When Full state (PS501: OFF, PS502:OFF) is detected, rewinding operation stops, and the
ERROR LED blinks and the LCD displays “Error Rewinder Full” on the operation panel.
Liner rewinding operation:
The rewinder motor turns to wind up the liner. During motor running, the blade of the motor
turns and the intermittent pulse is output from the photo interrupter PS701 of the “SA,
Rewinder Motor” to pin 176 (MTENC) of U1 (CPU).
The rewinder motor speed should vary according to the diameter of the wound liner to nearly
keep the winding speed constant. The rewinder motor speed is controlled by checking the
ON/OFF status of PS501 and PS502. That is, the rewinder motor speed is high for small
diameter and it is low for large diameter. This is accomplished by the MTREF signal sent to
U501 (Switching regulator) that produces +RW power supply for the rewinder motor. +RW can
be changed by changing the level of the MTREF signal. (Higher +RW turns the rewinder motor
faster.)
