INSTRUCTION MANUAL
The forked ultrasonic sensor for label detection works by the difference of
material width inside the sensible area.
The sensor is able to detect paper, plastic (transparent type too) and metallic
label on paper, plastic and metallic support tapes.
CONTROLS
STATUS LED (YELLOW)
The yellow LED ON indicates output activation.
MODE LED (GREEN)
In working mode, the green LED MODE is on.
The MODE LED shows the phases of the calibration and NO/NC toggling
procedures (see the following chart).
The MODE LED is quickly blinks in three conditions:
1- if the sensor is not able to do a calibration,
2- if the SET push-button or the REMOTE input are activated more than 60
sec,
3- if the sensor detects a short-circuit condition on the outputs.
To skip from the conditions 1 and 2, it is necessary to press SET or activate
REMOTE briefly, then the sensor restores the last valid calibration.
In case of condition 3, it is necessary to remove the short-circuit cause.
To start the LABEL calibration procedure press SET or activate REMOTE and
deactivate them when the MODE LED is on for the first time (1s < Tp< 4s).
To start the OFFSET regulation procedure press SET or activate REMOTE
and deactivate them when the MODE LED is off for the second time
(4s < Tp < 7s).
To toggle the NO/NC output function press SET or activate REMOTE and
deactivate them when the green LED is on for the second time
(7s < Tp< 15s).
To skip any operations, release SET or deactivate REMOTE when the green
LED is off, after 15s.
SET PUSH-BUTTON
Press SET push-button to activate acquisition.

NOTE 1:

proportional to the size of the
short target to detect.
Example:
Speed = label gap / min. detection
time = 2 mm / (2 x 1 ms) = 1 m/s = 60
m/min
NOTE 2:
The width and the placement of the tape in the fork, must to cover always all the dashed
area drawn around the sensing point.

OFFSET REGULATION (SRX3-5-US-3)
At the SET release or REMOTE deactivation, during the second switch off
LED MODE phase, the device enters in the manual OFFSET regulation
mode, shown by a slow blink on the MODE LED.
The OFFSET regulation is the adjustment of the threshold value used to
discriminate the signal.
In the OFFSET regulation mode the outputs and the status LED work like in
the working mode.
After 10 s of no operations on SET or REMOTE, the OFFSET manual
regulation mode is stopped.
The variations are saved, for restoring at the next power-on.
The OFFSET manual regulation mode is executed by pressing SET or
activating REMOTE. The sensor will do the first five variations at the speed of
1/sec, the second five variations at the speed of 2/sec and the next variations
at the speed of 5/sec, up to the SET or REMOTE deactivation or up to the
reaching of minimum or maximum OFFSET value.
Each OFFSET variation is shown by a blink on the green LED.
To choose the variation mode between increment or decrement of the
OFFSET value, press SET or activate REMOTE twice rapidly (double click),
in this way the sensor toggles between the two modes at each double click.
At the end of the double click the chosen mode is shown by 2 s of LED OFF
in increment mode and 2 s of LED ON in decrement mode.
At each OFFSET manual regulation startup the sensor activates the
increment mode, while the chosen mode remains activated up to the exit of
the OFFSET manual regulation procedure.
With increment mode and SET or REMOTE activation, the MODE LED is
OFF and the pulse variations are ON.
With decrement mode and SET or REMOTE activation, the MODE LED is ON
and the pulse variations are OFF.
At the end of the label calibration, the sensor has an operative threshold.
It is suggested to do:
- an OFFSET increment to increase the label position variations tolerance in
the sensing area,
- an OFFSET decrement to improve the gap detection with little sizes and
high speed tape movement.
NO – NC WORKING MODE
At the SET or REMOTE deactivation, after the second time MODE LED light
on phase, the device toggles the NO/NC function of the output and the
STATUS LED.
The NO/NC output function is saved, for the restoring at the next power on.
NO mode: outputs and STATUS LED are activated on the label.
NC mode: outputs and STATUS LED are activated with the label gap.
WORKING MODE NOTE
For the correct label detections, the tape must be taut and on the carriage, in
calibration and working mode.
Press SET or activate REMOTE at the power on for more than 3 s to restore
the default working condition (calibration for transparent tape and label and
NO output mode), release SET or deactivate REMOTE during the double
blink phase on the MODE LED.
