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.
