Differential time:The system oscillation can be
prevented by reducing the differential action to a
suitable value. The larger the value is, the stronger
the differential action is. Unit: s
Integral time, the smaller the value is, the stronger the integral action is,
otherwise, it is weeker. and the more it tends to eliminate the deviation
from the set value. The deviation may not be eliminated if the integral
effect is too weak. Unit: s
Proportional band: the smaller the setting value is, the faster the system
responds; otherwise, it is slower.Increasing the proportional band can
reduce the oscillation, but it will increase the control deviation. Decrease
the proportional band can reduce the control deviation, but it will cause

Setting parameter reserve position: 0 (EEP):EEPROM
with power failure protection; 1(RAM): RAM without power
failure protection. Description of setting parameter storage
location: EEP and RAM. EEP means that the setting
parameters are written into EEPROM and can be
permanently saved after power failure.It is generally used
for factory setting parameters of equipment. Because
EEPROM has the limit of writing times, too many and too
frequent writes will be damaged;RAM: it means that the
parameters are stored in RAM without writing limit and will
not be damaged due to frequent writing. The parameters
set after the equipment is powered off will not be saved.
After power on, they will be restored to the parameters
saved in EEPROM by the equipment manufacturer.It is
usually used for frequent parameters writing when
communicating with the upper computer PLC.
The method of using this parameter is to set this parameter
to EEP first. After the equipment factory has finished debugging
the equipment and set the parameters, the parameters
are saved in EEPROM, and then PRS is modified to RAM,
and the equipment is delivered to the user for use, so as to
prevent erroneous modification or long-term communication
writing data from damaging the EEPROM.
RUN/STOP reserve position: 0 (EEP):EEPROM with power
failure protection;1(RAM): RAM without power failure protection.
this parameter method: if the instrument is required to be in stop
mode every time when it is powered on, first set RSS to EEP,
and then set "start stop operation" = STOP. This setting parameter
will be saved for a long time; Then set RSS to RAM. When using,
the upper computer starts/stops the instrument, which is stored in
RAM. After power on again, the instrument still enters STOP mode.

2）Before auto-tune procedure, 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 larger than SV.
3）Before auto-tune procedure, please set a proper alarm value or eliminate the alarm condition, in
order to prevent the auto-tune 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 limiting, 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, immediately long press “ ” key to enter auto-tune
mode, then the AT indicator light is on.。
7）The auto-tune 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 goes out, it automatically exits auto-tune mode, PID parameters will be updated
automatically, and then the meter will control automatically and exactly.
9) During the auto-tune procedure, below actions will cause the termination of the precess, long press
“ ” 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-tune is carried out,
the best PID parameters still cannot be obtained.
11）Experienced users can set a proper PID parameter according to their experience.

Note ①: The register number is formed by converting the address into decimal and adding 1, and
then adding the register identification code 4 in front; for example: the register number of the data
address 0x2000 is 8192+1=8193 and then adding 4 in front, that is, the register number 48193;
Related applications can be seen such as Siemens S7-200 PLC.
Note ②: Channel status indication, when the data bit is 1, it means executing, and when it is 0,
it means not executing.

It uses Modbus RTU communication protocol, read 04 area to keep the register function number
be 0x03, write function number 0x10 or 0x06, adopts 16-bit CRC check, it does not return the
check error. The data type is a 16-bit signed or unsigned integer.
Data frame format:
1. Read register
Example: The host reads PV1 value (PV1=200)
The register address of PV1 is 0x2000 ("0x" stands for hexadecimal), because the data type
of SV is a 16-bit integer (2 bytes), 1 register. The decimal integer 200 is converted to hexadecimal
as 0x00C8. Note: When reading data, you should first determine the decimal point position and
convert the read data to get the actual value.

2. Write multiple registers
Example: The host writes multiple registers (using function code 10) write SV1 value (SV1=150)
The register address of SV1 is 0x2110, because the data type of SV1 is 16-bit integer (2 bytes), 1
register. The decimal integer 150 is converted to hexadecimal as 0x0096. Before writing data, convert
the data to the corresponding magnification and then write the data to the meter.

Communication abnormal handling:
In the case of abnormal response, the highest bit of the function number is set to 1.
For example, if the function number requested by the master is 0x03, the corresponding item of the
function number returned by the slave is 0x83.
0x01---Illegal function: The instrument with the function number sent by the host does not support it.
0x02---The address is illegal: the register address specified by the host exceeds the allowable
range of the instrument parameter address.
0x03---Illegal value: The write data value sent by the host exceeds the allowable range of the
instrument.

whether the work temperature is normal & the input signal selection is correct.
XI. Simple troubleshooting method
3. Single channel power limit:
1) OLL and OLH are used to limit the mini to maximum range of the single channel output control
amount, which is 0 to 100% by default.
2) The OLL setting value must be less than the OLH setting value.
3) If the OLH setting value is too small, the control efficiency and speed will be affected, and the target
value may not be reached.
4) The single-channel power limit cannot realize the total power limit function.
4. Total power limit function:
1) When the actual power LPH setting value of each channel is greater than 0, that is, this channel
participates in the function of total power limit SLPL and power even distribution.
2) If the total power limit value SLPL is set too small, it will affect the control response speed of each
limit channel, or even fail to reach the target value. Therefore, it should be set appropriately according
to the actual situation.
3) After setting the LPH and SLPL values, the controller will automatically stagger and distribute the
load power evenly to avoid the impact of the simultaneous full power output of each channel on the
grid.
4) The channel that is performing auto-tuning will temporarily exit the total power limit, and will
automatically recover after the auto-tuning is completed.
