1 GENERAL INFORMATION
1.1 How to use this manual
This manual is intended as a reference guide for operating and correctly installing the RGC50 gyrocompass. The RGC50 is a compact gyrocompass, designed to enhance the navigation capabilities on small commercial, fishing vessels, and large pleasure yachts. A gyrocompass eliminates the inconvenience and limitations of magnetic compasses, and provides a variety of electrical outputs to supply accurate and consistent heading information to other navigation equipment. The capabilities and precision of the RGC50 will provide exceptional heading information to the navigation equipment installed on your vessel. Even if you are a previous owner of a gyrocompass, it is highly recommended that you review the instruction manual thoroughly before using the RGC50.
The basic RGC50 gyrocompass consists of:
RGC50 Master compass unit
Inverter unit, including power converter and control panel
Viewing screen (plastic piece that fits on top of master compass)
Several Simrad repeaters are available as options to the basic RGC50 gyrocompass:
OFF PRESENT TIME RUN
Figure 2-1 Gyrocompass control panel
Operating method with timer
The RGC50 has the capability of being turned on automatically at a specified time by a TIMER function within a 24-hour time frame period. 1. 2. 3. Set the master switch (1) to the TIMER position. Set the PRESENT TIME setting scale plate (2) to the present time. Set the ETD setting knob (3) to the scheduled ETD (estimated time of departure) on the PRESENT TIME setting scale plate (2). The red Timer running lamp (4) lights. By the above operations, the gyrocompass will be operative at the scheduled ETD. About four hours before scheduled ETD, the gyrocompass will be started. The green running lamp (5) lights. 4. When ETD comes, set master switch (1) to RUN position. The red Timer running lamp (4) goes out.
Assembly and installation
4 ASSEMBLY AND INSTALLATION
4.1 Preparation for installation
Electrical warnings The RGC50 is designed to be connected to 24 VDC power sources only. If 24V DC is not available on the vessel, it will be necessary to obtain an external voltage converter/inverter unit. Refer to the RGC50 specifications for details on the external voltage converter/inverter requirements. Transportation warnings The RGC50 must not be moved or transported without being properly protected. The sensitive element is packed in a carton box, and the final assembly must be done onboard the vessel. Never transport the RGC50 with the sensitive element assembled. For shipment in connection with service or overhaul, use the original packing.
Unpacking a new unit
The RGC50 is shipped with the sensitive element packed in a box separate from the master compass unit to protect the internal sensitive element from damage during shipment. It is required that the installing dealer perform the final assembly in accordance with procedure described in RGC50 Assembly instructions page 10, to install the internal sensitive element prior to operating the RGC50.
Standard equipment supplied A basic RGC50 is shipped with the following items:
RGC50 Master Compass unit (includes Master compass and Inverter unit)
Sensitive element (packed in a carton box) Spares kit (contains optional mounting bracket, spare fuses, spare bulbs) Shade plate
RGC50 Instruction manual RGC50 Assembly instructions After unpacking the RGC50, the following procedure must be performed to complete the assembly of the RGC50 gyro.
The assembly of the RGC50 is a delicate procedure, but it is not difficult if you follow the detailed instructions on the following pages. Perform this procedure in a location that is clean and dry. It is recommended that you have a small container tray available to place some of the small hardware that will be temporarily removed during this procedure. The following tools will be required for this assembly procedure: small Phillips head screw driver a pair of small pliers a large straight blade screw driver
Assembling 1. 2. 3. 4. Prepare a clean, dry and brightly lit area. Remove RGC50 master compass from the cardboard packing box. Place the Master compass on the bench in front of you so that control panel faces toward you. Set the Sensitive element in it's styrol packing container in a safe location on the bench. Do not remove the sensitive element from the carton box yet! Remove the 4 screws that attach the RGC50 Master compass top cover to the support rods, and save screws for reassembly. Carefully lift the cover and set aside for later re-assembly.
Store the carton box for later shipment of element for future overhaul. 15. Remove the two tie wraps securing the Horizontal ring. Be sure that the correct tie wraps are removed.
