Rapid trip with I3 = Off linst trip
Correct operating condition with
short circuit at high current
High ground-fault current, but
no trip occurs
Incorrect selection of the sensor Set internal or external sensor
Function G inhibited owing to high
current
Correct operating condition (see
use cases in the chapter that
describes the protection)
Display off (if present)
No auxiliary power supply and the
current and/or voltage is less than
minimum value
Correct operating condition.
Temperature outside range Correct operating condition.
The display is not backlit (if
present)
Current and/or voltages below the
display switch-on limit
Correct operating condition.
Incorrect current reading

cos φ reading
Incorrect connection between
isolation transformer and Ekip
Measuring
Check the connections between
the isolation transformer and Ekip
Measuring
Voltage parameter setting error Set the correct parameters
The expected trip does not
occur
Trip excluded
Correct operating condition. Enable
