    649 unit controls the pressure downstream of the 649B controller itself. The gas enters the 649B controller on the flow meter side and flows in the direction of the flow arrow on the front of the unit. The outlet of the instrument is the controlled pressure port.
  • Page 44 Pressure Signal Output (Pin 2) The 649B controller allows you to access the pressure signal from the pressure transducer, correct it in some way, and re-introduce it into pin 10 of the I/O connector to be used as the input signal in closed- loop control.
  • Page 45 Use pin 10 to introduce another signal, such as a zero corrected pressure signal, into the control circuitry of the 649B controller. When a signal equal to or greater than 0.25V is introduced on pin 10, it overrides the Pressure Output signal (pin 2) until the signal on pin 10 drops below -0.8V.

  • Page 47: Chapter 5 Overview

    Pressure Control Range The 649B controller can control pressure over a range of 5 to 100% of full scale. This means that a 649B controller with a 100 Torr [13.3 kPa] pressure transducer can control pressure from 50 torr [6.66 kPa] to 1000 torr [133 kPa], whereas a unit with a 100 torr [13.3 kPa] pressure transducer can control...

  • Page 48: A Typical Control System

    The 649B controller compares the pressure reading to the setpoint, and positions the valve to maintain, or achieve, the setpoint pressure. The controller functions as a PI (Proportional-Integral) controller. Both the Proportional (P) term, and the Integral (I) term have adjustable dials on the top of the 649B controller.

  • Page 49: Flow Measurement Overview

    Figure 5, page 43, shows the correct location for the 649B controller. When the actual pressure reading is less than the setpoint value, the 649B controller opens the valve to increase the amount of gas entering the system. As the valve opens, gas enters the pressure system, so the pressure rises to meet the setpoint value.

  • Page 50: Tuning The 649B Pressure Controller

    Tuning optimizes the way the 649 unit controls your system. The Proportional (P) and Integral (I) terms adjust the response of the 649B controller. The controller responds to changes in either the pressure of the system or the value of the setpoint.

  • Page 51: Integral Term

    5.4.3 Tuning the 649B controller Tuning the 649B controller involves adjusting the Proportional and Integral terms to optimize the response of the controller in your system. Since every system is different, the optimum settings for the P term and I term will vary. Also, the response of the system to increasing and decreasing pressures may vary.
  • Page 52 REV- C 1023590-001 The following graphs show the response of the 649B controller to changes in the setpoint. The setpoint changed from 4 torr [533 Pa] (2 Volts) to 6 torr [800 Pa] (3 Volts), and back again. The following three graphs were generated on a system consisting of a...

    (pin 2) or any signal on the Optional Input pin (pin 10) to the setpoint. The 649B controller positions its valve to achieve or maintain the setpoint pressure (or other variable if the Optional Input is used) in the system. Closed-loop control mode has the lowest priority.

  • Page 55: Trip Points

    1023590-001 Trip Points The 649B controller provides two trip points (Trip Point A and Trip Point B). Each trip point operates independently and controls an open collector output that can be connected to an external relay. Each trip point has an adjustment pot, a status LED, and a test jack. Refer to Figure 6. for the location of the trip point adjustment pots and LEDs.

  • Page 56: Applications With A Large Differential Pressure

    A normally closed valve may be unable to open. Labels The 649B controller carries a serial number label which identifies the serial number, model number, calibration gas, full scale flow rate, and pressure range. It also displays the CE Mark which indicates compliance with European directives.

  • Page 57: Chapter 6 Operation

    Check the pressure transducer zero before operating the unit initially and then periodically as required. The zero can be set (or reset) by adjusting the zero potentiometer located on the top cover of the 649B controller or, on the front panel of an MKS Power Supply/Readout if you are using one.

  • Page 58: How To Adjust The Pressure Transducer Span

    Only adjust the pot in conjunction with a calibration transfer standard. Do not adjust the span SPAN setting if a calibration transfer standard is not available. Instead, contact an MKS Service Center for calibration. How to Zero the Integral Mass Flow Meter Ensure that no gas flow is entering the 649B controller.

  • Page 59: How To Tune The 649B Controller

    How To Tune the 649B controller You may need to tune the 649B controller to optimize how it controls your system. Tuning consists of varying the P (Proportional) and I (Integral) parameters to achieve the fastest, smoothest response to changes in the setpoint value.
  • Page 60 Stop the gas flow through the 649B controller. 2. Remove any leads or wires attached to the connector on the 649B controller. 3. Use a 4.8 mm hex wrench (or open-ended wrench) to remove the hex nuts on each side of the I/O connector.

  • Page 61: How To Select The Trip Point Action

    Equipment required: 4.8 mm hex or open-ended wrench The 649B controller is initially configured with TP A set to trip high (it is on when the pressure is above the trip point pressure) and TP B set to trip low (it is on when the pressure is below the trip point pressure).

  • Page 62: How To Use Trip Points As Error Indicators

    47.5 to 52.5 torr [6.333 to 6.999 kPa]. The 649B controller is initially configured with TP A on above the trip point and TP B on below the trip point. If you have not changed the action of either trip point, you may follow the steps below. If you have changed the action of the trip points, you need to reset them back to the initial configuration for this example.
  • Page 63 Should the pressure deviate from this range the appropriate trip point will turn on and its LED will illuminate. Trip Point A will turn on when the pressure exceeds 52.5 torr [6.999 kPa] and Trip Point B will turn on when the pressure falls below 47.5 torr [6.333 kPa]. 63 649B USER MANUAL...
