DTC1000/2000 Temperature Controller

User Manual

Thank you very much for purchasing DELTA C Series Temperature Controller. Please read this

instruction sheet before using your C series to ensure proper operation and please keep this

instruction sheet handy for quick reference.

1 Precaution

DANGER: ELECTRIC SHOCK!

DTC1000 is an OPEN-TYPE Process Control Equipment and DTC2000 is an OPEN-TYPE

Process Control Accessory. These devices are microprocessor-based temperature regulating

controllers which may be provide with normally closed and/or open contacts. They are

intended for installation completely within an overall panel or Process control Enclosure and

are used in heating or cooling applications. Please Install within a separate UL Listed

enclosure only, keep the enclosure away from airbome dust or high humidity and prevent

electric shock or sudden shock. Also, it is equipped with protective methods such as some

special tool or key to open the enclosure, so as to avoid the hazard to users or any damage to

the module.

1. Prevent dust or metallic debris from falling into the controller that will cause malfunction.

2. Do NOT modify or disassemble the controller.

3. Do NOT connect to “No Used” terminal.

4. Do not install and/or use the controller in places subject to:

(a) Dust or corrosive gases and liquid. (b) High humidity and high radiation. (c) Vibration and

shock. (d) High voltage and high frequency

5. Power off when wiring and changing an input sensor.

6. Be sure to use compensating wires that match the thermocouple types when extending or

connecting the thermocouple wires.

7. Shorten the wire when wiring a platinum resistance thermometer (RTD) to the controller and

separate power cable from load wires to prevent interference and conductive influence.

8. Make sure power cables and signals device are installed properly before power on; otherwise

serious damage may occur.

9. Do NOT touch the terminals or repair the controller when power on to prevent electric shock.

10. Wait at least one minute after power off to allow capacitors to discharge, and do not touch any

internal circuit within this period.

11. Do NOT touch internal terminals no matter power on or off.

12. For temperature accuracy, keep the controller away from heating source.

Note 1: an external 250Ω precision resistor is needed for current input. Note 2: factory setting: PT100 input. It is adjustable for linear input and feedback ranges. The default range of input feedbadk is –999~9999. For example, when a 0~20mA analog input is selected as the input temperature sensor type, -999 indicates 0mA and 9999 indicates 20mA. If change the input range to 0 ~ 2000, then 0 indicates 0mA and 2000 indicates 20mA. One display scale is equal to 0.01mA.

SV Alarm Type value is lower than the setting value SV+(AL-L). Hysteresis lower-limit alarm output: This alarm output operates if PV value is lower than the 12 setting value SV-(AL-H). This alarm output is OFF when PV value is higher than the setting value SV-(AL-L). Alarm Output Function ON OFF AL-H AL-L st Attention: AL-H and AL-L include AL1H, AL2H and AL1L, AL2L. When the 1 group output is set to alarm output, AL1H (1024H) and AL1L (1025H) will be used.

Bit=0 means no password setting. Bit=1 means password is set (b0~b2). b3~b6 are used for displaying current password status. 9 SYNCHRONOUS COMMUNICATION PROTOCOL & AUTO NUMBER ID FUNCTION By using Auto Number ID function, the communication protocol of DTC2000 can be set the same as the one of DTC1000. ID numbers tend to increase. 1. Set the auto communication flag to be “1” for DTC1000 (communication address 1022H). 2. Switch off the controller before connecting to another DTC2000.
