    CHIRP 3260 BREAKDOWN ........

  • Page 4: Introduction

    Please note that the Chirp 3260 echosounder contains modules that can generate several hundred volts at the secondary of the output transformer. Extreme care and proper understanding is required upon removal of the protective covers and exposure to these modules.

  • Page 5: Chirp 3260 Breakdown

    CHIRP 3260 BREAKDOWN For the purpose of this manual the Chirp 3260 will be broken down into five sections. They are the Front Panel, The Power Supply Section, The Transmitter Section, the Processing Section, and the Rear Panel. Figure 1 shows the location of each section within the Chirp 3260 echosounder.

    If you turn on the System Power switch on the front panel and the light does not activate it could be that the bulb or fuse has blown or a failure has occurred inside the Chirp 3260.

  • Page 7: Voltage Checks

    Voltage Checks The AC supply voltage to the Chirp 3260 is fed to four AC to DC voltage converters in order to create the DC supply voltages for the internal modules. The three larger voltage converters (48V each) combine to create the 144V rail voltage used by the bank of high power transmitter modules.
  • Page 8 CHIRP 3260 TROUBLESHOOTING AND MAINTENANCE MANUAL With the fan plate removed from the system you will find that each transmitter module is installed in a backplane configuration. With the capacitor bank drained the transmitter module(s) can be pulled straight up and out of the backplane sliding on the card guides.

  • Page 9: Communication Issues

    If upon running of the EchoControl Client or Server software applications on the host PC you experience an error stating “no USB devices found” please enure that the Chirp 3260 echosounder is powered on and that the external USB connection on the Rear Panel is solid and secure. If the problem continues please try another possible USB cable or USB port on the host PC.

  • Page 10: Maintenance

    MAINTENANCE Performance Checks As part of a regular maintenance plan the Chirp 3260 can be interfaced with a Knudsen EchoSim signal simulator. Using the EchoSim will allow checking of the Chirp 3260 transmitting and receiving capabilities. Regular checks of the overall system output power will help determine if one or more of the transmitter modules are not performing at their maximum potential.
