N/O or N/C
operation
Optionally, N/O or N/C operation can be selected. Within the menus, the
English terms N.CLOSED resp. N.OPEN are used:
N.CLOSED:
normally closed
=>
N/C operation
N.OPEN:
normally open
=>
N/O operation
N/C operation means: In normal condition, the respective alarm relay of the
IR5002 is energized and is de-energized in fault condition.
N/O operation means: In normal condition, the respective alarm relay of the
IR5002 is de-energized and energized in fault condition.
For changing the operating principle of the alarm relay, select the respective
relay by using the UP and DOWN keys. RELAY1 is the alarm relay for
insulation faults at the positive conductor (positive fault), RELAY2 is the alarm
relay for insulation faults at the negative conductor (negative fault).
If, for example, the alarm relay 2. RELAY 1 is selected for the positive fault and
confirmed with ENTER, the cursor jumps to line 2. RELAY 1 and is positioned
before the designation N.CLOSED, as shown in the picture above.
By scrolling the UP and DOWN keys it is possible to select between
N.CLOSED and N.OPEN. Confirming with ENTER returns you to the
previous mask. From there you will return to the main menu.

Setting the
threshold of the
voltage
Select 5 ALARM SYST. VOLTAGE from the main menu to set the threshold of
the system voltage. If the value falls below the set threshold of the system
voltage, it will be signalled by the alarm relay K3 (N/C operation). Thresholds of
350 V and 100 V can be selected.
Attention: if the value falls below the set
threshold in the event of an insulation fault, no alarm will be actuated.
Setting the threshold to 100 V does not change the permissible operating range
of IR5002 from 350 to 800 V for the insulation monitoring function.
By positioning the cursor onto sub menu 2 and confirming with ENTER , the
cursor jumps to line 3 and is positioned in front of the value of the voltage.
