Ⅳ、Running and Operation
CJLC-9007 has 8 keys，as show in figure 4.1-1. The function of them is different on the different display screen. Reference details are in table 4.1-1.
4.2 Running menu
When the power is on，the meter will enter into the running menu, it includes the menu of system detect，system password, temperature and humidity parameter setting, print setting, system time setting.
4.2.1 System detect menu
Communication detect menu, as show in figure 4.2.1－1
When the power on, it shows system detecting menu, after 3s , the meter automatically enters into running menu.
4.2.2 Running menu
Running menu as show in figure 4.2.2－1
4.2.3 System password menu
System password menu as shown in figure 4.2.3－1
If it needs to enter system, check or modify system parameter，press function key（SET）for 3s，it turns up system password menu，input correct password（when the system password is 18,it can modify all the system parameter, the other value just can look over）.
4.2.4Temperature and humidity parameter setting menu
P1(P2): Scale factor in PID control loop，can adjust between 0.0%～200.0%, the bigger the scale factor，the stronger the regulating effect，and the system action will get sensitive，and its speed will accelerate，whereas，the regulating effect will get weak. If the scale factor is big, it will make the system unsteady.
I1(I2)：Integration time in PID control loop，can adjust between 0~3000，the smaller the integration time, the stronger the integration effect, it will make the system unsteady，but it can eliminate steady-state error，and improve system’s control accuracy，whereas，the integration effect will get weak.
D1(D2)：Differential time in PID control loop，can adjust between 0～200，it can reform system dynamic characteristis，the bigger the differential time，the stronger the differential effect，Overshoot is big，adjusting time is short；when the differential time get smaller, the overshoot will get bigger ,and the adjustment time will be longer, so the differential time selection should be suitable.
A1(A2)：Deviation alarm，when the measuring value is bigger than fixed value +A1(A2),it will occurs alarm. when the measuring value is smaller than fixed value -A1(A2)，the alarm will unchain alarm.
SC1(SC2)：Dry and damp thermosis error correction，be used as sensor shift correction，to compensate the error of sensor signal itself（When revise damp thermosis, it should not add water，first press 3s，make humidity display position turning into flickeringly show damp thermosis state，check the error value，and then exit, enter into SC2 to correct）.
N1(N2)：Control duty cycle，when the system heater power is bigger than the needed power，it will make the system unsteady，properly minish heating duty cycle.
4.2.5 Print setting menu
Data and curve: Print interval time，when T = 0, No printing function but have communication function
4.2.6 Communication setting menu
Address: The meter’s number in the control system
Baud: Communication baud rate
4.2.7 System time setting menu
System time setting menu as show in figure 4.2.6－1
Print setting menu as shown in Figure 4.2.5－1
Ⅴ、Fault analysis and removal
It is strict to select the components for CJLC-9007. Advanced technology and management is applied to the production of CJLC-9007. The exception rate is very low because the equipment is strictly examined in factory. If you operate according to the manual, no problem will occur. Some trouble is always caused by improper operation. If you find the trouble that can’t be eliminated, please record the phenomenon of the trouble and inform the local agent or our home company in time. Several common troubles are listed in Table 5-1.
Table 5-1 Common Fault removal
|Abnormal electrify||1、poor power wire connection 2、power switch is not closed||Check the power|
|Signal display do not correlate with the facts. “HH”||1、wrong signal connection2、sensor isn’t be connected||1、check signal wire2、check sensor connection|
|Abnormal output control||1、wrong alarm limit setting||1、reset limit value|
