III. FRONT PANEL AND OPERATION
① Process Value(PV), or parameter code
② Set Value(SV), alarming code, or value of a parameter
③ Setup key, accessing parameter table, and confirming change.
④ Data shift key, also for activating auto turning
⑤ Data decrease key
⑥ Data increase key
⑦ Status display LED,
OP1 – Output
AU1 – Alarm 1
AU2 – Alarm 2
RUN – Controlling process running
Default display status:
When power is on, the process value (PV) and the set value (SV) are shown. lf the input signal is out of the measurable range (for example,
the thermocouple or RTD circuit is break or input specification is not correctly set), the upper display will blink “orA” and high limit or low
limit of specified input. The instrument will automatically stop the output.
IV. OPERATION DESCRIPTION
● Set Value Setting:
During default display status, if the parameter lock “Loc” isn't locked, user can set setpoint (SV) by pressing YVUkeys. Press V
key to decrease the value, Ukey to increase the value, and Ykey to move to the dot to the desiired digit (acting as a pointer). Keep
pressing Vor Uwill speed up value change. The range of setpoint is limited by parameter SPH with default range 0 to 400.
●Parameter Setting:
During default display status, press and hold 3for 2 seconds will access Field Parameter Table (See V. PARAMETER AND
SETTING). Press 3to proceed to the next parameter. If parameter table have not been locked, press YVUwill change the
parameter. Press and hold Yfor 2 second returns to the preceding parameter. Press Y(don't release) and then press 3
simultaneously jumps out from parameter setting to the default status. The instrument will also jumps out auomatically from the
parameter table if no key is pressed in 30 seconds. Setting Loc=808 and then press 3will access System Parameter Table (See V.
PARAMETER AND SETTING)
●AI artificial intelligence control and auto tuning
When AI artificial intelligence control algorithm is selected (CrL=AI), the P,I, and D parameters can be calculated automatically by
auto-tuning. In default display status, press and hold Yfor 2 seconds, “At” auto-tuning parameter will show. Press Uto change the
value of “At” from “oFF” to “on”, then press 3to activate the auto-tuning. During auto-tuning, the instrument runs on-off control for two
cycles. The instrument will calculate the optimal P, I and D control parameter values and returns to default display. If user want to
interrupt the auto tuning process, press and hold the Yfor 2 seconds. Change “At” from “on” to “oFF” and press 3to confirm. The
auto-tuning process will be cancelled and new P, I and D values will be calculated.
Note 1: The P, I and D parameters obtained from auto-tuning are dependent to the set value. It is recommended to set a set value to an
often-used value or mean value to perform auto-tuning. For the ovens with good heat preservation, the set value can be set at
the highest applicable temperature. Depending on hardware setup, the auto-tuning may take from a few seconds to a few hours.
Note 2: Parameter Ctl (on-off differential, control hysteresis) has influence on the accuracy of auto-tuning. Generally, the smaller the
value of Ctl, the higher the precision of auto tuning. But Ctl parameter value should be large enough to prevent the instrument
from error action around set value due to the oscillation of input. Ctl is recommended to be 2.0.
Note 3: Self-learning function enables the instrument to control better and better after time.

stops. When PV<SV-AHY, output resumes.
zAI : AI-PID control. The output time proportion can adjusted by
parameter Ctl

rE: Reverse acting. Increase in measured variable causes a decrease
in the output, such as heating control.
dr: Direct acting. Increase in measured variable causes an increase in
the output, such as refrigerating control.

blocking at the beginning of power on.

Ctl Control period
Smaller value will result in higher control accuracy.
For SSR output, generally 0.5 to 3 seconds.
For Relay output, generally 15 to 40 seconds, because small value will
cause the frequent On-Off of mechanical switch and shorten its service
life. Ctl is recommended to be 1/4 – 1/10 of derivative time. When
control under on-off control, Ctl is used as delay time to restart to
protect the compressor.

Higher degree of FIL gives more powerful noise filtering.
Large FIL value stabilized the input signal but the system response
speed will be slow. Generally speaking, 1 to 3 will be used.
If great interference exists, FIL can be gradually increase to limit the
momentary fluctuation among 2 to 5 unit.
When the instrument is being metrological verified, FIL should be set to
0 or 1 to minimize the response time.
