30 988-12721-001
Power supply
The GC80/85 Double Control unit is powered from the two GC80/85
Expanded gyro systems and does not need to be connected to any
additional external power source.
6.4 Grounding the unit
The Double Control unit should have a proper ground connection from the
unit’s ground terminal (
A
).
The wires should be as short as possible and have a cross section of at least
AWG13 (2.5 mm 2 ).
DOUBLE SYSTEM CONTROLLER UNIT
6.5 DIP switch and jumper settings
The GC80 and GC85 Double System Controller units include several DIP
switches and jumpers. With the exception of 2 switches on the SCC board
in the control unit, no switches have to be set when installing the system.
These 2 switches are set to configure the control unit to match the type of
gyro system (GC80 or GC85).
Note! All DIP switch settings are read when the system is started. Any changes made
while the system is running will therefore not take effect until the system is
restarted.
For a complete list of DIP switch settings, refer to “DIP SWITCH SETTINGS”,
page 56.
Activating the GC80 or GC85 Double System
Controller unit
When the gyro system is shipped from factory, all DIP switches in the
control unit are set as a standard GC80 system.
Before the system is started, the switch settings described below have to
be changed to match a GC85 system.
DIP switch NO.2 on S1 on the SCC board identifies the gyro as a GC80 or
GC85 system.
