System Select

The "System select" (Sys. Sel.) input signal of the J50 can be used
to alternate between the boat's own steering and the autopilot
system from an external system selector (refer to IMO resolution
MSC. 64 sec. 4). A ground on TB14 Sys. Sel. will force the
system into Disengage mode. The autopilot will be disconnected
from the vessel's steering system and show "Disengaged" on the
display (on the FU50, no mode indicators will be lit). When the
"Sys. Sel." input line is re-opened, the autopilot will go to AUTO
mode. For wheelmark installation (Master operation = Yes, ref.
page 49) the master control unit will be active.
