 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 is equipped with protective methods such as some special tool or key to open the enclosure, so as 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) 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.

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 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:

parameter appear in

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

execution of pattern No. 0. If set to the temperature will keep at the set point of the last step.

Cycle Parameter: Additional execution cycle number. For example, when set 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 indicates that pattern No 7 will not execute other steps than step 0 to step2.

Execution: When

before program hold. Select through the rest of the time.

Retransmission Output:

When the 1

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.

Alarm Output:

This controller provides twelve types of alarm input selections. When PV is higher or lower than SV, alarm output will act. Following table consists of twelve alarm output modes.

 LED Display

1. When power is normal, POWER LED will be lit.

2. LED will be lit after power on. Within one second after power on, communication protocol will be displayed; and at the following second after communication protocol displayed, communication address will be displayed. After that, LED will all be lit to show operation is normal.

3. When control action is executing, RUN LED will be lit.

4. When input, memory, or communication happens to error, ERROR LED will be lit.

5. When output is acted, the corresponding LED will be lit.

6. When PID program is auto adjusting parameter, AT LED will blink.

7. RX LED will blink when receiving communication signal and TX LED will blink when transmitting communication signal.

Protocol Format of LED Display When Power On

AT TX RX O1 O2 Err Run 000: 2,400bps 001: 4,800bps 010: 9,600bps 011: 19,200bps 100: 38,400bps

0: ASCII 1: RTU

0:2 Stop bit 1:1 Stop bit

Communication address display: AT (bit 6) and Run (bit 0) will combine to binary code.

 Password Function

The default of password will not operate. After writing 4-byte password into specific communication address, password function will be activated. There are three levels for password protection:

1. Level1: only LED status, settings, and input values can be read via communication. It is unable to revise anything.

2. Level2: only LED status, settings, and input value can be read via communication. Also, it is able to revise setting.

3. Level3: all the settings can be read via communication, but it is only revisable for settings and AT adjustment.

4. No password function. Once password is set (106EH ~ 1070H), the controller will enter level 1. For entering another level, please key in corresponding password in 106BH ~ 106DH (see Address and content of Data Register). After power off, it will get back to level one. If password protection function shall be dismissed, it is necessary to clear all password setting. To enable password function, it is necessary to write corresponding password (106EH ~ 1070H) when password status is dismissed. To dismiss password levels, intended password setting should be written in specific function address 106EH ~ 1070H.

Password status can be read from 106EH~1070H. Statuses corresponding to each bit are shown as the following table:

Bit b0 b1 b2 b3 b4 b5 b6

Status Level 1 Level 2 Level 3 Level 1 locked Level 2 locked Level 3 locked Unlock Bit = 0 means no password setting. Bit = 1 means password is set (b0 ~ b2). b3 ~ b6 are used for displaying current password status.

 Synchronous Communication Protocol & Auto Number ID

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. After that, switch on the power again.

3. Communication default: 9600bps, 7bits, Even, 1 stop bit.

4. This function will result in additional 3~5 seconds for power on.

 RS-485 Communication

1. Supporting transmission speed: 2,400, 4,800, 9,600, 19,200, 38,400bps.

2. Non-supported formats: 7, N, 1 or 8, E, 2 or 8, O, 2.

3. Communication protocol: Modbus (ASCII or RTU)

4. Function code: 03H to read the content of register (max. 8 words). 06H to write one word into register. 01H to read

bits data (max. 16 bits). 05H to write one bit to register.

LRC Check:

LRC check is the added sum from “Machine Address” to “Data content”. For example, 01H + 03H + 10H+ 00H + 00H + 02H = 16H, then take the complementary of 2 to get EA.

Following is a CRC (Cyclical Redundancy Check) program example:

unsigned int reg_crc = 0xffff; i = 0; while (length--) { reg_crc ^= RTUData[i]; i ++; for (j = 0; j < 8; j++) { if (reg_crc & 0x01) reg_crc = (reg_crc >> 1) ^ 0xA001; else reg_crc = reg_crc >> 1; } } return(reg_crc);
