3.5.5 Write Protect
(1) Software write protect
The transmitter configured data is saved by using a
write protection function. The write protection status
is set to “Yes” when 8 alphanumeric characters are
entered in the New password field and transferred
to the transmitter. When write protection is set to
”Yes,” the transmitter does not accept parameter
changes. When the same eight alphanumeric string
entered in the New password field is also entered
in the Enable wrt 10 min field and transferred to the
transmitter, it will be possible to change transmitter
parameters during a 10 minute period. To change
the transmitter from the write protection ”Yes” status
back to write protection ”No” status, use Enable wrt
10min to first release the write protection function
and then enter eight spaces in the New password
field.
• Procedure to call up the display

information → Write Protect

mode (Yes: protected, No: not protected)
