LOW SALT 

The es mated salt concentra on is lower than the op mum working range. The unit will remain in ON state 
and chlorine produc on will con nue normally. This message can also be displayed if the water is too cold, 
the electrodes are worn‐out or calcium has built up on the electrodes.    

 
SALT TOO LOW 

The es mated salt concentra on too low and out of the working range. The system will stop the produc on 
to avoid damage to the cell. This message can also appear if the cell is not properly connected. Press OK to 
confirm the message. The system will stop displaying the message and the unit will go to OFF state.  Once the 
problem has been solved, the user can turn the unit ON again.  
 

PAUSE 04:54  

When the system is carrying out a polarity inversion, the unit enters a pause mode and the remaining  me is 
displayed  on the screen. 

 

 

8. MENUS 

 

To enter the menus, press the MENU key and move up or down between the different sub‐menus using the 

 

 keys. To enter a par cular sub‐menu press OK. Once in a sub‐menu  use 

 o 

 to change a parameter, 

MENU  to  go  to  the  next  parameter  and  OK  to  confirm  and  save  changes.  Then,  use  MENU  once  or  more 

mes to come back to the Main Screen. 

 

8.1 Func ons menu 
 

8.1.1 Language 

 

Select the language and press 

OK. 

 
8.1.2. LCD Contrast 

This menu is no longer implemented . In order to be able to adjust the contrast even when an incorrect 
se ng  does  not  allow  to  read  the  screen,  a  poten ometer  marked  with  “

CONTRASTE” 

has  been 

mounted on the PCB, in the reverse side of the display. If you need to adjust the contrast, open the 
cabinet door and use a small screwdriver to turn it slowly un l the contrast is OK. 

8.1.3. Readings 

This is an only‐read screen that provides a list of system measurements. These values are used for di‐
agnose in technical support. 

 
8.1.4. 4‐20 mA Control 
 

Ac vate or deac vates the 4‐20 mA external control. 

 

8.1.5. pH Adjustment —op on 

Follow the instruc ons joined when the pH op on has been included. 
 
 

8.2 Status menu 

This is an only‐read screen that provides a list of system measurements. These values are used for diagnose 
in technical support.
