Temperature Controller
Instruction Sheet
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.
Caution
DANGER! Caution! 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.
WARNING!
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 internal 249
Ω
precision resistor for the current input is built-in, please refer to the item, How To Set Up Current Input.
Note 2: Factory setting: PT100 input. It is adjustable for linear input and feedback ranges. The default range of input feedback is -999 ~ 9,999. For
example, when a 0 ~ 20mA analog input is selected as the input temperature sensor type, -999 indicates 0mA and 9,999 indicates 20mA. If
change the input range to 0 ~ 2,000, then 0 indicates 0mA and 2,000 indicates 20mA. One display scale is equal to 0.01mA.
Output Function
Output control for DTC is selective: Control output (heating, cooling), Alarm output, or Retransmission output.
Control Output:
Temperature can individually be controlled by two groups of outputs: cooling (forward) or heating (reverse). When Dual
Loop output control is used, two output controls shall be designed for cooling (forward) or heating (reverse). If two
control outputs with the same direction are performed, only 1
st
group control period is valid. Control methods: PID
control, ON/OFF control, Manual control, and PID program control.

Description of Function and Parameters Setting:
PID program control by 8 patterns (Pattern No. 0~7) is supported in DTB series. Each pattern contains 8 steps (step
No. 0 ~ 7), one Link Pattern parameter, one Cycle parameter and one Actual Step parameter.
Start Pattern:
is in operation mode and it is used to set the Start Pattern of PID program control (This
parameter appear in
mode only).
Steps:
Include set point X and execution time T, these two parameters setting. The set point (SV) should reach
temperature X after the period of execution time T. If the set point is the same as the result of the previous setting,
then it is called Soak program control. If not, then it is called Ramp program control. Therefore, PID program control is
also called Ramp/Soak program control.
The default of step No. 0 in this controller is Soak program control. The controller will control the temperature (PV) to
reach the set point X and then keep the temperature at set point X. The period of execution time is time T which
provided by step No. 0.
Link Pattern Parameter:
For example, when set
to 2, it indicates that pattern No. 2 will execute next after the
execution of pattern No. 0. If set to
, it indicates the program will stop after executing the current pattern and
the temperature will keep at the set point of the last step.
Cycle Parameter:
Additional execution cycle number. For example, when set
to 2, it indicates that pattern No.
4 should execute twice in addition. Including the origin one time execution, the pattern executes totally three times.
Actual Step Parameter:
Execution step number per pattern (can set to 0 ~ 7). For example, when set
to 2, it
indicates that pattern No 7 will not execute other steps than step 0 to step2.
Execution:
When
is set to
, the program will start to execute in order from the step 0 of start pattern.
When
is set to
, the program will stop and the control output is disabled.
When
is set to
, the program will stop and the temperature at that time will be controlled at the set point
before program stop. Select
again, then the program will restart and execute from step 0 of start pattern.
When
is set to
, the program will hold and the temperature at that time will be controlled at the set point
before program hold. Select
again, then the program will follow the step before hold and start to execute
through the rest of the time.
Retransmission Output:
When the 1
st
group output of this controller is linear voltage or current output, it can be Retransmission that is the output
variation corresponding with input. For example, when read value = 0 with input range 0 ~ 1,000, output will be 0mA or
0V. When read value = 1,000, output will be 20mA or 10V.
