3.1.3 Single-screen and single light column dispaly (take 80 x 160 for example)

3.1.4 Explanation of each parts for instrument, see table 2:

3.2 Engineering parameter setup (first-level parameter)
Under the display state of PV measured value display, presses SET key, the instrument will enter engineering parameter setup state. Only when CLK =00 or 132, engineering parameter can be modified. Press SET key to confirm after first-level and secondary parameter is modified. Please notice that the instrument parameter have someplace not give show because of instrument’s different functions. Engineering parameter setup see table 3:

Note 1 Lower limit control or alarm: output when the PV is below the setting value, stop output when the PV is above the setting value + return difference value. Upper limit control or alarm: output when the PV is above the setting value, stop output when PV value is below the setting value—return difference value.
Note 2: As the different alarm number, the settings which alternately display each setting value may have corresponding modification.
3.3 Users parameter setup (secondary parameter)
Warning! Non-engineering design personnel are not allowed to modify the following parameters, or it will make the instrument control mistake!
Under the display state of PV measured value display, presses SET key to set CLK=132, first press SET does not release and press increase key again, after 5 seconds, can enter into users parameter setup. Users parameter setup are as table 4:

3.4 Operating method
3.4.1 Switching of input signal: modify users parameter SLO, see table 1 for details.
3.4.2 Set of PV/SV decimal point: modify user parameters SL1, see table 4, PV/SV decimal point of thermocouple, thermo resistance cannot be set, decimal point of the Pt100.0 and Cu50 is fixed to be one place, others have not decimal point. Standard signal can be set.
3.4.3 Set of lower limit control or alarm value: set ALX value to be start point of lower limit value, ALX+AHX is stop point of lower limit value (X means
1, 2, 3, 4, below is alike), see table
3. 3.4. 4 Set of upper limit control or alarm value: set ALX value to be stop point of upper limit value, ALX-AHX is start point of upper limit value, see table 3. 3.4.5 Set of upper/lower limit control mode: modify user parameters SL2 —SL5, the detail see table
4. 3.6 Set of internal/external cold-compensation and light column display: modify user parameter SL6, see table 4, if users choose external cold compensation it should be connected Cu 50 sensor
3.4.7 Control/alarm state set when a sensor was disconnected: modify user parameter SL8, see table 4. Control or alarm output according to primary setting mode when the ten’ s place of SL8 setting value is 0, that is when the instrument shows OH, upper limit has output, when it shows OL, lower limit has output; The instrument will keep disconnection state when it displays 1, that is when the instrument display Err it will remain initial control or alarm; the instrument will remove control or alarm output when it is 2, that is, when instrument displays Err it has not control or alarm output.
3.4.8 Set of device number and baud rate: Instrument’s device number should be unique in the RS485 communication. Band rate of upper-level machine and the lower-level machine should be accord, see table 4 for user parameter DE and BT.
3.4.9 Set of transmission output range: modify user parameter OUL and OUH, see table 4, its span should be less than or equal to display range. When the sensor was disconnected, displays OH means transmitting output maximum or displays OL means output minimum.
3.4.10 Set Upper and lower limit of light column display: See table 4 for user parameter PVL and PVH.
3.4.11 Set measured small-signal removal: in the field of measuring flow, when flow is smaller, measured value undulation is bigger, and error is bigger. the usual method is small signal removal. User parameter (table 4) SLU meanings shows % of range, that is, when (measured value =range) X % ≤ .SLU setting value, the instrument shows 0. Instrument has small signal removal function only when it with evolution function.
3.4.12 Methods to return to measure state:
•Manual return: Under parameter setting mode, pressing SET key for 5 seconds the instrument will automatically return to measured value display state.
•Automatic return: Under parameter setting mode, does not press any key for 30 seconds, the instrument will automatically return to measured value display state.
•Reset return: Under parameter setting state, pressing RESET key, the instru-ment will enter measured value display after self-check again.
3.4.13 Display content of thermo-resistance, thermocouple disconnection instru-ment: when the ten’ s place of SL8 parameter is 0, instrument display OL or OH; when the ten’ s place of SL8 is not 0, instrument display Err.

Modification of transmission output signal

Short-circuit ring which is designed on the transmission output board may chang the output of current or voltage according to method of table 6. User parameters may be set by method of table 7, Pb3 and KK3 may change the upper/lower range of output signal.

	DC current output	DC voltage output
Short-circuiting ring state
Signal output end voltage, resistance	voltage: 20—30V resistance: infinite	voltage: 0-,-.10V resistance: 250-5000 or infinite

Signals Pb13, Pb23, Kk13, Kk23 output different ranges may be set according to the following table: Table 7

Calibration of display transmit measure

6.1 Calibration of display range: When error exists between H/L limit display range and actual range, range can be adjusted by modifing Pbl and KK1, the details are as the following method:
ICIC1= scheduled range ÷ display range X initial Kk 1 (scheduled range: SLH-SLL)
Pbl= lower limit of scheduled range—lower limit of display range X KU +initial Pbl

For example: a DC current 4-20mA input instrument, measuring rang is
200-1000Kpa, while calibration, find that when input 4mA, displays
-202, when input 4mA, displays 1008. (Initial Pb171, initial KK1=1)

According to the formula:
KK1=scheduled range ÷ display range X initial KK1
= [1000- (-200)] ÷ [1008+202)] X 1
= 1200+1210 X 1 0.992

Pbl= lower limit of scheduled range-lower limit of display range X KK1+ initial Pbl= -200- (-202 X 0.992) +0=0.384≈0.4
Set: Pb17,1.4, KK1 .992

6.2 Calibration of transmission range: When error exist between H/L limit transmission output and actual range, range can be adjusted by modifying Pb3 and
KK3, the details are as the following method:
KK3= scheduled output range ÷ actual output range X initial KK3 (Scheduled output range: OUH-OUL)
Pb3 = scheduled lower limit output-actual lower limit output X Kk3 + initial Pb3

For example A DC current signal 4″-20mA input instrument, measuring range is -200-1000Kpa, transmission output is 4-20mA; While calibration, find that the instrument display is very accurate; when input 4mA and 20mA, the instrument output 3.9mA and 20.1mA respectively, set initial instrument Pb3=20.0, KK3=1.000.

According to the formula:
KK3=scheduled output range ÷ actual output range X initial Kk3
= (20-4) ÷ (20.1-3.9) X 1.000
= 164-16.2 X 14.988
Pb3= scheduled lower limit output-actual lower limit output X Kk3 + initial Pb3
= 4-3.9 X 0.988 +20.0 =20.1
Set: Pb3=20.1, Kk3=0.988

Note: Before calibrating transmission output, first ensure that the display is correct or not, Pbl, Pb3 modified value precise to one digit behind decimal point.
