Checking and Cleaning Lens Window(s)
Sometimes dirt, oil, or another substance can get on the plastic lens window on each optic
head, which could block a light beam and prevent press operation. This might be the case
when the red light is on at the control and receiver with no objects in the light field.
If your operation is particularly dusty, oily, or smoky, general build-up of dirt could also
affect operation. Both problems are easily corrected by cleaning the lens window with a
clean, particle-free cloth. Use a mild solution of detergent and water, a solvent (such as
acetone), or an isopropyl-based cleanser. Make sure you avoid excessive rubbing.
Checking Alignment
Shadows can go out of alignment if the universal mounting brackets have been bent, if a unit
has been hit (by a die cart or forklift, for example), or if mounting bolts have loosened,
allowing the units to move slightly. You may have an alignment problem if the red indicator
light stays on even with the light field clear.
To check alignment, first loosen one optic head's universal mounting brackets at both ends.
Then, rotate the head back and forth to see if this generates a green light. See "Aligning and
tightening down your Shadows" in Chapter 2 for alignment procedures.
If that does not solve the problem, remove either the receiver or transmitter (whichever is
easier) from its bracket, and move it right up to the other unit —within 6 to 11" (15.2 to 27.9
cm). Make sure that the connection to the control remains intact as you move it closer.
Aim that unit so it is pointing directly at the mating optic head exactly in a straight line. See
the alignment information and diagrams in Chapter 2 if you are not sure what this means.
Shadows will always align at this close range if working properly.
Alignment Problem or Bad Phototransistor
Observe the lights at the receiver and the control as you test Shadow. If the green light
comes on at close range, alignment may be the problem. However, you have to make one
more check to be sure. Place both units on a bench so that they are aligned and the green
light is on. Now start moving one unit away from the other, making sure you keep the beams
aligned.
If you find the red lights come on at further distances, but the green lights come on at close
range, the problem may be a bad phototransistor or LED. Phototransistors are the devices
inside the receiver that detect the light beams. When one becomes weak, it can detect a light
beam close up, but not at greater distances. LEDs send the light from the transmitter to the
phototransistors at the receiver. If they are weak, they cannot generate enough light at greater
distances. If you suspect a bad LED or phototransistor, contact Wintriss Tech Support
immediately to discuss return of the unit.
If the green lights stay on even as you move the units apart, then your mounting on the ma-
chinery is the problem. A unit may have been hit and moved out of alignment or a bracket
may have been bent, shifting the unit out of alignment. Check for the cause of misalignment
and correct it. See Chapter 2 for proper alignment procedures.
