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 enable 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 set to activate the function, the following
functions are obtained:
- The compass heading and repeaters change by 180° from
the 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.
