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.
Make sure power is disconnected while checking the unit inside.
2.
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:
2
Solid/twisted wire of 2 mm , 12AWG to 24AWG. Please be sure to tighten them properly.
Do not allow dust or foreign objects to fall inside the controller to prevent it from malfunctioning.
2.
Never modify or disassemble the controller.
3.
Do not connect anything to the "No used" terminals.
4.
5. Make sure all wires are connected to the correct polarity of terminals.
Do not install and/or use the controller in places subject to:
6.
•
Dust or corrosive gases and liquid.
• High humidity and high radiation.
•
Vibration and shock.
•
High voltage and high frequency
Must turn power off when wiring and changing a temperature sensor.
7.
8. Be sure to use compensating wires that match the thermocouple types when extending or connecting the
thermocouple wires.
Please use wires with resistance when extending or connecting a platinum resistance thermometer (RTD).
9.
Please keep the wire as short as possible when wiring a platinum resistance thermometer (RTD) to the controller and
10.
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.
Please make sure power cables and signals from instruments are all installed properly before energizing the controller,
12.
otherwise serious damage may occur.
Please do not touch the terminals in the controller or try to repair the controller when power is applied to prevent an
13.
electric shock.
Wait at least one minute after power is disconnected to allow capacitors to discharge, and please do not touch any
14.
internal circuit within this period.
Do not use acid or alkaline liquids for cleaning. Please use a soft, dry cloth to clean the controller.
15.
This instrument is not furnished with a power switch or fuse. Therefore, if a fuse or power switch is required, install the
16.
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

Dual Loop Output Control (Heating/Cooling Control)
Initial Setting Mode
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
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
parameter sets an area in which the heating and cooling control
output is 0 centering around the set point in a Dual Loop output
control mode.
: Settings lock. To avoid incorrect operation, two key lock functions are provided.
settings. All parameters and temperature settings can be locked to disable changes.
except the SV (Set point) value. All parameters and temperature settings can be locked with the exception of the SV value.
Press and key simultaneously, the "Lock" status can be released.
Alarm Outputs
There are up to three groups of alarm outputs and each group allows thirteen alarm types in the initial setting mode. The
alarm output is activated whenever the process temperature value (PV) is getting higher or lower than the set point of
alarm limit.
Set Value
0 Alarm function disabled
Deviation upper- and lower-limit:
1 This alarm output operates when PV value is higher than the setting value SV+(AL-H) or
lower than the setting value SV-(AL-L).
Deviation upper-limit:
2
This alarm output operates when PV value is higher than the setting value SV+(AL-H).
Deviation lower-limit:
