⑧Power supply of the instrument. If left blank, the power of the instrument is 100-240VAC. 24VDC means the
power supply of 20~32VDC or AC power (24V AC power has to be specified upon order).
POINTS TO NOTE
1. K3 module occupies two slots, OUTP and MIO. MIO cannot be used if K3 is installed. If setpoint switching feature is
required, put I2 module in COMM slot. Then set parameter bAud to 1. Two setpoints switching function can be used
in COMM instead of MIO.
2. The voltage output modules like V24, \/10 or V12 are often used for supplying power for external transducer
or feedback resistance of transmitter. These modules can be installed in any slot except that of D6 dimension
instrument. To standardize the wiring, it is recommended to be installed in the first idle slot in the order of
MIO, AUX, and COMM.
Installation and replacement of modules: Before the instrument delivery, module installation is done on request,
with corresponding parameter set correctly. Users can replace or install modules by themselves when
needed. When replacing a module, you should pull the controller out of the housing at first, insert a
small flat-tip screwdriver into the opening between the original module and the slot on motherboard to
remove the old module, and then install a new module. Changing module type needs to modify the
corresponding parameters.
Electric isolation of the modules: There are a group of 24V and a group 12V power supply built in the instrument
and isolated to the main circuit. The 24V power commonly supplies voltage output module, such as
V24/V12/V10 (24V/12V/10V voltage output module), I2 (on-off signal input module) and I4 (linear current
input module). The 12V power is commonly supplies output or communication module. Generally, the
relay contact output and TRIAC no contact discrete output are self-insulated from the other circuit, no
matter whether other modules are installed or not. SSR voltage output does not need to be insulated
from input circuit, because SSR itself has isolation function. Therefore, only the electric isolation
between the communication interface and the current output should be considered. Those modules, for
example, S (RS485 communication interface), R (RS232 communication interface) and X3 (linear current
output), all need the 12V power supply. If more than one of the above modules are installed, in order to
be electric isolated, only one of them can be module without electric isolation, the other modules should
be S4 or X4, which has its own isolated power supply. For example, if an X module is installed in OUTP
(main output) slot, and an S or X module is installed in COMM (communication interface) slot, then OUTP
and COMM cannot be electric isolated, so S or X should be replaced with S4 or X4.
No contact switch module: W1 and W2 are new types of no contact switch modules which apply the advanced
technology of “burn proof” and zero crossing conduction. It can replace the relay contact switc h.
Compared to the relay contact output module, W1 and W2 have longer life and lower interference. They

4
can largely decrease the interference spark of the equipment, and greatly improve the stability and
reliability of the system. Since the driver element is TRIAC, it is suitable for controlling 100-240VAC (not
for DC power) with current up to 80A. For the current larger than 80A, an intermediate relay is needed.
Protection elements are series wound to the output terminals, so it can control continuous current up to
0.2A with maximum allowed instantaneous current 2A.
Relay Module: The relay modules are widely used in industrial control. However, they are the only modules with
life time limit and volume limit and have much electromagnetic interference. There are four types of
relay modules: L1, L2, L3 and L4. For control output, L1 or L4 large capacity module is recommended.
L4 is equipped with high performance relay with small volume and large capacity but it costs higher. L2
module is small in size. Both of its normal open and normal close terminals have varistor spark absorption
but the capacity is small. It is suitable for alarm output. L1 and L are large in size and large capacity.
For those panel size with 48mm width (including D6, E, F and etc). large size modules cannot be installed
in both PCB board. L3 provides dual output to support two loops of alarm, for example, AL1+AL2. If
mechanical switch is not preferred or L3 is not allowed due to size limitation mentioned above, G5 (dual
SSR DC voltage output) with external SSR can be chosen.
Calibration: The instrument applies the technology of automatic zero and digital calibration, and is free of
maintenance. If the error exceeds certain range, generally, cleaning and drying the inside of the
instrument can fix it. If not, send the instrument back to the factory to examine and repair.
Warranty and maintenance: Free repair and maintenance will be given in specified period of time since the
delivery. In order to get full and correct repair, please state clear the phenomena and causes of the
malfunction of the instrument.

