Parameter-No.: 00639
Reset errors, Teaching of position 1
Gen. 1 + 2
Access:
RW
1. Reset errors:
A SELECT-Telegram to Parameter 00639 with "0815" = " 30 38 31 35 " reset error messages.
Requirements: Rotor is in standstill, Key-Lock is in LOCK2 (right position).
The following error messages have to be reset by a mains reset:
ERROR 1 , 2 , 96 ( tacho errors ) , 12 (versions error ) , 62 (wrong motor code )
2. Teaching of Position 1 and store it in the control unit via serial protocol:
Requirements: Rotor is in standstill, Key-Lock is in LOCK2 (right) position.
Theory:
The rotor position 1 (bucket no. 1 is under the hatch) is determined by the incremental encoder tracks A and
B. This rotor position must be set by hand and then stored in the control panel.
The angular distance from position N (zero pulse) to rotor position 1 is determined by
the encoding pulses of the incremental encoder.
Beginning at position N (zero pulse) the pulses are counted up to rotor position 1 when turning the rotor
counter-clockwise.
When the START-Key is pressed, the control panel stores the calculated pulses.
Sequence:
Send a SELECT telegram to Parameter 00639 with value "0100" to start the adjusting (teaching).

Setting:
- Turn the rotor slowly counter-clockwise by hand
until the centrifuge beeps.
--> Therewith the position N (zero pulse) is detected.
After reaching the position N (zero pulse) the actual position is shown in the display

Continue to turn the rotor slowly in the Hettich direction (counter-clockwise) until the desired position 1 has been
reached and hold this position.
Send a SELECT telegram to Parameter 00639 with value "0101" to save Position 1 in the EEPOM.
