(9) Rewinder motor temperature sensor (CL-S700R only)
The Rewinder motor temperature sensor is used to detect the temperature of the rewinder
motor. This sensor is a thermistor bonded to the rewinder motor. Since the resistance of the
thermistor changes according to the temperature change, the voltage at pin 11 (MTTH) of U1
(CPU) changes accordingly. The CPU senses the voltage at pin 11 to detect the rewinder
motor temperature.
Rewinding operation when the rewinder motor temperature rises:
When the temperature of the rewinder motor rises to 110
°C (230°F), printing/rewinding stops.
In this case, the ERROR LED blinks and the LCD displays "Alarm Rewinder Hot" on the
operation panel.
When the temperature of the rewinder motor falls below 100
°C (212°F), the LED stops blinking,
the LCD returns to the original display “On Line”, and printing/rewinding resumes.
