Preparations 2-17 Wiring Guidelines and Precautions ATTENTION ! • Do not wire unused terminals. • Make sure to observe correct polarity when wiring the controller terminals. • To reduce induction noise, separate the high-voltage or large-current power lines from other lines, and avoid parallel or common wiring with the power lines when you are wiring to the terminals. We recommend using separating pipes, ducts, or shielded lines.

Preparations 2-19 When mounting a noise filter on the power supply, make sure to first check the filter’s voltage and current capacity, and then mount the filter as close as possible to the Bulletin 900 Controller. Reinforced insulation is applied to the power supply I/O sections. Wiring Input/Sensor Devices Connect sensors to the terminals as follows according to the Input Type and controller.
PAGE 58
2-20 Preparations • To reduce induced electrical noise, the leads on the temperature controller’s terminal block must be wired separately from large-voltage/large-current power leads. Also, avoid wiring leads in parallel with power leads or in the same wiring path. Other methods such as separating conduits and wiring ducts, or using shield wire are also effective and recommended. Wiring Control Output 1 The following diagrams show the available outputs and their internal equalizing circuits. Figure 2.

Chapter 4 Parameter Adjustments & Application Considerations Shifting Input Values Overview The Input Shift parameter allows you to configure the controller to compensate for possible deviation of the measured temperature (PV) to the actual temperature at the source (control target). The controller supports two types of input shifts, 1-point and 2-point. The input shift type is automatically matched to the sensor currently selected by the Input Type parameter (configured value — See Table 3.

Appendix D Glossary Adaptive Tuning: Used to continuously monitor and optimize PID constants while the controller operates. Three tuning algorithms are used to recalculate the PID constants within 500 ms after the process value stabilizes at set point: step-response method, disturbance tuning, and hunting tuning. Anti-Reset Wind-Up (ARW): A feature of PID controllers that prevents the integral (auto-reset) circuit from operating when the temperature is outside the proportional band.
PAGE 400
D-2 Glossary Contact Output: Relay control outputs are often available in these contact forms: • Form A Contact (SPST-NO): Single-pole, single-throw relays use the normally open and common contacts to switch power. The contacts close when the relay coil is energized and open when power is removed from the coil. • Form B Contact (SPST-NC): Single-pole, single-throw relays use the normally closed and common contacts.
PAGE 401
Glossary D-3 Deviation: A departure of a controlled variable from a command such as set point. Deviation Indication: A system of indication in which a departure of a detected value from the set point is indicated. DIN (Deutsches Institut für Normung): A German standards agency that sets world-recognized engineering and industrial standards. DIN 43760: The standard that defines the characteristics of a 100 Ω platinum RTD having a resistance vs. temperature curve specified by a = 0.00385 Ω per degree.
PAGE 402
D-4 Glossary Fuzzy Logic: A rule-based control algorithm that enables control devices to make subjective judgments in a way similar to human decision-making. Within a process controller, fuzzy logic uses some basic information about the system, which is input by the user, to emulate the way an expert operator who was manually controlling the system would react to a process up set. Heat Sink: An object that conducts and dissipates heat away from an object in contact with it.
PAGE 403
Glossary D-5 Loop Break Alarm: This alarm indicates a problem in the control loop, e.g., a sensor has become disconnected or a problem has developed with the final control element. Manipulated Variable: The final output percentage (0…100%) that will be sent to a control element. This percentage can be related to a valve position, a 4…20 mA signal, or the amount of ON time from a pulsed control output.
PAGE 404
D-6 Glossary Process Variable: The parameter that is controlled or measured, such as temperature, relative humidity, flow, and pressure. Proportional Band: The range of temperature in which a manipulated variable is proportionate to any deviation from the set point. Proportional Control Action (P): A control action in which the manipulated variable is proportionate to any deviation from the set point.
PAGE 405
Glossary D-7 Serial Communications: A method of transmitting information between devices by sending all bits serially over a communication channel. RS-232 is used for point-to-point connections of a single device, usually over a short distance. RS-485 communicates with multiple devices on a single, common cable over longer distances. Set Point: The value configured on the process or temperature controller to control the system.
