DETECTING SIGNAL LEvEL

This control is factory set for normal operation and in 
most applications does not require field adjustment.

If the web or sheet run in a machine is consistently less than 
0.002 In. [0.05 mm] and the Normal Run Indicator LED will 
not come on (the Web Break Indicator LED stays on), it may 
be necessary to adjust the detecting signal level.

If the web or sheet used in the machine is over 0.031In. 
[0.8 mm] and the Normal Run Indicator LED will not 
come on (Double Feed/Splice Indicator stays on), it may 
also be necessary to adjust the detecting signal level.

1.  Select Mode 

or 

as appropriate for the machine 

speed.

2.  Have a sample of the problem material on hand.

3.  Set the Power Switch to 

ON

.

AuTOMATIC RESET TIME SELECTION

The factory preset for Automatic Time Selection is ap-
proximately 2 seconds.  This time can be changed to 
anywhere from 0.2-6 seconds with VR1, located on the 
printed circuit board.  To select a time other than the fac-
tory preset time adjust VR1 as follows:

1.  Turn power OFF using the Power Switch located on 

the front panel of the PC210 (See Figure 9).

2.  Remove the four screws and Top Cover from the 

PC210 (See Figure 9).

3.  Turn power ON using the Power Switch located on 

the front panel of the PC210 (See Figure 9).

4.  Locate VR1 on the main printed circuit board (See 

Figure 10).

5.  Adjust VR1 until the desired reset time is selected 

(See Figure 11 for approximate time delay positions).

6.  Test the reset time by inserting a splice or double 

sheet into the Sensor until the Web Splice/Double 
Sheet-Feed triggers with the Reset Selection in 
AUTO; then, observe the time until the relay resets.

7.  Turn power OFF using the Power Switch located on 

the front panel of the PC210 (See Figure 9).

8.  Replace the Top cover and the four screws (See 

Figure 9).
