9. Settings

The settings of the ISOMETER® are explained in the order of the device menu.
9.1 1.0 Alarm settings
The limit values for the insulation resistances of alarm 1 and alarm 2 can be specified in
the alarm settings menu and adjusted to the profile of the ISOMETER®. If you have acti-
vated the password query in the device menu (refer to
enter the device password in order to change the settings.
You can adjust the following functions:
9.1 (1.1) Insulation alarm
In the Insulation alarm menu, the ISOMETER® limit values for alarm 1 and alarm 2 can be
set. Activation or deactivation of the two alarm levels R
illustrated in the following graphic:
An alarm will become inactive as soon as the hysteresis of the set operating value is ex-
ceeded.

9.1 (1.2) Profile
Adapt the area of application of the ISOMETER® to your system profile. For a description
of the profiles, refer to "Device profiles" auf Seite
The following can be selected:
•Power circuits
Suitable for most IT systems.
•High capacitance Suitable for system with high leakage capacitances.
Limit of the measuring range: 200 kΩ
•Inverter > 10 Hz Suitable for systems with dynamic frequency control by
inverters in the range 10 to 460 Hz.
•Inverter < 10 Hz Suitable for systems with extremely low frequency control
in the range 1...460 Hz.
•Fast 2000 μF Suitable for systems with very high leakage capacitances,
e.g. in large-scale photovoltaic systems.
Limit of the measuring range: 50 kΩ
9.1 (1.3) Fault memory
Automatic reset of inactive faults at the outputs
(relays 11-12-13, 21-22-24, 31-32-34):
•on If a fault becomes inactive, the programmed outputs remain
in fault condition until they are reset manually.
•off If a fault becomes inactive, the programmed outputs auto-
matically change the state.
