Operation

6.5 Operating modes and outputing the reading result

The following CLV490 operating modes/functions (and more) can be selected in CLV-Setup:

Standard operating mode:

• Reading mode

For setup:

• Percentage evaluation

• Adjusting mode

For adapting the device to the application at hand:

• Configuring (parameterizing) the CLV490.

See Chapter 6.4.1 Configuring the CLV490 via the user interface of CLV-Setup,

Page 6-5

• Background teach-in

• Show background

• Show RA-limits

For monitoring purposes/trouble shooting:

• Background analysis

• I/O monitor in incremental pulse

• Display and edit operating data

• Reading diagnosis

• Monitor host interface

• Auxiliary input

• Self-test

6.5.1 Reading mode (standard operating mode)

The CLV490 performs a self-test after it has been switched on. It switches to Reading mode

("Device Ready" LED lights up). In the default setting the "Sensor" switching input is the

(external) trigger source of the reading pulse. The reading result is output by the CLV490 at

the end of the reading pulse via the host interface (default setting) and auxiliary interface.

Depending of the configuration, the "Result 1" to "Result 4" switching outputs become live

for the predefined pulse length when defined events occur during the reading process (e. g.

Good Read).

The reading result of the auxiliary interface can be displayed in the CLV-Setup Terminal

Emulator. The CLV490 auxiliary interface must be set to the Reading Diagnosis mode for

this purpose. This mode is selected for the default setting. The reading result of the auxiliary

interface has a fixed, invariable format.

The Reading mode can be called up by choosing V

IEW in the menu bar or via the Terminal

Emulator.

Line scanner with oscillating mirror:

In the Reading mode the CLV490 deflects (by default) the scan line about the position

CW = 50 at a frequency of 1 Hz and a maximum angle of ±20°. 50 CW corresponds to an

angle of deflection of 105°.
