4.1 .1 Startu p
Start up the gyrocompass at least 5 hours before performing normal operation.
After the power switch is turned on, the gyrocompass system is started up at either hot start or cold
start depending on the condition of the gyrosphere.
If the gyro rotor is rotating at a high enough speed to detect the heading, hot start begins, however,
if it is rotating at a speed that is too low to detect the heading, cold start begins.

The rotating status of the gyro rotor is determined by monitoring the phase current.

(1) Hot start

Hot start begins if the value of the phase current immediately after turning on the power is 0.35 A
or less and follow-up of master compass, signal inpuUoutput, and indicator lamps are normal.

Phase curent

Time

(2) Cold start

Cold start begins if the value of the phase current immediately after turning on the power is higher
than 0.35 A. The stand-by state continues until the phase current drops and the rate of change in
the phase current drops below a specified level. Normal operation will start when these requirements
are met. During stand-by, functions of master compass automatic aligning and manual aligning
cannot be carried out. After about 2 hours, the heading indication settles and the gyrocompass is
ready for operation.

ENT key. Both AUTO and MANUAL blink. Then, with the up or down key select eitherAUTO or
MANUAL and press the ENT key.
IfAUTO is selected, the automatic ship's speed input becomes valid.
If MANUAL is selected, the tens digit of the ship's speed blinks, allowing for a value between OO to
99 kt to be entered for the ship's speed by manual.
Press the right or left arrow key to change the place of input and press the up or down arrow key
to change the numeric value.
After entering ship's speed press the ENT key. The input value blinks, signaling the need to validate
the change. Ifthe ENT key is pressed again, blinking stops and the input value is changed.

LAT SET

To select automatic or manual input, press the

ENT key. Both AUTO and MANUAL blink. Then, with the up or down key select eitherAUTO or
MANUAL and press the ENT key.
IfAUTO is selected, the automatic latitude input becomes valid.
If MANUAL is selected, the character N or S blinks allowing for a value between OO to 70 degrees
N or S to be entered for the ship's latitude by manual.
Press the right or left arrow key to change the place of input and press the up or down arrow key
to change the numeric value.
After entering the latitude press the ENT key. The input value blinks, signaling the need to validate
the change. If the ENT key is pressed again, blinking stops and the input value is changed.

Determine the true heading by calculating the value for speed-error-correction from the values of
speed and latitude.

True heading (deg) = (Compass heading) - (Value of speed-error-correction)

Value ofspeed error correctlon (deg) = ship's speed (kt) x cos (Compass heading)

If the ENT key is pressed when in this *"tate, the
"Ready" display appears showing standby for
automatic alignment.
Ifthe ENT key Is agam pressed the "Running" display appears showing that automatic alignment
is being carried out. (The mast~r compass starts automatic alignment.)

If automatic alignment finishes normally, the "Success" display appears. However if it finishes due
to a failure, the "Error' display appears. If a failure occurs, execute master compass alignment
manually.

4.7.4 Manual MaSter COmpass Alignment

If automatic master compass alignment cannot be executed, it is necessary to adjust the compass
heading to the container heading. There are relative value alignment and absolute value alignment
as the adjustment method.

>Please make zero degree the speed error correction value by setting ship's speed O kt
by using code "21 " when you execute this adjustment.

The error of the observation bearing that was measured by the gyrocompass is entered as the in put
value. (Input range : - 180 ' to + 180' )

Input value = (true reading tht'ough astronomical observation) - (compass reading)

Easterly : "-", Westerly : "+"
'
For example If compass readmg Is "050.0" and the true reading through astronomical observation
is "020.0", the input value is "- 30".

This method may be effective in case of sailing because the standard of absolute heading can be
not obtained .

(2) Absolute value alignment

By inputting present absolute heading the compass heading is adjusted to the value.
Input value = (true heading)
This method may be effective in the dock, because the standard of absolute heading can be obtained.

4.8 Procedures for Operating Repeater Com pass

4.8.1 Basic OperatiOn

The repeater compasses receive a serial signal from the master compass, and the compass cards
turn so as to indicate the true heading.

If power is supplied from the master compass, the compass cards turn and zero adjustment is car-
ried out. If this occurs, the run indicatorlamp blink. When the pointers align with zero on the com-
pass cards, the run indicator lamp stop blinking and remain lit.
If a heading signal is sent from the master compass using a serial signal, the compass cards turn
and display the same value as that displayed by the master compass.

COm pasS
It is possible to adjust null point by manually when null point detection failure is occurred.

The procedure is as follows:

This sectiOn describes the checkin9 procedure fOr error contents when an alarm is 9ener-
ated and countermeasures.

5.3.1 DISplay That Appears When an Alarm Is Generated

When an alarm is generated, the alarm lamp lights up and the buzzer stop key blinks with the
buzzersounds. Pressing the buzzer•stop key stops the buzz
The alarm lamp goes out if the alarm is reset, but continues to light up if the alarm continues.

The data display indicates the error code and

the cause ofthe alarm. (Thefigure on the right
shows an example.) GYRO l GYRO FAILED !

If there are two or more alarm causes, they are GYRO 2 Gl CODE= OIO

If the heading data is not obtained due to the cause of the alarm, the heading display indicates "---
.-" such as above figure. In this case, we recommend that the available heading sensor be selecf:ed
as the output heading.
When the heading sensor is changed from the present output heading to the available heading, 1:he
output heading value jumps to the selected heading value. Therefore, steering mode of autopilot
should be change to manual mode if output heading is changed.

The list of error codes is shown on the next page.

implement the operations and other work described in this chapter. However, if for some reason
the service department of Yokogawa Denshikiki Co., Ltd. permits you to perform these operations,
be sure to follow the instructions described in this chapter.

6.1 PrecautlOns during Installatlon

Exercise care with the following items when installing a gyrocompass.

6.1 .1 VibratiOn Measures

The floors on which the master compass and the horizontal stands are installed, and the walls on
which the remote unit, horizontal brackets, tilted brackets, course recorder, digital repeater compass,
etc. are installed, should be reinforced against vibrations from the hull.

6.1 .2 Parallelism Of Lubber's LineS

Install the master compass, repeater compasses for the horizontal stand and repeater compasses
for the horizontal bracket so that their lubber's lines are parallel with ship's fore-and-aft line. Since
the accuracy of the parallelism of these lines is the basis of heading measurement, adjust them to
within an accuracy of :!: 0.5 '.

6.1 .3 SerVice Area

Ensure that the dimensions ofthe running, operating and maintenance area ofthe master-compass
are as specified below.

6.2.1 PrecautlOns duMng RemOVal

(1) The gyrosphere should not be removed from the master compass until at least
1 .5 hours has elapsed since the power has been turned.

(2) Make sure that the surrounding area of the master compass is clean, there is
ample lighting and prepare all required equipment and tools before beginnir]g
work. To avoid damaging the nuts and bolts, be sure to use the correct tools
such as drivers and wrenches for each part.

(3) Be sure to do the following to ensure proper reinstallation ofthe gyrosphere:

• Provide mating marks to the required portions before disass

• Temporarily reinsertthe bolts into the correct holes.
• Place the disassembled parts in the correct orderon a piece
• Ifthemwires are to be disconnected, keep a record of the color of e
to ensure correct reconnection.

(4) Do not remove any part that does not need to be disassembled.

(5) Terminator CR - LF (fixed).

Transmission period
Can be set to O to 20000 ms in 100-ms increments. If the normal data transfer stops for a
period ten times the communication period setting, the gyrocompass system issues an alarm
for a communication port failure (time-out). If the communication period is set to zero, it does
not monitor the time-out.
