Language 
If RIGHT is pressed three times when the start menu is shown, a menu is displayed in which 
the language can be changed.  
The different language files are stored in the application memory and are downloaded to the 
work memory. If a Corrigo has been reloaded with a program revision newer than the 
factory revision using E tool
©
, the controller will not allow language files to be downloaded 
from the application memory. This is because there is a risk that the language files are not 
compatible with the new revision. Therefore, you are limited to the two languages you have 
downloaded using E tool
©

Indication LEDs 
Status indication can be found in the upper left corner of the controller. For controllers with 
display, the alarm indication and change mode LEDs are located in the keypad area. 
Status indication 
Changing the battery 
Corrigo has an internal battery to ensure the operation of the memory and real-time clock in 
the event of a power failure. 
When the alarm ”Internal Battery” is activated and the battery LED lights up red, the battery 
has become too weak and needs to be changed. Nonetheless, due to a backup capacitor, the 
controller will function at least 10 minutes without power supply.  
Since changing the battery requires knowledge of proper ESD protection, as well as 
dismantling and opening of the unit, this should be handled by skilled service personnel.
