Initialization; List Of Error Codes - Brother LZ2-B855E Service Manual

8. ELECTRIC COMPONENTS

8-9. Initialization

If the data such as parameter data has been changed by mistake, it is possible to reset the data to the factory setting.
(1) Initializing the panel setting value --- Initializing the setting values from the panel such as pattern number and zigzag
(2) Initializing the parameters -------------- Initializing the parameters and the memory switches.
(3) Initializing the speed --------------------- Initializing the speed parameters.
(4) Initializing all -------------------------------- Initializing all from (1) to (3) above.
EZ 855
Initializing
1. Turn off the power.
2. While pressing the TEST key, turn on the power. in| will appear on the display.
(If you would like to stop initializing, turn off the power now.)
3. Press the SET key. AL| will appear on the display.
4. Press the key several times to display the type of initializations that you would like.
(AL| indicates all initialization, 5n| initializing panel setting value, NP| initializing parameters, 5P| initializ-
ing speed parameters. To exit this mode without doing any type of the initializations, select En|.)
5. After the type of initialization has been appeared on the display, press the SET key.
After initializing, the machine will return to the normal condition.

8-10. List of error codes

Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall
outlet before opening the face plate of the control box. Touching areas where high voltages are present can
result in severe injury.
