  • Page 20 Proportional Plus Integral Control and Integration Constants In addition to standard proportional control, System 450 provides Proportional plus Integral (PI) control capability. The addition of integral control enables a properly set up analog output to drive a controlled condition closer to Setpoint (Figure 7). Standard proportional-only controls continuously adjust the output in proportion to the difference (offset error) between the setpoint value and the sensor value.
  • Page 21 In addition to a proportional-only setting, System 450 provides six time-integral settings in the Integration Constant Setup screen for matching the analog signal’s response rate to the controlled system’s recovery rate. The seven integration constant settings are shown in Table 9 on page 54. See Determining the Integration Constant for an Analog Output on page 51 for more information and the procedures for determining an integration constant and testing a PI control loop in your controlled system.
  • Page 22 For example, if you select an Output Update Rate value of 5 (seconds), the control module updates the output signal strength every 5 seconds, reducing changes at the controlled equipment to 20% of the default update rate. See Figure 8. Figure 8: Graph Showing Calculated Output Signal Strength and Output Signal Strength Maintained by a 5-Second Update Rate Note:...

  • Page 23: High Input Signal Selection

    Figure 9: Graph Showing Calculated Output Signal Strength and Output Signal Strength Constrained by Output Signal Deadband The Output Deadband feature can be used in conjunction with the Output Update Rate feature, but care must be taken when selecting these values for your control system. In process loops where the condition (temperature, pressure, or humidity) value can change quickly over a large range, the delay in updating the actual output signal strength can cause the controlled equipment to oscillate out of range and drive the process away from the desired setpoint.

  • Page 24: Differential Control

    Differential Control The Differential Control feature enables a System 450 control system to monitor and maintain a temperature, pressure, or humidity differential between two sensors of the same type and control relay, analog outputs, or both based on the sensed differential value relative to user-selected differential values. Differential Control application examples include: •...

    Sensor Failure Mode System 450 allows you to select the mode of operation for your control system outputs in the event of a sensor (or sensor wiring) failure of the sensor (or sensors) that the outputs reference. When you set up an output in the System 450 UI, you must select a sensor failure mode of operation in the Sensor Failure Mode (SNF) screen.

  • Page 37 IMPORTANT: Do not connect supply power to the System 450 modules before checking all wiring connections. Short circuits or improperly connected wires can result in damage to the modules and void any warranty. IMPORTANT: A System 450 control module and module assembly can be connected to an internal power source (a System 450 power module) or an external power source (24 V power connected to the 24V and COM terminals on the control module), but must not be connected to both power sources simultaneously.

  • Page 44 The Select Temperature Offset screens are: • Sensor Type °F, which enables an offset of up to +/- 5°F in 1-degree increments. • Sensor Type °C, which enables an offset of up to +/- 2.5°C in 0.5-degree increments. The temperature offset adjusts the displayed temperature value, sensed at the sensor, by the offset value. For example, if the measured value is 72(°F) without an offset, and a -2(°F) offset is selected, the measured value is offset -2(°F) and the displayed value is 70(°F).

  • Page 45: Setting Up Control System Outputs

    Setting up Control System Outputs After setting up the sensors for your System 450 control system, you can reference the hard-wired sensors (and any functional sensors that resulted from the hard-wire sensor setup) as you set up the outputs. Setting up a Relay Output Relay Outputs provide single and multiple stage on/off control to controlled equipment.
  • Page 46 Note: The condition (temperature, pressure, or humidity), unit of measurement, minimum differential value, default setup values, and condition value ranges available in the output setup screens are determined by the Sensor Type for the sensor that an output references. See Table 5 on page 24 for more information on sensors that are compatible with System 450 standard control modules, their Sensor Types, and the values and ranges associated with each Sensor Type.

In reset control systems, the Main screens also display the Time screen, when the Time parameters are set up.
  • Page 74 (in seconds between 0 and 30) for your EC motor application. For PENN by Johnson Controls EC motors, select a value of 2 (seconds). For other EC motors, start with a value of 1 (second), test the motor application, and increase the value until the optimal pulse period is determined.
  • Page 75 TERM DEFINITION When a pounds per square inch (psi) pressure sensor is set up in your control system, PSI appears in the Main (sensor status) screens, along with the current sensed pressure value. PSI sensors include Sensor Types P 100, P 110, P 200, P 500, and P 750. See Accessing and Navigating the User Interface on page 41 and System 450 Sensors and Transducers for Standard Control Modules on page 10 for more information.
  • Page 76 TERM DEFINITION SENS appears in several screens in the System 450 UI and is associated SENS with either the initial sensor setup screens, or the sensor selection and sensor edit screens in the output setup screens. In the Sensor Setup Start (SENS) screen, press to go to the Sensor Setup screens and set up the hard wire sensors for your control system.
  • Page 77 TERM DEFINITION Sn-d The functional Differential Control sensor (Sn-d) as identified in the System 450 UI. Sn-d is available on standard System 450 control systems (only), when Sn-1 and Sn-2 are the same Sensor Type. The differential control value (Sn-d) is defined as Sn-d = (Sn-1) - (Sn-2). Differential Control is available only on standard control modules and communication control modules.
