PRODUCT DESCRIPTION 3
3.2.2 Product characteristics
The PSS Print Detector is primarily used in the packaging industry for verifying the pres‐
ence of prints, such as best-before dates, serial numbers, or 2D codes. They can, how‐
ever, also be used in any 1D pattern verification application.
The PSS compares a taught-in pattern with the following patterns; checks that they
match and checks for 100% correspondence to reduce deviations in contrast or length.
The sensitivity level, i.e., a print that is yet to be recognized as good quality, can be set
by the user.
10 - 30 coarse: Print is present.
•
40 - 60 medium: Print is present, but the quality is poor.
•
70 - 90 fine: Print is present, the quality is good, but details are missing.

6 OPERATION
6.7 Trigger
Figure 5: Trigger
For operation, the sensor needs a trigger signal regarding the length of the print to be
evaluated for signaling the reading window. This is supplied to the sensor via Pin 5. The
start of the reading window is signaled by the rising edge of the trigger signal, the con‐
trol panel cannot be operated during this time. The end is signaled by the falling edge.
The associated output state change is present no later than 10 ms after the falling
edge. The process quality (quality of print) is displayed. When checking the print on
packaging and other objects, we recommend generating the trigger signal via a photo‐
electric sensor; if continuous material is used, the signal can be generated via a control
or a contrast sensor.

External teach-in
The external teach-in and the trigger input can be synchronized for the teach-in process
as follows:

Incorrect teach-in
In the event of a teach-in failure, Err appears on the display and the Q LED and TCH LED
flash.
Control panel locked
If the device is undergoing an internal process (e.g., reading or storing parameter sets
or teaching-in via IO-Link), the control panel is locked and the device shows “bSY” on
the segment display.
Short-circuit and overcurrent detection
In the event of a short-circuit and overcurrent, Err appears on the display and the Q LED
flashes.
Live measured value (run mode)
In run mode, the device displays the quality compared to the reference print in %.
The higher the value, the better the correspondence with the taught-in print.

Cleaning the light emission window
NOTICE
Damage to the light emission window!
Reduced reading performance due to scratches or streaks on the light emission win‐
dow!
Clean the light emission window only when wet.
b
Use a mild cleaning agent that does not contain powder additives. Do not use
b
aggressive cleaning agents, such as acetone, etc.
Avoid any movements that could cause scratches or abrasions on the light emis‐
b
sion window.
