Information on the display 
Display information  
The display can basically be divided into three different display values/symbols. 
1
23
 
(1)  Current measured value or fault symbol 
(2)  Type of monitoring 
(3)  Symbols for the CO contact (right) and the semiconductor output (left) 
Meaning of the information on the display (with Mem = no) 
 
Symbol  Meaning 
12.5A  Displays the measured current 
n x I▲ 
  Flashing: Current is above the set blocking current 
I>>  
  Flashing: Fault current detected 
L  
  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 
Q 
  Not flashing: Semiconductor output closed, supply voltage connected 
  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
