7. Parameterization via the BMS bus
7.1 Parameter
7.1.1 Tabel overview
7.1.2 Parameter description
• Channel 1 ( Z
an
/kΩ): Response value for insulation measurment (active method)
This parameter defines the response threshold for the active measurement procedure. If the insulation
value
Z
e
measured by the ISOMETER® exceeds the response value Z
an
, then the ISOMETER® triggers an
alarm.
Depending on the system leakage capacitance C
e-Anlage
and the system insulation resistance R
e-system
,
the response value Z
an
may not exceed a certain value so that the ISOMETER® enters the normal opera-
ting condition taking into account the hysteresis (no alarm signal). The following diagram shows how
high the response value
Z
an
can be set for different insulation conditions of the installation.
