Description of problem Chair keeps

travelling when key is released on the panel.

Does not occur with operation using foot switch.

Chair does not travel to zero position. Chair does not budge.

0 key on panel is not active (gray without frame).

Chair starts travelling uncontrollably

If the chair is moved to a treatment position from the zero position using the HP, the AP remains in the zero position dialog. After removing and depositing an instrument, the AP remains in the zero position dialog. In this situation, the forward foot switch starts the movement to the starting position.

Programmed 4-way foot switch assignment (tilting part / backrest) is lost after switching off (serial no. <3000)

Node AP

If the zero line is in line 1, the queried node (PCB) is in order electrically.

If there are service codes above the zero line, these must be analyzed as follows:

A Evaluate the service code above the zero line (line 3 in this example).

The service code for this node (AP) can be found in the numbers between both vertical lines (01 in this example).

i

NOTE

If the vertical lines do not appear, the minimum configuration is not available (see chapter 2, section 2.3). In this case, refer to the service code list of the corresponding node. In the beginning of this list there is a reference to the column where you will find the service code!

B Take the corrective action for service code 01 (error_high) from the

example, 0C 07).

D Take the measure for service code 0C (error_high) 07 (error_low) from

the service code list.

E Evaluate all additional service codes above the zero line

as described in A–D.
