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 failure signal
After the run-up period (specification see "Technical data"), the instru-
ment delivers an output signal of 4 ... 20 mA. The value corresponds
to the actual level as well as the settings already carried out, e.g.
factory setting.
