Thermocouple wiring:
When wiring a thermocouple input, the compensation wire should be qualified and directly connect to the
corresponding terminals in correct direction. When M1 module is installed in J1 socket, a Cu50 resistor can
be connected between terminal 17 and 20 to compensate the cold junction; short terminal 17 and 20 to have
ice-point compensation.
AI-702M/704M/706M can measure the lead wire resistance of two-wire method and save it to parameter “Sc”.
However, the lead wire resistance changes as the temperature changes. If the lead wires has the same
ambient temperature as that of the instrument and no other resistor series connects to the lead wire, the
indicators can compensate the resistance change by measuring the ambient temperature (compensation
coefficient is 0.004/℃); otherwise, two-wire method is not recommended.
15
Three-wire RTD wiring:
Three-wire method is a traditional wiring method requiring that the resistance of the three wires be equal. One
“J0” module supports 1 three-wire RTD. Three-wire method provides higher measurement accuracy.
Maximum 3 channel of three-wire RTD is accepted. The channel number automatically shifts forward,
affecting the parameter application. E.g. J0 module is installed in M1 and M2 slot for two three-wire RTD. J2
module is installed in M3. This implies the instrument accept four channels (Parameter: Cn=4, AF.B=1). There
is no IN5 and IN6. Three-wired RTD is recommended to install in prior slot to avoid confusion.

Press to display next channel, and press to display previous channel. Press can switch
between auto cyclic display and manual display.
2. Parameter setting:
When the parameter lock is unlocked, press and hold for about 2 seconds until parameter is
displayed. At this moment, press in short; all parameters will be displayed one by one. When the
parameters are set and the parameter lock is locked, press can access Field Parameter Table.
The value of a parameter can be modified by , or . Press to go to next parameter.
Press and hold can return to the previous parameter. Press + can exit parameter
setting status.
18
3. Alarm display:
The lower display window shows channel number. If high or low alarm occurs, the first digit from the left
of lower display window will show “H” or “L”, and flickers, and if over range occurs (for example, wire
broken for thermocouple input), the upper display window will show high or low limit valve, and the lower
display window flickers.
If only 2 input channels configured, then the upper and lower display window will show
the input values of channel 1 and 2 respectively. When over range occurs, the corresponding display
window will flickers.
Lead wire resistance compensation for 2-wire RTD input:
Offset value (parameter “Sc”) need to be set to counteract lead wire resistance for 2-wire type RTD like
Pt100 or Cu50. This offset value can be set automatically by the following procedures:
1. Short connect 2 wiring terminals on the RTD sensor side
2. Set parameter “Loc” to 808, and then press until “A” appears on the first digit of lower display
window.
3. Wait until “A” disappears, and then removes the short wire, and set “Loc” to 0 or 1.
4. Now, the instrument comes back to normal measurement display mode, and the setting of
parameter “Sc” is finished.
19
The unit of Sc is 1/20000 of the scale of the corresponding RTD. At 0℃, the total resistance of the two lead
wire of Pt100 or 0~400ohm should be less than 4ohm, and that of Cu50 should be less than 2ohm.
Otherwise, wire resistant compensation will not function. The smaller the resistance of the lead wire, can
provide more accurate measurement.
20
4. DIN rail mounted type
DIN mounted type (dimension E5) has no display window. It can input analog signals or input/output on-off
signals for host computer or PLC, and it can also work as a two-channel programmable re-transmitter.
E5 dimension instrument has one LED indication light. When the instrument is communicating with the host
computer, the light flashes with light on time different to light off time. When the instrument hasn’t received
signal from the host computer for 6 seconds, the indication light should flash with the same light on time and
light off time.
It means:
That the on-off period is as long as 1.6 second means no communication and no alarm (it can be treated
as normal);
The light flashing with period 0.6 second means no communication and general error occurs.
The light quickly flashing with period 0.3 second means no communication and severe error such as
input over range occurs.
The light keeping off means the instrument power off or damaged; the light keep on (longer than 8
seconds) means the instrument power on but damaged.
21
The parameters of E5 dimension instrument can be set by connecting external display to the 1394 socket.
Note: The 1394 socket of the instrument only supports Yudian external display.
The instrument can connect PC or PLC to monitoring or capture the data. We can provide the FREE protocol
for user or order our monitoring software-AIDCS. Please contact Yudian Sales Dept. for more detail.
By connecting 2 units of three-wire PT100 input, is can become the dry bulb, wet bulb humidity measurement.
1. Install J0 (RTD input module) in both M1 and M2 slot. Set Sn1=22, Sn2=42.
2. Atmospheric pressure and wind speed defined by parameter “Po” and “SPEd”
3. Initialize measurement by wrapping dry bulb with wet muslin, giving same condition with wet bulb
4. Once reading is stable, adjust parameter Sc2 to offset reading to 100%,
5. Remove wet muslin after the adjustment.
6. Recommended to set parameter (dIP1=1, dIP2=0) to have more stable reading with resolution 0.1 ℃
and 1%RH.

