Description

k-Setting
factor for extending the time constant when the unit is stationary.
The unit is assumed to be at a standstill when a logical “1” is
being applied to the binary standstill I/P and a low current is
being measured at the same time (less than approx. 0.005 IN
in the case of metering c.t. cores or 0.05 IN in the case of
protection c.t. cores).
NrOfPhases
defines the number of phases monitored.
CurrentInp
defines the current input channel.
All current I/P’s may be selected.
The first channel (R phase) of the group of three selected
must be specified in the three-phase mode.
IB-Setting
Reference (base) current for compensating a difference in
relation to IN.
Stillst.-Inp
for detecting when the unit is at standstill and switching to a
longer time constant for taking account of the slower cooling.
(binary address)
(FFALSE, TTRUE, binary input or output of a protection
function)
BlockInp
Binary address used as blocking input.
(FFALSE, TTRUE, binary input or output of a protection
function)
Warning
Output for signalling an alarm
(signal address)
Trip
Output for signalling tripping
(signal address)
TimeConstant
defines the thermal model for calculating temperature rise.
Settings:
> 0 1st. order thermal model for which the thermal time
constant has to be entered.
Settings between 0.1 min and 1.0 min are not permitted.
= 0 Thermal model according to table entered.
