  • Page 46: Measure To Control Transition

    Simply introducing the controlling section into the pneumatic system connected to the output will cause a surge in pressure at the output. To prevent such a surge, the 6600-NG measures the pressure at the output, shuts-off the output from the internal 6600-NG pneumatics, and then controls the pressure within the internal control mechanism to match the pressure at the output.

    Otherwise, allow the test to continue until the final target altitude is reached. Note: The power supplied on the Encoder interface connector of the 6600-NG is +12 Volts DC. If the encoder being tested requires a different voltage, it will need to be supplied externally. If this is done, the Ground of the external power supply must be connected to the Ground (GND) pin of the Encoder interface connector.

  • Page 66: Leak-Checking The 6600-Ng

    6600-NG contributes less than 10% to the leak with the aircraft connected. Therefore, an internal leak of 100 ft/min in the 6600-NG will contribute only 10 ft/min (or less) to the leak measured with the aircraft connected.

  • Page 67: Section 4 : Profiles

    WHAT IS A PROFILE A profile is a set of up to 50 points that tell the 6600-NG what you would want it to do at each point. Each point consists of 12 parameters: 1) Pt units, 2) Pt mode, 3) Pt target value, 4) Pt Rate target value, 5) Ps1 units, 6) Ps1 mode, 7) Ps1 target value, 8) Ps1 Rate target value, 9) Ps2 units, 10) Ps2 mode, 11) Ps2 target value and 12) Ps2 Rate target value.

    6600-NG User’s Manual SECTION 7 : MAINTENANCE Scheduled maintenance of the 6600-NG includes calibration once a year. The calibration procedure is described in Section 6. Calibration of the 6600-NG must be done only at an Authorized Calibration Center. Other than annual calibration, there are no other scheduled maintenance requirements.

    On the PC, the COM1 serial port (or any other COM port) or a USB port (configured as a COM port) can be used to communicate with the 6600-NG. If a USB port is used, it is necessary to use an in-line USB to RS232 converter.
  • Page 86 If there are 5 commands in the buffer, all 5 will be processed within one 250 msec period. So it can take anywhere between 10 msec and 360 msec for the 6600-NG to respond to a command, depending on when the command is received and the operating state of 6600-NG.
