6. OPERATION
Parameter Setting
At the basic display, press and hold for about 2
seconds to access Field Parameter Table. Press
to proceed to next parameter. Press , or to
modify values. Press to decrease the value.
Press to increase the value. ere is a dot ashing
while the value is changing just like a cursor. Hold
the keys will speed up the value changing speed, as
well as the ashing frequency of the cursor.
Press to move the designated digit position.
Press to save and proceed to the next parameter.
Hold to scroll down the parameter table quickly.
Press and hold more than 2 seconds goes back
to the previous parameter. Press and hold (don’t
release) plus simultaneously escape parameter
setting back to Basic Display. e instrument will
automatically escape to Basic Display if no key is
pressed for 25 seconds but any change made to the
last parameter will not be saved.
Short-cut Keys
Certain frequently used operations can be done by
short-cut keys. ose keys can be disabled.
Changing SV: Press , or to change.
Auto-tuning (AT): Press and hold for about 2 sec-
onds until “At” shows up. Press to toggle “oFF” to
“on” in the lower display. Press to start auto-tun-
ing. e lower display will ash “At”. Aer two
oscillating cycles in “ON-OFF” control mode, PID
parameters will be calculated. To quit auto-turn-
ing, perform the same operation by pressing for
2 seconds. Change “on” to “oFF” and press to
conrm to quit.
Note
1. Advanced articial intelligent technology and PID regulating algo-
rithm by AI-710JM, which is named as “APID” is able to overcome the
overshoot issue by standard PID algorithm.
2. PID values vary from dierent system. Before activating the
auto-tuning, set point value, SV, should be set at the commonly
used value or mean value. Set the SV to a maximum one if the heat
isolation of a furnace is good. SV value is not allowed to be changed
during auto-tuning. e time required for this process may takes
seconds to hours.
3. Control Hysteresis, CHYS, aects the result of auto-tuning too.
Generally the least the CHYS, the higher is the PID auto-tuning accu-
racy. However low CHYS value may cause incorrect ON-OFF output
during uctuating input. CHYS=2.0 is recommended.
4. e PID values may not give the best performance immediately
aer the auto-tuning is nished. e performance will gradually
improve over some time because there is a learning feature.
5. Regardless of auto-tuning or manual tuning, the control period, Ctl,
will be limited not longer than 3 seconds, no matter what value it is
set previously, to increase the accuracy and to provide better response
time (manual tuning).
5. DISPLAY
Basic Display
When the instrument is powered, the upper display
and lower display show the model number and rm-
ware version respectively. Aer around 3 seconds,
the displays show the process value (PV) and set
value (SV) respectively. is basic display remains
until there is a key pressed.

Filt Input Filter e value of FILt will determine the ability of ltering noise.
When a large value is set, the measurement input is stabilized but the re-

“FILt” gradually to make momentary uctuation of measured value less than
2 to 5 digits. When the instrument is being metrological veried, FILt can
be set as 0 or 1 to shorten the response time. e unit of FILt is 0.5 second.

9. Advance Function
Alarm blocking at the beginning of power on
Sometimes the fault alarm may occur at the
beginning of power on. In a heating system, at the
beginning of power on, its temperature is much low-
er than the set point. If low limit and deviation low
limit are set and the alarm conditions are satised,
the instrument should alarm, but there is no prob-
lem in the system. Contrarily, in an refrigerating
system, the unnecessary high limit or deviation high
limit alarm may occur at the beginning of power
on. erefore, AI instruments oer the function of
alarm blocking at the beginning of power on. When
Act is set to rEbA or drbA, the corresponding low
or high alarms are blocked until the alarm condition
rst clears. If the alarm condition is satised again,
the alarm will work.
Communication function
S or S4 module can be installed at COMM slot to
communicate with a computer. e instrument can
be controlled by computer. AI instruments can be
connected to the computer through RS232 or USB
communication port. Every communication port of
a computer can connect up to 60 AI instruments,
or 80 AI instruments if a repeater is installed. A
computer with 2 communication ports can connect
up to 160 instruments. Please note that every instru-
ment connecting to the same communication line
should be set to a unique communication address.
If the number of instrument are enough, 2 or more
computers can be used and a local network can be
set up.
If users want to develop their own distributed
control system by themselves, the communication
protocol of AI instruments can be freely oered.
ere are many distributed control system soware
support AI instruments.
Fine control
Fine control means that the PID operating reso-
lution is ten times as high as the display resolu-
tion. For example, the temperature signal of the
instrument displays 1°C, but the internal PID still
operate and control as per 0.1°C resolution, thus can
realize the control accuracy much higher than the
display resolution. In former AI series instruments,
only temperature signal adopts ne control mode.
e new edition approves default ne control mode
when the displayed value range is below 3,000 char-
acters (on most of industrial application occasions,
the value should not exceed 3,000 characters) during
linear input, so as to get higher control accuracy and
more stable output. When the required display value
range is larger than 3,000, AF.F=1.
User-defined input specifications
When INP is set to 64 larger than preset value, the
input specication of the instrument switches to
user-dened input. Set INP=22+64=86. e linear
table can be edited, the setup method is as follows:
set Loc parameter as 3698, and then enter the table
setup status (if the original Loc=808, the Loc shall
be zeroed, exit the parameter setting status, and then
reenter the parameter setting status and set Loc as
3698). Of which the parameter A 00 denes the use
of the table, 0 is used to input non-linear measuring,
1 is used to high temperature furnace non-linear
control, with parameters of A01~A04 and d00~d60
respectively set as follows:
A 00=0 (xed)
A 01 denes input speccation
Formula: A 01=A*1+E*16+G×*64
A is the range of measurement:
A=0: 0~20mV (0-80Ω);
A=1: 0~60mV (0-240Ω);
A=2: 0~100mV (0-400Ω);
A=3: 0~1V;
A=4: 0~5V,
A=10, 0~20mA or 0~10V (MIO position installed with I4 or I31
module)
E=0: Output value still should be determined as per ScH/ScL parame-
ters during linear input of signals.
E=1: e table output value is the displayed value.
G is the type of sensor.
G=0: thermocouple;
G=1: thermal resistance;
G=2: linear voltage (current);
G=3: linear resistance
For instance: Pt100 input; range 30~40oC; every adjustment section
at one degree

A04 = 10.0
d00 = 30.00 d01 = 31.00 d02 = 32.00
d03 = 33.00 d04 = 34.00 d05 = 35.00
d06 = 36.00 d07 = 37.00 d08 = 38.00
d09 = 39.00 d10 = 40.00
Set the deivation directly to the particular temperature. If it is show-
ing 37oC but it is found higher, set d07 a little bit lower than 37.00.
