8. PROCESSING IN THE ATL 500/800
Switch on the ATL. The processor will automatically perform a self-check. When this is complete, the LCD display will show the previously used process number and type. All displayed digits will blink on and off. Then, using the "Up arrow" or "Down arrow" buttons, select the required process number and type.
8.2 Auto-Start and Standby Modes
The ATL 500/800 now offers you two alternative modes of operation:
- Auto-Start -- Start the process with the tank coupled to the processor. In this case, the typical warm-up time from room temperature to 38°C will be approximately 15-20 minutes.
- Standby Mode -- Temper the water jacket first. Coupling the tank and adding solutions later. In this case, tempering time will be reduced to approximately 10-15 minutes.
Auto-Start: Mount the loaded tank to the processor by coupling it to the lift arm. Fill the chemical bottles with the correct amount of solution using a graduated cylinder as follows:
Small Tank
- 1x 135 150 ml
Big Tank
- 1x 120 150 ml
- 1-2 sheets of 4x5" film 150 ml
- 2x 120 300 ml
- 2x 135 300 ml
- 3-6 sheets of 4x5" film 300 ml
On the ATL-800 you can also select the easy-fill technique, when using the chemicals in the upper supply bottles. Just open the taps and let the solution fill into the bottles until one half of the level indicator turns black for 150 ml or until the whole indicator turns black for 300 ml. Then close the taps.
Press the 'START' button
Select 'big' or 'small' tank using the "Up Arrow" or "Down Arrow" buttons Press the 'START' button again. The processor will start heating the water, chemicals and tank, and 'START' will blink. As soon as the correct process temperature is reached in the first chemical bottle, the process will start automatically and finish with the final wash.
After pressing ¿ (Enter) the tank will stop rotating, the lift arm will rise, and the tank can be removed from the processor. The processor will then remain in its waiting position, with the heater switched off and the LCD display flashing. If no further processing is planned, the ATL-500/800 can be switched off using the main power switch. The film can then be removed from the reel, and stabilized in a separate container for one minute. The film should then be wiped using a clean squeegee (such as the JOBO #3350 Film Wiper) and hung up to dry, preferably in a closed film dryer (such as the JOBO #3523 Mistral II.)
Standby Mode: This is a suggested mode of operation to allow the ATL-500/800 to be prepared for processing before a tank is loaded. The application here would be a photographer who wanted the unit to be ready for immediate processing after photography.
- Fill the chemistry bottles with an appropriate amount of solution. (Make sure to close the bottle caps firmly.) Switch on the ATL-500/800.
- The processor will automatically perform a self-check. When this is complete, the LCD window will show the previously used process number and type. All displayed digits will blink on and off.
- Using the "Up arrow" or "Down Arrow" buttons, select the required process, and confirm using the ¿ (Enter) button.
- Select either the big or small tank by using the arrow buttons.
- If the temperature is less than 22.1°C, the temperature will flash.
- Press ¿ (Enter) to activate the Standby Mode. The wash water and chemistry will now temper, and the ATL-500/800 will enter the standby mode, awaiting tank connection.
- Connect the tank to the processor lift arm.
- Press the START button. The tank will rotate during a 5 to 7 minute pre-warm cycle, and then the process will start automatically.
Note: The chemicals and tank should not be pre-warmed outside the processor. Mounting the tank, filling in chemicals and pressing 'START' should be done in a quick sequence. When operating in standby mode, the water jacket is tempered continuously. To avoid excess energy consumption, this mode should not be used continuously.
Filling the chemical storage bottles:
Make sure the bottle caps are closed firmly, as air pressure is used to transport the chemicals to the tank.
8.3 20°C and 24°C B/W Film Processing (ATC)
The ATL-500/800 continuously measures the temperature of both the wash water and the chemistry for the 20°C and 24°C processes. If either of these is higher than the selected process temperature, the ATL-500/800 will automatically increase the process temperature to the higher measured temperature. It will start the process once the chemistry in bottle 1 and the wash water are all at the correct temperature. The developer time will then be modified according to the time and temperature curves shown below. This function is ATC, automated temperature conversion.
The maximum allowable temperature difference is +4° C from the selected process temperature. If the difference is higher, the process will stop, displaying: "out of range". Select a 24° C process instead of a 20°-process, if 20°C-process is out of range.
