....
Information.
In case of NFU rudder control
(Bang--Bang control).
Test run required.
Functional check.
Checks the RUD SLACK setting. The switch pulses / min for
the steering gear are counted and indicated.
A reduction in RUD SLACK increases rudder activity and the-
reby the accuracy of the control.
Attention: Rudder Hunting occurs when RUD SLACK
selection is too low.

36 tiller .... Information.
When the external signal feed for
the selected tiller is to be chek-
ked.
Functional check of the tiller (FU / NFU)
Indicates a coded rudder value, depending on the set rudder
scaling (+ for starboard, -- for port).
Offset and ccale adjustment of the FU tiller 1/10

.
NFU tiller mid--position --700, STBD approx. +672, PORT
--672.

TRACK operating mode.
Special service setting for navi-
gation receivers with XTE tele-
gram transmission.
The track controller reacts too
slowly to a strong drift.
The integral component of the track controller can be increa-
sed.
The increase can be carried out in 2 steps.
Aim: the track error is to be better compensated for in case of
stronger drift.
Disadvantage: Longer settling processes can be expected in
case of abrupt disturbance changes.
Attention: The selected setting is deleted after a POWER
DOWN. The DEFAULT value is effective after a
renewed putting into operation.

TRACK operating mode.
Special service setting for navi-
gation receivers with XTE tele-
gram transmission.
Transmission errors from the na-
vigation receiver.
If track error jumps occur -- caused by the navigation receiver --
then xtefi can be set to 1.
The transmission errors are reduced by switching on an elec-
tronic filter.
Disadvantage: The entire track control is less accurate.
Attention: The selected setting is deleted after a POWER
DOWN. The DEFAULT value is effective after a
renewed putting into operation.

HEADING CONTROL operating
mode.
Heading deviations, that can only
be corrected after a longer period
of time, occur during a test run.
The heading controller should compensate for DRIFT EF-
FECTS within an adequate time.
The time can be shortened or lengthened with this setting (inte-
gral component of the controller is changed).
0 = fast/250 = slow
Attention: The selected setting is deleted after a POWER
DOWN. The DEFAULT value is effective after a
renewed putting into operation.
