    Controller Housing The standard Titanium controller housing is pressure resistant to 7,000 meters. For more shallow depths, a 5,500 meter rated aluminum housing is available. A deep controller housing option is rated to 10,000 meters. The controller housing holds the battery pack for 14 ‘C’ cell alkaline batteries, and the electronics assembly.

  • Page 19: O-Rings

    O-Rings The Sediment Trap end cap o-rings are custom-made. O-rings must be installed properly and kept in place at all times. Each set includes three custom o-rings (200-0071, 200-0072, 200-0073). See Chapter 6, ‘Maintenance and Storage’ for detailed instructions on cleaning the o-rings and positioning the o-rings when inserting the end cap into the controller housing.

    Drive Motor The drive motor assembly contains the following: • A high-torque electronic stepping motor • A reducing gear train • A microswitch/cam device • A titanium main drive shaft The motor’s main drive shaft generates 30 kg/cm torque at the spur gear. A switch and cam assembly in the stepper motor confirms proper alignment of each bottle.

  • Page 24: Sediment Trap Toolkit

    Sediment Trap Toolkit Each Sediment Trap comes with a toolkit that contains tools, materials, and devices to use the Sediment Trap. The toolkit and contents are referred to throughout this User Manual, and should remain with the instrument at all times. Figure 1-16: Sediment Trap Toolkit The Sediment Trap toolkit in Figure 1-16 is shown only as an example.

  • Page 25: Electronics Components

    Electronics Components The Sediment Trap firmware runs on the Persistor CF2 microcontroller. Older Sediment Trap systems use the TattleTale 8 (TT8) microcontroller. The TT8 was discontinued, and McLane instruments now use the CF2. While most of this User Manual can apply to both current and older McLane instruments, significant firmware, hardware, and procedural changes have been made to the Sediment Trap with the CF2 microcontroller and some sections will not apply to older systems.

    Main Battery The Sediment Trap battery holder holds user replaceable drop-in ‘C’ cell batteries. Be sure to install the batteries with the correct orientation in the holder terminals. An instructional video showing drop-in battery replacement is shown on the Sediment Trap video pages at www.mclanelabs.com. Figure 1-18: Drop-in Battery Holder for ‘C’...

  • Page 27: Backup Battery

    Backup Battery After the spring of 2015, new McLane CF2-based instruments no longer require a backup battery. Prior to this change, the backup batteries served as a voltage source for the electronics while in low power sleep mode. Electronics hardware changes made the backup battery unnecessary, and it was eliminated.

  • Page 29: Chapter 2 Getting Started

    Chapter 2 Getting Started The Sediment Trap toolkit includes a COM cable for connecting the sampler to a host computer. You must also install the McLaneTerm terminal emulation program on your computer. Topics Covered: • Connecting to a computer. • Installing and configuring terminal emulation software on a computer.

  • Page 30: Troubleshooting The Usb Adaptor

    The COM bulkhead connector is a 5-pin MCBH style. Some instruments may have a 3-pin XSG style bulkhead connector (Figure 2-2). Both style cables have a serial connector. The serial connector either plugs directly into the computer or into the USB to RS-232 adaptor and then into the computer.

Follow the steps in the McLaneTerm User Manual to install and configure this terminal emulation software. When communication with your McLane instrument is established, Proceed to the section that follows next in this User Manual “Powering up the Sampler”.

  • Page 32: Opening The Controller Housing

    Opening the Controller Housing Attention and care should be taken in maintaining, operating, and opening the pressure housing. All samplers shipped after summer 2015 have a pressure relief valve (PRV) on the controller housing. This valve releases automatically at a pressure differential greater than 10psi. The PRV style may have a center hole and release tool, or the style may have a flat relief valve that must be manually pulled out.
  • Page 33 Figure 2-5: Releasing Pressure Relief Valve (Style with Release Tool) 1. Disconnect the cables from the end cap (if connected). 2. Slowly pull on the pressure relief valve to release any vacuum or built up pressure in the housing. 3. Loosen each end cap bolt a few turns at a time in a star pattern. 4.

  • Page 35: Establishing Communication

    Backup batteries are not installed with firmware v3.12 and higher. Electronics hardware changes made the backup battery unnecessary and it was elminated. If deploying a Sediment Trap that still has a backup battery, install a fresh battery before every deployment. Establishing Communication 1.

    Chapter 6 Maintenance and Storage Proper maintenance after every deployment is critical for ensuring smooth operation and long instrument life for your Sediment Trap. Reference lists are provided in this chapter for guidance on the maintenance recommendations immediately following the recovery, upon returning to a lab setting, and to prepare for long term storage.

  • Page 76: Rinsing The Sediment Trap

    Rinsing the Sediment Trap Rinsing the cone, controller housing. motor and rotator with fresh water immediately following recovery is extremely important for long-term care of your Sediment Trap. The results of skipping this procedure can directly affect the condition and future performance of your instrument. Figure 6.1-1 shows the results of poor rinsing directly following deployment.
