8000A BT solenoid impact absorbing
The initial value of the memory switch is set so that the lower impact sound of touch back is lowered with
stitching pitch of 2 to 4 mm at the time of shipment.
If the impact sound at touch back is large, change in the braking timing and Duty described below can
reduce the impact sound.
Apply brake immediately before the solenoid for impact sound reduction reaches the stroke end when the
touch back solenoid is activated.
(Apply brake at P149 Duty for P169 time after passage of P168 time.)
Apply brake immediately before the solenoid for impact sound reduction reaches the stroke end when the
touch back solenoid is deactivated.
(Apply brake at P170 Duty for P75 time after passage of P74 time.)

If the memory switch described above is changed, multi-layer stitches of automatic reverse are not
matched each other, and therefore, change in the initial position of the automatic reverse is also
necessary.
To match the stitches, change the values of memory switches: P18, P19, P25, P26, P32, P33, and P77.