Do not turn the sensitive element upside down.
Do not touch the shims that are marked with tape at this time. These shims will be removed only after the RGC50 is installed on the vessel and must be available any time the RGC is transported! 16. 17. Remove the two mounting screws from the South horizontal axis, and set aside for later re-assembly. Carefully remove the South horizontal axis from the sensitive element, and place the axis on a clean surface. The South horizontal axis has a light coating of lubricant on it. This is normal. Do not wipe the lubricant off this axis. It is required for easy re-assembly. Rotate the sensitive element so that the North side (marked by a large N on the lower face of the sensitive element) is facing in the same direction as the compass card. This should put the five green flexible wires to your right and facing towards you.
TILTING VERTICAL RING
Lift the sensitive element by holding on the east and west side of the horizontal ring. Tilt the vertical ring as long as possible to one of the sides, and insert the north horizontal axis pin into the opening of the north side of the phantom ring. Then insert the south part of the horizontal ring into the phantom ring, and allow the element to rest on the base of the phantom ring. Verify that the five green flexible wires are located directly next to the vertical terminal strip that is attached to the South side of the phantom ring. (If it is not, then you have installed the sensitive element backwards! Refer to
steps 18, 19 and 20 to correctly orient the sensitive element.) 22. 23. Reinstall the South side horizontal axis pin carefully into the horizontal ring. Locate the North Horizontal axis bearing (removed in step 10). The North horizontal bearing is the larger of the two bearings. It will be inserted in step 26. Place the bearing on the table surface near the North side of the gyro, within easy reach during the next assembly steps. Locate the South horizontal axis bearing. (The smaller of the two bearings.) Place in on the table surface near the South side of the gyro, within easy reach during the next assembly steps. With your left hand, carefully grasp the sensitive element at the east side of the Horizontal ring, and lift it slightly (approximately 5mm). With your right hand, carefully insert the North Horizontal axis bearing into the opening in the phantom ring with the screw holes in the axis bearing oriented vertically. (This will also insure that the slot will clear the Allen screw that is installed into the horizontal axis pin). Slide the bearing into the opening while simultaneously inserting the horizontal axis pin into the axis bearing. When the bearing is seated fully into the phantom ring, the axis pin should also be inserted fully into the bearing. Carefully transfer hands so that your left hand is supporting the sensitive element. Using your right hand, insert the South horizontal axis bearing into the phantom ring opening. Carefully position the sensitive element so the south horizontal pin is inserted into the axis bearing, as you press the axis bearing into the phantom ring opening. It may be necessary to slide the sensitive element assembly over towards the South axis in order to seat the axis into the axis bearing. Be careful to align the screw holes for the axis bearing with the screw holes in the phantom ring. At this point, the sensitive element should pivot freely in both axis directions. If your feel any binding, it means that one of the bearings is not installed correctly, or the axis pins are not seated into the axis bearings. If necessary, repeat step 26 and 27 until the sensitive element pivots in both axis directions without any binding. Rotate the North horizontal axis bearing until the screw holes are aligned with the screw holes in the phantom ring.
The inverter unit consists of a switch panel and an Inverter board. The start switch, time setter, indicator lamps, a fuse, and illumination controller of the master compass are arranged on the switch panel. Operations are performed entirely on the surface. PCB is incorporated and can be replaced by disconnecting the connector. Its consist of timer, inverter and 1 ~ 3 phase converter circuit. A filter to eliminate noise is built in the Inverter unit.
6.1 Master compass
Adjusting the torsion of the suspension wire
1. Remove the square damping weights on the west side of the rotor case. Attach the round weights and put back the nuts and washers. Mount a level on the level mounting base of the horizontal ring. Apply a wood block between the bottom of the sensitive element and the phantom ring and adjust it so that air bubbles in the levels of the horizontal and vertical rings come to the middle. Turn the rotor case to the left and right until it reaches the stoppers and leave it as it is. If there is no torsion in the suspension wire, the marked-off lines of the rotor case and vertical ring agree with each other. If there is a large torsion, loosen the two flat head screws on the suspension wire and turn the support fitting on the suspension wire to make the marked-off line coincident. Then, tighten the flat head screws and minutely adjust the marked-off lines with the tangent screw. After tightening, check again.
