Gyro Compass
2 If the tilt angle is incorrect, weight disks must be adjusted by moving weights from one side to the other. After adjustments, wait for 2 minutes before the tilt angle verification is repeated.
Caution The sensitive element must have equal number of weight disks on both weight points on the tilting side (north and south side)!
3 Carefully rotate the Horizontal ring at least one complete rotation. Verify that all movable parts will rotate without making any contact with mechanical or electrical components.
Parameter updates
When a sensitive element is replaced, parameters for the new element have to be loaded into the GC80 Control unit before the gyro compass is started. This is done from the Extension menu as described below.
1 Enter the Extension menu by pressing and holding the SET button and the ACK/ENT buttons simultaneously for at least 3 seconds.
Main category A-1 will be displayed.
2 Press the SET button to enter the sub-category loop. Subcategory 1.1.U and its parameter values will be displayed.
3 Use the arrow buttons to increase or decrease the parameter value until the value is according to the labelling for the new sensitive element.
4 Confirm the entry by pressing the ACK/ENT button. The display will return to sub-category 1.1.U, and the data will be transferred to the gyro immediately.
5 Press the DISP button again to select sub-category 1.6.t, and use the arrow buttons to increase or decrease the parameter value until the value corresponds with the parameter for the new sensitive element. Confirm the entry by pressing the ACK/ENT button.
