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 3 or 6 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).
