10.1
(1.8.1.4) Function
The parameters for the function of the digital inputs of the ISOMETER® can be set
differently:
10.1
(1.8.2) Digital 2
Refer to
10.1
(1.8.3) Digital 3
Refer to
10.1
(1.9) Outputs
The ISOMETER® provides a total of six outputs.
The following parameters can be set for the outputs:
10.1
(1.9.1) Relay 1
The following parameters can be set for each relay:
10.1
(1.9.1.1) TEST
The functional test of the relay can be activated or deactivated. This only applies to the
manual test and not to the cyclic device self test:
10.1
(1.9.1.2) Relay mode
The relay mode can be adapted to the application:
•off
Digital input without function
•TEST
Device self test
•RESET
Reset of fault and alarm messages
•Deactivate
device
The device DOES NOT measure the insulation resistance, the mes-
sage
Device inactive
appears on the display.
The IT system is NOT being monitored!
•Start initial
measurement
All recorded measurements are discarded and a new measurement
is started
•on
The manual test checks the switching function of the relay
•off
The manual test does not check the switching function of the relay
•N/C
Normally closed- N/C operation contacts11-12-14 / 21-22-24
(in fault-free condition, the alarm relay is energised).
•N/O
Normally opened - N/O operation contacts 11-12-14 / 21-22-24
(in fault-free condition, the alarm relay is de-energised).
10.1
(1.9.1.3) Function 1
Up to three functions can be assigned to one output. The functions are linked to an OR
operator:
Select the appropriate setting for function 1. The following parameters can be set.
10.1
(1.9.1.4) Function 2
Refer to
.
•off
The function is not used.
•Ins. Alarm 1
The status of the output changes when the value falls below the set
response value R
an1.
•Insulation fault
+ DC shift error
The status of the output changes when the value falls below the set
response value R
an2.
•Connection fault
The status of the output changes when one of the following connec-
tion fault occurs:
• No low-resistance connection between the line conductors.
• No low-resistance connection between the terminals E and KE to
earth (PE).
• The load connected to the current output is too low
• The load connected to the current output is too high.
• Load on X1 too high.
•Device fault
The status of the output changes in the event of an internal device
fault.
•Common alarm
The status of the output changes on the occurrence of any alarm
and fault messages
(Ins. alarm 1 & 2, DC- / DC+ alarm, symmetrical alarm, connection
and device faults).
•Measurement com-
plete
The status of the output changes at the end of the initial
measurement.
•Device inactive
The status of the output changes when the device has been
deactivated via a digital input or the control menu.
