Note 2. The value of outy determines the control mode. When it is set to:

0 - Relay J1, J2 as alarm output; SSR output disabled;

1 - Relay J1 as alarm output; J2 as PID controlled relay contact output; SSR

output disabled;

2 - Relay J1, J2 as alarm output; SSR PID control output;

3 - Relay J1, J2 as alarm output; SSR On/off control output;

4 - Relay J1 as alarm output; J2 as On/off control relay contactor output;

SSR output disabled;

5 - Relay J1 as alarm output; J2 as Limit control relay contactor output;

SSR output disabled;

6 - Relay J1, J2 as alarm output; SSR for Limit control output.

Note 3. Hysteresis Band (also called dead band, or differential), Hy, is used for

On/off control and Limit control. Its unit is in degrees (

mode, the output will be off when PV > SV and on again when PV < SV-Hy for

heating. For cooling, the output will be off when PV < SV and on again when PV >

SV + Hy. For Limit control mode, the controller cannot be reset (to turn on the

output) when PV > SV - Hy for heating, and when PV < SV + Hy for cooling.

Note 4. The Autotune offset will shift the SV value down by the Atdu value during

the Autotune process. That will prevent the system from damage due to

overheating during the Autotune.

Note 5. Calibration offset, PSb is used to set an input offset to compensate the

error produced by the sensor. For example, if the meter displays 5 ºC when probe

is in ice/water mixture, setting PSb = -5, will make the controller display 0 ºC. To

set negative value, shift to the very left digit, press down key until it shows "-".

5.2 PID Parameters (accessed by code 0036)

The PID and relevant parameters are listed in table 3. To change the parameters,

press SET key, enter code "0036", and press SET key again. The parameter flow

chart is similar to Figure 3.

The values of the P, I, and D parameters are critical for good response time,

accuracy and stability of the system. Using the Auto-tune function to automatically

determine these parameters is recommended for the first time user. If the auto-

tuning result is not satisfactory, you can manually fine-tune the PID constants for

improved performance.

Note 6. Proportional Constant (P): P is also called the proportional band. Its unit

is the percentage of the temperature range. e.g. For a K type thermocouple, the

control range is 1500° C. P=5 means the proportional band is 75° C (1500x5%).

Assuming the set temperature (SV) = 200. When integral, I, and derivative, d,

actions are removed - the controller output power will change from 100% to 0%

when temperature increases from 125 to 200° C. The smaller the P value is, the

stronger action will be for the same temperature difference between SV and PV.

Note 7. Integral time (I): Brings the system up to the set value by adding to the

output that is proportional to how far the process value (PV) is from the set value

(SV) and how long it has been there. When I decreases, the response speed is

faster but the system is less stable. When I increases, the respond speed is slower,

but the system is more stable.

Note 8. Derivative time (d): Responds to the rate of PV change, so that the

controller can compensate in advance before |SV-PV| gets too big. A larger

number increases its action. Setting d-value too small or too large would decrease

system stability, cause oscillation or even non-convergence.

Note 9. Damp constant: This constant can help the PID controller further improve

the control quality. It uses the artificial intelligence to dampen the temperature

overshot. When its value is too low, the system may overshoot. When its value is

too high, the system will be over damped.

Figure 4. Damp constant

Note 10. Cycle rate (ot): It is the time period (in seconds) that controller uses to

calculate its output. e.g. If ot=2, and controller output is set to 10%, the heater will

be on 0.2 second and off 1.8 seconds for every 2 seconds. Smaller ot result in

more precision control. For SSR output, ot is normally set at 2. For relay or

contactor output, it should be set longer to prevent contacts from wearing out too

soon. It normally set to 20~40 seconds.

Note 11. Digital Filter (Filt): Filt=0, filter disabled; Filt=1, weak filtering effect; Filt=3,

strongest filtering effect. Stronger filtering increases the stability of the readout

display, but causes more delay in the response to changes in temperature.

5.3 Temperature setting and Alarm setting (accessed by code 0001)

The temperature and alarm parameters are listed in table 4. To change the

parameters, press SET key, enter code "0001" and press SET key again. The

parameter flow chart is similar to Figure 3.
