    Thank you for purchasing your rapidCAST system. Teledyne Oceanscience has a support team in place to assist you with understanding, operating, and deploying your rapidCAST system. Included with your system is documentation regarding the setup and deployment of the rapidCAST. We strongly encourage you to thoroughly read through this documentation to maximize your user experience.
  • Page 8 March 2018 rapidCAST User’s Guide The rapidCAST delivers a probe to a user-specified target depth while the vessel is underway, and re- trieves the probe automatically. Using an entirely new active tension management system, payout behav- ior is precisely controlled to ensure the probe depth is known at all times - even without a conducting ca- ble! Data transfer is achieved using an automated Bluetooth connection.

    March 2018 rapidCAST User’s Guide Lifting the RapidCAST System DO NOT USE THE TENSION ARM AS A LIFT POINT. The tension arm is not load bearing and could be damaged if it is used as a lifting point. The system should be lifted by any of the four (4) handles available on the covers. If the covers are re- moved, the system can be lifted by the frame.

    1645 m of White Line: Normal line used for deployment. • 254 m of “Terminal” Red Line: Bottom part of the spool. The RapidCAST winch software prevents this portion from being paid out, and in fact, automatically stops deployment before this portion of line is reached. If, for some reason, the winch ends up using this segment of line (perhaps through misconfiguration, improper homing, or this safeguard is overridden).

  • Page 37: Line Routing Procedure

    User’s Guide March 2018 Line Routing Procedure IMPORTANT!!! Follow the lockout procedure before routing the line. Before routing the line, remove the short section of Duct Tape (PN 9002203) that is securing the line to the spool. The spools are shipped with the line secured to the spool. Removal of the middle cover may be necessary.

  • Page 44: Adjusting The Levelwind Position

    March 2018 rapidCAST User’s Guide Adjusting the LevelWind Position As line is deployed in or out, the direction of the LevelWind travel and the direction the line as it is rolled off the spool should be in-line with each other. The LevelWind’s reciprocating motion is generated entirely mechanically via rotation of a diamond screw.

  • Page 45: Line Management

    User’s Guide March 2018 Line Management While the probe is in the water or hanging in the air, it pulls on the line and keeps it under tension. This helps prevent line fouling. When the probe is on deck, line is not normally under tension. If the spool is rotated outward while there is no tension on the line, loose loops can form.

  • Page 46: Defining Positions

    To set the Home position: 1. Turn power on to the system and start the rapidCAST Interface software. 2. On the Control Module, set the Control Switch to the Local Control position (joystick control) or PC Control position (use the In, Out, Stop and Speed buttons on the Jog and Teach tab).

  • Page 47: Dock Position

  • Page 49: Launch Position

    Typically set the Recovery position farther out from the Launch position. After the tension-controlled payout has finished, the rapidCAST will start reeling the probe back in. The reel-in speed can be fairly high (up to 200 RPM).

  • Page 55: Auto-Depth Customizable Parameters

    Auto-Repeat disabled, additional casts will not be performed without operator authoriza- tion. This feature ensures that if contact with the depth sounder is lost, rapidCAST Interface will not be using old/outdated depth data. For operational safety, if depth readings resume, the user must manually re-enable Auto-Depth and/or Auto-Repeat, as desired.

  • Page 56: Auto Depth Status

    March 2018 rapidCAST User’s Guide If Reject sentences with bad NMEA checksums is checked, the rapidCAST Interface will calculate the checksums of each message received, and ignore sentences with invalid checksums, thus ensuring that the reported depth readings have not been altered by communication noise.

  • Page 57: Using Auto-Repeat

    The Offset parameter is additive: positive offsets will make the probe fall deeper, negative offsets will make it fall shallower. RapidCAST Interface 1.5.1 introduces a multiplier factor called Coverage. Coverage is a positive-valued parameter that can adjust Nominal Target Depth from 0% thru +100% to give the user increased flexibil- ity in specifying a correction factor.

    March 2018 rapidCAST User’s Guide Shackle Replacement ONLY USE ROPE TO THE REMOVE SHACKLE. Use of hard tools will create burrs and render the shackle useless. To replace the shackle: 1. Loosen and then remove the bolt and flat washer.

  • Page 85: Loop Splice

    User’s Guide March 2018 Loop Splice During intensive surveys, the probe loop splice should be replaced daily by cutting 50cm of line from the end and re-splicing the termination. This will take just a few minutes. The entire line section should be replaced after 1000 casts as a preventative measure.
