trip

2nd. parallel star-point

MTR adjustment active

REs adjustment active

injection open-circuit internally

injection open-circuit externally.
IV. Measurements:

ground fault resistance Rfs

measurement transformer ratio MTR”

grounding resistor REs”.
Explanation of measurements:
Rfs:
Ground fault resistances between 0 and 29.8 k can be determined and displayed. A display of 29.9 k or 30 k indicates a ground fault resistance >29.8 k. A value of 29.9 k
or 30 k is displayed when there is no ground fault.
A whole number between 100 and 111 is displayed for the
fault code in cases when it is not possible to compute the
ground fault resistance.

100.0 means no injection for more than 5 s.

101.0 means incorrect frequency. Either the injection frequency on the REX 010 or the rated frequency on the
RE. 216 is incorrectly set.

102.0 means external open-circuit.

109.0 means that both the binary inputs ‘AdjREsInp’ and
‘AdjMTRInp’ are enabled.
No other codes will normally be generated, but if they are,
they are a diagnostic aid for the specialist.
MTR”:
The value measured for MTR is displayed when the input
‘AdjMTRInp’ is enabled.
During normal operation, the value entered for MTR on the
HMI is displayed.
