Malfunctions in Reading mode: reading trigger errors
¾
Check whether the "Device Ready" LED lights up.
If the LED does not light, see
CLX in stand-alone configuration
Malfunction
Possible cause
Remedy
1. Trigger mode:
Sensor input
(external sensor).
The CLX cannot be clocked:
– the "Sensor" LED does not light up
– the red scan line does not appear
•
Sensor not connected or connected to
incorrect switching input.
•
If sensor supplied by CLX: sensor not
connected to ground potential.
•
Incorrect reading pulse source para-
meterized in the CLX.
•
Photoelectric switch not aligned with the
reflector (photoelectric proximity switch/
inductive sensor not dampened).
•
Connect sensor to "Sensor" switching
input. Check sensor wiring (see
). Measure output signal on
sensor.
•
Insert jumper between pin 5 and pin 15.
•
In the "CLV-Setup" program: choose the
D

S
OURCE
section: is Sensor input
selected? (active high: reading pulse
starts when power applied)
•
Align sensor.
Check functioning.
2. Trigger mode:
Serial interface
The CLX cannot be clocked:
– the "Sensor" LED does not light up
– the red scan line does not appear
•
Incorrect reading pulse source parame-
terized on the CLX.
•
The CLX is not receiving any command
strings to start the reading interval on the
data interface.
•

3. CLX does not respond to an
external signal that ends the reading
pulse (sensor input, serial interface)
Incorrect end of reading pulse para-
meterized on the CLX.
