Delta Products DTC Series Instruction Sheet

Series Digital Controller

Instruction Sheet

Thank you very much for purchasing DELTA DTC Series Temperature Controller. Please read this instruction sheet before using your DTC
series to ensure proper operation, and please keep this instruction sheet handy for quick reference.

 Caution

DANGER! Caution! Electric Shock!

DTC series is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust, humidity, electric shock and
vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key or specific tools are required to open the
enclosure) in case danger and damage on the device may occur.

WARNING!

1. Prevent dust or metallic debris from falling into the controller that will cause malfunction. DO NOT modify or disassemble the controller.

DO NO use extra terminals.

2. 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

3. Switch off the power when wiring or changing input sensors.

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

5. 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.

6. Make sure the power cable and signals device are installed correctly before switching on the power of DTC; otherwise serious damage

may occur.

7. DO NOT touch the terminals or repair the controller when the power is on to prevent electric shock.

8. Wait at least one minute after the power is off to allow the capacitor to discharge. DO NOT touch any internal circuit within this period.

9. DO NOT touch the internal terminals no matter the power is on or off.

10. DO NOT place other heating source (e.g. power supply) in parallel with DTC during the installation. Please keep proper space in

between.

Note 1: The current input is built-in with 249 precision resistor. See “How To Set up Current Input” section.
Note 2: Default setting: Pt100 input.
The range of linear input and feedback value is adjustable. Range of input feedback: -999 ~ 9,999. Take 0 ~ 20mA input as example, -999

refers to 0mA input, and 9,999 refers to 20mA input. If we change the range to 0 ~ 2,000, 0 will refer to 0mA input, and 2,000 will refer to 20mA
input. 1 display scale = 0.01mA.

 Output

There are several output types available from DTC series: Control Output (heating/cooling), Alarm Output and Proportional Output.

 Control Output

DTC series offers 2 outputs for heating or cooling control. If you require dual loop output, the 2 outputs should be set to different actions
(heating or cooling). If you require the 2 outputs are set to the same control action, only the control cycle of output 1 will be valid, and the 2
outputs will act at the same time.

The control methods include: PID control, ON/OFF control, Manual control and programmable PID control.
