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 71 and 72 on the GTERM-A board in GC80/85
Control unit.
To enable the function, S2-4 on the SCC boards has to be set to ON. Refer
DIP switch settings on SCC boards
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 start 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 return to fixed illuminated dots.
When this pendulum function input is activated, the external buzzer stop
input will not be available
