Simrad GC80/GC85 Compact Gyro Compass

3.6 Pendulum function

GC80/85 software includes a pendulum function that enables the heading to be changed by 180°.

The heading change is activated by closing a potential free contact connected between TB1, pin 25 and 26 in GC80/85 control unit.

Note! To identify the function, S2-4 on the ICIF board has to be set to

ON. Refer DIP switch settings on ICIF board, page 91 onwards.

When the switch is activated, the following actions are performed:

- The compass heading and repeaters start to change towards the new 180° shifted heading

- An acoustic alarm sounds 5 times

- The dots in the indicator field in the display starts flashing.

These will remain flashing for as long as the pendulum function is active.

Normal compass operation is resumed by opening the closed potential free contact. The function is indicated by the same acoustic alarm, and the flashing dots returns to fixed illuminated dots.
