Relationship between Uci, Uo1, UV, IV and Uo1/Uo nom ver-
sus time.
1 VME request: minimum 4 ms
2 tlow min = 40...200 ms, typically 80 ms
3 UV level not dened at Uo1 < 2.0 V
4 The V signal drops simultaneously with the output voltage if the
pull-up resistor
RP is connected to Vo1+.
The V signal remains high if
RP is connected to an external
source.
