7.1.3.2 General Functions
Main function
MAIN: Hold time dyn.param.
018 009
Fig. 3-39
Setting for the hold time of the "dynamic parameters". After switching to the
"dynamic" thresholds, the latter will remain active in place of the "normal"
thresholds during this period.
MAIN: Syst.IN enabled USER
018 008
Fig. 3-38
Enable/disable the DTOC or IDMT residual current stages.
MAIN: Block tim.st. IN,neg
017 015
Fig. 3-47
This setting defines whether a blocking of the residual current stages should
take place for single-pole or multi-pole phase current startings.
MAIN: Gen. starting mode
017 027
Fig. 3-48
This setting defines whether the triggering of the residual current stages I

are automatically excluded from the formation of the trip command.
MAIN: Op. mode rush restr.
017 097
Fig. 3-40
Setting the operating mode of the inrush stabilization function.
MAIN: Rush restr. active
017 093
Fig. 3-40
MAIN: Rush I(2*fn)/I(fn)
017 098
Setting for the operate value of inrush stabilization.
MAIN: I> lift rush restr.
017 095
Fig. 3-40
Setting the current threshold for inactivation of inrush stabilization.
MAIN: Suppress start. sig.
017 054
Setting of the timer stage for the suppression of the phase-selective
startings and of the residual and negative-sequence system starting.
MAIN: tGS
017 005
Fig. 3-48
Setting for the time delay of the general starting signal.
Definite-time overcurrent
protection
DTOC: General enable USER
022 075
Fig. 3-72
Disabling or enabling the definite-time overcurrent protection function.
Inverse-time overcurrent
protection
IDMT: General enable USER
017 096
Fig. 3-81
Disabling or enabling the inverse-time overcurrent protection function.
Limit value monitoring
LIMIT: General enable USER
014 010
Fig. 3-93
Disabling or enabling limit value monitoring.
LIMIT: I>
014 004
Fig. 3-93
Setting for the operate value of the first overcurrent stage of limit value
monitoring.
LIMIT: I>>
014 020
Fig. 3-93
Setting for the operate value of the second overcurrent stage of limit value
monitoring.
