COMMISSIONING 

The  BLR-CX  comes  with  factory  settings,  which  allows  operation  in  400V  grid  without  any 
settings, if the connection is correct.  

After  applying  voltage,  the  display  shows  the  measured  cos

  and  displays  „Auto“.  The 

measured cos

 should be inductive (displayed by a small „i“ behind first line). With applying 

the voltage to the BLR-CX the discharge blocking time for the capacitors starts ( Factory setting 
75  sec.).  After  the discharge  blocking time the  regulation  starts.  Stepsizes  will  be detected 
automatically. Control exits which are not used, become adjusted to step status “Fix-Off” after 
three switching cycles without success. These outputs are blocked for the control. 

To display values, which are depending on the current, it’s necessary to adjust the ct ratio. 
This setting is not necessary for the control.  

 

FAQ during Commissioning: 

1) 

No indication AUTO -> the relay does not switch 

Cause: Relay is set to manual operation 
In SETUP/100 menu the selection for PFC is on OFF or HOLD, temperature is too high, 
current < 15mA, voltage or THD U is out of tolerance. 
 
2) 

Indication U ALARM -> voltage out of tolerance  

Check settings for nominal voltage (SETUP/Un) and voltage transformer (SETUP/Pt) 
 
3) 

Indication I Lo ALARM -

>

 CT current < 15mA 

Cause: connection error of CT; short-link of CT is not removed; CT-ration is too high compared 
to real current; no current 
 
4) 

Indication EXPORT -> kW export 

if there is no real kW export, voltage and current connection to BLR-CX has to be checked! See 
Wrong Connections / AI 
 
5) 

Wrong Cos j indication -> wrong connection  

voltage and current connection to BLR-CX has to be checked! See Wrong Connection / AI 
 
6) 

Steps switch in and then quickly switch out again 

See Stepsize Detection / Defective Capacitors 
 
7) 

Frequent switching of steps 

size of capacitors has not been completly detected
