Heater control

The two heater-controls above the control panel are equal. The upper heater control
regulates the temperature of the corresponding upper main roller. The lower heater control
is for the bottom main roller heater.
Figure 10: Heater-control section
The heat is turned ON and OFF by the 0/I switch (1). Press I to turn the heat ON. The
actual roll temperature (4) is shown on the control display. The heat has a factory defined
temperature range. Within this range the roller temperature can be regulated. The
temperature set point is displayed when the SEL (5) button is pressed, and changed by
pressing the up (6) or down (7) buttons.
Note: When the temperature set point is being displayed, the light by SV (3) is lit. Press
the SEL (5) button again to return to the actual temperature or the the display will return
back automatically in about 20 seconds.
If the actual temperature is lower than the set point temperature, the heat is turned ON and
C1 (2) is lit.
Note: The heated roller needs time to reach its set temperature (e.g. from room
temperature to maximum takes approximately 1 hour). It is recommended to let the
machine run at a low speed, to avoid uneven hot spots.
Cooling device (optional)
The optional cooling device is switched ON and OFF by the 0/I switch below the control
panel.
