Current measured value or fault symbol
Type of monitoring
Symbols for the CO contact (right) and the semiconductor output (left)
Meaning
Displays the measured current
Flashing: Current is above the set blocking current

Flashing: Fault current detected

Flashing: Cable break/phase failure detected

Flashing: Incorrect phase sequence detected

Not flashing: Relay contact 31/32 open, relay contact 31/34 closed

Flashing: Delay time (ON or tripping delay) running

Masked out: Relay contact 31/32 closed, relay contact 31/34 open

Not flashing: Semiconductor output closed, supply voltage connected
Q 
Flashing: Delay time (ON or tripping delay) running

Masked out: Semiconductor output open, supply voltage not switched through

Monitoring for current overshoot
Monitoring for current undershoot
Window monitoring (monitoring for current overshoots and undershoots)
Current is in correct range
A current overshoot has occurred
A current undershoot has occurred
