DTC1/2 Temperature Controller User Manual Thank you very much for purchasing DELTA C Series Temperature Controller. Please read this instruction sheet.
Alarm output will be enabled when the temperature reaches the upper limit.
Alarm will be enabled when the PV exceeds SV + AL-H.
Alarm output will be enabled when the temperature reaches the lower limit.
Alarm will be enabled when the PV falls below SV – AL-L.
Alarm will be enabled when the PV is between SV + AL-L and SV – AL-L.

Alarm will be enabled when the PV reaches SV and falls below SV – AL-L
11
Alarm will be enabled when the PV exceeds SV + AL-H and disabled when
Lower limit hysteresis alarm
Alarm will be enabled when the PV falls below SV – AL-H and disabled
Note: AL-H and AL-L include AL1H, AL2H, AL1L and AL2L. When Output 1 is set to Alarm Output, use AL1H (1024H) and AL1L
(1025H). When Output 2 is set to Alarm Output, use AL2H (1026H) and AL2L (1027H).
1. When power is normal, POWER LED will be on.
2. After DTC1000/2000 is switched on, all LED will be on. The communication protocol will be displayed in 1 second,
followed by the communication address in the next second.
4. ERROR LED is on when errors occur in input, memory or communication.
5. When an output is executing, its corresponding output LED will be on.
6. AT LED flashes when PID parameters are being auto-tuned.
7. RX LED flashes when DTC1000/2000 receives communication signals. TX LED flashes when DTC1000/2000
Communication protocol displayed on LED after the power of DTC1000/2000 is switched on:
TX
O1
010: 9,600bps
011: 19,200bps 100: 38,400bps
Communication address display: AT (bit 6) and Run (bit 0) are combined to binary code.
The default setting of the password is disabled. To enable the password function, enter the 4-character password in the
specific communication address. The password is protected by 3 levels.
1. Level 1: Only LED status, SV and PV can be read. No settings can be modified.
2. Level 2: Only LED status, SV and PV can be read. Only SV can be modified.
3. Level 3: All SV can be read. Only SV and auto-tuning can be modified.
When a password is set (in 106EH ~ 1070H), the protection will enter Level 1. To enter other levels, enter the
corresponding password (in 106BH ~ 106DH). After DTC1000/2000 is switched off, the protection will return to Level 1.
To unlock the password protection, the user has to remove all the passwords (in 106EH ~ 1070H).
The password protection level can be read in 106EH ~ 1070H:
b0
b2

Level 2
Level 1 locked
bit = 0 refers to no password is set. bit = 1 refers to the password has been set (b0 ~ b2). b3 ~ b6 display the current level status.
Synchronous Communication Protocol & Auto ID Setup
This function allows the user to set the communication protocol of DTC2000 to the same protocol as set in the first
DTC1000. The station IDs of DTC1000/2000 are arranged in decreasing order. Follow the steps below.
1. Set the auto communication ID of DTC1000 to '1' (communication address: 1022H).
2. Switch off DTC1000 before connecting it to DTC2000. Switch it on again.
Dtc P1000
3. Default communication protocol: 9,600bps, 7 bits, Even, 1 stop bit, communication address 01.
4. This function will consume 3 ~ 5 seconds more when you switch on your DTC.
1. Supports transmission speed: 2,400, 4,800, 9,600, 19,200, 38,400bps;
2. Does not support 7, N, 1 / 8, E, 2 / 8, O, 2 communication format;
4. Function code: 03H (read Max. 8 words in register), 06H (write 1 word into register), 01H (read Max. 16 bits of

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.
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
WARNING!
Prevent dust or metallic debris from falling into the controller that will cause malfunction.
2.
Do NOT connect to 'No Used' terminal.
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
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
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.
Make sure power cables and signals device are installed properly before power on; otherwise serious damage may
occur.
Do NOT touch the terminals or repair the controller when power on to prevent electric shock.
Wait at least one minute after power off to allow capacitors to discharge, and do not touch any internal circuit within
this period.
Do NOT touch internal terminals no matter power on or off.
For temperature accuracy, keep the controller away from heating source.

Note 1: An internal 249Ω 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 control for DTC is selective: Control output (heating, cooling), Alarm output, or Retransmission 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
control, ON/OFF control, Manual control, and PID program control.