dIPx is set to select display resolution for channel x.
Linear input: display resolution of dIP=0,1,2,3 are 0, 0.0,
0.00 and 0.000
Decimal point Thermocouple or RTD inputs: when dIP=0, the display
dIPx 0~3
position resolution is 1℃; when dIP=1, the resolution is 0.1℃.
Note: dIP only affects the display, and has no effect on
internal data. Resolution becomes 1℃ when over 1000℃.
26
The input of 1V indicates the pressure=0MPa, and 5V
indicates the pressure=1MPa, and expected display
resolution is 0.001MPa. Then the parameters should be
dIHx Scale high limit set as below:
Sn1=33, dIP1=3, dIL1=0.000, dIH1=1.000
27
The value of dF will determine the ability of filtering noise.
dL=0, no filtering;
dL=1, filtering with mean;
dL=2~40, filtering with mean and integral.
When a large value is set, the measurement input is
stabilized but the response speed is slow. Generally, it
dLx Digital filter 0~40
can be set to 1 to 3.
If great interference exists, you can increase parameter dF
gradually to make momentary fluctuation of measured
value less than 2 to 5.
When the instrument is being metrological verified, dF can
be set to 0 or 1 to shorten the response time.
28
From right side to left side, the first, second digit of AOP
respectively indicate the alarm output assignment of H.AL,
L.AL, as below:

For example:
ALP1=43, low limit alarm (L.AL) of channel 1 output to AL2,
ALP2=53, low limit alarm (L.AL) of channel 2 output to AU1,
and both high limit alarms(H.AL) of both channel are sent to
AL1.

is calculated as below:
AF=Ax1 + Bx2 + Cx4 + Dx8 + Ex16

For example, to transmit the channel 1 input 0~600℃ into

Every instrument in the same communication line should
be assigned to different communication address. The
Communication communication applies AIBUS protocol. Every input
Addr 0 ~100
address channel takes one address. For example, if Cn=3 and
Addr=10, then the communication address 10~12 are
assigned to the instrument.
When COMM module interface is used for communication,
bAud defines the baud rate with range 300~19200bit/s.
bAud Baud rate When linear current output module is installed in COMM 0 ~19.2K
socket, and bAud is set to 0~220, the COMM output can
work as retransmission output. It can retransmit channel
2 input or cyclically retransmit all input channels into linear
35
current. bAud defines the output high limit, and Addr
defines the low limit. The unit is 0.1mA. For example, to
output 4~20mA current, Addr should be set to 40, and
bAud=200.
Loc=0: Allow to display and modify the field parameters
only, which is defined in EP1~EP12.
Loc Parameter lock 0 ~9999
Loc=1: Display the field parameters, without modification.
Loc=808: Allow to display and set all parameters.

When configuration of the instrument is completed, most
parameters are able to hide from field operators to avoid
improper configuration.
