4 1. Operating Panel 1. The operating panel is divided into the following functional sections: F1 F F3 F Hold Prog C 0 E Start Stop 1 Display 5 Operating keys 2 Keyboard 6 Program label 3 Cursor keys 7 Main switch 4 Funktional keys 1.1. Display 1.1 The display supports the exchange of information between the operator and the machine. Two different basic pictures are displayed which are divided into 6 windows. These window numbers are indicated in the texts picture 1: shows the computer in the main menue picture 2: shows the computer in the programming mode

5 1. Operating Panel 1. 2 If a program has been selected resp. if a drycleaning program is in progress, the display indicates the current process function and its parameters. Programming, program changes and the copying of programs are possible for the operator after input of a self-determinated 4-digit code number. The code number is set to 8888 by BÖWE company. On request of the operator this number can be changed. The change is carried out by a BÖWE technician. When actuating a key it has to be generally observed that the monitor change appears slightly delayed! 1.2. Functional keys 1.2 The functional keys mainly serve to enter the programming, temperature and functional number interrogation and to obtain program information during the cycle. Functions of the keys: F1 F2 F3 F4 Interrogate cycle information, e.g. motor speed, temperatures Programming Interrogate and change operating functions Temperatures of connected sensors are displayed 1.3. Keybord 1.3 The keyboard has the following keys: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 for entering numerical values. Cursor keys: Arrow to the left (cursor left) Arrow to the right (cursor right) Arrow down (cursor down) Arrow up (cursor up) Operating keys: "C" mainly to delete undesired entries "E" mainly to accept (confirm) entered values in the computer "HOLD" to show the program before starting it, to reject a program "PROG" informs the computer that the next entry is a program number or to reject a program: prog + hold "START" to start programs STOP to stop programs All actions, which are actuated with the operating keys, can be read in the LCD operator guidance.

7 1. Operating Panel Depending on the machine type various symbols are not in operation!

8 1. Operating Panel Main switch 1.5 Rotary switch to switch machine on or off. 5 In OFF position (0) no functions are possible. In ON position (I) the machine is ready for operation and the control panel is locked Definition of terms 1.6 PROCESS FUNCTION is a main function (operating condition) which is necessary in a drycleaning cycle with at least one program step. PROGRAM STEP Carries out a process function. It normally comprises several optional parameters. STEP NUMBER is the numbering in sequence of operation in the entire program. OPTIONAL PARAMETERS are the possible conditions of the program steps with one step corresponding to a certain combination of optional parameters, e.g. pumping tank to tank with the optional parameters from still I, to tank II and 2 minutes. PROGRAM is a useful sequence of process functions to carry out a special task.

9 6 2. Control Start-up 2.1 Switch on main switch! The following messages are shown consecutively on the display: Manufacturer of the Computer hardware: Berthel GmbH Manufacturer of the machine: BÖWE Textile Cleaning Software version e.g.: V0.7 Machine model e.g.: PX16 Only with hydrocarbon machines, at this time the flash point of the solvent used is displayed (e.g. flash point > 55 C, hydrocarbon solvent) Now press the C key. Number of deodorising program: e.g. P34 Picture 1 Press start key to start program P43. Now the display shows the number of the current program and the time in minutes and seconds until the program ends. Picture 2 A signal sounds at the end of the program. Press stop key. The signal stops and the loading door can be opened after the drum has stopped and the pressure is released. Now press the C key. The display shows P. Now enter the desired program number or press the C key again to reach the main menue. Picture 4 Now you may change to different operating modes. Note: If there are longer stops between the operating cycles, a small amount of solvent builds up in the cage housing. With the deodorising program this solvent is removed from the cage housing. The deodorising program is always displayed, when the main switch was switched off. In this case it has to be started, as the loading door can only be opened after its completion. Anti-creasing protection: If the stop key is not pressed when the signal sounds at the end of the cycle, the last program step (deodorising) is continuing. The refrigeration unit keeps on running, the drum is in gentle reversing mode. After a few minutes the machine is stopped, the loading door remains locked and program P43 is loaded. The opening of the door is now only possible after completion of the deodorising program. The following pictures show the above described procedure as it is indicated in the display of the machine (picture 1-3).

