AUTOMATIC MODE
When the RSTC is in automatic mode (status display
indicates “Auto”) the tension setpoint is adjusted by
turning the Tension Adjust knob. Turning the knob
clockwise will increase the setpoint and turning the knob
counterclockwise will decrease the tension setpoint.
Turning the knob will cause the ROP display to change
from the RSTC Status screen to the Job Setup screen (See
Figure 8). Continue turning the knob until Web Tension
Setpoint is set to the desired tension value. If the knob
is left stationary, the ROP display will return to the RSTC
Status screen after a short delay.
Web tension is indicated by the TENSION display (See
Figure 7). The bar graph display indicates web tension
magnitude as a percentage of the RSTC’s maximum
tension setpoint value entered during RSTC setup.
