After connecting VEGABAR 52 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).