1.4 Rear Terminal Layout and Wiring
Wiring diagram at back side
1: For linear voltage input, if the range is
below 500mV, connect to terminals 19 and
18. 0～5V or 1～5V signal can be input
from terminals 17 and 18.
2: 4～20mA signal can be converted to 1～
5V signal by a 250 ohm resistor and input
from terminals 17 and 18. If I4 module is
installed in MIO slot, 4～20mA signal can
be input from terminals 14+ and 15- and
2-wire transmitter can be input from
terminals 16+ and 14-.
3: The compensation wires for different
kinds of thermocouple are different, and
should be directly connect to the terminals.
When the internal auto compensation
mode is used, connecting the common wire between the compensation wire and the terminals will cause measurement
error.
4: Main output from terminals 13+ 11- as current output, single channel SSR voltage output.
Wiring diagram of D size instruments (72×72mm)
1: Linear voltage signal of range below 500mV input from
terminals 13 and 12. 0～5V and 1～5V input from terminals 11
and 12.
2: 4～20mA linear current signal can be converted to 1～5V
voltage signal by connecting a 250 ohm resistor and input from
terminals 11 and 12.
3: S, S1 or S4 module can be installed in COMM slot for
communication. If relay, TRIAC no contact switch, or SSR
driver voltage output module is installed in COMM, it can be
used as AL1 alarm output. If I2 module is installed in COMM
and parameter “bAud” set to 1, then on-off signal in MIO is simulated. Setpoints SV1 and SV2 can be switched by
connecting an external mechanical switch at terminals 3 and 4.

2.1 Front Panel Description
①Upper display window, displays PV, parameter code, etc.
②Lower display window, displays SV, parameter value, or
alarm code.
③Setup key, for accessing parameter table and conforming
parameter modification.
④Data shift key, and also for auto tuning, auto/manual switch.
⑤Data decrease key, and also run/pause switch
⑥Data increase key, and also stop key
⑦LED indicator. PRG indicator is non-applicable for AI-519.
The lighting of MAN means in manual output status. MIO, OP1, OP2, AL1, AL2, AU1 and AU2 indicate I/O operation
of the corresponding module. For example, That the COMM indicator is lighting means that the instrument is
communicating with upper device.
Basic display status : When power on, the upper display window of the instrument shows the process value (PV), and
the lower window shows the setpoint (SV). This status is called basic display status. When the input signal is out of the
measurable range (for example, the thermocouple or RTD circuit is break, or input specification sets wrong), the upper
display window will alternately display “orAL” and the high limit or the low limit of PV, and the instrument will automatically
stop output. If the lower display window alternately display “HIAL”, “LoAL”, “HdAL” or “LdAL”, it means high limit alarm,
low limit alarm, deviation high alarm, and deviation low alarm happening. The alarm display can also be turned off by
setting parameter AdIS to oFF. If “EErr” is displayed, it means internal self-test error, and the instrument should be sent
back for repair.

shift of cursor. Press to direct move the cursor. Press and hold can return to the preceding parameter. The
parameter will be saved. Press (don't release) and then press key simultaneously can escape from the
parameter table. The parameter will be saved. The instrument will escape auomatically from the parameter table if no key
is pressed within 25 seconds, and the change of the last parameter will not be saved.
In Field Parameter Table, press till the last field parameter Loc appears. Setting Loc=password and then press
can access System Parameter Table.
Setpoint / Output Magnitude Switch
In the basic display status, pressing can switch lower display window between displaying setpoint or output
magnitude. If the instrument is in manual operating mode, even the lower display window is switched to setpoint display, it
will automatically return to output magnitude display after a period of time.
Setpoint (SV) Setting
If the parameter lock “Loc” isn't locked, we can set setpoint (SV) by pressing , or . The range of setpoint is
between the parameter SPL and SPH.
Auto / Manual Control Mode Switch (A/M)
When output magnitude is displayed in lower display window, pressing AT key ( ) can switch between auto-control
and manual control without bumping. If the instrument is in manual control mode and the lower display window is

