Page 42: System Wiring And Installation Guidelines
Preparations Horizontal group-mounting of two or more temperature controllers, or mounting temperature controllers above each other may cause heat to build up inside the temperature controllers. This will shorten their service life. When mounting temperature controllers like this, consider forced cooling measures, such as a cooling fan. If forced air cooling is used, limit cooling to the terminal block.
Page 43 Preparations Do not allow metal fragments or lead wire scraps to ATTENTION fall inside the Bulletin 900 Controller. These may cause electric shock, fire, or malfunction. Never disassemble, repair, or modify the Bulletin 900 Controller with line or field device power applied. Doing so may cause electric shock, fire, or malfunction.
Page 44 Preparations Do not use the Bulletin 900 Controller in the following ATTENTION places which might exceed its specifications: – Places subject to dust or corrosive gases (in particular, sulfide gas, and ammonia gas) – Places subject to high humidity, condensation, or freezing –...
Page 45: Panel Mounting - 900-Tc8
Preparations Store within the following temperature and humidity ATTENTION ranges: Temperature: –25…+65 C Humidity: 25…85% (with no icing or condensation) Avoid using the Bulletin 900 Controller in places near a radio, television configured, or wireless installation. These devices can cause radio disturbances which may adversely affect the performance of the Bulletin 900 Controller.
Page 46 Preparations 4. Tighten the upper and lower adapter mounting screws alternately with only one turn of the screwdriver at a time to maintain an even torque balance. Tighten the screw until the ratchet mechanism operates. 5. To allow heat to escape, do not block the area around the Bulletin 900-TC8 Temperature Controller.

Page 55: Wiring Guidelines And Precautions
Preparations 2-17 Wiring Guidelines and Precautions Do not wire unused terminals. ATTENTION 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.
Page 56: Wiring
2-18 Preparations Figure 2.18 — Wiring 7.2 mm max. 7.2 mm max. Wiring Power Supply The controller requires an external power source for operation.

Page 57 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.
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.

Page 396 C-18 Calibration Checking Indication After calibrating input, make sure to check indication accuracy to make sure that the Bulletin 900 Controller has been correctly calibrated. Accuracy Operate the Bulletin 900 Controller in the PV/SP monitor mode. Check the indication accuracy at the Upper- and Lower-Limits and mid-point.
Page 397 Calibration C-19 Operation: Make sure that the cold junction compensator is at 0 C, and configured STV output to the voltage equivalent to the starting power of the value to be checked.

Page 399 Appendix 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 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.
Page 401 Glossary 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.
Page 402 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.
Page 403 Glossary 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.
Page 404 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 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.
