8.2 (1.5) Inputs
The ISOMETER® provides 2 digital inputs (I1, I2) that are freely configurable.
8.2 (1.5.1) Digital 1
The following parameters can be set for the digital input:
8.2 (1.5.1.1) Mode
The operating mode for the digital input can be set to the following values:
Active high An event is carried out on the rising edge of the digital input (low to
high).
Response time t(on)/t(off ) after a switch-on signal.

8.2 (1.5.1.4) Function
The parameters for the function of the digital inputs of the ISOMETER® can be set
differently:
•off Digital input without function
•TEST Device self test
Reset of fault and alarm messages
•RESET
The device DOES NOT measure the insulation resistance,
•Deactivate device
the message
The IT system is NOT being monitored!
The device uncouples itself from the system to be moni-
tored through an internal system isolating switch.
•Insulation fault The insulation fault location is started. For this purpose,
the digital input must be active.

8.2 (1.5.2) Digital 2
Refer to "8.2 (1.5.1) Digital 1".
8.2 (1.6) Outputs
The ISOMETER® provides a total of 3 alarm relays.
The following parameters can be set for relay 1 and relay 2:
8.2 (1.6.1) Relay 1
The following parameters can be set for the relay:
8.2 (1.6.1.1) 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:
•on The manual test checks the switching function of the relay
The manual test does not check the switching function of the relay
•off
8.2 (1.6.1.2) Operating mode
The relay mode can be adapted to the application:
Normally closed - N/C operation contacts11-12-14/
•N/C
21-22-24 (The alarm relay is energised during normal operation).
Normally open - N/O operation contacts 11-12-14/
•N/O
21-22-24 (The alarm relay is de-energised during normal operation).
8.2 (1.6.2) Relay 2
Refer to "8.2 (1.6.1) Relay 1".