11 2. Control Program selection and start The computer is in the main menue (two dashes on the display). Press the prog key. The display shows P as request to enter the number of the desired drycleaning program. Enter desired program number. The entry appears on the display. Press start key. The selected cleaning program runs automatically. After starting the program number and the remaining cycle time are displayed. The cycle time is counted down in seconds. Example: Program 1 (1-bath) Display in main menue Entry Explanation prog Activate program selection P 1 Desired program = 1 P1 start Start Machine P1 31:55 Selected program and cycle time After a drycleaning program has been started, the current processing step (e.g. pumping) is displayed with its optional parameters. It is also possible to load the program before starting. To do so press the hold key after having entered the desired program number. Then it is possible to select a definite step of the program as starting step with the cursor keys and. Now you can start the program with start or reject the program as described in Note: Selection of the drycleaning programs see operating manual of the corresponding machine model. If the display shows E755 after pressing the start key, the locking of the refrigeration unit is active. This function protects the unit. The program starts when the "C"-key is pressed and a certain preset period of time has elapsed. If a wrong program number has been entered, it can be corrected before the start. Press the C key to delete the entry and enter the desired program number.

12 2. Control 2. 9 Example: Change from program 2 to program 4 Display in main menue Entry Explanation prog2 Program 2 has been selected P2 C Delete entry by pressing C P 4 Enter the desired number P4 P4 has been selected and can be started by pressing start If a program has already been started, it can be changed, see section Remaining program step time During a current program the minutes and seconds of the remaining program time (window 1) and the remaining program step time (window 3) are permanently displayed Program end and restart An acoustic signal (horn) sounds at the end of the drycleaning program, the remaining program time has run down to zero. Press the stop key, the signal stops and the loading door can be opened. If the machine is still under pressure, a note is displayed. Delete this note by entering C and wait until the loading door is unlocked. The number of the last program is still shown on the display. If the same program shall be run again, simply press start after loading the cage and closing the loading door. (Attention: changes, e.g. drying time extensions with 6E, have to be entered again). For any other program or operating mode press the C key. The computer returns to home position by pressing the C key twice and new entries can be made Interventions in the currently running resp. loaded program Interrupting the program Pressing stop interrupts the drycleaning process and stops the machine. The drycleaning process is continued by pressing start Skip parts of a progam If a program has been interrupted (see 2.3.1), it is possible to skip or repeat program steps by means of the keys and, even to the program end (= rejection) or start. Every time you press these keys one program step is skipped. The drying and reduction step cannot be skipped on KWL-machines. The display is continuously updated. The programming field shows the process function, which would be active, if the program was to continue. The display shows the remaining cycle time. Thus it is always possible to determine the actual program position of the control..

13 2. Control Rejecting a program 10 When a program is interrupted (see 2.3.1) press the prog key. Now end the program by pressing the hold key. The program is rejected. Window 6 shows how to proceed further. If another key is pressed, the program remains interrupted without any change. Important: If a program is rejected, make sure that the cage is free of solvent. There are two ways to do this: a) When skipping program steps, stop at the step to which the process function pumping out of solvent is allocated. Continue drycleaning process with start until the solvent has been pumped out. Continue program with extraction, drying and deodorising until the signal sounds. Continue as described in b) In manual operation enter and start process functions pumping out of cage and drying with deodorising. Note: After a drycleaning program has been started the computer control locks the loading door. It will remain locked until the garments have been dried and deodorised, the cage has stopped and the machine is pressureless Changing the program step times of a current function Activate the black input field by use of any number (e.g. 1) while the program is running and thereupon enter "50E". In window 3 the remaining time of the program cycle is displayed by minutes and seconds. This time can now be modified. The black field shows the time that can be overwritten. Enter the desired time in minutes and press the key "E". Thereafter enter the desired time in seconds and press the button "E". The modification is now completed. The display (window 1) shows the changed remaining cycle time. The program step time can be changed several times within one program step. In case the minutes were entered incorrectly, you can get back with the button After the cycle is finished these changes are erased.

