Page 9: Safety Instructions
SRD 500 A 056361/F Safety Instructions Safety Notice Conventions The following safety notice conventions apply throughout this manual: A Danger notice contains an operating or main- DANGER tenance procedure, practice, condition, state- ment, etc., which, if not strictly observed, will result in injury or death of personnel.
Page 10: General Safety Information For The Operator
The NAVIKNOT electronics unit and CDU unit are generally not field-ser- viceable on the component level. Defective units must be returned to Sperry Marine for exchange. Any service work on the electronics unit or CDU is to be carried out by authorized service personnel only.
Page 11 The design and implementation of modifications to the hull which might be required to achieve satisfactory performance of the speed log are beyond the scope of Sperry Marine's expertise or responsibility and are, therefore, the responsibility of the shipyard or shipowner.
Page 12 Sperry Marine Service: Note In case of service refer to www.sperrymarine.com/offices for a list of all Sperry Marine Offices and Service Agents worldwide.
Page 13: General Safety Information For Service Personnel
As a minimum, ensure that the atmosphere in the confined space is safe and breathable. Sperry Marine recommends that a competent person test the atmosphere for oxygen deficiency, combustible gases, hydro- gen sulfide, and other hazardous gases that are reasonable to expect in that area.
Page 14 056361/F SRD 500 A WARNING Risk of electrical shock Avoid installing the SRD 500 Doppler EU in hazardous areas. If it is unavoidable to install the unit in a hazardous area, secure the SRD 500 Doppler EU inside an explosion proof housing and the intercon- necting cables inside an explosion proof conduit.
Page 15 SRD 500 A 056361/F CAUTION Damage to the transducer function caused by cabling changes) Cutting or shortening of the transducer cable or connecting new cables with existing old cabling will lead to damage or malfunction.The given length of any specific transducer cable is a necessary element of its per- formance.
Page 16 056361/F SRD 500 A CAUTION Risk of inoperable device state through failure during software update Updating software through SUSI‘s Flash Update mode is a risky opera- tion, as SUSI writes directly to the device’s flash memory. Furthermore, SUSI cannot verify whether the file supplied is indeed intended for the device under service.
Page 17 The CDU software update can only be carried out with a special RS-232 connection cable, to connect to the receptacle on the CDU PCB. Always check that the correct Sperry Marine cable is available and that the cable is undamaged before executing the CDU software update.

Page 22: System Design And Main Features
The SRD 500 A system combines the proven Doppler transducer and Doppler EU of the former SRD 500 system with the NAVIKNOT CDU and electronics units of Sperry Marine‘s current NAVIKNOT speed log series. The SRD 500 A system has been type-approved by DNV GL SE as Speed...
Page 23: Naviknot Alert Management
SRD 500 A 056361/F A basic system consists of the SRD 500 Doppler Electronics Unit (EU), the NAVIKNOT electronics unit, type 5003, the SRD 500 gate valve trans- ducer and a Control and Display Unit (CDU) of type 5002 or 5001. Up to three additional remote CDUs may be installed.
Page 24: Data Outputs
056361/F SRD 500 A Data Outputs The NAVIKNOT electronics unit transmits speed, distance and depth data to receiving external equipment and to the connected CDUs. While speed and depth data are transmitted as received from the SRD 500 Doppler EU, the distances travelled are calculated from the lon- gitudinal ground and water speeds.
Page 25: Operating Principle
SRD 500 A 056361/F 1.4 Operating Principle To determine longitudinal and transverse ground and water speeds and depth below the transducer, the SRD 500 A utilizes the principle of Dop- pler-shifted sound waves. The SRD 500 Doppler EU uses a microprocessor controlled transmitter to generate a series of short duration ultrasonic pulses.

Page 117: Chapter 5: Sea Chest And Transducer Installation
Chapter 5: Sea Chest and Transducer Installation 5.1 Determining the Transducer Location As early as possible, contact Sperry Marine engineering to receive spe- cific recommendations for the location of the transducer. These recom- mendations will be based upon the principal requirements and general guidelines given below and upon the particular properties of the vessel.
Page 118 056361/F SRD 500 A General Transducer Location Guidelines While the transducer is mounted flush with the hull, it is not affected by boundary layer effects, because return echoes are received from undis- turbed water outside the boundary layer at the hull. However, in common with other sonar devices, the performance of transducer is adversely affected by aeration, i.e.
Page 119 To make sure that the impact on speed log performance is consid- ered, inform Sperry Marine about the location of all bow thrusters and make sure that no bow thruster is added without the knowledge of Sperry Marine.

Page 196: Automatic Transducer Rotation Using Ground Speed
056361/F SRD 500 A Automatic Transducer Rotation using Ground Speed Automatic rotation lets the system automatically compute a transducer rotation angle. To use ground speed for automatic rotation, the water depth below the Transducer must be between one and 200 metres. The ship must be turned into the wind and into the current.
Page 197: Ground And Water Speed Calibration
SRD 500 A 056361/F 9.2 Ground and Water Speed Calibration The ground and water speed displayed and output by the system can be calibrated to correct for measuring errors of up to ± 10%. Separate calibration values are maintained for water and ground speeds.
Page 198 056361/F SRD 500 A • Observe the transverse speeds to determine whether the rotational offset correction procedure should be carried out. It should be car- ried out if the values displayed are considered unreasonable given the actual athwartships motion. • Check that environmental conditions permit proper measurements to be carried out.

Page 244: Troubleshooting If Transducer Shows Ringing
056361/F SRD 500 A Troubleshooting if Transducer shows Ringing “Ringing” is the effect of the transducer resonating at the system’s transmit frequency. This occurs during and just after the transmit pulse. Normally, the ringing should dissipate within the blanking period, i.e. the time of no data processing between the transmit and receive cycles.
Page 245 It is recommended to collect ringing data prior to and just after changing the blanking distance and to send the data to Sperry Marine for analysis. If the vessel is at sea, a slow speed should be maintained while ringing data is collected.
Page 246 A continuous stream of data is written to the BBTalk window.
