Operation and Maintenance Guide

General safety instructions

Before carrying out any repairs or maintenance work on the electrical system, please disconnect 
the voltage to the control by placing the general power supply switch in the open position 
(O). Check the absence of voltage with a voltage detector before performing any operation. 
Replace any defective element of the control with original spare parts only.

If the correction is  required on the outside of the control, proceed as follows:
-  Safely switch off the control power supply in one of the following ways:
1)  Turn  the  OPTYMA

TM

  Control  main  switch  to  the  OFF  position  and  secure  the  transparent  

  polycarbonate front cover with a padlock.
2)  Cut off the power supply upstream of the permanently, using a padlock (on OFF position).
-  Display signs indicating maintenance in progress.

Maintenance  must    be  carried  out  only  by  skilled 
technicians.

Please observe these safety instructions before proceeding with maintenance operations:
-  Ensure that the control is voltage-free.
-   Prevent unauthorized personnel accessing the intervention area.
-   Display suitable notices to indicate “Device isolated for maintenance”.
-   Wear suitable work clothing (overalls, gloves, shoes, headgear).
-   Remove any item which could become entangled in any part of the control.
-   Ensure that suitable tools for carrying out the maintenance operations are available.
-   Ensure that the tools are correctly cleaned and greased.
-   Ensure  that  all  technical  documentation  required  to  carry  out  the  maintenance  work  is  
  present (wiring instructions, tables, drawings, etc….)
-   On completion of the maintenance operation, please remove all the residual materials and  
  carefully clean the inside of the control.

It is imperative that no additional parts are placed inside the control.

The manufacturer declines all responsibility in the event of failure 

to observe the points described on this page.

Maintenance

Maintenance  is  necessary  to  ensure  the  correct 
functioning of the control at all times and to prevent 
faulty components putting people at risk.

Maintenance  work  must  be  carried  out  by  skilled 
and authorized technicians who observe the general 
safety instructions.