14 11 2. Control Final drying time extension By pressing F1 and following 6E, by entering numbers in minutes and by confirming with E the drying time can be extended by max. 7 minutes. Changes in the last program get lost when restarting the program and have to be done again. An entered extension time for the drying step is added after having unlock the dryingcontroller. The entered drying time extension can be deleted by entering F1 and <6E> and overwriting with This takes place, if E is pressed after overwriting Modification of Extraction speed During an extraction step the current extraction speed is displayed. Speed can be reduced in increments of 50 rpm with the -key in case the machine shakes considerably e.g. due to an imbalance. In the next cycle the initial speed is set again.

15 12 3. Programming General information 3.1 A drycleaning program comprises individual program steps. Each step has a certain process function which has to be determined by optional parameters. Note: To copy an existing program and to change it afterwards is possibly quicker than the input of a new program and reduces the fault possibility (see 3.6). Program input (example see next page) Information regarding programing: Process functions have to be entered in correct sequence. When arranging the process functions it has to be observed that this is done properly, e.g. at the end of a bath first pumping out of solvent, then extraction, drying, etc. By pressing the function key F2 you reach the programming mode (picture 1 on the display). The display (window 3) shows the black input field, enter code number with the numerical keys (e.g. 8888E ). The computer changes to the process function display (picture 2, next page). Window = process functions Window 3 = n1 step number P symbol for programming 1 function number (e.g. for pumping up) Window 4 = text for process function (definition of the selected symbol) Window = operator prompting text Approach desired process function with the cursor keys or confirm the proposed process function (e.g. pumping up) with E (field has a black background). After entering a process function the display (window 3) shows PAR (abbreviation for parameter) and a number. Then enter an optional parameter. From tank I is a parameter proposed by the computer, if desired, only press E. Otherwise approach desired parameter with the cursor key and accept with E (only one parameter, as displayed in window 2, can be selected = operator guidance). For some optional parameters it is possible to enter 00, if none of the selectable optional parameters are desired (e.g. no addition). If a parameter has been entered, the corresponding symbol is displayed in window 1. The parameter proposals are continued by the computer until the process function has clearly been determined. If the parameter requires a time entry, the display (window 3) shows a 4-digit indication. The time has to be entered in minutes (max. 99) and seconds (max. 99). The position where entries have to be made is marked in black. When the minutes are entered confirm with "E", thereupon enter the seconds and also confirm with "E". Continue entering parameters until the display (window 3) shows the next step number. Enter next process function and continue as described above until the last process function has been entered, then store program.

Prog 23E Enter desired free program number e.g. 23, program input is stored The last step of a drycleaning program always has to be deodorising resp. adsorbing so that the signal will sound after program has been finished.

19 3. Programming Level and additional pumping up (B) 3.2 If the solvent level remains below the needed level, there will be an additional pumping up during the whole step time. Without the parameter the step is finished when the level is reached first independent of the remaining time Change entries 3.3 By pressing the C key one time the entry on the display is erased (number resp. time). The desired entry can be made. By pressing C several times you can return to previous parameter entries within one program step. The displayed parameter can then be overwritten and accepted with E Store program 3.4 Last process function has been entered, the display (window 3) shows the next step number and P. Press the prog key. Enter number under which the program shall be stored (only entering the number of a free program position is possible). Press entry key E. The program is stored. Then the computer shows the basic position Copying of a program General information Common drycleaning and maintenance programs, which are sufficient for most of the processes, have already been stored by BÖWE. These programs cannot be changed on the program positions. However, it is possible to copy them onto a free program position and then change them (see 3.7) Copying Computer in home position. Press the prog key and then enter the program position number of the program which shall be copied. Press the prog key again, enter code and press the E -key. And then enter the program position number onto which the program shall be copied. Finish entry with E. When the program position number is displayed, copying is finished. Note: Not only fixed programs can be copied but also each program position.
