WARNING Do not disassemble the SDC15. Doing so might cause electric shock or faulty operation. Before wiring, or removing/mounting the SDC15, be sure to turn the power OFF. Failure to do so might cause electric shock. Do not touch electrically charged parts such as the power terminals. Doing so might cause electric shock.

This chapter lists up the display items of this unit and their contents. Chapter 7. CPL COMMUNICATIONS FUNCTIONS This chapter describes how to communicate this unit with a host unit, such as a personal computer or PLC through Yamatake's standard CPL communication using RS-485. Chapter 8. MODBUS COMMUNICATIONS FUNCTIONS This chapter describes how to communicate this unit with a host unit, such as a personal computer or PLC through MODBUS communication.
The following conventions are used in this manual: Handling Precautions : Handling Precautions indicate items that the user should pay attention to when handling the SDC15. : This indicates the item or page that the user is requested to refer to. Note : Notes indicate useful information that the user might benefit by knowing.
Chapter 3. INSTALLATION CAUTION Use the SDC15 within the operating ranges recommended in the specifications (temperature, humidity, voltage, vibration, shock, mounting direction, atmosphere, etc.). Failure to do so might cause fire or faulty operation. Do not block ventilation holes.

Chapter 4. WIRING WARNING Before wiring, or removing/mounting the SDC15, be sure to turn the power OFF. Failure to do so might cause electric shock. Do not touch electrically charged parts such as the power terminals. Doing so might cause electric shock.
When necessary, an appropriate external resistor is connected in series so that the voltage between the input terminals of the SSR you are using is within the specified range. (Example) Connection of two Yamatake PGM units Connection diagram External resistor R1 V: 19V ±...

If the noise from the power supply is large, an appropriate insulation transformer is added to the power supply and an appropriate line filter is used. (Yamatake's line filter model No.: 81446364-001) If the noise has fast rising edge, an appropriate CR filter is used.

Set value 2 (stability) is adjusted to the process that the heater heating indirectly affects the PV to aim at the adjustment considering the stability. When compared to the AT functions of Yamatake's conventional models, set value 1 (immediate response) is close to the SDC10 and set value 0 (normal) is close to the SDC20/21.

• The settings, which cannot be changed by the key lock, cannot be displayed in the password lock mode. • If the password lock cannot be unlocked, contact Yamatake or its dealer. By returning the setting to the initial setting at Yamatake’s factory, the password lock can be unlocked.

When the control output 1 7: CT1 current value type is related to the PV and 8: CT2 current value SP, the decimal point 9: MFB (Invalid on SDC15) position becomes the same Control output 1 -1999 to +9999 as that of the PV.

■ Features The features of the SDC15's communications functions are as follows: • Up to 31 SDC15 units can be connected to a single master station as a host device. • When the communications specifications of the host device conform to the RS- 232C interface, the communications converter CMC10L (sold separately) is required.
The communications procedure is as follows: (1) The instruction message is sent from the host device (master station) to one SDC15 unit (slave station) to communicate with. (2) The slave station receives the instruction message, and performs read or write processing according to the content of the message.
Page 154
The device returns the same station address as that received as the response message. • Sub-address The SDC15 does not use the sub-address. For this reason, set "00" (30H 30H). The device returns the same sub-address as that received as the response message.

A/D conversion A/D converter is faulty. It is thought that the main failure body needs to be replaced. Contact Yamatake or its dealer. Set data failure Data is corrupted by noise. Turn ON the power again. Power is shut-down while the If the same alarm occurs data is being set.
However, note that another message appears when inspecting the LED. Handling Precautions • Yamatake shall not be held responsible for any defects arising from improper calibration made by the customer. • To return the unit to the calibration status of the default settings before shipment during calibration, follow the steps below.
