Error Messages: The Main screen is also used to display error conditions as they occur.

  • Page 26: Target Value Entry

    Use the numeric keys to enter the value. Use the +/- key to change the sign of the value. The 6300-M4 will beep on every key entry, and it will beep for a longer time period if extra invalid digits are entered. It is not necessary to enter the decimal point and the digit after the decimal point if that digit is “0”.
  • Page 27 Remote unit and the main unit. Please abort and contact the factory. If GO is pressed after ENTERing the value, the 6300-M4 will try to achieve this new target value ONLY IF the Pitot output is in the CONTROL mode. Therefore, it is desired that both Pitot and Static values be entered so that both are blinking before the GO key is pressed.

    arrow keys. The selected target value can be “jogged” with the arrow keys until any key other than the arrow keys is pressed. Each time the arrow key is pressed, the selected target value will be incremented (UP arrow) or decremented (DOWN arrow) by a specific amount, depending on the units of the target value.
  • Page 29 Target: 0.064 3000 The unit selection will not become effective until the GO key is pressed. The 6300-M4 will return to the old units if the CANCEL key is pressed. . Static Units: There are four Ps units to choose from: Feet, Ps inHg (Psin), meters, and mbar (Psmb).

  • Page 30: Mode Selection

    The unit selection will not become effective until the GO key is pressed. The 6300-M4 will return to the old units if the CANCEL key is pressed. . It must be noted that the units change does not perform a conversion between the units of feet/minute or meters/minute to Ps inHg/min or Ps mbar/min.
  • Page 31 you want both Static and Pitot outputs connected to the aircraft and both of them achieving a specific target value. Leaving one output in Measure or Leak and the other output in Control should be done only during a Leak check. Static Mode: The Static output has three modes of operation.

  • Page 32: Leak Screen

    6300-M4 is isolated from the output during Measure or Leak modes, it will usually be at a pressure quite different from that at the output. Simply introducing the controlling section into the pneumatic system connected to the output will cause a surge in pressure (or vacuum) at the output.
  • Page 33 Until the first minute has elapsed it shows “WAIT”. While in the Static Leak Screen, if the leak ever exceeds 2000 ft/min, the 6300-M4 will automatically trip out of the Leak mode and revert back to Control mode. It will then display a message as follows: Static leak exceeds 2000 ft/min.

  • Page 34: Self Test Screen

    Pressing the CANCEL key allows you to exit from the Leak Screen, back to the Main Operating Screen. If the mode prior to entering the Leak mode was Control then the 6300-M4 will revert back to Control mode on exiting the Leak Screen.
  • Page 35 There are seven tests performed on the system. These tests check every subsystem for acceptable operation. If a malfunction is detected in any part of a subsystem, that subsystem is flagged as defective. Once a defective subsystem is detected, the self test function is aborted.

  • Page 36: Function Select Screen

    3.5.1 FUNCTION 1 : VIEW LIMITS The 6300-M4 checks both the Target values and the Actual values to determine if they are within specific limits. These limits can be set by the user. To view these limits, you can press the Function Select key and then choose Function 1 (View Limits) by pressing “1”.

  • Page 37: Function 2: Set Limits

    If the target value exceeds any of the limits, an error is generated. The Actual values are also checked when the 6300-M4 is in the “Control” mode. If any of these limits is exceeded by a pre-defined amount, an error will be generated and the 6300-M4 will revert to “Measure”...
  • Page 38 1. Max. knots : This defines the maximum airspeed that can entered as a Target value or generated as an Actual value. Typically this is set to the maximum airspeed that the instruments on the aircraft can tolerate. The maximum value for this limit is 1100 and the minimum is 0.

CURRENT RATE = 250.0 knots /min. NEW RATE = knots /min. min : 50 , max : 500 The knots rate is the rate at which the Actual airspeed value is ramped towards the Target airspeed value.

  • Page 40: Function 5: Setup Profiles

    3.5.5 FUNCTION 5: SETUP PROFILES This function is used to load profiles into the 6300-M4 from a PC. A full explanation of how to load profiles into the 6300-M4 is provided in Section 4.. The following screen will come up when Function 5 is selected.

  • Page 41: Function 7: Set Ground

    The “Set Ground” function is used to indicate to the 6300-M4 the ambient “Ground” pressure. Before connecting the 6300-M4 to the aircraft, just after the Self Test has been performed, it is recommended that this function be invoked. The Pitot and Static ports must still be open to ambient when using this function.

  • Page 42: Profiles

    4.1 WHAT IS A PROFILE. A profile is a set of up to 50 points that tell the 6300-M4 what you would want it to do at each point. Each point consists of 7 parameters: 1) Pitot units, 2) Pitot mode, 3) Pitot target value, 4) Static units, 5) Static mode, 6) Static target value and 7) Static rate (Climb) target value.
  • Page 43 Rate target value In the sample profile, Row 3, which is the first point in the profile, tells the 6300-M4 to go in Control mode to 100 knots on the Pitot side, and in Control mode to 0 feet at 6000 feet/min on the Static side.

  • Page 44: Creating A Profile

    12 characters. On Row 2, middle cell, replace “11” with a profile number between 1 and 20 that you would like this profile to be saved as, in the 6300-M4. Do not change row 2 right-most cell. In rows 3 through 50, change the cells as per the points you want to generate in your test.

  • Page 45: Setting Up Hyperterminal

    Your profile has been created. 4.3 SETTING UP HYPERTERMINAL You download a profile into the 6300-M4 using the Hyperterminal program. At first you need to setup Hyperterminal. You only need to do this once.
