8.5.2 Malfunctions in Reading mode: reading trigger errors

¾ Check whether the "Device Ready" LED lights up.

If the LED does not light, see Table 8-5, Page 8-9.

CLV490 in stand-alone configuration

Malfunction Possible cause Remedy

1. Trigger mode:

Sensor input (external sensor).

The CLV490 cannot be clocked:

– the "Sensor" LED does not light up

– the red scan line does not appear

Reading mode "Start/stop" or

"Tracking ":

• Sensor not connected or connected to

incorrect switching input.

• If sensor supplied by CLV490: sensor

not connected to ground potential.

• Incorrect reading pulse source para-

meterized in the CLV490.

• Polarity of switching input inverted

• Incorrect debouncing of the switching

input parameterized in the CLV490.

• Photoelectric switch not aligned with the

reflector (photoelectric proximity switch/

inductive sensor not dampened).

• The object does not pass the reading

pulse sensor for trigger start with the

conveyor running.

• Connect sensor to "Sensor" switching

input.

Check sensor wiring (see Fig. 5-5,

Page 5-22).

Measure output signal on sensor.

• Insert jumper between pin 5 and pin 15

(CDM490: S 1 switch "SGND_GND")

• In the "CLV-Setup" program: choose the

EVICE CONFIGURATION tab, READING TRIG-

GER SOURCE section: Sensor input select-

ed? (active high: reading pulse starts

when power applied, active low: reading

pulse starts when power removed)

• See above.

• In the "CLV-Setup" program: choose the

EVICE CONFIGURATION tab, click the

EADING TRIGGER PARAMETERS button,

DEBOUNCING SENSOR section:

Time controlled: selected value too high?

Track controlled: incremental encoder

connected to "IN 4" switching input?

• Align sensor.

Check functioning

• Install reading pulse sensor in front of the

CLV490 in conveying direction. See also

Chapter 4.4.2 Mounting the external rea-

ding pulse sensor, Page 4-11 .
