CAUTION: do not adjust this trimmer unless strictly necessary. In any case, always
check the cause of the increased current in play (increased friction, mechanical parts
interfering with movement, electrical problems on the motor) before adjusting the
trimmer.
CAUTION: every time the trimmer is adjusted to raise the level of current absorbed by
the motor, make sure it is not greater than 5A, the maximum value allowed by the
motor.
When the motor reaches the front or back limit, its inability to continue causes an increase in the
current absorbed by the motor, and thus the Bio servo board generates an alarm signal to the CPU
board.
During the reset procedure when the machine is switched on, this alarm signal is used to determine
the limits of the motor: the motor moves forward (up) and then back (down) a few cm, until the
board sends an alarm signal. This position corresponds to the home reference (zero) of the seat
motor position, and all other positions will be gauged based on it.
