Combining IFERROR and LEFT Formulas

I have a formula that looks like this

=IFERROR(B83,"OPEN")

So if a certain cell has an error it changes it to OPEN, but if it doesn't then it returns the values within that cell.

I am trying to make the cell also short the text that is being returned to 7 characters.

I made this formula:

IFERROR(B83,"OPEN"),AND(LEFT(B83,7))

However it does not work and instead returns an "NA".

Appreciate any help.
