5.6 Switch-on phase

After VEGASON 61 is connected to voltage supply or after voltage

recurrence, the instrument carries out a self-check for approx. 30

seconds. The following steps are carried out:

•

Internal check of the electronics

•

Indication of the instrument type, the firmware as well as the sen-

sor TAGs (sensor designation)

•

Status byte goes briefly to fault value

Then the current measured value will be displayed and the corre-

sponding digital output signal will be outputted to the cable.

Switch-on phase

The values correspond to the actual measured level as well as to the settings

already carried out, e.g. default setting.
