Sets the scaling of the rudder angle graph.
Settings: œ Vø
scale to show 9° to the left and to the right from the graph’s
centre. This setting provides a high-resolution recording of
small rudder movements and is useful for monitoring e.g.
the steering behaviour of an autopilot.
œ QRø
scale to show ± 45°. Standard setting for ± 45° steering
gears.
œ TMø
scale to show ± 70°. Standard setting for ± 70° steering
gears.
lcc
do not print rudder angle graph. Required setting if no rud-
der angle feedback unit is connected to the compass.
Sets the parameters for the analog rate of turn output.
`^rqflk Risk of ineffective manual ROT damping settings
The selected ROT damping time constant for the analogue ROT output in
the manual settings menu needs additional activation to become effec-
tive by means of a wire link installed at the master PCB TB2 19/20.
kçíÉ To make sure, that the ROT damping time constant setting for the ana-
logue ROT output becomes effective, check if the mandatory wire link
between the master PCB TB2 19/20 is correctly installed.
qfjb=`lkpqK=olq=L=qfjb=`lkpqK=clo=^k^ild=olq=lrqmrq
Sets the ROT damping time constant value for the analogue rate of turn
output. The larger the time constant, the less short-time fluctuations will
be present in the analogue rate of turn output voltage.
Value:
MKM=Ó=NMKM ëÉÅ
Typical values are generally between 2 to 4 sec. (only effec-
tive if wire link TB2 19/20 at the master PCB is installed)
kçíÉ Following IMO requirements, the ROT damping time constant value for
the analogue rate of turn output can be selected between 0.0 to 10.0 sec.
All selected values above 10.0 sec will not be accepted by the menu and
„ERR“ is displayed for showing that the selected value is not valid.
j^uK=s^irb=olq=L=j^ufjrj=s^irb=o^qb=lc=qrok
Sets the alarm threshold for the “Max. Rate of Turn exceeded” alarm.
Value:
