Introduction open during start up. If the lint door/drawer is accidentally opened while a program is running, the program will stop and the display will indicate a diagnostic message. The program restarts once the door is closed and start is pressed. 3. Depression Alarm The program will not start when the pressure alarm is active. The EDG uses the cabinet sail switch to determine if the exhaust blower is operational.
Introduction 5. Motor backward Commands reverse direction of the cylinder motor (reversing models only). 6. Blower Turns on the exhaust blower. In non-reversing models, this controls both the blower and the cylinder motors. 7. Heating On when the cylinder temperature is below the programmed set point. 8. RFU Not used in the USA. Keyboard The keyboard is equipped with the following keys 0-9 : these keys have a different function depending on the situation. 1.
Operation duration of the drying cycle. 5. Press ENTER : if the number is within the allowed range the message “HEAT” appears (requesting the drying temperature). 6. Press ENTER : the number “00000” appears (default temperature expressed in °F or °C, depending on machine configuration). 7. Use the numerical and DOWN keys, as in points 3 and 4, to set the desired temperature. 8. Press ENTER to confirm the input values. The message “PRESS START” is displayed. 9. Press START to start the drying cycle.
Programming Programming Programming includes machine configuration (1 or 2 motors, coin box or no coin box), operating ranges (the desired settings - language, times), and lastly the definition of the behavior of each single drying cycle. All programming phases start by entering the correct password, after which the operator proceeds to enter the desired parameters. All programming phases can be stopped at any time by pressing STOP.
Programming Setting the operating ranges The password required to access this phase is “916”. Proceed as follows : press both keys UP and 1 at the same time. The message “PASSWO” is now displayed, then press ENTER. The display now shows “00000”. Press the DOWN key three times to erase three zeroes starting from the right and then type in the password “916”. Press ENTER. Actual programming starts now. DISPLAY ALLOWED VALUES DESCRIPTION CELSIUS SN Yes/No Yes - Programs and displays in Celsius.
Programming Customizing the individual programs The password required to access this phase is “955”. Proceed as follows : press keys UP and 1 at the same time. At this point the message “PASSWO” appears on the display, then press ENTER. The display now shows “00000”. Press three times the DOWN key to erase three zeroes starting from the right, then type in the password “955”. Press ENTER. Actual programming starts now. DISPLAY VALUES ALLOWED DESCRIPTION Program selections through the UP and DOWN keys.
Details List of phases carried out during program execution During the cooling down phase the display shows the message “COOL DOWN”. This phase differs from the drying phase mainly because heat adjustment now ends. Cool down is completed once the relevant temperature set in low level programming is reached, or when the relevant time expires (also set in low level programming), depending on which of the two conditions occurs first.
Details Restart after a power failure In case a power failure occurs while a program is running, the following information will be stored in memory : number of the program under way, the residual time, the phase under way and any other data required to restore the operating conditions in force right before the power failure. When the power supply is restored, the display indicates the program interrupted, and the user can press ENTER to start it or STOP to stop it for good.
