Indicators
The colour of the backlight indicates the operating status of the device.
Off:
No auxiliary voltage connected
Green:
Normal operation (Insulation resistance in healthy state)
Red:
Alarm (measured value below alarm response value,
device failure, connection failure)
Orange: Warning (measured value below pre-alarm response value,
test mode, Parameter set-up mode)
Actual value display
The actual insulation resistance „R
R
< 10 kΩ, the value in kΩ is displayed with 1 decimal place. With
E
values 10 kΩ ≤ R
< 500 kΩ the display shows the value without
E
decimal place, with values 500 kΩ ≤ R
ded to 10 kΩ. Insulation resistance values 1 MΩ ≤ R
are displayed in MΩ with one decimal place. If the resistance is
R
> 2 MΩ the display indicates ---- showing the value is higher the 2 MΩ.
E
In a DC Network an asymmetric insulation resistance to „+" or „-" is indi-
cated by displaying „R
+[kΩ]" or „R
E
By pressing the scroll buttons (Scroll-Up „" und Scroll-Down „") more
measured values can be shown. Another value is the mains voltage on
L(+)/L(-).This is indicated with „U
the type of network and voltage. If the unit is connected single pole to a
3NAC network the mains voltage cannot be measured. With this setting
the voltage value is not displayed. When manual reset is selected, the
display shows the minimum stored value of the resistance „R
„R
[kΩ]" after the value dropped below the response value also when the
M
value goes back to healthy state. The stored minimum value will only be
reset when acknowledging the stored Alarm signal (with the reset button).
Also the firmware version can be displayed.
All measured values are provided via Modbus. The actual insulation
resistance, and the stored minimum insulation resistance are transmitted
with one decimal place. The measured values are transmitted rounded
exactly as they are displayed on the device.
For insulation restistances RE > 2 MΩ the value 0xFFFF is transmitted.
