Chapter "Operator controls and connection terminals (Page 170)".
3UG4582: By operating the rotary button, the tens position of the threshold for undershoot
2)
(R.1) can be selected.
3UG4582: By operating the rotary button, the units position of the threshold for undershoot
3)
(R.2) can be selected
3UG4583: By operating the rotary button, the tens position of the threshold for undershoot
4)
(R1.1) can be selected.
3UG4583: By operating the rotary button, the units position of the threshold for undershoot
5)
(R1.2) can be selected
3UG4583: By operating the rotary button, the tens position of the threshold for undershoot
6)
(R2.1) can be selected.
3UG4583: By operating the rotary button, the units position of the threshold for the insulation
7)
resistance R2.2 can be selected
The threshold is derived from the sum of the two set values. If, for example, threshold R.1-value
is set to 70 and threshold R.2-value is set to 8 on the 3UG4582, threshold R corresponds to
78 kΩ.
