How to electrically erase the NVM
&
Under normal circumstances erasing the NVM is not necessary as
there is only one back up of the complete system configuration data held at the
panel. The NVM Initialisation should only be performed by a trained and qualified
engineer, as executing this command will erase all the data backed up at the
panel.
"
To completely erase the NVM you will first need to switch On the freeblock and
disable the hardware and software write protect. This will allow access to the
initialisation command.
