A fter connecting VEGAWELL 52 to power supply or after a voltage
recurrence, the instrument carries out a self-check:
l I nternal check of the electronics
l
4 … 20 mA output jumps to the failure signal
A fter the run-up period (specification see "Technical data"), the
instrument 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.
