Electrical installation

3. Switch on the PC and power supply to the SICK Connection Module.

4. Set the communication parameters (see Chapter 10.6.3 Starting CLV-Setup,

Page 10-46).

Tip

In the default configuration, the auxiliary interface outputs the reading result in reading

diagnosis mode.

You can change the operating mode to M

ONITOR HOST INTERFACE, to MONITOR HOST INTERFACE 2,

UXILIARY INPUT or EXTERNAL DATA STRING INPUT on the AUXILARY INTERFACE tab in the "CLV-

Setup" program.

5.5.7 Connecting the "Sensor" switching input

If a reading procedure is to be triggered on the CLV490 by an external sensor, the reading

pulse sensor must be connected to the "Sensor" switching input. This trigger type is select-

ed in the default setting of the CLV490. Fig. 5-5 shows the connections for the "Sensor"

switching input. Table 5-23 contains the characteristic data for this input.

¾ Connect the reading pulse sensor as shown in Fig. 5-5.

Tip

You can change the switching mode (polarity, debouncing, response for first pulse after

power-up) of the "S

ENSOR" switching input on the DEVICE CONFIGURATION tab in the "CLV-

Setup" program.

¾ Click the R

EADING TRIGGER PARAMETERS button.

Enter the values in the dialog box displayed.

Perform a download to the CLV490.
