Series Temperature Controller

 

Instruction Sheet

 

Thank you very much for purchasing DELTA B Series. Please read this instruction sheet before using your B series to 

ensure proper operation and please keep this instruction sheet handy for quick reference. 

 

 

Precautions

 

 

DANGER! Caution! Electric Shock!

 

1. 

Do not touch the AC terminals while the power is supplied to the controller to prevent an electric shock. 

2. 

Make sure power is disconnected while checking the unit inside. 

3. 

The symbol 

  indicates that this Delta B Series Temperature Controller is protected throughout by DOUBLE 

INSULATION or REINFORCED INSULATION (equivalent to Class II of IEC 536).

 

 

WARNING!

 

This controller is an open-type temperature controller. Make sure to evaluate any dangerous application in which 
a serious human injury or serious property damage may occur. 

1. 

Always use recommended solder-less terminals: Fork terminal with isolation (M3 screw, width is 7.0mm (6.0mm for 

DTB 4824), hole diameter 3.2mm). Screw size: M3 x 6.5 (With 6.8 x 6.8 square washer). Screw size for DTB4824: M3 

x 4.5 (With 6.0 x 6.0 square washer). Recommended tightening torque: 0.4 N.m (4kgf.cm). Applicable wire: 

Solid/twisted wire of 2 mm

2

, 12AWG to 24AWG. Please be sure to tighten them properly. 

2. 

Do not allow dust or foreign objects to fall inside the controller to prevent it from malfunctioning. 

3. 

Never modify or disassemble the controller. 

4. 

Do not connect anything to the “No used” terminals. 

5. 

Make sure all wires are connected to the correct polarity of terminals. 

6. 

Do not install and/or use the controller in places subject to: 

  Dust or corrosive gases and liquid. 

  High humidity and high radiation. 

  Vibration and shock. 

  High voltage and high frequency 

7. 

Must turn power off when wiring and changing a temperature sensor. 

8. 

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

thermocouple wires. 

9. 

Please use wires with resistance when extending or connecting a platinum resistance thermometer (RTD). 

10. 

Please keep the wire as short as possible when wiring a platinum resistance thermometer (RTD) to the controller and 

please route power wires as far as possible from load wires to prevent interference and induced noise. 

11. 

This controller is an open-type unit and must be placed in an enclosure away from high temperature, humidity, dripping 

water, corrosive materials, airborne dust and electric shock or vibration. 

12. 

Please make sure power cables and signals from instruments are all installed properly before energizing the controller, 

otherwise serious damage may occur. 

13. 

Please do not touch the terminals in the controller or try to repair the controller when power is applied to prevent an 

electric shock. 

14. 

Wait at least one minute after power is disconnected to allow capacitors to discharge, and please do not touch any 

internal circuit within this period. 

15. 

Do not use acid or alkaline liquids for cleaning. Please use a soft, dry cloth to clean the controller. 

16. 

This instrument is not furnished with a power switch or fuse. Therefore, if a fuse or power switch is required, install the 

protection close to the instrument. Recommended fuse rating: Rated voltage 250 V, Rated current 1 A. Fuse type: 

Time-lag fuse 

17. 

Note: This controller does not provide overcurrent protection. Use of this product requires that suitable overcurrent 

protection device(s) must be added to ensure compliance with all relevant electrical standards and codes. (Rated 250 

V, 15 Amps max). A suitable disconnecting device should be provided near the controller in the end-use installation.

Note 2:

  (Operation mode) must be set if user wish to specify decimal point position. Except for the thermocouple B, S, R type, the decimal point positions of all 

the other thermocouple type input sensors can be set. 
The default range of analog input is -999 ~ 9999. For example, when a 0 ~ 20mA analog input is selected as the input temperature sensor type, -999 indicates 0mA and 
9999 indicates 20mA. If change the input range to 0 ~ 2000, then 0 indicates 0mA and 2000 indicates 20mA. One display scale is equal to 0.01mA. 

 

 

Operation

 

There are three modes of operation: operation, regulation and initial setting. When power is applied, controller gets into 
the operation mode. Press the 

  key to switch to regulation mode. If the 

  key is pressed for more than 3 seconds, 

controller will switch to the initial setting mode. Pressing the 

  key while in the regulation mode or initial setting mode, 

forces the controller to return to the operation mode. PV/SV: Sets the temperature set point and displays the temperature 
process value. Use 

  keys to set the temperature set point. 

Setting method: While in any function mode, press the 

  key to select the desired function and use the 

 keys to 

change settings. Press 

  key to save the changes. The next flow chart shows how to switch for settings and internal

Temperature control can be achieved either by heating or cooling. In 
DTB series, heating and cooling can be operated simultaneously 
(Dual Loop output control) to perform temperature control. When Dual 
Loop output control are used, two control outputs must be connected 
to the heating and cooling devices. Please refer to the following for 
the operation: 

  : This parameter is used to select heating or cooling action if 

operate either heating or cooling function in this controller. When 
selecting 

, 1st output group is heating (reverse) control, and 

when selecting 

, 1st output group is cooling (forward) control. 

At this moment, 2nd output group is regarded as an alarm output. If 
user select 

 or

, it indicates that user can operate Dual 

Loop output control function in this controller. When selecting 

1st output group is heating (reverse) control and 2nd output group is 
cooling (forward) control. When selecting 

, 1st output group is 

cooling (forward) control and 2nd output group is heating (reverse) 
control. 
 
In DTB series, P (Proportional Band), I(Integral Time) and 
D(Derivative Time) parameters are automatically set by using the 
Auto-tuning (AT) function. 

  : This parameter is for the control mode that must be Dual 

Loop output control with PID control method configured. The value of 
P, I and D of 1st output group can be set immediately. The P value of 
2nd output group is equal to (P value of 1st output group) x 

 

and the value of I and D of 2nd output group are the same as the 
value of I and D of 1st output group. 

  : Dead Band, shown as the following figure 1, 2 and 3. This

Alarm Outputs

 

There are up to three groups of alarm outputs and each group allows thirteen alarm types in the initial setting mode. The
