Measuring range low limit and high limit.
For temperature sensor input, please keep the factory
setting value. For 4 ~ 20mA / 0 ~ 10V input, please
set the corresponding range for the low limit and the
high limit. For example, 0~10V corresponds to -20~50,
set FL to - 20, set FH to 50. Setting range:
-1999~9999, associated with DP decimal point menu.
4~20mA analog output low limit and high limit. For
example, 4~20mA corresponds to 0~100, set brL to 0,
set brH to 100. Note: it can be set as reverse analog
output, for example, 100~0 corresponds to 4~20mA.
Current control output low limit and high limit, only
valid for 4~20mA current control output. It is used to
limit the output current amplitude. For example, in the
control of frequency converter, if the motor cannot be
stopped, please set the output low limit OLL to 10%;
in heating control, if the user don’ t want full-power
output at the beginning of heating, please set the
output high limit OLH to 80%.

XI. Key function operation
1. RUN/Stop mode
1）Under the measure mode, press and hold “R/S” key > 3 sec to enter STOP mode, SV
window will display “STOP”, main control output stops or keep the minimum output.
2）Under STOP mode, press and hold “R/S” key to exit STOP mode. Press “ ” key to
modify SV value.
3）Under STOP mode, alarm output and analog output work normally.
2. PID auto-tune operation:
1）Before auto-tuning, please switch off the load power, or set the meter as STOP mode.
2）Before auto-tuning, PV value should meet below condition: when it is PID heating
control, PV needs to be much smaller than SV; when it is PID cooling control, PV needs
to be much greater than SV.
3）Before auto-tuning, please set a proper alarm value or eliminate the alarm condition, in
order to prevent the auto-tuning procedure from being affected by alarm output.
4）Set PID type and SV value; the factory default setting is fuzzy PID.
5）Set as PID control, if there is OLL & OLH output limitation, please set the output to a
proper range; factory default setting is OLL=0%, OLH=100%.
6）Exit STOP mode, or switch on the load power, and immediately press and hold “AT ”
key to enter auto-tuning mode, then the AT indicator light is on.
7）The auto-tuning procedure will take some time, in order not to affect auto-tune result,
please don`t modify the parameters or power-off.
8）When AT light turns off, it automatically exits auto-tune mode, PID parameters will be
updated automatically, and then the meter will control automatically and precisely.
9）During the auto-tuning procedure, below actions will cause the termination of the
precess, press and hold “AT” key, measure beyond the scope, abnormal display, switch
to STOP mode, power-off, etc.
10）Note: In the occasions with output limiting operation, sometimes, even if the
auto-tuning is carried out, the best PID parameters still cannot be obtained.
11）Experienced users can set a proper PID parameter according to their experience.
3.PID heating and proportional cooling control operation
1）Set the control mode OT as 3.
2）PID heating control operates on OUT1; proportional cooling control operates on OUT2.
3）Proportional cooling control OUT2 outputs via AL1 alarm function terminals.
4）Please set the cooling start hystersis DB to a value greater than 5, to ensure the cooling
output will not affect the PID heating control.
5）Please set the cooling control cycle CP1 and the cooling proportionality coefficient PC
to the proper value.
6）When PV value > SV+DB value, the cooling control start to effect; the bigger value of
PV, the longer output time of OUT2
4. Auto-manual switch function
1）Enter common menu, set parameter A-M as “AM”.
2）After return back to measure control interface, press “ ” key to switch auto-manual
operation.
3）When it is switched to manual control, lower line LED will display output percentage:
M0~M100 (corresponding to 0%~100%), press UP key and DOWN key to modify the
output percentage.
4）Before the switch from manual control to auto control, in order to ensure the smooth
switch, please press Shift key to modify the SV value first.
5）After the meter is rebooted, the default setting is manual control and output 0%.

Handling of abnormal communication:
When abnormal response, put 1 on the highest bit of function code. For example: Host request
function code 0x03,and slave response function code should be 0x83.
Error code:
0x01--- Illegal function: the function code sent from host is not supported by meter
0x02--- Illegal address: the register address designated by host beyond the address range of
meter.
0x03--- Illegal data: the written data value sent from host exceeds the corresponding data range
of meter.
Communication cycle：
Communication cycle is the time from host request to slave response data, i.e.: communication
cycle= time of request data sending +slave preparation time + response delay time + response
return time, e.g.: 9600 Baud rate:communication cycle of single measured data ≥250ms.
Meter adopts Modbus RTU communication protocol, RS485 half duplex communication.
Read function code 0x03, write function code 0x10 or 0x06. Adopt 16 digit CRC check, the
meter does not return for error check. Factory default setting: slave address 1, baud rate 9600,
no check, 8 digits data bit, 1 digit stop bit, data type is 16 digits signed (unsigned) int.
Data frame format:
1. Read register
For example:Host reads integer SV(set value 200）
The address code of SV is 0x2000, because SV is integer(2 dyte), seizes 1 data register. The
memory code of decimal integer 200 is 0x00C8. Note: when reading data, should read DP
value or confirm DP menu value first to ensure the decimal point postion, after that transform
the read data to get the actual value. Conversely, it should transform the data to
corresponding ratio before writing the data in meter

Note①: The register number is the address converted to decimal plus 1 and then the register
identification code 4 is added in front; for example: the register number of the data address
0x2000 is 8192 + 1 = 8193 and then 4 is added in front, that is, the register number 48193;
Related applications can be seen, such as Siemens S7-200 PLC.
Note ②: Measurement status indication. When the data bit is 1, it means execution, and when it
is 0, it means no execution.
Note③: DTC communication data transmission sequence description
Reserve
Byte transfer order: when it is 0, the sequence is 1, 2; and when it is 1, the
sequence is 2, 1