Vertical balance (east-west direction) 1. Manually hold the bottom of the sensitive element and bring the air bubbles to the middle of the horizontal ring level and rotor case. Bring the marked-off line of the rotor case to be roughly coincident with that of the vertical ring Tilt the vertical ring toward the south side. At this time, the marked-off lines of the rotor case and the vertical ring must remain coincident. a. If the west side is heavy (the marked-off line of the rotor case gets displaced to the right), reduce the adjusting weights (round) on the west side of the rotor case by equal amounts. Or add two equal weights to the adjusting weights (round) on the east side.
Cleaning and lubricating method for the gimbal ring bearing
North-side bearing This bearing is united with the damper housing. After cleaning, fill the bearing with 0.7cc of the damper oil (KF96, 100,000CS). The damper is effective if the sensitive element stops after five times swinging or so when it is assembled and swung. South-side bearing Remove the retainer and pull the bearing out. This bearing is of shield type and replace with new one when wrong friction condition.
Disassembling horizontal ring
3. 4. 5.
Remove the acryl cover of the west side flexible wire. Carefully pull out five flexible wire pin on the horizontal ring from the connector. Remove one of the mounting screws of the flexible wire support fitting and fix it aslant with another screw. Then remove two lead wires (orange/green) connected to the liquid ballistic, from the back side.
6. 7. 8.
Remove the round lock nut of the east-side horizontal axis. Remove the mounting screws of the east and west side bearing housings and pull them out. Remove the mounting screws of the east side horizontal axis and pull it out. (Remain the west side axis.) Pull the horizontal ring out while keeping the vertical ring aslant.
Disassembling liquid ballistic
Take out the air tube of the liquid ballistic from the liquid ballistic container. Loosen the screws of the liquid ballistic frame on the east and west sides and take the liquid ballistic out downward together with the mounting block. Care should be taken not to damage the follow up coil in such a way as covering it with a vinyl pouch. Do not remove the liquid ballistic container, the pipe and the follow up coil from the mounting block. When these positions are moved, the time has to be wasted for the cross alignment adjustment. The liquid of the ballistic is Galden HS, and 4.6cc is used. Clean the inside of the liquid ballistic pipe with air below and not to wash with benzine, etc.
(The liquid does not need to be exchanged when the flow condition, the volume and the color are normal.)
Disassembling vertical ring
1. 2. 3.
Measure the clearance between the inner ring of the vertical ring lower axis and the rotor. (0.35 mm ~ 0.4mm) Pull out both the upper and lower connectors on top of the vertical ring. Remove the vertical flexible ass'y, and mount JIG C (refer page 36) on the connector place.
Remove the lower mounting screws of the flexible wire mounting plate and then remove the L shape fitting. Pay attention not to cut the flexible wire. Insert the shim about 0.6 mm thick to the clearance between the rotor case lower side and the vertical rotor case lower side and the vertical ring to give bending to the suspension wire. This should protect the suspension wire when removing it.
Remove the mounting screws of the clamp disk plate on the top of the suspension wire, and loosen the tangent screw to remove the clamp disk and the adjustment arm. Remove the mounting screws at the bottom of the suspension wire. Hold the rotor with one hand to avoid twisting the suspension wire. Pull the top of the suspension wire with hand (pull it up with fingers) to take out the suspension wire axis. Then take out the suspension wire through the slot in the vertical ring north side. Insert Jig A (refer page 35) for upper vertical axis. Remove the fitting plate. Length of the fitting plate mounting screw is 10mm. Be sure to use the same screw when reassembling. Bring the vertical ring down with its north side below, and loosen the housing case mounting screws of the lower bearing to take out the housing case. Pay attention at this time on the numbers of the adjusting shim.
