At the same time, have the other worker

8. Roll Photosensors Sensitivity
Adjustment
The roll sensors consist of two groups of four
sensors each (Figure 7-51). They are located
directly above the clutch-brake rollers; four over
the right rollers and four over the left rollers.
Required Tools
7/16” wrench, thin slotted screwdriver
Perform only when the unit is OFF
with power connected.
Use extreme caution.
Turn power ON at the main disconnect
switch.
Press the green START button.
Press any of the red Safety STOP but-
tons.
Working on one set of sensors at a time,
work a small piece of flatwork between the
clutch-brake rollers so that a few inches
of material is visible (Figure 7-51, A).
Both red and green LEDs on the sensors
should be lit.
By hand, turn the clutch-brake rollers;
keeping an eye on the photosensor LEDs
as you do so.
When only about 1/8” of material is show-
ing evenly, the red LEDs should extinguish
while the green remain lit (Figure 7-51,
B).
If the red LEDs go out too soon, sensitivity
is low; if they do not go out at all, sensitiv-
ity is too high.
Adjust sensitivity so the green LEDs are
bright and steady all the time and the red
LEDs shut off an on together when only
about 1/8” of material is in view between
the clutch-brake rollers.
Re-start the unit and test the adjustment by
processing several pieces of flatwork.
