Commissioning
7. Commissioning
7.1 General initial commissioning process
1.
Check that the ISOMETER® is properly connected to the system to be monitored.
2.
Connect the supply voltage to the ISOMETER®. The ISOMETER® then performs a 4-
step self test during which the alarm relays are not checked. After completion of the
test, the measured insulation resistance is shown on the display. If the value exceeds
the response values indicated in the lowest line of the display, the message "OK" will
additionally be displayed.
3.
Check the ISOMETER® in the system being monitored, e.g. using a suitable resistance
to earth.
7.2 Recommissioning
If the device has already been put into operation before, the self-test will be started short-
ly after the supply voltage has been connected.
The device settings can also be carried out via the commissioning-wizard, which can be
manually started via the menu path:1
Menu/Device settings/Commissioning
This menu can be used to modify settings made previously.
For customer-specific configured devices, the commissioning wizard
might be deactivated and cannot be run. In this case, the device is preset.
However, the commissioning wizard can be started as described at
Observe device status!
The device is in an alarm state until initial commissioning has been
completed.
Observe the device status!
The device changes from the alarm state to normal state after
completing initial commissioning and initial measurement by ad-
hering to the response values set.
