7.2.3 Error handling
If the displayed values do not correspond to the conditions of the installation after parameterization, R
e-Anlage
and C
e-Anlage
must be set again. Refer to the iso1685FR-Set quickstart for operating instructions.
If the parameters do not correspond with the conditions of the installation, an ohmic insulation value deviating
from R
e_Anlage
is output for R
e
instead of the real value after initial commissioning.If the value of R
e
cannot be
determined, a default value of 1 MΩ is output instead.
The following errors can lead to these deviating outputs:
• Incorrect parameterization of R
e_Anlage
:
Consequences: The value to be parameterized for C
e_Anlage
(= Ce to set) cannot be correctly determi-
ned. Error cases: a.) Ohmic insulation resistance of the installation is higher than the parameterized
value:
Output R
e
= 1 MΩ
Error handling: R
e_Anlage
and C
e_Anlage
must be parameterized again
b.) Ohmic insulation resistance of the installation is LOWER than the parameterized value: Output
R
e
= R
e
= 1 MΩ:
Error handling: R
e_Anlage
and C
e_Anlage
must be parameterized again
• Incorrect parameterization of C
e_Anlage
:
Consequences: The resulting ohmic insulation resistance value does not correspond to the expected
value of the installation.
Error cases:
a.) System leakage capacitance of the installation is HIGHER than the parameterized value:
Output R
e
≠ R
e_Anlage
Error handling: C
e_Anlage
must be parameterized again
b.)System leakage capacitance of the installation is LOWER than the parameterized value:
Output R
e
= 1 MΩ
Error handling: C
e_Anlage
must be parameterized again
