Siemens 6MD85 - Settings

•
Default setting (_:14011:148) VT supervision time delay = 10 s
With the VT supervision time delay parameter, you set the time for which exceeding the voltage
supervision threshold does not lead to a blocking.
Parameter: Circul. current blocking
•
Default setting (_:14011:149) Circul. current blocking = on
With the Circul. current blocking parameter, you switch the supervision of the circulating reactive
current off or on.
Parameter: Circul. current threshold
•
Default setting (_:14011:150) Circul. current threshold = 150 %
With the Circul. current threshold parameter, you set the level at which the supervision must be acti-
vated.
Parameter: Circul. current time delay
•
Default setting (_:14011:151) Circul. current time delay = 30 s
With the Circul. current time delay parameter, you set the time for which exceeding the threshold
value of the circulating reactive current supervision does not lead to a blocking.