the instrument can be locked at automatic or manual control mode to avoid entering manual operation by mistake.
Auto Tuning (AT)
When artificial intelligence PID control or standard PID control is chosen (CtrL=APId or nPId), the PID parameters can
be obtained by running auto-tuning. In basic display status, press for 2 seconds, the “At” parameter will appear.
Press to change the value of “At” from “oFF” to “on”, then press to active the auto-tuning process. During
auto tuning, “At” will flash at lower display window and the instrument executes on-off control. After 2 cycles of on-off
action, the instrument will obtain the values of PID control parameters. If you want to escape from auto tuning status,
press and hold for about 2 seconds until the "At" parameter appears again. Change “At” from “on” to “oFF”, press
to confirm, then the auto tuning process will be cancelled. After satisfying PID parameters are obtained, At is
recommended to be “FoFF” which prevents activating auto tuning in basic display status.
Note 1: The advanced artificial intelligence algorithm is able to avoid overshooting problem of standard PID algorithm
and achieve precise control.
Note 2: If the setpoint is different, the parameters obtained from auto-tuning are possibly different. So you’d better set
setpoint to an often-used value or middle value first, and then start auto-tuning. For the ovens with good heat
preservation, the setpoint can be set to the highest applicable temperature. It is forbidden to change SV during auto
tuning. Depending on the system, the auto-tuning time can be from several seconds to several hours.
Note 3: Parameter CHYS (on-off differential, control hysteresis) has influence on the accuracy of auto-tuning.
Generally, the smaller the value of CHYS, the higher is the precision of auto tuning. But the value of CHYS parameter
should be large enough to prevent the instrument from error action around setpoint due to the oscillation of input. CHYS
is recommended to be 2.0.
Note 4: AI series instrument has the function of self-adaptation. It is able to learn the process while working. The
control effect at the first run after auto tuning is probably not perfect, but excellent control result will be obtained after a
period of time because of self-adaptation.
3. PARAMETERS AND SETTINGS
3.1 Parameter Lock (Loc) and Field Parameters
In order to protect important parameters from being modified by mistake but also offer enough flexibility for field control,
parameter lock (Loc) and field parameters are introduced.
The parameters need to be displayed and modified in the work field are called Field Parameters. The set of field
parameters is a subset of the whole parameter set, and can be freely chosen by user.
Loc can authorize different security right as below:
Loc=0～1, allowed to modify field parameters and setpoint, and execute auto tuning;
Loc=2, allowed to modify field parameters, but can’t modify setpoint.
Loc=3～255: can only modify “Loc”
Setting Loc=PASd (Password, a number between 256 and 9999. Default is 808) and then pressing to confirm will
enter the complete parameter table and modify all parameters.
1 to 8 field parameters can be defined by parameters EP1 to EP8. If the number of the field parameters is less than 8,
the first idle EP parameter should be set to “nonE”.

CtI is recommended to be 1/4 –1/10 of derivative time. (It should be integer times of
0.5 second.)
When output type is set to relay (OPt or Aut is set to rELY), CtI will be limited to more
than 3 seconds. Auto tuning will automatically set CtI to suitable value considering
both control precision and mechanical switch longevity.

Hysteresis
CHYS is used for on-off control to avoid frequent on-off action of relay.
For a reverse acting (heating) system, when PV > SV, output turns off; when
PV<SV-CHYS, output turns on.
For a direct acting (refrigerating) system, when PV<SV, output turns off; when
PV>SV+CHYS, output turns on.

