Series Temperature Controller Instruction Sheet
Thank you very much for choosing Delta DTD series temperature controller. Please read this instruction sheet before using your DTD to ensure proper operation. Keep this instruction sheet handy for quick reference.
Warning
DANGER! CAUTION! ELECTRIC SHOCK! When the power is on, DO NOT touch the AC terminals in case an electric shock may occur. Make sure
the power is disconnected when you check the input power.
DTD is an OPEN-TYPE device. If it will cause serious injury to workers or damage on other equipments when used in a dangerous environment, please make sure it is installed in an automatic safety protection device.
1.Always use recommended solder-less terminals: Fork terminal with isolation (M3 screw, Max. width 7.2mm). Please be sure to tighten them properly and make sure the wire is connected to the correct terminal.
2.Prevent dust or metallic debris from falling into the device and cause malfunctions. DO NOT modify or uninstall DTD series without being permitted. DO NOT use empty terminals.
3.Keep away from high-voltage and high-frequency environment during installation in case of interference. Prevent using the device in premises which contain:
(a)dust or corrosive gas; (b) high humidity and high radiation; (c) shock and vibration
4.The power has to be switched off when wiring or changing temperature sensor.
5.Make sure to use compensation wire which matches the thermocouple when extending or connecting the thermocouple wire.
6.Use wires with resistance when extending or connecting the platinum resistance sensor.
7.Keep the wire as short as possible when wiring a sensor to the temperature controller. Separate the power cable and load wire in order to prevent interference and induced noise.
8.DTD is an open-type device. Make sure to install it in an enclosure which prevents dust and humidity in case of an electric shock.
9.Make sure the power cables and signal device are installed correctly before switching on the power; otherwise serious damage may occur.
10.DO NOT touch the terminals or repair the device when the power is on; otherwise an electric shock may occur
11.Please wait for one minute after the power is switched off to allow the capacitor to discharge and DO NOT touch the internal wiring within this period. Use dry cloth to clean the device. DO NOT use acid or alkaline liquid to clean the device.

Operation Instructions on Keys!
Switching Modes
DTD is in operation mode (the first level) when the power is switched on. Press 
once to switch to the regulation mode (the second
level), or press 
for more than 3 seconds in operation mode to switch to the initial setting mode (the third level). Press 
once in other screens to return to the operation mode.
Switching Functions
Press 
in each mode to select functions. Press 
once to switch to the next function, or return to the first function when press 
in the last function.
Modifying Settings
Select the item to be set up by using 
and 
. Next, press 
. If the item to be set up is a value, the last digit of the SV will flash. If you press 
to select parameters, the SV will flash. Press 
to increase the value of the digit or select parameters. When setting up the value, press 
to left shift to the digit to be modified.
Examples
1.DTD from STOP to RUN: Press 
once and select parameter 
. SV will display 
. Press 
and 
will flash. Press 
to save the setting and 
will stop flashing.
2.Modifying SV from 80 to 120: Press 
and display 0080 (the last digit in right hand side 0 will flash). Press 
once and 8 will flash. Next, press 
4 times and “2” in the display 0020 will flash. Press 
once and the 100s digit 0 will flash. Press 
once and ”1” in the display 0120 will flash. Press 
to complete and save the setting.
Input Settings!
Setting up Input Type
When DTD is switched on, SV will display the type of the input sensor (default K1 = thermocouple type). Press 
for more than 3 seconds in the operation mode and PV will display the parameter 
. Press 
to select the sensor types (see the table below) and press 
to complete and save the setting. The screen will return to the screen of operation mode.
If the setting is current input, a 249Ω resistor has to be connected to the current input terminals.
Setting up Input Unit
In the operation mode, press 
for more than 3 seconds and PV will display the parameter 
. Press 
once to select the
unit. If the input type is thermocouple or platinum resistance, the PV will display 
. In this case, press 
to select the temperature unit (°C or °F). If the input type is an analog input, the PV will display 
. In this case, you can set up the position of the decimal point
for the analog input. Press 
to complete and save the setting.
Setting up Input Range
After you complete setting up the input unit, press 
once to display the parameter 
. Use 
and 
to set the maximum
value for the temperature range. Press 
again to display the parameter 
, and use 
and 
to set the minimum value for the temperature range. The default range is the maximum range measurable (see the table below) and both parameters cannot exceed this range. When PV exceeds the range, PV will flash and DTD will stop its operation.
When in analog input, the temperature range also refers to the maximum and minimum input values. For example, when 4 ~20mA input is adopted, 
= 2,000, 
= 400. That is to say, PV = 1,200 refers to the input is 12mA and the unit is 0.01mA.
Adjusting Input Inaccuracy
When there is the need to correct the measured input PV, press 
once in the operation mode to enter the regulation mode. Press 
repeatedly until the parameter of input compensation value 
appears. Modifying this parameter will make the PV = measured value + input compensation value. Press 
again to display the parameter of input gain 
and make PV = measured value × (1 +
input gain/1,000) + input compensation value. Press |
again and display the parameter of software filter (default = 2). |
||
Increase this parameter to enhance the stability of the PV; however, this will result in slow reaction to the input value. |

Control Settings!
Setting up Control Mode
In the operation mode, press 
for more than 3 seconds and PV will display the parameter 
. Press 
for 4 times to display the parameter 
. The default setting of this parameter is “On/Off control” 
. Use 
to select PID control 
, PID programmable control 
or manual control 
. Press 
again and display the parameter 
for selecting the control method. You can select heading (default) 
or cooling 
. Press 
to return to the operation mode.
Setting up RUN and STOP
In the operation mode, press 
and display parameter 
. The default is RUN 
. Use 
to select STOP 
. Press 
to complete the setting and the output will be disabled.
Setting up On/Off Control Parameters
Press 
in the operation mode. If DTD is in On/Off heating mode, the PV will display 
; if in On/Off cooling mode, the PV will display 
. Modify these parameters to set up the hysteresis of On/Off. The default setting is 0 (without hysteresis). When the output reaches SV, the control output will be disabled. When the input is bigger (cooling) or smaller (heating) than the SV and hysteresis, the control output will be enabled. When the On/Off hysteresis is not 0, the control output will be like the diagrams below.

Setting up PID Parameters
When in PID control mode, you have to first decide the On/Off cycle time for the control output, i.e. the control cycle. Press 
in the
operation mode and PV will display 
. Press 
5 times to display the parameters of heating control cycle 
or cooling control cycle 
. Set up the cycle depending on the reaction speed of the control system. In principle, the faster the reaction, the shorter the cycle and more accurate the control. A short control cycle indicates that there will be more times of On/Off. If you adopt relay output, the short cycle will shorten the life span of the relay. Therefore, it is recommended that you adopt voltage output in the PID control mode. The default setting of the control cycle is 20 seconds.
