2. Prevent dust or metallic debris from falling into the device and cause malfunction. DO NOT modify or uninstall DTV 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 DTV 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. DTV 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. DO NOT touch the internal wiring within this period.
12. DO use dry cloth and DONOT use acid or alkaline liquid to clean the device.

PID Programmable Control
Functions and Parameter Setting:
The PID programmable control includes 8 patterns (Pattern 0 ~ 7). Each pattern contains 8 steps (Step 0 ~ 7) and parameters: link pattern, cycle and the
number of steps.
Start Pattern
: This parameter can be set in the operation mode. The user can set up which pattern is the start pattern for the programmable control.
This function is only available when the program is in STOP status.
Step: Includes the settings of the two parameters, set point X and execution time T, indicating that the set point (SV) has to rise to temperature X after the
period of execution time T. If the result of the set point X is the same as that of the previous setting, the process is called Soak; otherwise, it is called Ramp.
Therefore, the programmable control is also known as Ramp/Soak control.
The default setting of the first step program is Soak control. The temperature will first rise to the set point X and remain at X. The total execution time is T.
Link Pattern: For example, if the parameter
is set as
is set as 2, it refers to the execution of pattern 2 will follow the execution of pattern 0. If the link pattern
, it refers to the program will end after the execution of the pattern is completed and the temperature will remain at the SV for the last step.
Cycle: The additional number of cycles for a pattern. For example, if the parameter
additionally, totaling the executions to 3 times including the original one.
is set as 2, it refers to pattern 4 has to execute twice

The Number of Steps: The number of steps in each pattern (range: 0 ~ 7). For example, if the parameter
execute step 0 ~ step 2 and other steps will not be executed.
is set as 2, it refers to pattern 7 will
The Execution:

is set as
2. When the parameter
is set as

3. When the parameter
is set as

, the program will start its execution from step 0 of the start pattern.
again, the program will execute again from step 0 of the start pattern.
4. When the parameter
is set as
, the program will stop and the temperature will stop at the SV before the program stops. When you select
again, the program will resume the step before the program stops and execute by the remaining time.


Valve Control
Heaters and coolers can be used to control the temperature and the openness of the valve in order to control the flow of the medium. Current and voltage
can control the openness of the valve; however, the most direct and economic way to control the openness of the valve is the relay. To control the valve by
voltage and current, you can use the DTB series analog output controller. If you tend to use relay for the control output, you have to choose the valve
function in DTV series. The two control outputs are relay output for the forward/reverse running of the motor to drive the opening and closing of the valve.
Control output1 controls the opening of the valve and control output 2 controls the closing of the valve in order to adjust the position of the valve. In order to
detect the position of the valve, DTV is able to receive “feedback signal” and “no feedback signal”. When there is no feedback signal and the valve is fully
open, control output 1 will output continuously. If at the moment the valve is fully closed, control output 2 will output continuously. If the valve you use is with
feedback output, you can connect the output of the valve to the feedback part of DTV and set
to On to precisely control the openness of the valve. If
there is no feedback signal or the feedback signal is incorrect, and the pre-set openness of the valve is not reached after twice as long as the time set in the
, the program will automatically switch back to the no feedback state. To ensure the correctness of the valve control, please make sure
parameter
that you have set up the parameters below:
: Time required from the valve fully closed to fully open. This parameter has to be correct when the valve is without feedback signal; otherwise, the
accuracy for the temperature control will be affected. The PID control will correspond to the openness of the valve according to the setting of this parameter.
: DeadBand value of the valve. The parameter is to prevent frequent movement of the valve. For example, assume the DeadBand is 4%, PID control
will correspond to the openness of the valve within 4% and the valve will not move within the range unless the value is accumulated and exceeds 4%. If the
Deadband value is too small and the valve is set to have feedback signals, moving back and forth of the valve will shorten the life of the valve motor.
: With or without feedback signals.
When
a)
is set as “On”, it refers to “with feedback signals” and the following parameters will be displayed.
: Automatically adjusting the upper/lower limit of the valve feedback. This parameter will only be displayed when
is set as
. When
this parameter is set as On, the relay will enable the forward and reverse running of the motor in order to calculate the time needed from the valve fully
closed to fully open and the feedback signal of fully closed and open. The feedback signal is the hardware D/A value of the valve control, which is for the
calculation of the valve controller.
b)
: Upper limit of the valve signal. Set
as “On”, can be set automatically or manually.
c)
: Lower limit of the valve signal. Set
as ”On”, can be set automatically or manually.

Auto/Manual Mode Switch
A/M indicator On refers to manual mode; A/M indicator Off refers to auto mode. Besides On/Off, PID, programmable and manual controls, the valve control
is also able to forcibly switch to manual control (fixing the openness of the valve, unit: % from valve fully closed to fully open) when in PID control mode. You
simply need to press
in PID control mode to switch to manual mode and A/M indicator will be On. Press
again to return to PID control and A/M
indicator will be Off.

Upper/Lower Limits of Valve Openness
Assume we would like the maximum openness of the valve to be 80% and the minimum to be 20%, set the parameter
and the valve openness of PID control, programmable control and manual control will fall within this range.

CRC (Cyclical Redundancy Check) is obtained by the following steps.
1. Load in a 16-bit register FFFFH as the CRC register.
2. Do an exclusive OR operation of the first byte of the data and low byte of CRC register, and place the operation result back to the CRC register.
3. Right shift the bits in the CRC register and fill the high bits with “0”. Check the removed lowest bit.
4. If the removed lowest bit is “0”, repeat step 3. Otherwise, do an exclusive OR operation of the CRC register and the value A001H and place the operation
result back to the CRC register.
5. Repeat step 3 and 4 until the 8 bits (1 byte) are all right shifted.
6. Repeat step 2 and 5 and calcualte all the bits to obtain CRC check.
Please be aware of the high/low byte transmission order in the CRC register.
