One Shot or Phase
Mode using the Input
1 (External Trigger) or
Input 2:
the ”TRIGGER” LED is
not blinking while the
External Trigger is
switching.
Check if you are referring to the 17-pin connector or to the CBX
spring clamp connectors.
Is the sensor connected to Input 1 or Input 2?
Is power supplied to the photo sensor?
For NPN configuration, is power supplied to one of the two I1 or
I2 signals (A or B)?
For PNP configuration, is one of the two I1 or I2 signals
grounded (A or B)?
Are the photo sensor LEDS (if any) working correctly?
Is the sensor/reflector system aligned (if present)?
On the Reading Phase step check the Input 1 or Input 2
Debouncing Time
parameter setting.
On the Reading Phase step check the settings for
Acquisition
Trigger, Reading Phase-ON,
and
Reading Phase-OFF
parame-
ters.
One Shot or Phase
Mode using serial
trigger source:
the ”TRIGGER” LED is
not blinking.
On the Reading Phase step check the settings for
Acquisition
Trigger, Reading Phase-ON,
and
Reading Phase-OFF
parame-
ters.
Are the COM port parameters (
Baud Rate, Parity, Data Bits, Stop
Bits
) correctly assigned?
On the Reading Phase step check the settings of
Acquisition
Trigger String, Reading Phase-ON String,
and
Reading Phase-
OFF String
parameters.
Is the serial trigger source correctly connected?
Phase Mode:
the ”TRIGGER" LED is
correctly blinking but
no image is displayed
in the DL.CODE win

dow.
Is the Phase frequency lower than the maximum frame rate?
Continuous Mode:
the ”TRIGGER” LED is
not blinking.
Verify the correct software configuration settings.
Any Operating Mode:
the ”TRIGGER” LED is
correctly blinking but
no result is transmit

ted by the reader at
the end of the reading
phase collection.
Check the Code Collection parameters on the Reading Phase
step and the Data Formatting parameters on the Data Format

ting step.
Image not clear: verify the Focus procedure
Image focused but not
