EAT MOTOR TEST
The machine checks whether it is possible to command and control the seat motor by sending a
movement signal and checking the encoder and alarm signals it receives from the Bio servo board
(LP Bio servo). Under normal conditions, the test takes place as follows:
•
the machine moves the seat motor;
•
it waits for it to reach one end;
•
when it arrives, the Bio servo board (LP Bio servo) produces an alarm signal that it sends to the
CPU board;
•
the machine considers this to be the reference value, and moves the seat motor (based on the
configuration parameters) until the default position is selected;
•
the test is complete.
CAUTION: under normal conditions, the Bio servo board (LP Bio servo) should not
produce any alarm signal after the first, considered normal.
Reasons that may cause the test to fail include:
1. Mechanical problem
If, during movement and after receiving the normal alarm signal, the CPU board receives 3 more
out of 3 consecutive movement attempts carried out approximately 10 seconds apart, this means
that there is something preventing movement. In this case, the machine aborts the reset
procedure and displays the following message on the LCD:
S E A T P R O B L E M =
F A I L
To exit this error condition, carry out the checks described in paragraph 6.13. “The LCD
displays the message “Seat problem = fail””.
2. Motor problem
If, during movement, the CPU board receives no encoder or alarm signal for approximately 60
seconds, this means there is no movement due to a probable motor fault, In this case, the
machine aborts the reset procedure and displays the following message on the LCD:
S E A T P R O B L E M =
M O T O R
To exit this error condition, carry out the checks described in paragraph 6.15. “The LCD
displays the message “Seat problem = motor””.
3. Encoder problem
If, during movement, the CPU board receives no encoder signal for approximately 60 seconds,
this means there is movement but no encoder due to a probable fault on the encoder itself. In
this case, the machine aborts the reset procedure and displays the following message on the
LCD:
