Motors
| Motors |
The motors are controlled by the switches in the switch unit and are monitored by the PSM. When the motors are running, the control module detects the pulses from the Hall sensors, which are used for programming. To change the direction of rotation of the motors, the motor poles are reversed.
The following motors can be controlled from the switch unit:
| • |
electric motor (357Da) moves the seat forwards or backwards
|
|
| • |
electric motor (357Db) raises or lowers the seat front
|
|
| • |
electric motor (357Dc) raises or lowers the seat rear
|
|
| • |
electric motor (357Dd) changes the backrest inclination.
|
