Write protect switch
When the
Write Protect
switch (see page 6) is in the
ON
position, the transmitter is write-protected (and the Write
Protected icon is displayed – see page 19). This means
that only the
Read Only
access level is available to the operator.
When this switch is in the
OFF
position, all access levels are
available (
Read Only, Calibrate, Advanced
and
Service
).
Setting passwords
Passwords can be set to enable secure access at 2 levels:
Calibrate
and
Advanced
. The
Service Level
is password
protected at the factory and reserved for factory use only.
Passwords can contain up to 6 characters and are set, changed
or restored to their default settings at the
Device Setup/
Security Setup
parameter – see page
39 .
Note. The transmitter is supplied with blank passwords for the
Calibrate
and
Advanced
levels, therefore, the
Calibrate
and
Advanced
levels levels can be accessed without password
protection. It is recommended to set passwords for these
access levels.
Password recovery
Advanced level password recovery
To recover the
Advanced
level password, move the
Write
Protect
switch to the
OFF
position (see page 6). Select the
Service Access
level and enter the
Service
level password to
gain access. From the
Service
level, the
Device Setup
menu can
be accessed to reset the
Advanced
level password.
Service level password recovery
If the
Service
level password is lost, the only way to recover it is
by following the procedure to reset all parameters to the
factory default values as described in Appendix B, page 52.
This resets all parameters including passwords.