Loosen the mounting screws of the vertical lower axis to pull the axis out. Pay attention not to give damage on the bearing fitting surface of the axis. Remove Jig A that was inserted in point 9. Take the rotor case out of the vertical ring from south side. Remove the fixing retainer of the upper bearing housing on the vertical ring to remove the housing case.
13. 14. 15.
Cleaning and lubricating bearing of horizontal and vertical axes Horizontal bearing
1. Remove the housing cover mounting screws to take the bearing out. Pay attention on the numbers of the shim. 2. Clean the bearing according to the precautions described in page 35.
1. Remove each retainer of the upper and lower housings to take out the collar and bearing. 2. Clean the bearings according to the precautions described in page 35.
Lubrication for bearing
The bearing should be housed in the housing case with the side of better rotation upward when the bearing is inserted to the erected pincette upside down and turned slightly by hand. Replace the bearing of poor rotation with a new one. It is desirable to use the bearing of the best rotation for the vertical axis. The best lubrication for the horizontal and vertical bearings is as follows: Put 3-4 drops of DTE oil into the bearing and gently turn the bearing.
It is desirable to confirm the vibration state of the rotor running before disassembling.
Install the bearings into the south and north side case with the surface having a stamp on the outer race outward. Tighten the fixing screws of the south and north side of the inner bearing. Install the rotor into the south side case. Install the north side case and tighten the six mounting screws. Ensure that you mount the case in the correct direction. The followings are common to the north and south without the special notice.
4. 5. 6.
Install the bearing fixing bush (with the notch downward). Install the guide ring into the housing case (with the notch outward and upward). Install the oil wicks (three kinds).
Remove the powder on the new oil wicks by air blow. Install the oil wicks carefully because the life of the rotor bearing is affected by their installed condition.
a) Place the oil wick - 1 (P/N 102216090) with its tip at the top.
110 mm 6 mm
t = 5 mm
b) Install the oil wick - 2 (P/N 102216090) so that its tip is inserted to the notch of the guide ring and lie along the axis. (Remember the condition when disassembling.)
110 mm t = 2 mm 6 mm
c) Insert the oil wick - 3 (P/N 102216100) to the gap at the bottom of the busk case.
11 mm 5 mm t = 1 mm
d) Pour 4 cc of DTE oil light at the one side of the wick. Pour the oil over the wick uniformly using an injector, etc. 7. 8. Install the south side cover. Place the spring in the north side and install the cover. Be careful not to damage the follow-up coil on the south side.
a) After assembling, make sure the rotor has a spring action with swinging the rotor rather strongly in the direction of north and south while keeping the rotor horizontal by hand. b) Make sure the vibration of the rotor when the power is supplied to the rotor only. (It is acceptable to have the same order vibration as before disassembling.) The vibration less than 0.5 micron is desirable at the top of the N/S side rotor axis when measuring with the vibration meter. c) Stop the rotor with the opposite phase connection of the power supply.
Assembling the vertical ring
Install the housing case at the top of the vertical ring and fix with the retainer. Place the rotor with the north side upward. Insert the vertical ring and fix the upper portion (Jig-A) and the lower portion (Jig-B) using the vertical ring assembling jigs. Mount the fixing plate for the rotor and the vertical ring. (The mounting screws are two of 3 mm - 12mm length, and one of 3 mm - 10 mm length.) Mount the balance weight on the north side of the rotor. Pull out the lower jig and mount the lower axis. Then mount the housing case of the lower bearing. (Be careful of the clearance adjusting shim.) Erect the vertical ring assembly. Pull out the upper jig and mount the suspension wire assembly. Tighten the mounting screws of the suspension wire while pushing the rotor slightly with hand. Tightening the screws with pushing the vertical ring strongly may cause damage of the suspension wire. Mount the clamp disk and the arm at the top of the suspension and tighten the tangent screw slightly. Measure the clearance of the lower axis to be 0.35mm (hardly) and 0.40 mm (softly). Be sure the rotor moves slightly up and down with this clearance. Mount the flexible wire assembly of the suspension wire section with (Jig C). Be careful not to damage the flexible wire.
