6.3 Standard display in the operating mode
The values of the EDS44x-L are mainly displayed via the connected ISOMETER® and the
values of the EDS44x-S are only displayed via the connected ISOMETER®.
6.3.1 Standard display EDS44x-S
In the operating mode, the EDS44x waits for the insulation fault location to start. The
green operation LED "ON" lights up. All messages are indicated via the connected ISOME-
TER®.
6.3.2 Standard display EDS44x-L
In the operating mode, the EDS44x waits for the insulation fault location to start. There is
no alarm on any of the 12 channels. The EDS44x-L displays its slave address on demand.
Only the green operation LED "ON" lights up. While the device communicates or the in-
sulation fault location is in progress, the "COM" LED flashes additionally.

6.4 Alarm messages
Alarm messages of the EDS44x-L are directly indicated on the control panel of the device,
while the alarm messages of the EDS44x-S are displayed on the respective ISOMETER®.
Possible causes of an alarm message are:
• Insulation faults, residual current exceeded, device errors, measuring current trans-
former faults or measuring current transformer connection faults and an interfer-
ence.
6.4.1 Insulation fault (ALARM I
ΔL
)
If an insulation fault is detected on a measuring channel, (EDS function), the "ALARM I
L
"
LED (main alarm) and the LED of the channel on which the fault was detected, lights up.
In addition, the fault is indicated on the display of the ISOMETER®.
6.4.2 Residual current exceeded (ALARM I
Δn
)
The residual current flowing through the measuring current transformer is continuously
measured and displayed. If the residual current is too high, a successful insulation fault
location is not possible.
This function of the EDS441x is only suitable for frequencies in the 50/60
Hz range.
