If the Web thickness is less than 0.002
In. [0.05 mm] thick, the Web Break
Indicator will glow. Be sure the splice
is more than 0.002 In. [0.05 mm] thick
or the PC210 will not detect it.

Lack of response is often caused by
the tape being half or less than half
the thickness of the web when using
type B single butt splice. This situation
can also be corrected by changing to
a type A or C splice by using a thicker
tape (See Figure 9).