When the movement is more than five minutes observed on the boble level, do as followes: 3. When the N side of the spinning axis tilts up, loosen the mounting screws of the 2ry pick up coil to move it in the east direction by beating slightly with a screwdriver, and tighten the screw. When the S side tilts up, move the 2ry coil in the west direction. Perform the test again (2) to check the level movement.
Large aberration of the pick up coil to the above each axis may cause error of the gyro when the ship is rolling.
Necessary items should be recorded referring to the check sheet in the separated table.

Handling of Electrostatic-Sensitive Devices
Observe Precautions for handling Electrostatic Devices
Caution Handling of Electrostatic-Sensitive Devices
Certain semiconductor devices used in the equipment are liable to damage due to static voltages. Observe the following precautions when handling these devices in their unterminated state, or sub-units containing these devices: Persons removing sub-units from any equipment using electrostatic sensitive devices must be earthed by a wrist strap via a 1M resistor to a suitable discharge reference point within the equipment. Soldering irons used during any repairs must be low voltage types with earthed tips and isolated from the Mains voltage by a double insulated transformer. Care should be taken soldering any point that may have a charge stored. Outer clothing worn must be unable to generate static charges. Printed Circuit Boards (PCBs) fitted with electrostatic sensitive devices must be stored and transported in appropriate anti-static bags/containers.

It is possible to configure the Aux port on the SeaKing Sonar for input of RS232 / RS485 serial data from an MDL (or compatible) Gyro. It may be possible to power the Gyro from the Sonar Aux Port but first check that the Power ranges are the same. The 24VDC power that is applied to the Sonar Main port is linked directly through to the Aux port. If the Gyro power requirements are 6 - 16VDC then DO NOT power directly from the Sonar AUX Port as this may damage the Gyro.
Either install an in-line DC adapter to the Sonar AUX Port or power the Gyro from an external PSU.
Note: It is recommended, whenever possible, that RS485 be used for the Gyro to Sonar Aux Port telemetry link. Using RS485 (instead of RS232) avoids breaking the power isolation in the SeaKing head.

CONFIGURING SEAKING COMMS BOARD FOR AUX SERIAL I/O
1. Before opening the Sonar head to access the Comms board jumpers, using the 'Seanet Setup' utility program configure the following check box settings. These are needed to enable the 'Aux' port; a) b) Open the Seanet Setup program and ensure that Node 2 is detected in the table. Click on the Action column for Node 2 and then select Setup, as shown
In the Sonar Setup panel, ensure that the Has Aux or Compass check box is enabled.
N.B. If the AuxComm 1 Sec Rate check box is disabled, the Sonar will try to send up all data collected through its auxiliary port. Please be aware that if the quantity and rate of this data is too great then the interface may hang up.

From here press the Baud Rates Button.
Check Baud rates on Async 1 (AUX) match the device output (default Digiquartz output is 9600 baud).
2. Now change the jumper settings on the Comms board inside the Head. In the SeaKing head, this must be a COMDV3/FV3, COMGV3/V5 or a COMV5 Mod-A board. The jumpers should be set as follows - refer to the option that suits your configuration.
<< See the 4 options that now follow >>
Ensure that the sonar Aux port is fitted with a Water Block connector.

N.B. The Digiquartz data will be logged along with Sonar data and will be displayed during later playback of the log file.
REGIONAL SETTINGS and AUX data
It has been noted that Windows regional settings can prevent the flow of AUX data through the system. If the Aux device is connected correctly and operating but no data is displayed on the screen then the Regional settings may be preventing Seanet Pro from processing the data. In the Windows Control Panel open REGIONAL & LANGUAGE OPTIONS. Set the drop down list to English(United Kingdom) Press OK for the changes to take effect. Restart the Seanet Pro MiniKing software and check whether the AUX data is now displayed. If you wish to continue using your local settings then open REGIONAL & LANGUAGE OPTIONS. Set the region to the desired setting. Now press the Customize button and ensure that the DECIMAL SYMBOL is set to a.
