b) Be sure the SW101 switches on the Control board are correctly set. Switch 3 must be open and
switch 4 must be closed.
c) On the Control board, turn the TEN TRIM pot.(RT105) to 0. (fully counterclockwise)
d) Remove the web and run the machine at normal speed. Using a hand-held tachometer, measure
the surface speed of a driven roll running at machine speed. Then measure the surface speed of
the driven nip roll that is controlled by the SteadyWeb. Adjust the LTACH Span pot. on the TACH
card to match the nip roll speed to the machine speed.
e) Set the TEN TRIM pot. to 20%.
Note
: The TEN TRIM should not be set high. It could cause tension transients at start up and
instability while running. A setting of 10 to 20% is usually ideal.
f) Go back to Section 7.2, step c) to continue tuning.
