2. Menu Overview The menu provides all basic operation and setting, It is conventient to choose any function that users need. According to run time, users can know how many Company data time have already spend. 2.1 Monitor A. SV, PV, a program type status. B.
3. MONITOR screen explaining When users have already setup program, the monitor screen provide users to (RUN),(STOP),(ADVANCE), (PAUSE),(HOLD) the programs. The users can see three areas, It includes Low room, High room, Test room. Also can see the present output percent ratio and more the others details. 4.
4.2 Execute reserved start time or not There have two execute methods in reserved start time. RUN: Normal setting, give up reserved start time. Ready: Reserved start time, Month/Day/Hour/Minute. 4.3 Execute reserved stand by time or not When a program have finished running , users can choose TEST END or STANBY . If a user choose TEST END ,when a program have finish running, then a program will test end.
4.4 Execute return ambient tempature or not When a program have finished running , depend on a user demand, back to ambient temp or not. Ambient temp setup range:0~50˚C.Factory default:15~35˚C. 4.5 Execute Power down(Black out resume) or not When a controller is running a program, because unknown factors then a controller power off, after restarting, there are three situations can be selected.
5. DEFROST screen explaining Setup auto defrost function, defrost temperature, defrost time, end defrost. Notice: Auto defrosts or manual defrost is only exist in high temp. 5.1 Auto defrost function Cycle: Calculate auto defrost by cycle. Time : Calculate auto defrost by time. Off : Turn off auto defrost function.
5.3 Defrost time When defrosts the temperature to arrive, defrosts the delay time only then to start to calculate, generally suggested that the time is 5~10 minutes. 5.4 End defrost Users may suppose when the settled experiment ended, whether needs once more to carry out one time to defrost the movement.
6. PROGRAM screen explaining There are four kinds of program to be selected. such as 2Zones,3Zones,Step,Link. Program screen 6.1 Special items for Programs setup 6.1.1 When a program is running, get into stored program can’t change a running program(Red color). 6.1.2 After setup a new program, remember back to MODE SET screen, setup all of function that you need.
6.2 Program type 6.2.1 2 ZONE Pattern(Program) When test condition between heating and cooling, please choose 2ZONE Pattern(Program). Low temp Start Cool Heat start High temp Start Heat Cool start 6.2.2 3 ZONE Pattern(Program) When test condition between heating and ambient temp and cooling, please choose 3ZONE Pattern(Program).
6.3 2 Zone pattern set When test condition between heating and cooling. 2Zone setup 6.3.1 Test name type in Users can type in any test name that they like. Test name make a program easy to remember. 6.3.2 Patterns number Choose Patten number before others setup, because pattern number is different, then setup will be different.
Page 17
6.3.3 Patterns cycle Pattern cycle that mean how many times in running, range limit in 1~9999. 6.3.4 Start test from… Start according to the demand by high temperature or low temperature starts to test. 6.3.5 Wait temp Setup wait temp in high temp or low temp, when temp achieve wait temp, a controller will get into wait mode.
Page 18
6.3.6 Delete a pattern Delete a pattern according to user’s demand. 6.3.7 setup a pattern operate condition Setup pattern operate condition, it include test temperature, spend time, pre wait range, wait mode on/off,time signal on/off. 6.3.8 Running a pattern After setup all the others settings, then push RUN button, the screen will jump to MONITOR screen, start running a program.
6.4 3 Zone and Step Because 3Zone and Step, their setup are the same with 2Zone, so we don’t explain them in here, only show photos in below. Step setup 3Zone setup 6.5 Link pattern Link pattern combine 2 zone, 3zone,step.In Link pattern screen have six block, provide users to input 2 zone,3zone,step programs.

7.TROUBLE HISTORY screen explaining In the screen, you can see trouble message that ever happen in the past. Trouble message include trouble name and date/time. When a controller has an error, it will appear a trouble message, and then users can push RST button back to normal system. That trouble message will save to trouble history.
8.OTHERS screen explaining This screen provide users to adjust system clock, change language, setup back light, adjust LCD contrast, record maintenance, change machine ID, view firmware version. 8.1 Time adjust Adjust a system clock, YY/MM/DD/HH/MM. 8.2 Language change Change language between Chinese and English. 8.3 Back Light on Back light means if users don’t touch panel too long time, the screen will get into dark.