When a large value is set, the measurement input is stabilized but the response
speed is slow. Generally, it can be set to 1 to 3.
If great interference exists, then you can increase parameter “FILt” gradually to make
momentary fluctuation of measured value less than 2 to 5.

4-20: 4～20mA linear current output. X3 or X5 module should be installed in OUTP
slot.
PHA: single-phase phase-shift output. K5 module should be installed in OUTP slot.
PHA is only for 50Hz power supply, and don’t support bidirectional control system.
OPL
Output low
limit
0～100%: OPL is the minimum output of OUTP in single directional control system.
-1 ～-120%: the instrument works as a bidirectional system having
heating/refrigerating dual output. When Act=rE or rEbA, OUTP (main output) works
as heating, and AUX (Auxiliary output) works as refrigerating. When Act=dr or drbA,
OUTP works as refrigerating, and AUX works as heating.
In a bidirectional system, the heating and refrigerating ability are generally different.
OPL = -(power when AUX output is maximum /power when OUTP output is maximum)
x 100%.
For example, for a heating/refrigerating air condition, its maximum power of
refrigerating is 4000W, and maximum power of heating is 5000W, and AUX works as
refrigerating, then
OPL=- (4000/5000)x100% = -80%
The range of AUX output can’t be freely defined by user. If the internal calculation
requires maximum output of AUX (AUX output=OPL), then in 4～20mA output, the
AUX output is 20mA. User can’t limit the maximum AUX output to 10mA.

OPH
Output upper
limit
OPL limits the maximum of OUTP (main output) when PV<OEF. OPH should be
greater than OPL.
0～110%
OPrt
Soft start time
At the beginning of power on, if PV<OEF, it takes OPrt for the output value of OUTP to
rise to OPH; if PV>OEF, then the time for output value of OUTP to rise to 100% is not
more than 5 seconds. This function is only needed by special requirement.
Soft start function doesn’t affect the maximum output at auto tuning or manual control.
If it is needed to lower the impulse current of induction load, CtI=0.5 second, and
OPrt=5 second.

OEF
Work range of
OPH
When PV<OEF, the upper limit of OUTP is OPL; when PV>OEF, the upper limit of
OUTP is 100%.
For example, to avoid that the temperature raises too quickly, under 150℃, a heater
can work only under 30% of power, then we can set OEF=150.0 (℃), OPH=30 (%)

AF is used to select advanced function. The value of AF is calculated as below:
AF=Ax1 + Bx2 + Cx4 + Dx8
A=0, HdAL and LdAL work as deviation high and low limit alarms; A=1, HdAL and
LdAL work as high and low limit alarms, and the instrument can have two groups of
high and low limit alarms.
B=0, alarm and control hysteresis work as unilateral hysteresis; B=1, as bilateral
hysteresis.
For instruments with light bar, when C=0, the light bar indicates the output value;
when C=1, the light bar indicates the process value.

Additional Notes
Decimal Places
When the measuring value and all parameter value shows 0.1℃or 0.1℉during measuring temperature (depends on
parameter setting Fru), the range of parameter will become –999.0℃～+3000.0℃or –999.0℉～+3000.0℉, even the
default range is-9990～+30000. The decimal place after 999.9 will be truncated. For linear signal definition, the decimal
place are only for display. The value showing does not affect internal resolution and scale.
Alarm blocking at the beginning of power on
Some unnecessary alarms often occur at the beginning of power on. In a heating system, at the beginning of powers on,
its temperature is much lower than the setpoint. If low limit and deviation low limit are set and the alarm condition are
satisfied, the instrument should alarm, but there is no problem 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. Therefore, AI instruments
offer 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 first clears. If the alarm condition is satisfied again, the alarm will
work.
Temperature Transmitter
Besides AI PID, stand PID control and on-off control, if the output is defined as current output, the instrument can also
retransmit PV (process value) into linear current. The precision of current output is 0.2%FS, as 0.5%FS transmitter
counted whole system.
