5.5 Switch-on phase

After connecting VEGASON 63 to power supply or after a voltage

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

seconds:

Internal check of the electronics

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

sor TAGs (sensor designation)

Output signal jumps briefly (approx. 10 seconds) to the set fault

current

Then the corresponding current is outputted to the cable (the value

corresponds to the actual level as well as the settings already carried

out, e.g. factory setting).
