1 igital Temperature Controller C// C C C eneral escription new set of controllers has been added to the C Series to provide additional configuration flexibility. These instruments have a third contact that can be configured as an analog retransmission output, a digital contact output for /STOP status or a third alarm and a contact input for / or /STOP functions. These instruments are designed for heat only operation and are available in either reverse or direct control action. The Heat/Cool output or digital communications are not available on this series.

2 C C T OT OT M M T OT OT M M igital Temperature Controller C// Features Heater reak larm Self-Tuning lgorithm The heater break alarm (H) detects a fault in the heating or cooling circuit and displays actual amperage in the display on the front panel. If the measured value becomes lower than the preset value, the alarm is activated. The H function requires a current detector for measuring and monitoring the current load. The C Series offers a new self-tuning feature that is initiated at start-up and when process parameters or conditions change. In these situations, the controller evaluates whether the preset PI parameters should be maintained or replaced by the latest self-tuning parameters to achieve the best control for the process. Self-tuning can be manually turned O/OFF in the parameter setting mode. This feature is not available with the Heat/Cool control. Sensor In addition to self-tuning, The C Series has standard autotuning (T) so that either function can be selected to achieve optimum process control. Heater Controlled object CT ctuator Mechanical relay, SS Temp t start-up or set value change When overshoot occurs, self-tuning is initiated When control disturbance occurs, self-tuning is initiated Oscillation CT--P- ( to ) CT--S-- ( to ) ength of lead wire : pprox. mm (standard) oop reak larm ength of lead wire : pprox. mm (standard) φ. φ The loop break alarm () monitors and protects an entire temperature control system. The detects heater breaks, thermocouple or T failures, short circuits, or the failure of an operating device such as a mechanical or solid state relay. When the PI computed value reaches % and the temperature does not respond in a set time, the loop break alarm is activated. Conversely, when the PI value reaches % and the temperature does not respond accordingly, the loop break alarm is turned on. In this example, the uses reverse action to control heat. For cool control, the action is reversed and becomes direct. deadband is available to suppress the influence of external disturbances. Close Horizontal Mounting The C Series has been designed with a unique mounting bracket that allows close horizontal mounting of multiple instruments to save valuable panel space.
