4.4.4 LOI password
A Local Operator Interface Password can be entered and enabled to prevent review and modification of
device configuration via the LOI. This does not prevent configuration from HART or external keys (analog
zero and span; Digital zero trim). The LOI password is a four digit code that is to be set by the user. If the
password is lost or forgotten the master password is “9307”.
The LOI password can be configured and enabled/disabled by HART communication via a Field
Communicator, AMS Device Manager, or the LOI.
