1 No. CP SS 89E Single Loop Controller SDC5/6 Features The DigitroniK SDC5/6 is a digital indicating controller featuring multi-range inputs and PID control system using new algorithms "RationaLOOP" and "Just- FiTTER". Up to two control output points (this number of points may vary depending on the model) can be used, which are selectable from the relay contact, voltage pulse, and current. The smart loader package ensures easy setting operation and monitoring. This controller is compliant to the IEC directives and the CE marking. Space saving design with a depth of 65mm. The mask of the front panel is also only 5mm thick. High accuracy of ±.%FS and sampling cycle of.s (seconds). Multi-range inputs are available for selection, where the input type can be freely changed among thermocouple, RTD, current, and voltage. The control method can be selected from any of the / OFF control and PID control using "RationaLOOP" + "Just-FiTTER". The heat/cool control can be achieved using two control output points and event outputs. The PC loader port is provided as a standard function. The control output types available for selection are relay, voltage pulse, and current outputs. The heat /cool control can be achieved by interfacing with the nd control output in combination with these outputs. Event points or points (independent contact), CT input points, DI 4 points, and RS-485 can be selected in combination. The smart loader package (SLP-C5) can be used.

5 Event Event type Loop diagnosis shows that the /. this value. This event is used to detect any fault of final control devices. shows that the / a point that "U" is added to this value. The event is turned when any change in corresponding to increase/decrease in (Manipulated variable) is not observed. Setting items : Change in from the point that the reaches the upper limit (%) or lower limit (%). : Range of absolute value of deviation ( ) allowing the event to turn OFF. delay time: Diagnosis time OFF delay time: A period of time from power allowing the event to turn OFF. Operation specifications The direct action is used for the heat control. The event is turned when the increase in becomes smaller than the main setting after the diagnosis time ( delay time) has elapsed from the time that the had reached the upper limit, or when the decrease in becomes smaller than the main setting from the time that the diagnosis time ( delay time) has elapsed from the time that the had reached the lower limit. The reverse action is used for the cool control. The event is turned when the decrease in becomes smaller than the main setting after the diagnosis time ( delay time) has elapsed from the time that the had reached the upper limit, or when the increase in becomes smaller than the main setting after the diagnosis time ( delay time) has elapsed from the time that the had reached the lower limit. The event is turned OFF regardless of other conditions when the absolute value of the deviation ( ) becomes less than the sub-setting. The event is turned OFF regardless of other conditions when a period of time after starting of operation from the time that the power has been turned becomes less than the OFF delay time. However, the event is turned OFF when the absolute value of the deviation is the (sub-setting hysteresis) value or less after the absolute value of the deviation has become the sub-setting or more.

6 Event Event type r (status) shows that the / this value. shows that the / a point that "U" is added to this value. The direct and reverse action settings are disabled for the timer event. When using the timer event, it is necessary to set the operation type of the DI allocation to "r Start/Stop". Additionally, when setting the event channel designation of the DI allocation, multiple timer events are controlled from individual internal contacts (DI). Setting items delay time: A period of time necessary to change the event from OFF to after DI has been changed from OFF to. OFF delay time: A period of time necessary to change the event from to OFF after DI has been changed from to OFF. Operation specifications The event is turned when DI continues for delay time or longer. The event is turned OFF when DI OFF continues for OFF delay time or longer. In other cases, the current status is continued. DI delay OFF delay Internal event CAUTI When setting the delay and OFF delay, it is necessary to put in "Multi-function setup". The default settings of the delay and OFF delay before shipment are.s. The default setting of the event channel designation of the DI allocation before shipment is "". In this case, the timer event start/stop can be set for all internal events from one internal contact (DI). Additionally, as one or more event channel designation is set, the timer event start/stop can be set for one internal event specified by one internal contact (DI). However, when setting the event channel of the DI allocation, it is necessary to put in "Multi-function setup". Direct/, standby, and READY operations can be set when setting up each event (E.C to E5.C).

Preventive measures against noise of instrument power supply () Reduction of noise Even though the noise is small, the noise filter is used to eliminate the effect of the noise as much as possible. Instrument power supply to 4Vac Noise filter C5 C6 () When noise is excessive If a large amount of noise exists, appropriate isolation transformer and line filter are used to eliminate the effect of the noise. Instrument power supply to 4Vac Other circuit Insulation transformer (/V) (/V) Line filter Yamatake's model No. E (Equivalent to ZAC5-U made by TDK) Grounding E GND 4. Installation environment noise sources and preventive measures Generally, the following may be the noise sources in the installation environment: Relay and contact, electromagnetic coil, solenoid valve, power supply line (particularly, Vac or more), motor commutator, phase angle control SCR, radio communication device, welding machine, high-voltage ignitor, etc. Preventive measures against fast rise noise Use of CR filter is effective to prevent fast rise noise. Recommended filter: Yamatake's model No (Equivalent to 95M5 made by Matsuo Electric.) 4. Wiring precautions () After taking the noise preventive measures, do not bundle the primary and secondary power cables together or put both power cables in the same conduit or duct. () Keep the input/output and communication lines 5 cm or more away from the power lines and power supply lines having a voltage of Vac or more. Additionally, do not put these lines together in the same conduit or duct. 5. Inspection after wiring After the wiring work has been completed, always inspect and check the wiring status. Great care should be taken since incorrect wiring may cause the instrument to malfunction or severe personal injury.
