Switch-on phase

After connecting VEGAWELL 52 to power supply or after a voltage
recurrence, the instrument carries out a self-check:
•
Internal check of the electronics
•
4 ... 20 mA output jumps to the fault signal
After the run-up period (specification see " Technical data"), the
instrument delivers an output signal of 4 ... 20 mA. The value corre-
sponds to the actual level as well as the settings already carried out,
e.g. factory setting.
