7.2 

REG-6S-100 and REG-12S-100 behaviour in ALARM mode 

In case that the 

REG-6S-100

 and  

REG-12S-100

 

detects an error during normal operation (see 

paragraph 3.2) the screen displays an error code and the behaviour of the device is as described in table 
7-.1. 
 

 Table 7-1: 

REG-6S-100 and REG-12S-100

 behaviour under ALARM conditions 

ERROR 

message 

Description 

Possible cause and REG-6S-100 and REG-12S-100

 

behaviour 

 

Measured  current  below 
threshold  (

0,05A  measured 

at the secondary side of CT)  

PosSible causes:

  TC low load or not connected.  

The  device  displays  the  RUN  LED  and  display  all  zeros 
flashing and not connecting any relay. 

 

Over-compensation

. 

The 

controller 

demands 

for 

stages  disconnection  and 
they are all disconnected. 

Possible causes:

  C/K not properly adjusted 

None of the realys will connect. 

 

Sub-compensation

. 

The 

controller 

demands 

for 

stages  connection  and  they 
are all connected. 

Possible causes:

  C/K not properly adjusted 

All the relays will remain connected, except the alarm relay 
if exists (see paragraph 3.3) 

 

Overcurent.

  The  measured 

current  is  20%  above  the 
rated current (primary of CT) 

Possible causes:

  C/K not properly adjusted 

Alarm  relay,  if  exists,  disconnects  (see  paragraph  3.3) 
Although  the  regulation  may  be  wrong,  the  device  tries  to 
regulate the PF normally. 

 

Overvoltage.

 

The 

measured  voltage  is  15% 
above rated voltage. 

Possible causes:

  Connection to a wrong supply voltage. 

Alarm  relay,  if  exists,  disconnects  (see  paragraph  3.3) 
Although  the  regulation  may  be  wrong,  the  device  tries  to 
regulate the PF normally.

MAINTENANCE  

REG-6S-100  and  REG-12S-100

  do  not  require  a  special  maintenance  program.  In  case  that  some 

adjustments  or  maintenance  might  be  necessary  it  must  be  performed  by  dully  qualified  staff  and 
respecting the required safety procedures. 

If  any  malfunction  of  the  PF  compensation  equipment  or  associated  protections  is  detected,  the 
equipment  should  be  disconnected  from  mains.  Before  performing  any  maintenance  repair  or  update 
operation  on  the  computer  or  associated  PF  compensation  equipment,  be  sure  to  disconnect  the  main 
switch and after disconnecting the switch, wait at least 5 minutes to ensure that the capacitors are totally 
discharged.
