2. TC920V UNIT DESCRIPTIONS
2.1 FRONT PANEL
The front panel is the primary means of controlling and monitoring the TC920V by the machine operator. From the front
panel, the machine operator can monitor the output level, tension measurement, and machine state. The operator can set
the tension set point or run the TC920V in manual mode. Setup and calibration of the TC920V is not directly accessible
from the front panel, limiting the operator’s control of the unit during operation of the machine.
