Don't change the settings during PID self-setting, because one change leads to one restart, then
PID time is prolonged.
When we use meters with the function of curve procedure control, we should stop the curve
procedures first, set the PID self-setting according to the above steps, then start the curve procedure
control.
If we only choose PID self-setting, please set the differential time to OFF so that it is not
changed when the meter is in the process of PID self-setting. In the system that doesn't allow output
signals change frequently, we should choose PID self-setting.
e. Problems display
When the input sensor breaks or the input signals exceed the max range, the upper screen will
show the fault code snb; when the sensor short-circuits, or the input signals is less than the min
range, the upper screen will show the fault code ur.
In general, the meter works in the state of auto-control. When the meter shows Snb or ur, it
shifts to start working very soon, outputting powers. Then, the power can be controlled by button
▲ and ▼,at the same time, the MAN lamp flickers. Once the problem is solved, the meter will
return to the state of auto-control.
f. Software configuration (code and meaning of function parameters)
Set the configuration password as 808 (the parameter code Loc), when the meter shows PV,
press button PAR and ▲ for 3 seconds to enter the menu of software configuration. The upper
screen shows code of the first parameter, and then we can modify the parameter value in the state of
IdLE. After the modification, press PAR again, then the code and value of the next parameter. In the
meantime, the modified data is saved in the memory.
If no operation within 16 seconds after display of the last parameter, the meter returns to the
state of PV.
After the configuration, we should set the password as some other numbers besides 808, to
protect the data from unconsciously modification of the operator.
