KEYBOARD

The programmer is equipped with alphanumerical keyboard which enables the input and the modification data.

Besides the normal digital keys there are different special keys too, escribed below.

Key “CLR”: to clear the screen and correct wrong data entry and to quit any menu.

Key “ENT”: it confirms the working you are carrying out. In case you are entering data, it carries out data storage.

Key “ESC”: it stops any working you are carrying out, and resets the previous mask.

Key Arrow  Top and Arrow Down scroll keys.

MAIN MENU

(Accessible only when the rectifier is not working)

Items that can be programmed freely:

TIME – DATE – LANGUAGE – UNIT NUMBER

Items that can be programmed by means of key switch set on “Programming”

CALIBRATION

MICRON CONNECTION

WORKING TEMPERATURE

INITIAL CALIBRATION

• Switch on “Programming”
• Enter the main menu
• Working temperature

If it is different from 18°C (factory calibration value) you must type in the new data. Press ENT

CALIBRATION

Calibration on a small load (it corresponds to 10%-20% of rated current of rectifier) of known surface.

Type in the m2 data and the number of requested microns.

Carry out the anodizing treatment.

At the end of the work press ENT. Calibration on big load (50% + 70% of max current) of known surface.

Type in the m² data and the number of requested microns.

At the end of the work press ENT.

At this moment the device is automatically calibrated in the full range small up to big loads.

Micron corrections (if necessary)

• “programming working” switch set on “working”
• Enter the required density value
• Enter the number of requested microns
• Enter the start button
• At the end of the treatment check the number of microns actually obtained and compare it with the programmed one

If the difference is more than one micron, operate as follows

• Switch on Programming
• Enter the item “micron correction”
• Enter the number of microns obtained
• Enter the number of microns programmed
• Press ENT
• At this moment the device corrects itself automatically

THE USE

After the initial proper calibration (as above explained) the operator must enter the following parameters only:

• Requested number of microns (1/40 microns)
• Current density value (A/dm²) (0.50 A/dm² / 9A/dm²)

(These values remain automatically memorized for subsequent treatments)

When the present number of microns has been reached, an acoustic visual signal is given and the output current of the rectifier decreases automatically and gradually up to 10% approx. of the working value till the stop button is pressed.

PRINT SWITCH

If it is on pos. “Yes”, at the end of the treatment you have automatically the print out of:

Data – start time – end time – duration – surface (SQM) – microns obtained – microns preset – vol – ampere – temperature

Parameters shown on the display during working: microns surface (sqm) time elapsed, temperature, growing up microns

REMARK

In order to carry out correctly the survey of the surface to be anodized it is absolutely necessary that electrical connections bet­ween rectifiers and tank are made soas to avoid anomalous voltage drops (defective connections, imperfect mobile contacts).
