v120 contrast

[Zorro1]

I know that SI 7 is contrast adjust but can this be set directly or is a ladder net required to change it.

Hello,

 

Thank you for using our Unitronics Forum.

 

SI 7 can be manipulated either through the ladder, or you can enter into "info mode" and change it.  To enter info mode, press and hold the 'i' button for 5 seconds.  When prompted for a password, the default password is '1111'.  Enter into "Data Types", then using the 1 and 6 keys, navigate to "System Ints" and hit enter.  Choose the address (address 7) and here you can manipulate the value.

 

Let us know if this helps.
